• How encryption works in the web services connector?

  Hi, I wanted to ask if someone could explain or point me to somewhere where its explained how encryption in Web Service connector (connector guide did not help) because I feel like there is a black box in the way that works part of the connector.

  This is what is happening to me.

  When I request an account the IOM sends to the SOA, a SOAP message with this field:

  user < __NAME__ > < / __NAME__ >

  Do0emq9XxVlYdbBxRUFSpciLqp77p6WYXQzATr8UysI = < __PASSWORD__ > < / __PASSWORD__ >

  But SOA sends a SOAP like it even though im using the oimcp/WS_CONNECTOR_OUTBOUND to decrypt the way that the Webservices connector Guide tells me to do section 5.1

  the user < USER_ID > < / USER_ID >

  Do0emq9XxVlYdbBxRUFSpciLqp77p6WYXQzATr8UysI < PASSWORD > = < / PASSWORD >

  < PasswordConfirm > Do0emq9XxVlYdbBxRUFSpciLqp77p6WYXQzATr8UysI = < / passwordConfirm >

  Somehow the DB records the real password not the hash, but if the size of the password in the DB field is smaller than the size of the hash I get a SQL error even if the

  password real has the right length. And change the size of the field in the DB is not always an option.

  Happents another odd thing, is that if I do not declare the passwordConfirm field in < property name = "password.field.xpath.locations" type = "xs: String" > / ns3:PASSWORD, / ns3:passwordConfirm < / property > even if the sending of SOAP by the SOA is always: "

  the user < USER_ID > < / USER_ID >

  Do0emq9XxVlYdbBxRUFSpciLqp77p6WYXQzATr8UysI < PASSWORD > = < / PASSWORD >

  < PasswordConfirm > Do0emq9XxVlYdbBxRUFSpciLqp77p6WYXQzATr8UysI = < / passwordConfirm >

  I get the error that do not match the password and passwordConfirm.

  And to make things even more bizarre if I wire the password, lets say, e-mail and declare this field as needed the decryption of the stored value is the hash. Even if the password is the normal password.

  Also, is there a way for the SOA to send the password in plain text?

  Hello Leo,

  If you have correctly configured oimcp/WS_CONNECTOR_OUTBOUND policy, there should not be any errors and it works without problem.  Unhappiness about using policy - is that the errors you will see when it does not work are not really useful to discover the cause of the problem.  In fact, the most useful tool I found the resolution of the problems with politics is WireShark.

  I used the strategy in multi-instance test scenarios and also support for several customers who try to use the policy.  From my experience, I guess that decryption is being ignored due to an error in your code. If WireShark gives you not with sufficient detail to indicate where the error is, I would say a SR in support to solve the problem more openness.

  Hope that helps,

  Amy

• How can I fnd my claim code and the reprint of the web services information sheet

  Hi, I have a HP Deskjet 3520 and try to put in place the eprint.  I read the suggestions on the forum and the FAQ but I can't locate the web services information sheet I need to reprint for claim code.

  Could not find anything under Printer Control Panel either. Please advise!

  Thank you!!

  Hi Chris88,

  Welcome to the HP Support forums.  I appreciate that you try to configure the ePrint on your Deskjet 3520 printer feature.

  If you have the inkjet printer Deskjet 3520 with a C8994 product number this printer does not have the ePrint service.  The Deskjet 3520 printer only has USB connection and ePrint to function the printer must have an independent internet connection through a wireless or a wired ethernet network.  I've included the specifications of the printer for your reference.

  If you have the e-all-in-one printer Deskjet 3520 then we obtain the claim code.  You can request the information sheet of web services from the front panel of the printer, and there the claim code printed in blue. Instructions on how to get it can be found in the section titled "to print a document using ePrint' in your on page 15 user's guide.  Please follow the instructions in step 1.

• Unable to connect to the Web Services Proxy/unused (a HP 7500 JO)

  Hello

  Here's the situation:

  Previous installer:

  .  I have connected my 7500 for the corporate network (IP = 172... series)

  .  registered the product with ePrintCenter

  .  used a PC under Windows to print (and scan) with the printer

  .  web proxy entry "webproxy.phila.gov".

  .  However, because homeland security rules, I could never work, so I just let it go

  Current situation

  .  has taken the home printer and set up on my home network, i.e.,.

  -using the 192.168.xx.xx series

  -Router broadband Netgear ' G' (1 years) set up at the 192.168.xx.254

  -SSID & encryption assigned

  -printer, the value 192.168.xx.155 (static IP address, the subnet and the gateway assigned as well)

  -My DNS is identical to the bridge and it works fine for all the internet access to this day

  -with the help of a PC and a Macbook Air to print and scan and everything works fine

  .  HOWEVER,.

  -Initially, 'web services' were active (carried over from when I was on the company neetwork?)

  ..  Are looking for, found and downloaded updates

  -When I went to hp.com ePrintCenter he showed the product as 'registered '.

  ..  He would'nt I would like to connect (with a name and a password I had used previously), or create a new account

  ..  I never remember getting an email address of the printer

  ..  and I had never been able to send anything to the printer to print because of my problem of network security

  -Yes, after trying all sorts of things, I:

  ..  I tried to get another email without success

  ..  tried to re - enable web services, but he said I need to 'proxy', and I discovered that he had always "webproxy.phila.gov."

  ..  I have reset the values by default web services and network values

  ..  I put the static IP address return address in (i.e., printer, subnet and gateway (it has nowhere to put in a DNS one))

  ..  printing and scanning to 192.168.xx.155 works fine

  ..  From my iPad AirPrint works very well

  .  BUT, I still can not online and therefore web server, web services are not enabled, therefore not ePrint

  -everytime I try, it says it needs a proxy

  - but I don't have a proxy installed on my internal home network bit

  -Comcast/Xfinity, my ISP, do not use a proxy

  So, I'm dead in the water.  I can't figure out how to get the web services enabled; I do not use a proxy, so I don't know how to go beyond this issue. How to regenerate address of the printer; and so, how do I connect an account on the ePrintCenter (or get them to send me my old account information).  I'm dead in the water and cannot use a feature most of my printer that I desperately want to be put in place and functional.

  Any help would be greatly appreciated!

  Tommy

  Problem solved, but I don't know exactly how I did it. However, I went back in and let the printer assign the IP address. Then I turned the printer off and on again. Last I kept pressing the button "Printer e-mail address", who has repeatedly failed, but then finally went through and print the 'printer' page, I quickly used to connect to the ePrintCenter and put everything in place.
  
  Now it's working.

• VIX file in the user interface designer receives the data from the Web service application that communicates with the SQL server database

  I created the Web service VI ("Mt-insolacije.vi"), which has two terminals of the input string (FROM / TO) for the dates of arrival and exit of two data terminals (table 1 d) from database (MS SQL server). This VI communicates with the database with functions of the database with a DSN and SQL query appropriate palette. There are two tables with two data (time and Insolation) columns in the database.

  This VI works when you run in Labview 2010, but when I used it as VI in UI Builder it returns no data.

  Could you please help me find a solution. Is it possible to communicate with the SQL server database in this way or there is another way?

  There are two files attachmet: Image of .vix file in Interface builder and .vi file ("Mt-insolacije.vi")

  Please help me ASAP!

  Thank you

  Ivan

  I found the solution problem is in the DSN. I've been using the user instead of DSN system DSN.

  It's important to create the system DSN if you want your VI of web service to communicate with the database.

  PS Please put feature bundle format timestamp and XY graph in the web user interface designer. It's complicated to trace data with datetime on X axis without them.

• The Web Service of LabVIEW error on restores model ESP

  Hello

  I was hoping that people would be able to help with the following problem:

  I'm currently on the Page Embedded Server (ESP), functionality of the LabVIEW webservices script and keep receiveing an error when you try to view a page.

  I think I put in place the Manager HTTP queries properly - buffered stream with headers

  The correct model is located and used as the page reaches the insertion point variable esp.

  I find that the AddressBook example works fine, unless I try and add an additional variable to the model, then the same error occurs.

  I have attached a sample project which shows the same behavior, and the error is less.

  Tested on LabVIEW 2014 (14.0.1 SP1) 32-bit on 64-bit Windows 7.

  Hi John_Neutron,

  I worked on your code today and we managed to reproduce and to fix the error you saw.

  The Web service name ESP file and rendering the page, but it throws the error because the variable you are trying to set was not properly declared. We managed to make the error go away by changing the file text with Notepad like this ESP.

  --------------------------
  <%
  //This is a server side comment
  // Variables:
  var myvariable;

  This is the test pattern

  
  
  It's the body:

  Here's the varaiable

  
  

  Variable: @@myvariable

  
  ---------------------------

  Before, you had / / in front of the variable (making a comment) and you don't have "var" to tell him you have said anything (it's all in the 4th line). Without the appropriate statement, the code generates an error when it is called.

• URL of the Web Service, LV2013 vs LV2012 length limits

  (* CROSS POST: http://lavag.org/topic/18435-web-service-url-length-limits-lv2013-vs-lv2012/ *)

  (* Please answer in this forum.  I scored the other thread for responses here. *)

  A that someone noticed a reduction in the limit on the length of the URL for the Web Services between the versions of LV 2012 and 2013?

  Under LV2012, a RESTful web service seems to accept URLS with lengths at least as long as 4096 characters.  With LV2013, the maximum length of URL seems to be 511 characters for RESTful web services as the project item. Unfortunately for me the project, I have converted just travel on this issue. My goal with posting this request here is my understanding of this limitation before deciding the best way to modify my code.  Certainly using POST instead of GET with a long URL is an option, but again, I am looking to understand the change in limitation before choosing a solution.

  To illustrate, I enclose three projects for the most part identical, demonstrating the issue.  In each case, the project contains a webservice consisting of a single VI, 'ComputeLength', which takes a string as an input parameter and that returns the length of the string.  The three projects are the following.

  1 LV2012 RESTful WebService.

  2 LV2013 RESTful WebService.

  3 LV2013 article project web service.

  The web service contains a single VI.  For the relaxing examples, the web service is started by selecting deploy menu of right-click Build specification.  For the example of project item, the web service is started by selecting start in right click menu position of work/WebService. The use of this example is shown with the following URL:

  (Note that the port is 8080 for both relaxing examples and 8001 for the project web service point if used in debug mode, which is the default value for the statement above.)

  http://localhost: 8080/webservice/computelength? string = 1234567890

  And the output looks like this.

  Workaround.  Apparently from 2013 of LV, there is a default limit of 512 to the length of the URL.  The default limit can be overridden as described below.

  Martin

  He is Brian in the technique of applications for National Instruments. I am following up about the 511 character limit in your Web Service HTTP request after the port number. After some research, I realized that the problem is related to a web site by default, the setting of the server called "LimitUri", which limits the maximum length of a URL. The default is 512 characters long that's why we are seeing this problem.

  There are several ways to modify the URL length limit depending on how you use your web service. If you publish the web service using the Application Web Server can change "C:\Program Files (x 86) \National WebServer\NIWebAppServer.conf" and add "LimitUri 4096" at the end of the file without the quotes.

  If you run the Debug Web server simply by clicking start on the web service, and then change "C:\Program Files (x 86) \National 2013\resource\webserver\niwsdebugserver.conf" and add "LimitUri 4096" at the end of the file without the quotes.

• deploy the web service to xp embedded

  Hi all

  I struggle to run a web service on an xp embedded system. The web service works very well in my LV 2011 development environment and I have created an installer for my main application it is the lvws file is included as described in web services FAQ:

  http://zone.NI.com/DevZone/CDA/tut/p/ID/7747#toc12

  After the installation on the target computer, I can't access the web service. Also if you call localhost:3580, then I get an access error.

  But in the System Control Panel administrative tools, I can see that the server system OR like many Web server OR Web applications are started.

  For further investigation, I added the 'Distributed System Manager' to my Installer. With this tool, I see that all my web services deployed on my development system, but on the XP embedded system with TEN target is listed.

  I installed my application for a professional reference XP system to exclude that the problem is caused by embedded XP. But the behavior is exactly the same. So far, I tested only local so that settings security like firewalls and ports system should pose no problems. But to be sure I have disabled the firewall without success... I can't access the Web service. I have often found the suggestions in the forum to check if the web service is enabled. But I am not already and then access to http://localhost:3580.

  Any ideas?

  Thank you!

  This help document is somewhat outdated.

  You see 2 different problems: 1) you can not display the Configuration utility and do not install Web using localhost:3580 2) your web service monitoring.

  For the first number-->

  You probably did not understand the "Interface Web NI 2011 infrastructure" in your Setup program.  The doc to help you mentioned does not tell you to do, because it is not necessary for your web service works. However, if you want to change one of the settings of your web server after the installation, you will need this extra setup program.

  For the second question-->

  You probably didn't get your Spec to build Web services as a source file in your Setup program.  The help doc says to put your LVWS file as your installation source, but this is not correct. You must include the technical article to build real web service as a source file (not the web service create out of spec files, like LVWS).

  Let me know if any of these will help you.

• change the frequency for the web service

  I'm under LabVIEW Web Service with an application following the method shown in the example of weather monitor. But my problem here is that I have to keep clicking the Refresh button, then the Web Service can only update the latest data for me. Can someone help me to set an example on how to let the page Web of the Web Service automatically update the value without pressing the Refresh button. Thank you

  First of all your customer needs to support it. If you use the HTTP Client in LabVIEW (GET.vi and so on) you cannot use this method. A normal browser should.

  Take a look at the address book example FindContacts.vi.

  The help topic linked in the previous post, you should get on the way as well. The news are scattered throughout the help file, but it should be possible to understand.

  Basically, there are two output options for a web service VI: Terminal mode as used in the example weather and fashion such Stream used in the example address book VI.

  Use stream mode and build the HTML page yourself, then sends it to the browser with Response.vi write. Somewhere in the top of the HTML page, you need to insert

  If you need to return a string like

  
  
  
  
  
  If your browser supports Refresh,
  this page refreshes in 5 seconds.
  
  And add some real contents here

• two-way communication with the web service

  I need help with a problem with web services on 8.6.  I do not know if this is possible.

  I have a web service that works very well.  At this point all it defines a Boolean value.

  For the test, I'm just using IE to see the data.  This works.  I can see the Boolean value change each time I send a 0 or 1 value through the URL.

  My problem is this: when I change the Boolean value, I can't read the value of another application of IE.  In other words, I want to be able to open IE twice in two different windows.  When I change a value of an Internet Explorer session, I want to see the value changes in the other session of IE (after refresh).  From now on, it seems that each session of Internet Explorer is a separate instance of the web service.  How can I edit a Boolean value, and read this variation by another IE session?

  My cause is hopeless?  Are web services 'read only '?  Any help would be appreciated.

  Bad form for the double post but the forum wouldn't let me edit my post:

  

  This VI is a good example of a global LabVIEW 2 style. The registry value at offset uninitialized loop will be persist appealed to the other of this VI. So when the game is true the value of data is stored in the shift register. When all is false the value of the shift register is returned unchanged. Make sure you have 'Keep VI in memory' checked in the configuration of your web service.

  You could do the same thing without parameters selected using two screws separated

• HP Photosmart 5520 - problems with the connection to the web service

  Hi, I'm trying to run the web service on Hp Photosmart 5520, but it does not work. Wireless printing works well, but he says that it cannot connect to the server and sometimes requires adding a proxy.

  I've set up a fixed IP and I used it in the IP (manual ip) configuration, I've implemented manula and gateway subnet mask (using the address of my router). I used the same primary DNS preferred (but also tried 8.8.8.8 and others)

  No question.

  Currently, I removed all of the proxy page. The error I get says that it cannot communicate with the server.

• OfficeJet 6500 a Plus: impossible to activate the Web services; roadblocks at all stages

  This printer is connected to my network by Ethernet. I want to activate Web services, so I can use ePrint.

  When I try to enable Web services from the printer control panel, I said that I might need to enter a proxy address. I'm not running a proxy server, but it is not possible around this prompt.

  There are posts on this Board indicating that Web services can be activated with a Wi - Fi connection. I unplugged the Ethernet cable and wireless enabled, but I was always invited address proxy information when I tried to activate the Web services. I disabled wireless and returned to Ethernet.

  A response to another post suggested updating the firmware to bypass the proxy server error. HP recommendation is to do it from the control panel of the printer. In the Panel menu control, firmware upgrade is the title of the Web services, which I can't because of the mistake of the proxy. So I downloaded the firmware and tried to install the update from my computer. The update found my printer on the network, but it is gray, saying 'Not applicable', under the State. I couldn't select it.

  In another post, someone suggested THAT DNS has been configured. I saw, through Server Web shipped by the printer, there is no configured DNS server (the printer is configured for manual IPv4). So via the integrated Web server, I tried to enter addresses (my domain controller, OpenDNS, Google) DNS server. With each of them, the SAP replied: "an error has occurred. (ipv4Page-400). Click 'OK' to go back. "There is no place to enter the DNS settings on the printer control panel.

  Web services require a Wi - Fi connection?

  Why the printer think there need a proxy address?

  The firmware update will solve the proxy error?

  I have to update the firmware, if the update statement indicates does not apply?

  What is another method for updating the firmware out of the control panel or from my computer?

  How to enter the DNS of the EWS information without getting an error?

  Charles:

  Thank you for taking the time to provide a complete response to my questions.

  I finally got the Web services enabled on the printer. What I had to do was enter the DNS settings in SAP to bypass the prompt for proxy information. Step I missed yesterday, when I got page not found error in the SAP, was that I had to do the secure version of the SAP ("https", not "http"), and then the EWS would accept my DNS entries. Once this is done, I went to the printer and could enable Web services without having to provide proxy information.

  The printer is now registered to hpconnect.com, and I can start letting my library to print patterns on my wireless network, that was my goal all along.

  Thanks again for your help.
