• How to invoke Web service for each row of a result?

  Hello
  I have an application that has a report on my old system tables. But for every line of this request, I have to go to Oracle EBS and return a value. The simple approach would be to create a link of database between these 2 databases, but for reasons of security in my company, which is not allowed. So, I built a Web service based on a PL/SQL function stored in the database of the EBS. The Web service has been tested and it works very well. This webservice takes 2 parameters, and returns a number. I would like to call it for each line of the report query result, the parameters passing the columns of the query. Is this possible?
  Thanks in advance!

  No, I suggested me not to use UTL_DBWS. Flex-ws-api is... Jason Comment should I say... much more flexible, functional and reliable.

• How to enable web services and search for printer email address

  I am trying to sign up for the monthly INK from HP.  As part of the application, they ask me a CODE.  However, I can't CODE because I am advised that my Web services are not enabled.  How to enable Web services so that I can complete my application?  Thanks for any help you can offer me.

  Hello

  What model of printer you have?

  Assuming your eprint-enabled printer, please follow the steps below to connect to web services and get your email from the printer.

  To find printers e-mail you need to enable web services from the front panel of the printer. It is normally a button on the front panel or an option in a menu.

  The printer will be connected to your WiFI network, and once the device is activated, it should display a page with a code composed of letters and numbers. It is the e-mail address of printers (when you add a @hpeprint.com to it).

  Once you have this, go ahead and configure a connected HP account and register the printer to your account. This will allow you to manage settings of the ePrint printer but also to track the history of the work.

• Invoke web service: Invocation - ALC-DSC-003-000 - error: content is not allowed in prolog

  I try to call a web service with the activity to invoke the Web Service in livecycle ES4 and it gives me an error of the Invocation.

  Here's the thing.

  I tried to use a paste of direct copy of a soap of SOAPUI request where it works perfectly fine. What is more, I tried using this same copy paste in the part of the test of the activity to invoke the Web Service in livecycle where it also works perfectly well.

  When I try to call the process, however, it fails.

  Any ideas on how to solve it?

  Here is the error log:

• How to call web services from other applications of E9?

  We have an obligation to look to the top of the account ID of a master data management application (no SFDC). The purpose of doing so is to find the account associated with a perspective on the basis of the corporate name, address, city, State, country... The application can expose a web service in search of account. I can call the web service of E9?

  Not directly.  A solution using Eloqua would create a cloud connector, but the code that connects to Eloqua and other web service live outside these two systems.

  Another approach, I recommend if you use Salesforce and the lead will do, there would be screaming to the webservice from Salesforce and have the info power back to Eloqua through integration of eloqua/crm normal.

• Web Service pulling back a clob to see as BLOB

  Hi all

  Thanks in advance for any help.

  My current project I have to use a web service in the Apex to display a document of our database manageable.

  With the help of webservices is new to me, so I'm struggling with this one.

  I got the webservice installed in the APEx and am able to back up some data using a collection but I ran to the top on the question with the clob field.

  so far, I have this in the source of the region

  select dbms_xmlgen.convert(xtab.fileContent.getClobVal (), 1 ) as filecontent
       , xtab."fileName"
    from apex_collections c,
            XMLTable(XMLNAMESPACES(DEFAULT 'http://www.stellent.com/Services/'),'//Get_FileResponse/Get_FileResult/downloadFile' passing xmltype001
              COLUMNS filecontent xmltype path 'filecontent/text()'
                    , "fileName" PATH 'fileName'
            ) xtab
  where c.collection_name = 'P10_GET_FILE_RESULTS'
  

  The name of the file is returned, but I don't know how to get the filecontent to be regarded as a BLOB from the results of the collection that is returned as below:

  <idc:Get_FileResponse xmlns:idc="http://www.stellent.com/Services/"> <idc:Get_FileResult> <idc:downloadFile> <idc:fileName>000_002075.pdf</idc:fileName> 
  <idc:fileContent>JVBERi0xLjQKJefzz9MKMTYgMCBvYmoKPDwvTiAyCi9UIDEyOTY5OAovTyAxOAovSCBbIDEwNzYKMjIzCl0KL0wgMTMwMDYxCi9MaW5lYXJpemVkIDEKL0UgODgwNjEKPj4KZW5kb2JqCiAgICAgICB4cmVmCjE2IDM1CjAwMDAwMDAwMTUgMDAwMDAgbiAKMDAwMDAwMTAwOSAwMDAwMCBuIAowMDAwMDAxMjk5IDAwMDAwIG4gCjAwMDAwMDE0NzEgMDAwMDAgbiAKMDAwMDAwMTU1MSAw....etc
  

  Thank you

  You would be better of trying to convert the Clob into a Blob, before adding the data to the collection.

  (IE store the BLOB file in the field of the BLOB001 in the Collection)

  From there on, APEX has a number of ways to view the files.

  It seems that is Base64 encoding... (including a standard way for the transfer of BLOB on SOAP/REST/text)

  APEX_WEB_SERVICE. CLOBBase642BLOB() comes to mind.

• How to consume web services REST in ADF - JDeveloper 11.1.1.6

  I have an ADF application deployed on Java cloud and I'm trying everything to try to get the data into it. I could not set up a connection to the Oracle Cloud server, to remedy this I created my db cloud instance RESTful web services. Now, I need to consume web services in my ADF application.

  Is there a way to link the ADF business components to RESTful web services in version 11.1.1.6?

  If not, then how is it possible to get data in your ADF application deployed on Java cloud? You cannot connect to the DB, you can not link to REST web services, how are you supposed to use your data?

  Thank you.

• HOW URL WSDL Web Service: Web Service call in the workflow

  have a 1 step, Web service workflow: call the Web Service.  I wish I could pass a string parameter to the url of the endpoint for the parameter of the URL of the WSDL in the Web service settings dialog box as oppose to the transmission of the actual url (http://machine/some_service.svc?wsdl).

  The reason is that we are moving the workflow between environments DEV, TEST, etc., we do not want to reopen the workflow in each env and update the DEV, TEST endpoint.

  I tried the following without success

  1. create a parameter of type String devURL

  2 by default, set the value on http://machine/some_service.svc?wsdl

  3 Goto service web appeal stage and set the URL of the WSDL to the /process_data/@devURL

  I get the error:

  java.io.FileNotFoundException: \process_data\@devURL

  I don't think that the URL of the WSDL parameter can even accept a parameter as the username + password settings.

  Is this possible?  OR if not, how can this be achieved?

  Under the Service Web Options change 'The Option' use 'variable' instead of 'literal '. Then click the Green + and it will create a variable of type WebServiceSettingBean.

  You can use a setValue before the stage of web service to set this variable.

  Thank you

  Hello

  You can create a client for the web service (project right click-> New-> company Tier-> Web-> Web Service Proxy Services),
  or you can create a Web Service data control (project right click-> New-> company-> Web Services-> Web Service level data control).
  In both cases you must provide the URL of the web service.

• How to develop the Table of Backing Bean tree nodes?

  I have a requirement where I want my table to be expanded all three nodes. InitiallyExpanded = True develops alone.
  Is it possible to have all the Backing Bean nodes?
  
  Code snippet will be very useful.
  
  Thanks in advance,
  TK

  For all nodes in a treetable can be expanded, you will need to add all the rows of the disclosedRowKeySet.

  (1) create a binding for the treetable in average managed code as "treeTable.
  (2) create a CommandButton named "Expand" (under the picture of the tree) and Visible set to false and create a link to a page named expandButton & in the get accessor for the commandButton control method, call the following method:

  public RichCommandButton getExpandButton() {}
  this.expandTreeTable ();
  }

  private RowKeySet disclosedTreeRowKeySet = new RowKeySetImpl();

  private void expandTreeTable() {}
  If (this.treeTable! = null) {}
  disclosedTreeRowKeySet = new RowKeySetImpl();
  Model CollectionModel = (CollectionModel) treeTable.getValue ();
  JUCtrlHierBinding = treeBinding
