HTTPProxyService using Tomcat error

I use to display items from RSS feeds in my SWF Flex BlazeDS. When I run the SWF file under Tomcat 6 Eclipse plugin, the SWF gets data from external web sites RSS feed, like Yahoo. However, when I deploy the file SWF on a test server running Tomcat 6 as a service, I get the following error:

I am using BlazeDS 3.2 libraries deployed to an instance of Tomcat nonkey in hand. Line 320 comes from the HTTPProxyService file is:

((HTTPProxyDestinationControl) destination.getControl ()) .incrementInvokeHTTPCount ();

All my other remote access services operate on the same channel of the AMF financial both environments. What could be causing the null pointer? Any help would be greatly appreciated.

I submitted a bug, and this has been fixed in the latest version of the trunk.

  • How to use the error at the level of the mapping table?

    Hi all

    Please tell me how to use the errors table in the mapping level or how to handle errors in mapping.
    I create a table of errors in oracle, but I don't know how to use it in the map.


    Thanks in advance.

    Kumar

    Hi Kumar,

    You use the Table of errors with the data rule.

    Error tables are used with logical errors (data rules) managers. Detailed description on the use of data rules is explained in the following document

    http://www.Oracle.com/technology/products/warehouse/PDF/OWB10gR2_ETLandBusinessRules.PDF

    In a nut shell, use of the tables of the error is the following.

    1 create a rule of data associated with a table (target table or a table in which you load data).

    2. use the table in a map as a target table.

    3 deploy the table and mapping.

    Now, in the schema target a single table will be created with the name _ERR. When executing a mapping data that violate the rule of data enters the error table.

    The following must be done to have the name of the wrong choice of the customers table.

    1. right click on the table and click Configure.
    2. give the name of the table in the section "name of the shadow table.
    3 pull out the table.
    4. use this table in a map. Now in the mapping on this table properties in the section 'Error Table name' the name of the table that is specified in 'the shadow table name' will be fulfilled.

    Thank you

  • Satellite A210 - cannot burn CD - R using iTunes - error 2131

    Hi all

    I know that I'm not the only person having this problem, but I get error 2131 when trying to burn CD - R help (v7.6) iTunes on Windows Vista with an Equium A210 TSST Corp TS-L632H CD - DVD writer.

    I tried all the usual things like the update of drivers, operating system, try different CD - R etc but no joy so far.

    I noticed a similar thread that was closed with the solution to use CD - RW instead of CD - R that unfortunately does not solve my problem because my audio CD drive cannot handle CD - RW (although the CD - R is very good).

    Practical suggestions anyone?

    Thanks in advance

    Hello, Alan

    At present, there is no solution, and you can only use CD - RW media. Sorry, but your situation when the CD player does not read the CD - RW media, you're just out of luck.

  • GET the file of cRIO using WebDAV - error (363510)

    Hi all

    Hoping for a little help with an error I can't cross. I am trying to get a file off my cRIO and onto my PC using the webDAV Protocol. I know there are other ways to do this, but really, Ide like to this way of working. I am sure that this is not a problem with my path of the file. The error says "Error writing to the socket" which makes me think maybe Windows prevents LabView to write the file on my local computer? I tried using the HTTPS protocol on port 443 so with the same result. One thing I am suspicious of is that I am connected directly to my cRIO on my secondary ethernet card and windows it is considering a "public network". I can't change that, but I have disabled the windows firewall, thinking that perhaps that had something to do with it.

    Thank you

    Corey

    I got it to work. Turns out that "local file path" needs the full path, including the name of the file that will be written. This is in contradiction with the help file for the VI GET of WebDAV. The help file says that simply give the path of the directory that is written to the file.

  • USB-6009 slow output signals using SignalExpress - error 200077

    We have a Council of USB-6009 and Signal Express version 3.5.0

    We want to generate low-frequency, analog and digital outputs to simulate some slow movement process.

    We have created the signals and their generated as output, put when we RUN the project, we get error 200077, which seems to indicate that we must use On Demand distribution of signals.

    If we choose On Demand, then the generate DAQmx says we have a missing entry.

    So, what method should be used with the slow USB-6009 to generate box (.01Hz and slower) analog and digital outputs?

    These are 2 of the projects, we tried - using On Demand, N samples, continuous, internal, and external triggering etc..

    Thanks adavance for your help...

    Welcome to the forums of Steve,

    I have good news for you.  I played a bit with the sweep and actually got a code facing up to generate a slow signal.  I went and tested it with the 6009 and he was able to run without any errors.  I joined here, but if you have to open (or anyone else in the future), here are some screenshots of how it works.  If this works, feel free to make the forum as resolved while others can locate a solution a little easier in the future.

  • ID package already in use, an error has occurred during the recording of output ' 1.1.0"to the database.

    Hello

    I currently have an application called "Apa Doanya' (id 33020976) for BB 7 and below. Now, I created another version of it for BB10. To publish this version BB10, I created a new application named also "Apa Doanya' (id 46317888), download the file bar, but not yet to introduce the new application for review. Later, I changed my mind, I want to release this BB10 version under the name of my current application so that I can keep the sides and the current download figures. So in my application, I added a new version, download the folder bar and increment the version 1.1.0. But I got an error when recording on step 5, he said:

    Package already in use ID
    An error has occurred during the recording of output ' 1.1.0"to the database.

    I tried several times but no luck. What has caused this? Is - it because I already download the bar file to another application (id 46317888)? Just to be sure, I remove bar app 46317888 file and download a dummy cod file (so that the application can be saved). Then repeat the previous step (add a new version and so on) but I still have the same error.

    Really appreciate any help.

    Yes, the problem is now RESOLVED. It was, I think, a bug/error on their part (support of the seller) so they erased the package id (I quote: "the package ID has been deleted.").
