Legend of Java in OSB return error

Hello

I get the error when having java challenge JAR of the OSB proxy below.

Entry is JSON query and output is in XML format.

Legend of java method 'public static java.lang.String XMLJSONConverter.json2XMLConverter (java.lang.String)' gave rise to the exception: null

Can you please suggest a solution for this problem.

You use XMLSerializer and JSONSerializer class.

Key takeaway point will be:

  • You are passing JSON string as input
  • You need parse this JSON string in JSON object using first JSONSerializer object
  • JSON object will be assigned to the XML using the XMLSerializer object string
  • Following the legend of Java, you will receive the XML string. So in the proxy, you can use the InlinedXML function to convert it to XML object.

Create a maven project in eclipse. You can use code and pom extracted from the link below. Once you generate the project in eclipse, it will download the required and dependent jar files mentioned in the link below. Now that the code works in your local computer. In order to put this code that runs in the server of the OSB, sort of eaisiest which I think will be copying those downloaded jar of your eclipse workspace in the directory/lib osb server. This is the class how imported into java code will be available when running at the OSB. Then just import the jar to java snippet of eclipse and import it into your project from the OSB.

I hope this helps.

  • Legend of Java in OSB not showing the available methods

    Hello

    I made a simple jar which contains a class with a static method that connects to our active directory. I use the spring to connect to the ad. The jar is built using maven. When I build the jar, I copied into a directory of Jar in my project of OSB. I created an action JavaCallout in which I can choose the pot, but it does not recognize my static method... There is no methods I choose!

    Can someone maybe tell me what's not here?

    I have compiled the jar using jdk1.5. IM using 11G ps2. The method takes a string as input and returns a list.

    Thanks in advance!

    try to use the Web Console of OSB directly, it is VERY stable and well tested. Here, you have option explicit to create a resource JAR - you can't fail.
    Once do you operate in the Web Console, just the sbconfig.jar to export and import it into Eclipse.

    Honestly when I need to do something that is not the Message flows edition, I much prefer the Web Console, it is very strong (I can't say the same of the eclipse).

  • OSB - legend of Java

    Hello world

    I'm fairly new to OSB and I would like to ask you a few questions about the legend of Java and the OSB. What I'm trying to do, is to call a Java method that returns a list of string and return that list of string as response via the proxy service. So far I managed to call the Java method through the legend of Java, but I don't know how to turn this list from the web service response string. I would like to know if there are any example or tutorial that I can follow.

    Another issue is that I'm vascular using sbconsole for development, but I found that some Developer's guide using Eclipse for development. So I would like to know what is the best way to do development for OSB. Thanks in advance.

    Kind regards

    K.Hein

    You can use Xquery transformations for this.

    However, your case must be simpler, and you can format the response in the Xquery expressions Editor.

    You can refer to the transformations of XQuery in the OSB "routing loan Tutorial»

    I click OK and Firefox loads as if nothing is wrong - but it's embarrassing

    Hello OleDad127, this error message is probably triggered by one of your extensions - please disable them one by one (and reboot after each step) to know that could be causing it.

    then please directly contact the developers of extension through the channels of support they provide - they can probably give you more detailed advice and are the only ones who can fix bugs or make necessary adjustments in the addon for new versions of firefox. Thank you...

  • HP Mini 1000MiE tranfer files - net usershare returned error 255

    My mini was just delivered. So I try to transfer files from my old Dell Latitude on Ubuntu to the Mini on a Netgear wireless router

    I put the files on the Dell to share. But the Mini does'nt find them well that he does not see a corresponding to the Dell printer Windows workgroup.

    The Mini does none of the files in the working group.

    When I tried to go the otherway to see if the Dell could see files shared on the Mini. I received a request to install 'actions' on the Mini and now when I try to share a file this error message.

    'net usershare' returned error 255: net usershare: cannot open/var/lib/samba/usershares usershare directory. Error Permission denied
    You may not create a usershare. Ask your administrator to grant you permissions to create a share.

    Now, I have two groups of windows work visible on my Linux machines but no files inside.

    How can I transfer files between two computers on Linux via a wireless network? It will not be a big problem.

    I am new to the Mini, but not in Ubuntu. I have not found how to open a command line terminal on this machine yet.

    I would really appreciate help on this issue.

    Transfer files between linux machines using a program called ssh. I found information on the web. It was not very difficult.

    Never got the two machines to connect using the shared windows resources, now I don't have to.

    Error 255 was a matter of a box under 'users' to allow file sharing.

    I also found the command line terminal hidden but available.

    Had a difficult start with the crumb of the Mini, but I am more familiar with linux OS crumbs now.

    Thank you for your update on the issue.

    If you receive Windows Update error 80073712 0 x or 80073712, it means that a file needed by Windows Update is corrupted or missing. Windows has tools that can help you solve this problem of troubleshooting. I would suggest trying the following methods and check if the problem persists.

    Method 1: Run the Windows Update Troubleshooter

    Method 2: Run the DISM tool

    1. Enter in the right edge of the screen and then click on search.
      (If you use a mouse, point to the lower right of the screen, move the mouse to the top and then click Find.)

    2. Enter command prompt in the search box.

    3. In the list of results, slide down on or right click command prompt, and then press or click Run as administrator.

    4. In the administrator: command prompt window, enter the following commands. Press ENTER after each command:

      DISM.exe / Online/Cleanup-image /Scanhealth

      DISM.exe / Online/Cleanup-image /Restorehealth

    5. To close the administrator: command prompt window, type Exit and press ENTER.

    6. Run Windows Update again.

  • Reg:GetMatchingArt() returns error (error no = 1146045247) in CS6 Plugin with Panel

    Dear friends,


    I am facing a problem, GetMatchingArt() returns error (error no = 1146045247) in CS6 Plugin with Panel.

    I read an earlier discussion on error no 1146045247.Then I try adding PushAppContext() before Create() metod of the Panel and PopAppContext() after Create() metod of the Panel, stil, the problem is not fixed.

    Please give me your suggestions to solve this problem.
    Note: prerequisite: I have to choose an art before calling GetMatchingArt() method.
    Plug type in GetMatchingArt() is kAnyArt.
    The nummatches Argument returns 0 and error (error no = 1146045247).


    Thank you friends.

    For CS6 and above the panels, you must call Push/PopAppContext (), but you do it in the procedure for notification of each item in the control panel user interface, not during the creation of the Group of experts.
