  • 1.  Executing WTX From Java Program

    Hi,

    I am trying to run a WTX 8.4.0.3 (32-bit) map from Eclipse IDE java program. (Not Eclipse based WTX Studio)

    I have added dtxpi.jar, m4java.jar as dependencies to my project.

    My java program looks like:

    public static void main( String[] args ) throws MException
        {
       
        MMap.initializeAPI(null); // failing at this line
        MMap map = new MMap("MyFirstMap.mmc"); //fails at this line too if i comment out above line
        MCard card = map.getInputCardObject(1);
        System.out.println(card.getAllPropertiesXML(true));
        }

    When i try to run this java program, i am seeing this error:

    Exception in thread "main" java.lang.UnsatisfiedLinkError: <WTXinstall-location>\dtxjpi.dll: The specified procedure could not be found
    at java.lang.ClassLoader$NativeLibrary.load(Native Method)
    at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1807)
    at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1732)
    at java.lang.Runtime.loadLibrary0(Runtime.java:823)
    at java.lang.System.loadLibrary(System.java:1028)
    at com.ibm.websphere.dtx.dtxpi.MBase.<clinit>(Unknown Source)

    Steps i have done to resolve:

    1. Check the PATH variable, if it set correctly.

    2. Verified if dtxjpi.dll is present in the location.

    3. Copied dtxjpi64.dll file to check if my dll file is not correct. ( i copied this from my colleague system who have 64 bit version of WTX) 

    4. -Djava.library.path="${workspace_loc:edi-claims-modification-util}\lib;${env_var:DTX_HOME_DIR}" passed this as VM argument while executing the java program from eclipse. DTX_HOME_DIR is my WTX Install Directory.

    I am not able to resolve the problem by the above steps and any help would be aprreciated. Could anyone please let me know if i am missing anything?

    The description of your environment leads me to believe you may be using Java 64 bit, for which you will require a full 64 bit WTX API installation (you can't just copy one of the DLLs and hope for the best).

    If I am mistaken, and you're using 32 bit Java, then perhaps you could specify what product exactly you have installed, and from where you downloaded it.

    Details of the underlying OS would also help, as I will attempt to replicate using a VM if possible.

    Thank-you.

    Hi Paul,

     

    I have 32-bit java and WTX Application Programming needs a 64-bit java to be able to run a map from java program.

    Since i had 32-bit version it is looking for dtxjpi.dll and it is not finding required procedures.

    When i installed 64-bit version of java and run it, i think it read dtxjpi64.dll and the program is running fine.

     

    Thanks a lot for the reply. It really helped.

    Hi Paul,

     

    I am getting similar error. "no dtxjpi64 in java.library.path' while running wtx map via Java code (thru project jar). The same is working when I am running it thru Design studio.

     

    Using: Design Studio ver Version: 8.4.1.4 Build id: 7 

    Java: 1.8.0_51

    Could you advise steps needed to resolve this error. I have dtxjpi.dll present in my installation dir C:\IBM\WebSphere Transformation Extender 8.4.1

     

    Thanks.

    Ankit.

    As per the OP, you will require a full 64 bit WTX API installation.  Your Java is 64 bit, so it will be expecting to call WTX 64 bit.

    Thank you.
