JAVA mapping error

[Former Member]

Hi All,

I am getting the below error while executing a JAVA mapping.

******************************************************************************************************

I have tried compiling the code in the same JRE as the one in PI. Still it is not working.

Please suggest.

Regards,

Yashwanth

Does your target contains such an element? XMLNSTagCreate1/XMLNSTagCreate1?

Looks like Java is complaining about the class related to this name is not present. Are you not using XML DOM or some other supported parser to create the XML?

Hi all... thank you for the replies.. I have compiled the code in the same version of JRE as the PI version...

Hi Vijay,

I also felt the same but as I do not have much knowledge in JAVA, i could not track it further.

below is the code for the mapping... would you mind if I ask you to have a look at it and let me know where the error is..

thank you so much ...

Why do you have two main methods? only one main is allowed . Also make sure you close the curly braces accordingly. Do you see any compiler errors? Abhishek's error notification can be resolved at compiler level itself.

Check what Ryan Crosby said.

How are you deploying the class file in the ESR?

I think problem is in jar file, that you export from your development environment.

Check your Imported Archive and path in it.

Redeploy class file.

The problem got solved. The error was that the class and the JAVA files were put in a folder and the folder was zipped. Hence the error.

The files together were zipped without the folder and it worked fine.

Thank you all for your replies.

Hi Yashwanth,

There are no errors in the above Java code. Please compile it with JDK1.4 (it compiled successfully for me). Please follow the 3rd screenshot in this [Link|http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2FgettingStarted%2Fqs-with-j2se50.htm], there select JDK 1.4.

Hi Yashwanth,

How are you deploying the class file in the ESR? The error you are getting is indicating that the expected compiled .class file cannot be found and thus cannot be executed at runtime. In your namespace definition you should look for an object under imported archives that contains your .class file. This file should be named XMLNSTagCreate1.class

Regards,

Ryan

[former_member200962]

it does not seem like a JRE issue neither a tag-name issue.....you seem to have a class by the name XMLNSTagCreate1 which the compiler is not able to find (or more like you are referencing class in a wrong way).

public class XMLNSTagCreate1 extends DefaultHandler implements StreamTransformation {
.
.
XMLNSTagCreate1 test = new XMLNSTagCreate1();
.
.
XMLNSTagCreate1 test = new XMLNSTagCreate1();
}

You sure that above statements are correct??

[RaghuVamseedhar]

Hi Yashwanth,

Compile with JDK 1.4, it should work.

If your Java Mapping is using JDK 1.5 classes, compile with lower release than PI JRE.

looks JRE version issue:

[former_member181962]

Hi Yashwant,

Check the java version of your JRE vs the java version that your PI system uses. They might be different.

Best Regards,
