JAVA MAPPING LINKAGE_ERROR java.lang.NoClassDefFoundError

[Pranil1]

Hi all,

I am working on Java mapping. I imported java archive in mapping and after I execute the proxy to web service scenario in sxmb_moni, I am getting below error.

  <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

- <!--  Request Message Mapping

Hi Pranil,

                  What is the SAP-PI version you are working with?

If you are working in PI 7.0 or lower version the java mapping code has to be compiled  java2sdkse v 1.4.2_15, java2 runtime enviornment V 1.4.2_15.   In case you are working with higher version use j2se 1.5.0 to compile your code. Ensure you are using right library files also. For PI 7.0 its aii_map_api.jar. If its higher version of PI then use com.sap.xpi.ib.mapping.lib file as external jar files. The details where you will get these files are there in this link http://wiki.sdn.sap.com/wiki/display/XI/Where+to+get+the+libraries+for+XI+development

Linkage error results when there is a mismatch between java version of the compiled code and that expected by SAP-PI.

hi Anupam,

Thanks for your reply. I checked your link.

I am using PI 7.1 and I have used com.sap.xpi.ib.mapping.lib.jar files as suggested in the link.

Pls let me know if I am missing anything.

Hi Pranil,

              Check the java version you are compiling the code with. Is it j2sdk1.5.0 or not?

If not install proper java version inyour local system and recompile the code.

Thanks Anupam.

Hi Pranil,

You should use as local JVM the same JVM that your PI, and you must compile all the classes implied in the java mapping.
