Version Error after deploying the modified ESS Applications

[Former Member]

Hi All,

I have modified the ESS Payslip application through NWDS after the configuration of NWDI.

I have did small change in the coding and I build and deployed the application. When I saw the payslip application in portal I am getting the following error.

java.lang.UnsupportedClassVersionError: com/sap/xss/hr/rem2/cc/wdp/InternalCcRem2 (Unsupported major.minor version 50.0)

at java.lang.ClassLoader.defineClass0(Native Method)

at java.lang.ClassLoader.defineClass(ClassLoader.java:539)

at com.sap.engine.frame.core.load.ResourceLoader.loadClass(ResourceLoader.java:127)

In my machine I have installed the following JDK

JDK Version : jdk1.6.0_03 (client Machine)

: jdk1.4.2_11-b06 (EP Server)

I am on EP7.0 SP11, ESS6.0

Can anyone guide me

Thanks in advance

Hi,

Is your NWDS and the Engine compatible?

have you tried to repair project structure and classpath?

Hi Ayyapparaj,

Thanks for your reply.

When I deploy a simple Webdynpro application, it is working fine and there is no error. Only when I did modifications in the standard ESS applications, I am facing the following error. What could be reason.

Thanks again

Hi,

This could be an issue with the compatibility of the WD code generator for the ESS application. You might be using a latest version of the NWDI to modify the source which might not be compatible with the version which it was earlier created.

Hi,

Try to find the version of WD on which the ESS was created and use the same for modification

Hi,

One last thing are you using

"In my machine I have installed the following JDK

JDK Version : jdk1.6.0_03 (client Machine)

: jdk1.4.2_11-b06 (EP Server)"

Are you compiling the source with this JDK 1.6

Change this to JDK 1.4 from IDE Window->Preferences->Java

Problem Solved.

Error is due the problem in deployment.

Thanks All
