Hi,

It seems JDK version problem, Check the JDK version used for original deployment of DC

Also check the JAVA_HOME & PATH/CLASSPATH variable are set correctly.

Thanks

Hi Sandeep,

I have already checked that previousely I was using 1.5 locally and server had 1.4 so I installed 1.4 on my machine and changed the Java installation reference in NWDS and rebuild and deployed my applications

Also this problem is coming to webDynpro DC only if I try to develop WebDynpro application not DC it is working fine.

Thanks

Hi,

Check the shortcut from where you open your NWDS and try to change the JDK reference in that shortcut this might solve your problem.

I mean put the String something like this

<NWDS exe path> -vm "<your JDK 1.4 's Javaw.exe file path>"

Hi,

In 1st link from Rajat, Rene's reply says that for WD DC project the below solution worked (non-DC WD project was working like you).

The solution was to force NWDS to start with jdk 1.4 version. Just start the NWDS with following command

C:\...\IDE70\eclipse\SapIde.exe -vm "C:\j2sdk1.4.2_12\bin\javaw.exe" (adjust to your environment)

Kind Regards,

Nitin
