Error deploying webdynpro application - Bad version number in .class

[Former Member]

Hi,

I ve intstalled SAP NetWeaver 7.1 Composition Environment.But when i deployed a sample application given in NWDS.

Im getting the following error:

java.lang.UnsupportedClassVersionError: Bad version number in .class file

What could be the possibel reason for this error?

I have the server installed as a local host. How do i set the preferences for the SAP J2EE engine in the NWDS?

Hi,

I checked the Compiler Compliance Level. It is set to 6.0 by default.

I deselected the Use Default Compliance Settings and set the Generated .class files compatibilty and Source Compatibility to 6.0.

Even after that, iam getting the same error.

Hi All,

I also faced the same problem and even after changing the compliance level to 5.0 it did not get solved.

But finally I after changing the JDK path which the eclipse would use to start it worked.

The path can be changed in the SapNetweaverDeveloperStudio.ini file in NWDS CE which resides in the home eclipse folder.

Go to Window->Preferences->Java->Compiler->

Set the compiler complience level to 1.6

Hi,

Do i need to add JDK 1.5 only? We have added JDK 1.6. Is this version of JDK compatible with NWDS?
