hii everybody

i have deployed a project (.ear file) on websphere application server v6.

when i try to run the project, i am not able to run the project. The following error occur when i try to run it:

Error :

Error 500: java.lang.LinkageError: LinkageError while defining class: vigilance.Login Could not be defined due to: vigilance/Login (Unsupported major.minor version 49.0) This is often caused by having a class defined at multiple locations within the classloader hierarchy. Other potential causes include compiling against an older or newer version of the class that has an incompatible method signature.

Unsupported major.minor version 49.0

This message means that you are trying to run a class compiled with JDK 5.0 on an older JVM (Java 1.4 or older). That doesn't work.

Compile your source code with the JDK version that matches the JVM version on which you are running the code.
