My application uses the struts2 plugin for spring and works fine if
installed on a server with runtime java 1.5.
but if I use a server with runtime 1.4 (like Websphere 6.0) I receive an
exception:
java.lang.UnsupportedClassVersionError:
org/apache/struts2/spring/StrutsSpringObjectFactory (Unsupported
major.minor version 49.0)
Affects Versions: 2.0.8
Environment: jdk 1.4.2, struts 2.0.8, spring 2.0.3, struts-2.0.8-j4
Can you help me?
Best Regards,
Maurizio Catellani

Caused by: java.lang.LinkageError: LinkageError while defining class:
org.apache.struts2.spring.StrutsSpringObjectFactory
Could not be defined due to:
org/apache/struts2/spring/StrutsSpringObjectFactory (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.
