XFire 1.1 compiled with Java5, gives UnsupportedClassVersionError for JDK 1.4.0_04.

We are using JBOSS 4.0.4 and Java 1.4.

XFire 1.1 compiled with Java5, gives UnsupportedClassVersionError for JDK 1.4.0_04.

We are getting the following error. I have given the server log error also.

Please guide us.
