Re: while deploying in jboss getting Unsupported major.minor version 49.0

Please have the follow check:
Windows --> preferences --> Java --> Compiler --> JDK Compliance --> Compiler compliance level:
If it is 5.0, change it to 1.4. It seems that Eclipse will set some information to the class file according to this attribute setting. And the 5.0 makes every compiled class file attached the JDK 1.5 symbol. that's why the "Unsupported major.minor version 49.0" problem accurs.
