Is there any jar files(like jive_messenger.jar) that I shoud put into my project’‘s classpath? I have tried to use the jar command to make a jar file which include all the classes that showed in the jive javadoc,and put it into my project’'s classpath,then I wrote a programm just had one line like this:
XMPPServer server = XMPPServer.getInstance(); but when I execut it I got these exceptions:
［LinkageError while defining class: org.jivesoftware.messenger.XMPPServer
Could not be defined due to: org/jivesoftware/messenger/XMPPServer (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.
Dumping the current context classloader hierarchy:
==> indicates defining classloader
Thanks in advance, and I’'m sorry for my poor english.
