I was following the WTP-Tutorial-1 excersise and when I tride to invoke
the servlet via Sun Application Server 8.2 I got
java.lang.UnsupportedClassVersionError:
org/eclipse/wtp/tutorial/SnoopServlet (Unsupported major.minor version
49.0)
Presumably the server is telling me that it's j2ee runtime is unable to
run SnoopServlet because the base class, HttpServlet, is version 49.0.
However, the project is including jars from the appserver/lib directory,
so how can there be a version mismatch.
Does anyone have any idea on how I go about resolving this? Any help would
be greatly appreciated.

Ahh, I forgot to update my asenv.conf file to point to the latest JRE.
Thanks
