Thanks for updating. This is the same error that you have asked about in your other question here How to use java 6 features in a java 5 environment, isn't it?

Basically the answers given to that question are correct and describe the solution your problem.

Resteasy specifics: The latest Resteasy distribution (2.1.0.GA) does seem to be compiled for JRE 6, but 2.0.1.GA is OK with JRE 5 (or the source is provided if you want to compile it yourself). Ideally, upgrade the version of java used on the server. Later versions have performance improvements if nothing else.

Finally, make sure you are not confusing the version of tomcat (5 or 6) with the version of Java (also, coincidentally 5 or 6).
