I've tried this outside Eclipse with Tomcat 6.0.26 on both Java 1.5.0_22
and Java 1.6.0_18:
SET JAVA_OPTS=-javaagent:C:\path-to-agent.jar
JSP's seem to work fine, but anytime you try to access a Servlet you get
the same thing:
javax.servlet.ServletException: Error allocating a servlet instance
org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java
:102)
org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:2

Can anyone else confirm?

Wrong conclusion. Try running Tomcat directly, not under Eclipse; the
problem you're having is most likely due to Eclipse insisting on doing
things its own way, ignoring configuration that you have set up. Deploy
your war to a stand-alone Tomcat and try it again.
