I have a problem porting one of my webapps from 5.0.28 to 6.0.10. I've reduced
the problem to the testcase in this message. Briefly, the following test case
produces the exception shown below it. The class referenced in the error does
appear in the old JSTL jar that we are using. However it is absent in the
tomcat jars, and does not appear in the 1.6.0 JDK, either. Can anyone tell me
what I'm missing or should be doing to make this work?
Thanks,
-Greg
