>neither one of these error messages are at all helpful. this is a short example, i just spent a couple of hours with a much larger jsp determining what the problem was because i couldnt get any useful error message out of it. this is very annoying considering when i run something simple like this on tomcat or some other server i get much better error messages that actually TELL ME WHY IT WONT COMPILE.

Hmm, we get this error:
PWC6197: An error occurred at line: 1 in the jsp file: /123.jsp
PWC6199: Generated servlet error:
[javac]
/space/luehe/ws/sjsas91/publish/glassfish/domains/domain1/generated/jsp/j2ee-modules/123/org/apache/jsp/_123_jsp.java:12:
non-static method methodb() cannot be referenced from a static context
[javac] methodb();
[javac] ^
[javac] 1 error
which looks very reasonable.
