java.lang.LinkageError: loader constraints violated when linking
Hi,
I am using Tomcat 4.0.1. I am currently using parser.jar for the XML
parsing. When I place the parser.jar in the WEB-INF/lib directory for this
webapp I get the error, however, if I move parser.jar to %CATALINA_HOME%/lib
the problem does not occur. I can't
figure out why this is happening.
Any ideas.

Yes, with the exception-type, if I give a fully qualified class name, it
works. Great! Thanks.
However, the 500 error-code is still not working while 404 works, I searched
everywhere and there doesn't seem to be any answer to that question.
%CATALINA_HOME%/logs/<severname>_log<date>.txt gives me the exceptions which
is great for debugging, but I was thinking it would be better to be able to
capture the 500 error and present a better page for the customers however.
In any case, thanks for the info, at least I am steps closer to what I want,
at the least, I could just define most of the exception-types that we get
here, but if 500 works it would really simplify things a lot.

Hey Ricky,
Struggling with similar issues to you, but might be able to help here. Your
<exception-type>CompileException</exception-type>
should contain a fully qualified class name. I have the redirection working
in Tomcat 4.0.2 with this. I would also suggest checking the
%CATALINA_HOME%/logs/<severname>_log<date>.txt log file, it usually has more
info if the redirection is failing.
Cheers
Drew

I have the following in my web.xml and if I bring up a non-existent page,
Tomcat4 correctly parses and presents the er404.jsp page, however, I have
not been able to get the 500 and the exception ones working. I always get
the Tomcat Error report with the dreaded 500 - Internal Server Error. Any
ideas?
