There is a problem in the current JSP support and Shing Wai was looking
into it and I believe the cause is known. However, the problem I ran
into was different. When I made JSP a module, webtier.jar now depends
jsp.jar, but jsp.jar is not included in the URLs returned from
getURLs(). To do that, jsp.jar has to be manually included in the URL
list when WebClassLoader was created. So my problem was solved, thanks
to Sing War for his help.
I think all modules that webtier depends on should be automatically
included in the URLs for its classloader.

It would be nice if Javac, when invoked programmatically using Jsr199,
can take a ClassLaoder instead of a classpath to resolve references, but
[1] is only a RFE, and is not fixed in JDK 6, sadly.
