The problem, which I filed:
https://glassfish.dev.java.net/issues/show_bug.cgi?id=5980. Seems to
occur in other apps as well.
See attached email... (found it on a mailing list...) With liferay it
was hard to reproduce - but I would classify it as severe one...

Hi Glassfish Community,
i recently had a weird Jsp-compilation problem in the
Glassfish-Jasper-component (running inside a Jetty webserver):
A simple web-app (see
http://www.photonensturm.de/Testing.war) with the
following files:
/jsp/test.jsp
/META-INF/manifest.mf
/WEB-INF/web.xml
/WEB-INF/classes/de/Testing.class
/WEB-INF/classes/de/testing/Test.class
In test.jsp, i have an import of class Test:
<%@ page import="de.testing.Test"%>
But when the jsp is being compiled by the JDT-Eclipse-Compiler, i get the
exception:
org.apache.jasper.JasperException: PWC6033: Unable to compile class for JSP
PWC6199: Generated servlet error:
The import de.testing cannot be resolved
PWC6197: An error occurred at line: 7 in the jsp file: /jsp/test.jsp
PWC6199: Generated servlet error:
Test cannot be resolved to a type

It stumbles over the class de.Testing with the same name as the package. I
tested the web-app in Tomcat 6.0.16 successfully which is using the
jasper-jdt-component as well (at least i think it does as the library is in
there - but it might be different from the Glassfish-version).
I could track that down to a method in class JDTJavaCompiler:
private boolean isPackage(String result)
The argument "de.testing" is modified to "de/testing.class" and afterwards
is trying to open an InputStream by the classloader. Therefore the method
returns false (no package) under Windows-OS but should return true.
Hhmmm, is my analysis correct? Perhaps this error was fixed in a newer
version than the one that is used in Jetty (6.1.11 from June 2008). If not,
we should take a look at the JDTJavaCompiler in Tomcat-Jasper?...
Hope that someone can comment on this. At the moment i try to avoid such
filename-constellations.
Cheers,
Michael
