Just one more comment on the last note. I decided to declare the request
wrapper as an inner class of the filter. Now Tomcat will load the filter and
it's not until the filter runs that I get the class not found exception. In
this case, it says it cannot find the class that is inside the filter, and I'm
starting to wonder if maybe CAS has some security manager settings that might
prevent this class from loading with the request wrapper present. This is what
the log says:
SEVERE: Servlet.service() for servlet cas threw exception
java.lang.ClassNotFoundException: test.TestFilter$AuthenticationRequestWrapper
at
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1358)
at
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1204)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)
at test.TestFilter.doFilter(TestFilter.java:76)
Line 76 of the test filter looks like this:
AuthenticationRequestWrapper wrap =
new AuthenticationRequestWrapper((
HttpServletRequest)servletRequest);
The AuthenticationRequestWrapper is declared as an inner class of TestFilter.
Any ideas?
Thanks,
- Ole
