I'm really not sure if it's a bug or not. Here's exactly what's
happening. I have an error handler
com.mhsoftware.cdaily.servlet.ErrorServlet.based on a class
com.MHSoftware.servlet.BaseServlet.
The base class has a method called dumpRequest which dumps an
HTTPServletRequestObject to a string for troubleshooting purposes.
When an error is triggered, the Error Servlet gets invoked and this
error happens:
java.security.AccessControlException: access denied

at javax.servlet.http.HttpServlet.service(HttpServlet.java:710)
MHS.jar which contains BaseServlet is located in
$CATALINA_BASE/shared/lib, while cdaily.jar, which contains ErrorServlet
is located in Application/WEB-INF/classes
I have a policy entry:
// Add files in the shared classloader hierarchy
// as well.
grant codeBase "file:${catalina.base}/shared/-" {
permission java.security.AllPermission;
};
If I create a simple JSP, and call request.setAttribute() followed by
request.getAttributeNames(), things work OK.
So, I'm really uncertain what's exactly going on. I'm kind of thinking
now that it's class loader related.
I have another class that I noticed was doing something similar. I have
a base object in MHS.jar, and in cdaily.jar, I have child classes. For
reflection to work in those child classes, I had to add a policy entry:
grant {
permission java.lang.RuntimePermission
"accessClassInPackage.com.MHSoftware.db.*";
};

It pretty obviously a bug. It looks like we need another PA :(.

George,
Did anyone get back to you about this?
I myself don't have much of a clue, as I haven't run Tomcat 5.5.x
Tomcat under a security manager.

I'm only starting to understand security policies, so I
would appreciate
some insights on what the best way to approach this issue is.
If it's a genuine bug, let me know and I'll open a ticket
on bugzilla.
