What does tomcat do to ensure that you're logged in
while using the j_security_check ?
We're trying to transition users from non-logged in to
logged in, but we've got a fair amt. of portions of
the site that should be accessible from both states
(non-logged in and logged in)
Is there something,
no, my question wasn't whether request.getRemoteUser()
returns null or not. HOW, specifically,
does tomcat populate that information using the
j_security_check and the security-constraint nodes in
the web.xml???

This may be more of a design question, but I'm
wondering if tomcat has anything in it's API that we
might be able to leverage to help manage dirty data in
a user's session?
When our user's login, we load, into their session a
w3c dom document that contains user-information, etc.
We use xsl
How do you set up multiple realms for different
webapps that are installed using ant?
We don't have any context tags in the server.xml
file other than for the manager app.
Our applications are installed using install from our
build.xml in ant:
install url=http://localhost:8080/manager;
Is there a way to tell what's going on in the heap
from within Tomcat?
I've tried putting JAVA_OPTS=-Xrunhprof:heap=all
but this doesn't seem to be doing it. Perhaps I'm not
using it correctly. Thoughts?
What I'm looking to do is cure an OutOfMemory

Has anyone ever seen the expected results in a browser
from their servlet, but when you view source, there is
a stack trace?
Not sure what would be causing this, but here's how
we're generating output to the browser:
public void printPage(HttpServletResponse response) {
yes, what I'm saying is that our servlet is actually
sending the output to the browser, but when you view
source of that output in the browser, it displays a
stacktrace. The browser, however, is showing what we
expect (the desired HTML).
Here's the stackTrace:

could someone guess as to why I can connect to our DB
(MySQL) from a standalone application (single, java
file using a Main()) successfully using the below
code, but when I try to do it from within Tomcat, it
fails w/ a nullpointer?
thanks -
GenericObjectPool connectionPool = new
I asked this on commons mailing list as well, but
perhaps someone here could shed some light into the
following:
I'm getting a nullpointer when trying to do the

Have you tried explicitly removing the search criteria
attribute from the session?
Look into
javax.servlet.http.HttpSession.removeAttribute, or
removeValue

I am using Tomcat 4.0.3 on Solaris with JDK 1.4.
I have been using the Persistence Store to save
? From the stack trace, seems your
persisting something do is
not serializable...I guest you will have to list what
you are trying to
persist

Has anyone does this successfully?
I am able to successfully have Apache authenticate
against a AuthDB file (configured w/ the mod_auth_db)
and I'm able to have Tomcat handle *.jsp files
successfully, but when I try to
request.getRemoteUser()
It gives me a NULL
any thoughts on this? Is there
How do you config. to use .htaccess and the
challenge/response/BerkleyDB AuthDBUserFile
from Tomcat?
I've got it configured to read from my AuthDBUserFile
correctly, but when I try to retrieve:
request.getRemoteUser();
from a JSP it is null.

Is it possible, from Apache 1.3 and Tomcat 4.1.10
(tied together w/ mod_jk)
to make a webapp the top-level (DocumentRoot) ??
For instance:
/usr/local/tomcat/webapps/MYAPP
I want MYAPP to be my document root and start serving
JSPs immediately, only using Apache if a HTML file is
requested and
Is it possible to override the location of where the
class files reside for Tomcat4.1.10 ?
for instance, I'd like to (from a JSP page)
call a useBean on com.companyname.util.Helper
but I'd like Helper.class
to reside in
deadline, so if it's as simple as say, swapping out a
jar file or something, that would be great.
Thoughts, or can someone point me to a FAQ on
upgrading like this?
Thanks,
Paul Tomsic
