RE: Installation apache tomcat

Tomcat is pure Java, so provided you're running a decent Java virtual machine (the Sun one - *don't* use gcj to run Tomcat) the binary should work on your platform. - Peter - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: Optimized memory Parameter in Tomcat.
This totally depends on what your application does. So nobody on this list can say something about it based the information you give. 2GB is quite a lot of memory, so I think your application has plenty of memory unless it is a very memory hungry program. On 32 bits machines 2GB is a maximum amount per process for java code + native code, so giving java 2GB leaves no room for native code and makes your java crash with out-of-memory if the application uses a lot of memory for java objects. On 64 bits machines this limit is a lot higher than 2GB. You can also use jstat to few the realtime memory usage of your jvm. jps gives the process-id's of the java processes jstat -gc process-id 1000 gives the memory usage every 1000 miliseconds. See the documentation for more info about jstat. Greetings, Ronald.

RE: how to invalidate old sessions when new user access appl on same machine
Thats a problem in your server code... Session is binded to a connection (browser session) basically, not a machine. If you open a second browser (or a second tab) you should get a different session-id. Don't use JSESSIONID in url parameters, but in session cookie (unless you need to cross protocols like http - https) For security, you will have to bind an 'ending' date to the session's authentication.

Re: how to invalidate old sessions when new user access appl on same machine
Hello, you can use the Sevlet API. First call invalidate() on the actual HttpSession instance and then getSession(true) on the request object (HttpServletRequest) to start a new session. Nicolas Romantzoff schrieb: Thats a problem in your server code... Session is binded to a connection (browser session) basically, not a machine. If you open a second browser (or a second tab) you should get a different session-id. That's dependent on the browser and maybe the user settings. I'am using Firefox and I'am happy, that Firefox uses the same session in all windows for the same host. Don't use JSESSIONID in url parameters, but in session cookie (unless you need to cross protocols like http - https) Shouldn't this be transparent to the developper? For security, you will have to bind an 'ending' date to the session's authentication. Isn't the session timeout enough?

HelloWorld servlet, or just about
Dear experts, I love Tomcat, and I find all the people on this list kind, helpful, in short marvelous. I have dabbled in servlet filters before, but I never wrote an actual servlet. And now I need to write the tiniest of one. It just needs to return, as plain text, not Hello World, but the result of request.getUserPrincipal.getName(). That's it. Would anyone be as kind as to point me to a clean nice example, such that I could just replace Hello World by the above ? Better yet (but I don't want to abuse your patience), just paste the code right here below : (space intentionally left blank) Thanks very much. Angelica C.

Yeah, I got that too.
That's the problem though : which one to choose ?
Never mind, and apologies, I think I'll use the first one :
package test;

public class HelloServlet extends HttpServlet {
public void doGet (HttpServletRequest req,
HttpServletResponse res)
throws ServletException, IOException
{
PrintWriter out = res.getWriter();
out.println(Hello, world!);
out.close();
}
}
But now, a trickier question :
I already have a servlet filter, in front of a servlet which I need anyway.
Can I, in the filter, and based on some characteristic of the request,
return a response to the caller immediately, bypassing the servlet
entirely ?

Re: HelloWorld servlet, or just about
Actually this is very easy; when you want to pass the request down the
chain (i.e. into the servlet) you call the chain.doFilter() method. When
you *don't* want the request passed on, your filter just sets up the
response (status, header, etc.) and returns.

Re: HelloWorld servlet, or just about
André Warnier wrote: [...] Ok, let me explain why I asked these simplistic questions, not that you would think me gaga. I use a non-conventional database application, which wants a user-id as the content of a HTTP request header. Say DBUID: johnsmith To provide an SSO solution for that application, I previously wrote a servlet filter, which gets the authenticated user-id from tomcat, and transforms it into such a HTTP header, creates a wrapper for the request, to which it adds this header, then passes the wrapped request to the servlet that talks to the database. When the source of the user-id is a Windows domain, I add another servlet filter from the Samba people (see http://jCIFS.samba.org), which performs the HTTP/NTML authentication and sets the Tomcat user-id to the user's Domain user-id. Then my filter picks it up from Tomcat etc.. It all works very nice, and the jCIFS filter is easy to configure and just works. But now I have another issue : in front of that Tomcat, is an Apache, with plenty of things done by Apache in mod_perl modules, and only a few passed on to Tomcat. And I would need the user's Windows authentication to be done at the Apache level, so that it can be used more generally than for the links processed by Tomcat only. There are several Apache modules that allow doing an NTLM authentication at the Apache level. But either they do not work in some circumstances, or else they are complicated and really heavy to set up (for example, requiring Samba and winbind, which I don't otherwise need nor want). So my idea was to implement, at the Apache level, a simple mod_perl authentication module which just passes a request to the back-end Tomcat, to get the user-id as negociated by jCIFS, retrieves the answer, and uses this user-id to authenticate at the Apache level. The Apache user-id can then be passed on to Tomcat via mod_jk, for the requests that need Tomcat. I could do this either by creating a tiny specific webapp wrapped into the JCIFS filter (the reason for my original posting), or else I could arrange for the filter which I already wrote above to respond to those special requests itself, and bypass the database servlet in that case. (the reason for my secondary posting). I mean, I have the Apache and mod_jk and Tomcat and jCIFS anyway, so I might as well use them, and not complexify the setup by introducing more software and modules, right ? Now, from anyone who had the patience to follow up to here, any comments ?

Actually, let me add another question, linked to my earlier explanation : From a front-end Apache, I am issuing a request to Tomcat, with the only purpose of getting back a small string (a user-id). I would imagine that for Tomcat generating a whole response (headers + body) is heavier than generating just a set of headers. So can I, from the filter as before, generate a response consisting *only* of headers, among which one propietary one that would contain the string I want. I would basically need only a response with HTTP status line MyHeader: johnsmith (and no body) At the limit, it could even be just the status line, with my return string in the message part. I know that's pushing the HTTP protocol a bit, but this is a purely internal message, never sent back to a browser. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Tomcat 5.0 on IBM JVM 1.5
Hi. On a customer Suse Enterprise Linux system I have inherited a Tomcat 5.0, running on an IBM JVM 1.5. It runs, but the Tomcat packagers of Suse seem to have even more delight with softlinks than the Debian ones. (The common/lib and shared/lib have several hundred of them, never mind the usual conf and work and other suspects). For a couple of other Java applications, I had to install a Sun Java JDK 1.6 on that same system. Now I am wondering whether it is worth trying to fix the existing Tomcat 5.0 Suse package to have it use the Sun JDK 1.6, and get rid of the IBM JVM, or whether I should just leave well-enough alone and keep the two JVM's side-by-side. Anyone with any experience with this kind of thing ?

So take the code I posted, rip out all the HTML stuff, and just send the text
of the userid. Since it doesn't even have to be real HTTP, you don't even need
a header, just the userid as a string. You'll need some method of indicating
an empty string, unless you know the session has *always* been authenticated.

Redeploy leaks
Hi! As I had having OutOfMemory exceptions (PermGen) when redeploying an application, I started to verify things using Eclipse Memory Analyzer. I've discovered some real leaks, for example caused by the Java Disposer thread being instantiated using the Webapp classloader. After fix this, when I redeploy the application, Memory Analyzer shows that there are no non-weak/soft references to the undeployed classloader. But it (and the classes allocated by it) is never garbaged collected. I've tried different VM switches (-XX:+CMS*) and none make the classloader be collected. Thinking about word Perm (permanent) and some sources, I've done non-web testing and there a custom classloader *is* garbaged collected. So what could be the problem when running in Tomcat? I'm using Tomcat 6.0.18, JDK 1.6.0-10 (Linux and Windows) and Apache Wicket. I've not put any libraries in tomcat/lib, they are all on the WEB-INF/lib. Wicket uses ThreadGlobals, but I don't think this may be a problem, because Eclipse Memory Analyzer seems to show references from them, but it didn't show any references in my case! Increasing the permgen size is not something I'm looking for. I'd rather prefer to see unused memory being deallocated.
