TC 4.0b3 Cass loader race condition or other glitch
I have pretty complex servlet defined as separate classes and as JAR files. If I specify load-on-startup, then I can get an exception Class not found arbitrary for any class from lib or classes directory, but likely for lib classes. However, it's likely happened after 2nd restart. It looks like OS started caching some class files and race condition or something other bad thing happened in class loaders. If I do not specify load-on-startup, all goes smoothly. I believe that it's related to reload problems recently reported. Could somebody confirm a similar behavior?

Re: Content-Length limited to 2^31-1???
You can always provide content length value using setHeader like methods to avoid int limitations. Tomcat shouldn't overwrite header value if it's already set. You can also use chunked out where content length simple ignored for files greater than 2GB.

The problem I am having is that tomcat 3.2.3 seems to (kind of) limit content length to Integer.MAX_VALUE (2^31-1 or 2GB). If I want to serve very large objects things do not work so well. I seems that ServletResponse.SetContentLength(int) is the prefered manner to sent the content length of a servlet response and that the default implemtation for the "HEAD" method in HttpServlet also is limited to the range of int values. My reading of the HTTP/1.1 spec does not indicate that there are any limitations to content length in the HTTP protocol. So my question is: Am I all messed up, or is Tomcat and the servlet spec/implementation sub-optimal? David Daney ___ Visit http://www.visto.com.

Hi !
I can't answer your exact question.
But for many purposes - other than reusing an existing servlet class
that you forward to -
request.setAttribute("name" , valueObject) ;
RequestDispatcher dest = context.getRequestDispatcher("...");
dest.forward(request,response);
will do.

Ensure that servlet has loaded
Does an option as load servlet by demand exist? I didn't find any API to just ensure that servlet has been loaded (init method is called) without actually hitting serve method. I know that using any static code in a servelt is against of rules, but sometimes it's helpful.

Re: How to control session timeout?
Call setMaxInactiveInterval(-1) for your session. You can recognize closing a browser over JavaScript in some cases and send a request to close the session. Call invalidate() in this case.

I am using Tomcat 3.2.1. For one application, I need very long session timeout, so all the JSPs involved will be able to access the java bean what has session scope. I would like the session invalidated only by closing the browser. I tried to set timeout in web.xml to a very long value, 360 Please let me know what else I need to do.

Re: Off topic: Single login for separate web applications?
One of solution can be having off web trusted connection between servers to verify the user. We use such approach.

Hi, Sorry for posting this off topic question. I would really appreciate any pointers into the right direction. What I would like to know is what you would need in general to create a single login to different web applications on different web servers (and possibly platforms)? I gues the servers would need some shared repository for login/passwords, but how would it be possible after logging in to one server to pass on this fact to the other servers? I hope the answer is as simple as the question, Wilko Hische - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED] ___ Visit http://www.visto.com/info, your free web-based communications center.

Tomcat 4.0 b2 and classloader
Great job Tomcat team! Now Tomcat starts much faster and private class loader provides excellent protection, but there is some bad thing. I didn't specify explicitly for my servlet/JSP XML parser classes, because they were already in class path. Now, I have to. I think, XML parser classes can be considered as system level classes without necessity specifying them for each servlet. Is there a possibility to provide some classes shared by all servlet/JSP including Tomcat itself? Or probably there is another solution? Thanks.

Re: Tomcat 4.0 b2 and classloader
The goal of JAXP is making a developer free from thinking what kind/vendor of XML parser he/she uses (in my understanding). Of course, I have copied these stuff to lib directory as got class not found messages. So, if I have 10 different applications running on Tomcat, then I have to have 10 copies of XML libraries. It isn't problem regarding disk space, but could be a problem regarding RAM. I like Sun's solution when you can copy some classes in trusted location and then use them without duplication for each application.

As shipped, Tomcat 4.0 does not expose an XML parser to all webapps, but this is easy to change: * If you want to use the JAXP RI parser, move jaxp.jar and crimson.jar from the jasper directory to the lib directory. * If you want to use Xerces (only version 1.3.1 has all the required support), put xerces.jar in the "lib" directory, and remove jaxp.jar and crimson.jar from "jasper".

server push how?
I've started using this amazing product, but found that server side push is not working. Why flush doesn't push anything to server? You probably ask me, how to implement reset() if you already sent something to server? Just raise java.lang.IllegalStateException in reset() after any flush(). But probably, I do something wrong? Please, help me. You can find source code of my application I work on at: http://drogatkin.openestate.net/webchat.htm and also check working binaries using another servlet engine.
