RE: simple context question for tomcat
Thanks Chris. It will take a bit of editing, but that will solve the problem since I'm using all jsp pages Although, in our production environment, our webapp has its own sub-domain, so jsp:include page=/commmon/header.jsp flush=true/ and a href=/common/header.jsptest/a both go to the same place. The problem is in my development environment (which I am not familiar with configuring subdomains or contexts...). -Original Message- From: Chris Novak [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 14, 2002 6:52 PM To: Tomcat Users List Subject: RE: simple context question for tomcat instead of writing: a href=/common/header.jsptest/a try: a href=%=request.getContextPath()%/common/header.jsptest/a When you are creating html, make sure the context path is given.

Gets in access log and java applets
I have a java applet that uses the jmf (java media framework). The applet works, but I notice in the tomcat access log that there is an individual GET for each class used in the jmf.jar file. Even worst, each time the user interacts with the applet, all those GETS are done again. All these individual GETS are causing the applet to be very slow. Is there a way to avoid having the browser going back to the server for each class needed in the JMF plugin module. Note that I just have a problem with the jmf module. No extra GETS occur for any other Java classes that are part of the standard Java run-time engine plugin. I'm including jmf.jar (the java media framework) in the applet tag... Does this sound like something expected (with applets) for modules that are not part of the standard Java run-time engine, or could I possibly have not installed the jmf appropriately?

Subject: response.sendRedirect
I have the following code snipet in a .JSP...
if (userStatus.equals (Failed))
{
session.invalidate() ; // Kill this
session.
response.sendRedirect(htmlHome) ; // Redirect
the user to our home page.
return ;
}
When this condition occurs, the response.sendRedirect fails with the
following message:
javax.servlet.ServletException: Response has already been committed
According to the response object documentation, the sendRedirect 'must be
called before the response is committed (in other words, before the status
code and headers have been written).' Obviously, the response has been
committed, else I wouldn't be getting the error!
My question - is the session.invalidate() doing this to me, or is it
something else that I am completely unaware of?
Thanks.

Does the :8080 means that the client directly serviced by something waiting in the port 8080 (in this case tomcat engine). if it is true, it means that tomcat work by himself to accept request, process and give response to client connecting to port 8080.

RE: Odd Apache+Tomcat errors
A number of us have been having similar problems with Apache 1.3.2x, Tomcat 4.0.1, mod_webapp.so, and Win2K. We haven't got to the bottom of that one either but it appears that the Windows port of the Apache-Tomcat integration is buggy. -Original Message- From: Mario Felarca [mailto:[EMAIL PROTECTED]] Sent: Monday, January 07, 2002 1:38 PM To: [EMAIL PROTECTED] Subject: Odd Apache+Tomcat errors Hello, I have a problem and I was wondering if anyone could give me some ideas or information about a possible solution. I am running Apache 1.3.20, Tomcat 3.2.3 and using mod_jk on Win2k. We are accessing our servlets through https, and every once in a while (i.e. not all the time, but often enough to be annoying) a click on a link that goes to the servlets will result in a page not found or a blank page. In looking at the logs, it appears as if the request doesn't even hit Tomcat. If I click on the same link immediately afterwards, it works fine. Also, every once in a while, when I get a blank page or page not found, I will also get a Windows dialog for an Apache.exe error saying it has crashed. However, watching the processes, the webserver itself does not go down. In fact, immediately afterwards, I can click on the link again and it works. Is this mod_jk crashing? Has anyone experienced this? Any information or pointers would be most appreciated. Thanks, Mario- _ Do You Yahoo!?

directory organization advice
Can anyone give me some quick advice on how to appropriately organize my directory structure to have Apache serve up the static content (images and html files) and Tomcat serve up the dynamic content (JSP files,etc). For simplicity, consider the sample webapp (myapp) given in the tomcat documentation consisting of the following files as deployed on my win2000pro box (ignoring the servlet for simplicity) C:\tomcat\webapps\myapp\index.html C:\tomcat\webapps\myapp\hello.jsp C:\tomcat\webapps\myapp\images\tomcat.gif With Tomcat plugged into Apache, does Apache automatically serve up the static content (index.html,tomcat.gif)when it is located under the myapp directory? Or do I have to place the static content somewhere other than under the webApp directory for Tomcat. Would I need to place index.html and images\tomcat.gif under the doc-root for Apache outside of the webApp for Apache to serve it up? Another way of asking this is when I deploy the myapp sample with Tomcat plugged into Apache and the static content is served up, is it Tomcat that serves it up or is it Tomcat that is serving it up when the static content is located under C:\tomcat\webapps\mayapp...

RE: tomcat-apache win32 integration problem with 100% CPU utilization
When I installed the sample app myapp from the tomcat 4.0.1 documentation, and tried to run it with Tomcat plugged into Apache, I had the problem mentioned below with things locking up whenever images needed to be served up (especially whenever you hit the refresh button on the browser). Note that this problem was in my development environment where the browser, apache and tomcat were all running on the same machine. When I used a different machine to browse to the website, I didn't have the problem. That may be one solution to the problem. Just browse to the web site on a different machine than the one hosting the software. But most people develop with everything running on the same machine There must be something going on with one software component (the browser???) getting a lock on something and preventing another software component from getting to it...

I'm developing a Tomcat 4.01 website and need to make some high level decisions. Can anyone give some quick advice? 1. Should it run on Windows or Linux? I suspect I should use Linux but is Windows a viable option? 2. Should I plug Tomcat into Apache web-server or is the build-in web-server for Tomcat good enough? 3. Is mysql the best open source free database choice? 4. Can anyone recommend hosting facilities, preferably in Northern Virginia?
