Re: Urgent. pls help me out
Now, is this really urgent? I'll see if I can help. I'd point you to the tomcat/webapps/examples directory. These are some examples that come with tomcat. You'll find a WEB-INF directory there with a web.xml file within. This is what maps URLs to actual servlet classes. You can create your own directory under webapps and make your own WEB-INF/web.xml there. Follow the directory structure shown in the other web apps that come with tomcat. Under WEB-INF you can have classes (for your class files), and lib (for jars your app might need, such as your JDBC driver). You can put your development directories anywhere you like. Your build process (make, ant, etc.) should put the class files into your webapp directory. Instead of creating your directory under tomcat/webapps, you could put it elsewhere (in your own development tree) and edit the server.xml file (in tomcat/conf), to add your own context. Again, follow the examples. You'll need to change the docBase to point to where your web app lives.

Thanks, I do set some values to prevent caching. response.setHeader(Pragma, no-cache); response.setHeader(Expires, 0); response.setHeader(Cache-control, no-cache, must-revalidate); I'll didn't really implement caching in the way you think. I just cache the Template object from loading my XSLT. I don't actually cache the result. I apply that template for every request (if my servlet gets called by the container!) I do want to move to Cocoon, but that won't happen for several months (at least not for the main app).

What caching the web server is and isn't allowed to do is fairly well defined in the HTTP protocol specification: RFC 2616. By the way, the still experimental RFC 2295 is fairly interesting in this area. You can also check out the JavaDoc for methods like HttpServlet.getLastModified(HttpServletRequest req). You can override this method in your servlet if necessary. Alternatively, as the HTTP specifications detail, you can use various response headers to indicate the response shouldn't be cached. A google search on no-cache HTTP headers will give a ton of information on this subject. You probably want to do the above anyways to avoid a proprietary solution to caching pages like you have used in the past.

request caching?
I've been using tomcat since 3.2.1 and use XSLT to take my servlet output and turn it into HTML. I wrote code to check the XSLT file modification date and auto-reload it if the file had been modified. So, in the browser, I could just hit reload and get updated XSLT. This is great for debugging and I would typicaly disable it with a property for production. My problem (and question) is about what happened when I moved to tomcat 4. We started using 4.0.4-le-jdk14 many months ago and I noticed that my auto reload doesn't work like before. My log says my XSLT was reloaded, but I don't see it in the browser unless I change the URL slightly. I can add a parameter and then I see the updated XSLT output. So, before I spend a bunch of time pouring over the source, can someone tell me if tomcat 4 (or the HttpConnector) looks at the incomming URL and gives a cached result if the URL hasn't changed?

Re: session startup
Hmm, I think you might be missing the point of a session. It is something that is associated with a client. If you want something initialized when the app starts up, you need to put something in a servlet.init() method. In there, check to see if that thing is initialized, if not, initialize it. For sessions, you'd call request.getSession(true), when the user first hits the app, to create the session for that client. You can check for a valid session by calling request.getSession(false) first, testing for null... David On 11/21/2002 12:22 AM, [EMAIL PROTECTED] wrote: Relating to the previous posting.

Re: Checking Tomcat's Memory
Kris is right. These parameters ought to be tweaked for servers with decent amounts of memory installed. On another project our company is working on, we had a machine with 8G (a Sun 4-way server). We were able to set up to 3G on JDK1.3.1. To documentation I found indicated using ISM, about 3.8 was achievable We did have problems and switching to 2G max heap worked. So, I'd caution those trying to use anything higher than 2G on 1.3.1. Perhaps 1.4 has fixed this. I know the documentation says the special memory settings (NewRatio, etc...) are used a little differently. Follow this link for more details; http://java.sun.com/docs/hotspot/index.html David Kris Schneider wrote: Sun's 1.4 server (not client) JVM can use a 4GB heap on a 64-bit SPARC box. Otherwise, I think you're pretty much stuck at 2GB. How much physical memory and swap space is installed? How much is actually available for allocation to the JVM when Tomcat gets kicked off? I also tend to adjust some of the other options. Something typical (for 1.3, some things have changed for 1.4) might be: -Xms512m -Xmx512m -XX:MaxPermSize=96m -XX:NewSize=128m -XX:MaxNewSize=128m -XX:SurvivorRatio=8 I certainly don't claim that those numbers are generally optimal, but changing them from their defaults can provide dramatic results.

(unless it was never intended to run standalone). I'd bet you could make
it work by messing with your classpath.

Re: Java Profilers, OptimizeIt or JProbe
I'll give my 2 cents... Ive used OptimizeIt to profile our app on tomcat. I know they provide a way to specify the servlet container for debugging web apps, but I never figured out why I needed to do that. I simply treated tomcat as any other app and profiled it that way. I had to take some of the stuff that tomcat.sh was doing and build that into my project params. I did memory profiling and was very pleased with the tools OptimizeIt provided.

Re: Tomcat and static content
Kapil, You could look at the apache access log. It will tell when an image has been served. There is now way (that I know of) to configure apache to trap all image requests that would be handled by a tomcat context. Is that what you are trying to do? If so, your web app needs to use paths that are not within the web app context. You can set up aliases within httpd.conf to make it easier to link images from the web app to some convenient path on your httpd server. Hope this helps.

Re: Apache plugin for Tomcat 4.0.3 for Windows 2000
Jamal, I don't remember where I got my mod_jk connector. Try searching on google. From what I read on the apache site, the compiled connectors (and source) should be availble on the ftp site (and mirrors). And, you are right, the ajp13 connector code is included, the mod_jk is the apache module that talks ajp13 with tomcat. David Jamal Najmi wrote: Do the mod_jk and ASP13 connector libraries usually come with the Tomcat 4.0.3 installation?

Re: -Xmx/-Xms Parameters, Where do they go???
I've added a line in my tomcat.sh that sets the TOMCAT_OPTS variable. You should really set -server since I've seen noticeable improvements over the -client option (which is the default). -server must be the first option. Then, use -Xms and -Xmx to increase your memory allocation. If you are using 1.3.x, you should look at -XX:NewSize and -XX:MaxNewSize for much larger mx/ms values. You can find more information about these at http://java.sun.com/docs/hotspot/index.html David bob McLaughlin wrote: The tomcat users guide states, that to improve performance, more memory can be allocated to tomcat in: Modify your JVM memory configuration. Normally the JVM allocates an initial size for the Java heap and that's it, if you need more then this amount of memory you will not get it. Nevertheless, in loaded sites, giving more memory to the JVM improves Tomcat's performance. You should use command line parameters such as -Xms/-Xmx/-ms/-mx to set the minimum/maximum size of the Java heap (and check to see if the performance was improved). QUESTION: Where does this command go? I assume the tomcat.sh or the startup.sh, but in which part of which one? Anyone doing this?

Re: ideas invited
Well, it sounds like you are running on some flavor of unix. I've set up tomcat servers on solaris and linux. For Solaris you can put the startup script in /etc/rc2.d or /etc/rc3.d. If you run on Linux. I found you need to put it in /etc/rc5.d. If you don't use linux, don't worry about rc5.d. The commands I've put in the top of the tomcat.sh are to set environment variables. An alternative would be write your own script that sets the variables, then calls tomcat.sh (forwarding the commandline arguments). That way, tomcat.sh won't be altered. Come to think of it, I'll probably start doing this myself...

Re: Monitoring Tomcat
I know it is not what you had in mind, but I wrote this servlet to allow
me to ping it to see if tomcat was still up. With 3.2.x (which we still
run on our production server), it would crash once every month or two
and I needed to be able to check for that (my script pages me if it is
down). I have a scripted telnet thing to issue an http get to my ping
servlet url.

Indeed, I would need a way to know about threads' managing and what happens to

my configuration and to prevent any crash. How to know if Tomcat's developpers
already talked about such a thing, and above all, how to know what they said about
this - I mean, do they think it's a useless function, or do they think it could be
usefull but not enough to waste time on this now, etc. ?

file access (security?)
I'm having a problem with TC4.0.3 (Win2K, JDK1.3.1)
I have some code that reads a property file and tries to load fonts
listed within. ClassLoader.getResource() is used to locate the prop file
and font files
I'm attaching the servlet test code. This code works fine under TC3.2.2
and TC3.3a
BTW, the files being loaded are in a jar in my WEB-INF/lib directory.
I've seen two problems:
1. when the font path contains a space, the resource URL is OK, but
calling url.openStream() returns null. (works fine in TC3.x)
2. even if the input stream is good (as shown in the log below), there
seems to be a problem creating a temp file.
Could problem 2 be caused by some security features that have been put
in place sincee TC3?
Here is my catalina.out (the relavent section)
file = fonts/Pgl_.ttf
resource =
jar:file:D:/work/pix.light/light/WEB-INF/lib/fonts.jar!/fonts/Pgl_.ttf
input stream = java.util.zip.ZipFile$1@5dd910
