RE: Shutting down Tomcat on HP-UX
Hi, This is one I'm having problems with too. When using HPUX11.00 and java 1.2.2_04: * With tomcat3.1, I needed 2 shutdown commands. * With tomcat3.2b6, I now need 3 shutdown commands. This difference is without changing the JVM, so it's clearly something to do with tomcat code. It's very consistent (consistently annoying). Exactly the same webapp shuts down correctly (on first shutdown command) when run on Solaris, (java 1.2.2_06) so it's *also* something to do with the JVM or platform.

It's not clear whether it was a Tomcat change or a jBoss change that caused the problem, but we are aware of it. As a workaround, you can manually load the jndi.properties file into a properties object or the system properties. Also, the new embedded tomcat service should solve that problem if you're running the two products in the same VM, but the directions for that are not yet in the manual. For the benefit of the Tomcat folks, I think the JNDI code uses getResources to look for jndi.properties, which is not implemented in AdaptiveClassLoader, but I'm pretty sketchy on that, and I don't know why it would have worked before (unless this was caused by one of the Linux JDK 1.3 updates?).

AW: Request for clarification - I.E. Tomcat mod_jk installed in Apache
If you would serve your static content by apache and call your dynamic pages directly from tomcat you have to think about the following: An uncomplete braindump of mine: - You loose the common access.log for all requests - You would rely on tomcat as a HTTP server and the HTTP implementation is possibly not as stable as apaches. - Some clients of your server may not even get your dynamic content, because some sysadmins block HTTP Request from non standard ports in their firewalls - apache has some features that are not available for tomcat standalone (mod_rewrite, virtual hosting) - I think it is not a good policy to put the port number in the pages. So you have to implement something to deal with this. - You have two dedicated servers with their own administration. -Ursprüngliche Nachricht- Von: John Bateman [mailto:[EMAIL PROTECTED]] Gesendet: Donnerstag, 2.

Re: Trouble with taglib
If you are running on a win32 platform with Tomcat 3.2b6 you might be suffering
from the same problem I found yesterday when I grabbed 3.2b6. The problem is
caused by the goofy way win32 handles upper/lower case in file names. To fix
the problem edit src\share\org\apache\tomcat\util\FileUtil.java starting at
line 197:
if (!realPath.equalsIgnoreCase(canPath)){
int ls=realPath.lastIndexOf('\\');
if ( (ls 0) !realPath.substring(0,ls).equals(canPath) )
return null;
}
Change the realPath.equals(canPath) to realPath.equalsIgnoreCase(canPath).
There was even a comment on line 196 which mentions checking ignore case on
windows.
Once I made this mod, everything worked great. I'm not at all sure this is the
"right" way to fix the problem but it does seem to work.

RE: including files from JSPs (Better Way To Handle Errors?)
Juan,
If you are trying to include an error page everytime that there is an
error there are much better ways to do it. The way I handle error is to
create a jsp something like this...
"/ehandling/index.jsp"
%@ page import="com.netstat.util.*" isErrorPage="true" %
!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
html
head
titleStallion Leather - World class quality exceeding customer
expectations./title
%@ include file="../includes/pagetop.jsp" %
%
/* Print the data to the users screen. */
%
div align="center"
There was an error:brbr
%= exception %
/div
% /* Print the bottom of the page. */ %
%@ include file="../includes/pagebot.jsp" %
/html
That is just a very simple error page. Then I have all other jsps in the
project declare there page attribute like this... %@ page
import="com.netstat.util.*" errorPage="/ehandling/index.jsp" %
This setup uses jsps built in error handling. This way if a page throws an
error you did not expect or code for the user still gets a nice looking
error page with a message they can report. Also, now instead of including an
error file everytime I look for error I can just do something like this.
try {
do some code
} catch (Exception e) {
throw new Exception("There was an error of some kind.br"
+ "bAdditional Information:/b " + e.getMessage());
}
This has worked very well for me and it allows me to changed the look of my
error messages in one place and also reduces the amount of code in each
individual jsp by a significant amount.

I got some good advice from the mailing list about how to set up multiple instances of Tomcat.) Now the client has further informed me that when they provide a maximum heap value of more than 700 Megs, Tomcat is unstable, and invariably crashes after a while. They are running Tomcat 3.2b2 on a Sun Sparc machine using Solaris 7 (I don't remember the machine model number but they've only had it for a month, and it's one of the biggest machines you can get). They actually have more than one machine of this type (4, I believe), all of which are exactly the same. The client is in another city, and therefore the communication is sometimes a bit spotty, so I don't have more detailed info on the nature of the crashes, but it seems to vary. Unfortunately, our test machines here only have 512 Megs of memory, so I can't duplicate the situation either. My question is: Has anyone else experienced this? Does anyone have an idea why this should be an issue? Also, does anyone know of any stability/performance issues that were resolved between 3.2b2 and 3.2b6? If need be, I suppose that we could just have more Tomcat instances, but it seems to me that this shouldn't be necessary. This site only has one servlet at the moment, but we have to have a servlet to facilitate our applet/server communication, and we anticipate very heavy site usage. We're already getting thousands of hits a day, and the client hasn't even started advertising. We are keeping the memory below 700 Megs, but we have had the servers go down a couple of times already (I'm waiting to receive a Tomcat log file while I'm writing this note). I feel that in terms of performance tuning, we haven't even scratched the surface, but I nevertheless get a bit nervous when I hear about servers going down. Despite the heavy traffic, the servlet usage is relatively light. A user may stay on the site for 10-15 minutes, but they only need to access one servlet, at the end of their session. This is done in order to transmit data from an applet to the server, which can take about 20 seconds, but may take longer because if the servers are occupied, they will be queued up behind other users. Due to this setup, we figured that we could get away with using Tomcat as opposed to some other, more industrial strength, servlet engine. (Also, I'm a fan of open source, and I personally like the idea of using something like Tomcat.) This is probably all a bit vague, but if anyone has any suggestions or opinions on what I should be looking at to resolve this, I'd appreciate them. Thanks in advance.

Re: Why run multiple tomcats?
From: "Rick Anderson" [EMAIL PROTECTED] The documentation for Tomcat seems to recommend that for a multi developer environment everyone run their own tomcat instance and each developer having their own server.xml file. Isn't there an easier and cleaner way of doing this? I'm currently running each of my sites with separate tomcats with their own separate server.xml files, and I thought it was actually a pretty clean way of doing it, particularly for development, as everybody essentially has their own server that they can use/crash/misconfigure without bothering anyone elses work. Well, with each webapp getting it's own "/lib" and "/classes" directories and such (although this is part of the servlet 2.2 spec, so not unique to tomcat), tomcat has already gone a long way toward giving each development its own sandbox. About the only thing that I can think of off the top of my head that's still server-wide is the users/passwords. If tomcat could make that localizable, it seems that you'd only need to run one server. As far as users being able to crash the server without affecting anybody. tomcat itself should crash when a webapp misbehaves. - Joe

Tomcat3.1 Solaris2.7 - shutdown.sh does NOT work?
Hello, I just installed Tomcat 3.1 on my solaris 2.7 machine. I have set my TOMCAT_HOME and JAVA_HOME. It started up fine but when I went to run shutdown.sh it did not shutdown the listener. Everything seemed fine; it displayed the 'Using classpath...' message from tomcat.sh and then the typical 'Stop tomcat'. There were no errors or any other sign that would indicate the listener (port 8080) did not shut down, but it was still running. I had to kill the process manually. This has never happened on my Win98, NT, or solaris 2.6 platforms. Has anyone seen this behavior?? Thanks, Peter Len
Re: Tomcat ISAPI
Some other people have reported the same problem in this list, and a couple of solutions have been posted. To save you time searching the archives: - Be sure the first line of your page is an HTML tag (put HTML ...) NOT a JSP tag. The point is that lines with JSP tags appear in the output as empty lines (CR LF) and it seems that there is a bug in IIS when serving pages in Chunk mode.. -If the first fails, be sure you are closing all JDBC objects, especially connections, if you are not using a connection pool.

Re: Why run multiple tomcats?
Tomcat should never crash when a webapp misbehaves, it should just stop the webapp from doing any harm in the first place, it should just report an error and then move on. Tomcat documentation shows how to configure to serve virtuals, although its a little vague. What I don't understand is why can't you map an app directly to a directory instead of having it mapped to a base directory and then putting everything within the proper place i.e.: /mapped_dir/WEB-INF /mapped_dir/WEB-INF/classes etc. etc. The docs never realy explain as to why this setup was chosen instead of the old JServ way of just telling where the servlet is or should be.

RE: servlet mappings???
If you have everything correct, the re-direction should work when you use port 8080, but fail on port 80 because Apache doesn't know about the change. You can tell Apache in either or two ways as described below: Take a look at: http://www.jguru.com/jguru/faq/view.jsp?EID=140877 for a solution using the Apache directive LocationMatch. Another solution is to use the mount directive. E.g., ApJServMount /intranet/servlet /intranet ApJServMount /intranet/jsp-bin /intranet The equivalent Jk directive is JkMount /intranet/servlet/* ajp12 JkMount /intranet/jsp-bin/* ajp12 In the archives, search for the subject "Servlet configuration" and read Jacob Kjome's informative postings. Whether you use LocationMatch or the appropriate Mount directive in your tomcat-apache.conf file, you *MUST* also modify your context's web.xml file and add an URL-PATTERN (E.g., url-pattern /jsp-bin/*/url-pattern ).

Urgent Help Required on TomCat Installation
Hello... I am using Linux Redhat 7.0 already intalled Jdk1.3. I somehow managed to override the Jdk1.1.7 which comes along with Redhat 7.0. I wanted Java Servlet Support so tried to install Apache JServ 1.1, but it was looking for Jdk1.1.7. So I then tried to install TomCat. Since Tomcat required Jaxp(Java XML Parser), Jakarta-Ant, I installed both of them successfully. After that I have been trying to execute the build.sh file of Tomcat, but it is giving me a warning that I need to use the deprecate option to compile the files. On observing closely the build.sh file, I found that it is referring to the build.xml file. I know deprecate is used to compile java files when some of the old methods of java are used. Since the class files are not created on compiling, the jar files are also not getting created. These jar files are probably used by Tomcat... Please let me know how to handle this case...

Tomcat Ready for Prime Time?
How robust is Tomcat? Can it really be used in a high stress production environment? I know that Apache is very robust? Is Tomcat on the same level? Have there been any stress tests done on Tomcat? Is there any independent performance data on Tomcat? We are considering the WebLogic enterprise application server. Can Tomcat be considered a true competitor of WebLogic? Thank you for your time and consideration.
