Re: definitive answer on JSPC?
I'm working off 4.1.18 and it appears it has been the same all through 4.x, even through the jasper rewrite of 4.1.4. I understand this is the problem I'm facing - I was hoping for a cleaner solution than to run javac individually for the 200 or so JSP files. That is what I'll do if needed, so I'd appreciate the work you've done. I'll check out the ant list of any mention of it - I didn't think of that originally but it makes sense. Still, I'd hope one of the jasper developers might shed some light on the other points? Cheers, Brett Chris McNeilly wrote: Don't know how 'definitive' this is, but here are my experiences. Its a bug/feature of jspc, depending on how you look at it. As it loads all relevant jsp files into memory to compile, it only used the file name, not the full path, making the compiler see all your index.jsps as the same, which causes the error. I believe there is a fix for this out there somewhere. I found a pointer to the fix on an Ant message board. I also added functionality to Ant that compiles each jsp in its own memory space, thus working around the bug. Let me know if you can't find the fix (it might already be part of the next Tomcat build) and want to dork around with my effort. The work I did on it was back about 3 months ago, so I don't know what has been done recently. Chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
definitive answer on JSPC?
Hi, I'm looking for a definitive answer about JSPC in Tomcat 4.1 and precompilation. Searching the archives hasn't yielded answers to the questions I've been curious about. It'd be great to get definitive answers for the archive, and perhaps a FAQ as it is not covered in either tomcat-user, the doco, or JGuru. Background: In TC3.2.4 I currently precompile all JSPs using the ant jspc task and the TC3.2 jasper/webserver jars. I then munged the generated java files into the format required by TC3.2.4 and compiled them, then renamed them again to match. A little weird, but it worked since it used a flat directory structure, formatting the filenames with_002f etc. I dropped this into /WEB-INF/classes/precompiled_jsp and symlinked it from work/localhost_8080%2Fapps. The reason this was necessary was that the server choked under the load trying to compile the JSPs. There seemed to be no deadlocking so it would spawn numerous javacs and start swapping, and you get the picture :) With TC4.1 I can't take this approach because of the (albeit nicer) directory approach. However, because of duplicate names and the same package being used, I will need to compile each java file individually, complicating the build process considerably. BTW, I'm aware of ?jsp_precompile=1 and it's not suitable. Here are my questions regarding jspc from ant/cmd line: 1) is the definitive way to do it supposed to be the web.xml include method? If so, shouldn't JSP take a web.xml input and output a processed one? Regardless, doesn't this have negative side effects, like not then being able to edit the JSPs to make changes? (note that while we precompile, we may need to change some, and filtering them out would be a fair nuisance). 2) is there a way to do what I am looking for above, generating classes for all JSPs that are not fragments (for static include) which can be placed in the work dir? Does it have to have the same layout as the server to work? 3) what is the reason for the current layout and differences between cmd line and server compilation? ie. different dirs but same package. My desired requirements for JSPC to work would be: 1) both JSPC and server generate the same java files to the same locations. 2) javac can be executed on the base directory on **/*.java, and the resulting classes dropped into the work directory. They would be used as long as their timestamps were newer than the jsp in question. To achieve this, I'd suggest this: 1) package name is org.apache.jsp.PATH.TO.FILE (substituting/eliminating special characters - eg WEB-INF - WEBINF) 2) class remains myJsp_jsp.java 3) have TC not only look under work but /WEB-INF/classes to avoid the symlink (ie if I specified my package as precompiled_jsp I'd get the result as I have for 3.2.4). And a final question: how likely am I to encounter the problems had with 3.2.4 if I upgrade to 4.1? I believe the jasper2 compiler is designed to be much more effecient - will it avoid generating the java files more than once and hence compiling them more than once, instead synchronizing on the operation? (this is effectively enough, although precompilation would still be even faster). I'd appreciate any responses regarding this, and apologise for the verbosity level of the email! :) Thanks, Brett - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

While this is fair enough, its also fair that there's a level of frustration with people who clearly haven't read the docs. There's a good example in there of how to set up Tomcat and your first webapp using ant and giving example code. Why repeat it over and over again on this list? I certainly remember when I first used Tomcat last year. I read install guide, got it running, read the docs from there - ALL OF THEM. Funny how after that I didn't feel much need to post to the list. You may not realize that CATALINA_HOME, etc. are variables covering certain urls. I remember when I did not as well. Just to make sure you don't confuse the original poster... what does CATALINA_HOME have to do with URLs? On the context stuff, the only real way to understand this, because no one will really tell you or give you adequate examples, is to go to the Tomcat code and see how the code is written. After asking and trying to get help many times, that is what I did. It takes a bit, but then you have a solid understanding of the Tomcat architecture. That's a rather inflammatory and incorrect statement. The documentation is just fine - and if its not good enough for you, you are welcome to amend it. The example I gave above explains all this - going to the code isn't going to be very helpful if you aren't even at the level of starting the server and deploying a webapp. Anyway... Mondays suck.

Re: VM size increases.
You are really going to have to look at this more closely before pointing fingers :) 2 days with that many hits is actually a slow leak unless you have a lot of RAM. Still, a leak. The leak could be in the JDBC driver, your code, or any other library (including Tomcat). Have you upgraded to the latest Tomcat (3.2.4) in that line? Your next step will be to use a profiling tool (JProbe, optimize it, etc) to find where the leak is. For instance, you may be using an infrequent circular reference in your code that causes it never to be release in garbage collection. You should have your code modularised enough to be able to beat it outside the servlet container with something like JUnitPerf to see if you have any such problems in certain modules (this is often a little idealistic :) Hope this helps, Brett Rajesh Mishra wrote: I'm using Tomcat3.2 and SQL server2000.

Cygwin fix, but problems: AJP from connectors-4.0.2
Hi, I've been trying to set up apache-2.0 and ajp13, Tomcat 4.0.3 under Cygwin. I'm using the jakarta-tomcat-connectors-4.0.2-src.tar.gz download. I'm using the native branch under jk, as native2 won't work with Cygwin - something to ask the ant guys I guess, the so task fails. I had issues getting shared objects to work - I know cygwin is still toughing it out a bit with libtool, especially because of the autoconf2.13/2.52 differences, so I built it static. After a couple of small changes (I'll contribute them at the end), it compiled fine and I rebuilt apache with mod_jk.c built in. httpd -l shows it there. I've used a working workers.properties configuration from my last setup, and apache + mod_jk 1.2 starts up ok, but when I try to access something via ajp I get a 500. The error_log reveals that it can't factory the worker ajp13*ajp13. I've started to look into the C code and am not sure why the property worker.brick.type=ajp13 gets converted to ajp13*ajp13 - is this a known bug? Ok, here are the fixes for at least a static Cygwin build: is there a better way to contribute them? (diffs?) jk/common/jk_global.h: The #ifndef _OSD_POSIX needs to change to #if !defined( _OSD_POSIX ) !defined( CYGWIN ) in the include section - that sys header is not there and not needed jk/buildconf.sh: automake chokes on the -i, but I'm nt sure why yet. Removing it works ok. jk/configure.in: AC_PROG_CC needs to be before the LIBTOOL defs. Works for cygwin - don't know if it would break anything else. When finished building, the config.m4 put into the apache build directory is missing the subdirectory name of the static library, so it is unable to find it without editing it. Hope this helps!

UnsatisfiedLinkError means JVM can't find shared library. You need to add shared library path to environment variable. If you use solaris or linux, then you should add following statement in your tomcat.sh. LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH export LD_LIBRARY_PATH if you use HP-UX, then SHLIB_PATH=$ORACLE_HOME/lib:$SHLIB_PATH export SHLIB_PATH if you use Windows, then you should add following to tomcat.bat. set PATH=%ORACLE_HOME%\lib;%PATH% then it will be able to find shared library. regards, Watanabe. -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED] -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED] -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED] -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED] -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED] -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
mod_proxy and getRemoteAddr()
Hi, I configured mod_proxy as per the Tomcat 4.0 doco. All working fine, but I've recently tried calling getRemoteAddr() and find I can't get anything but 127.0.0.1. If I bypass mod_proxy (go straight to tomcat) it works ok, reporting my IP address. Does anyone know how I can get the remote address if I am using mod_proxy? I tried mod_webapp and had too many problems - has that matured since Tomcat-4.0? What about using AJP13?

RE: Bringing up tomcat, reliably.
Thank you for your reply. I have tried HelloWorldExample and it is ok. But I wonder how the path is set. When I request http://apachehost/examples/servlets or http://apahcehost/examples/servlets/index.html, I expect it will return file d:/tomcat/webapps/examples/servlets/index.html in the tomcat server, because I have the following line in the config file: Alias /examples d:/tomcat/webapps/examples But the error log return : File does not exist: d:/tomcat/webapps/examples/servlets/index.html Ada.

TC4.0.1 - 500 error-page not working
Hi, I've implemented a JSP page for handling 500 errors, but its not working. A similar page works fine for 404 errors coming from Tomcat. The error in question is a NullPointerException, but this shouldn't matter. From web.xml: error-page error-code500/error-code location/system/error_docs/server.jsp/location /error-page error-page error-code404/error-code location/system/error_docs/filenotfound.jsp/location /error-page The jsp's use templates. Is it just the case 500's don't work with JSP's? Searching the mail archive for a similar topic only revealed information about how to do it from the servlet spec., which is what I used to achieve this. Thanks, Brett
mod_webapp and datasource failure
Hi, I have looked into the mail archives and seen others with the same problem: when using WARP, datasources don't work as they get deployed as null. The solutions mentioned were: 1) set ServerName to an IP address and the same in both that and server.xml - didn't work, tried various combinations 2) use nightly builds of mod_webapp - doesn't compile with a stock tomcat 4.0.1 ditribution when it gets to warp.jar. It certainly seems to be attempting to deploy the webapp twice - it logs the first time successfully in localhost_log_..., and fails when you start apache and it logs that to cataline_log_... using the loggers from the example server.xml. Is there any solution to this, other than using a snapshot build of tomcat? Is my best alternative to use a snapshot, the release AJP connector (haven't tried it), or try and tunnel requests to a HTTP connector? Thanks, Brett
WARP plugin status at 4.0.1 - README on server
Hi, Looking at the README on the server where I downloaded the WARP plugin yesterday, it said there were issues about starting/stopping tomcat and apache recognising this, that would be corrected in the final release. I'm assuming this is the 4.0 final release, so I'm wondering what the status is. I've noticed that if you start tomcat after apache, you must restart apache to recognise that the container is started. Are there any other situations like this? It appears restarting tomcat without restarting tomcat is fine. We would like to have monitors that automatically restart the server if it is hung, and want to be careful that it doesn't get in a condition where it might start apache without tomcat running. Regards, Brett
Re: automatic shutdown from servlet.init() that is load-on-startup
I realise this isn't very well-behaved, but any others will probably be
dealing with the same problems. At this point in time there is only one
web application.
Perhaps there is another solution - eg send an email on failure and get
an administrator to check in on the problem.
Cheers,
Brett
