Servlet mapping with /
I'm trying to do something tricky with a servlet mapping for /. Basically, one machine will be serving a bunch of different hostnames from one IP address. For various reasons which I won't go into right now, it is an absolute impossibility to have separate IP addrs for these different machines, and also we can't configure them as virtual hosts in the server.xml file (trust me on this, it's an absolute impossibility). All the files that are served are in a few specific directories, like /statichtml, or /userhtml or whatever, which contain either static html or jsp pages. So here's what I did: I put this line in web.xml for the app: servlet-mapping servlet-name director /servlet-name url-pattern / /url-pattern /servlet-mapping I created a servlet called director.java, which would look at various parameters in the request, and then forwards it to the right place like this: RequestDispatcher rd = request.getRequestDispatcher(/staticpages/hello.html); rd.forward(request, response); or RequestDispatcher rd = request.getRequestDispatcher(/dynamic/hello.jsp); rd.forward(request, response); What happens is that when RequestDispatcher.forward() is called, it goes back through the mappings list, and sends the request straight back to director.java, which then looks at it and forwards it again, etc, in an endless loop. I understand what's going on, but is there a way to do it differently? I tried this also: RequestDispatcher rd = ServletContext.getNamedDispatcher(settings.corphtmlindex); but then I got this error: RequestDispatcher rd = ServletContext.getNamedDispatcher(/statichtml/hello.html); ^ director.java:159: non-static method getNamedDispatcher(java.lang.String) cannot be referenced from a static context I'm not sure what's going on here. One thought I had was this: in the mappings list, more specific mappings override less specific mappings, and / is the least specific mapping possible. Is there a way to put in mappings in web.xml to prevent the director servlet from being called? This seems like it would be a common thing to do under the MVC model, so there must be some solutions out there. Thanks

that it has the methods are required but ant is not picking up that

You have total control over where each JAR file is taken from, by
configuring the build.properties file. The quickest way to set this up
is to copy build.properties.sample to build.properties and then edit
it to suit. The properties that matter for this purpose are
servlet.home, servlet.lib, and servlet.jar.

getNamedDispatcher
Hi, I am trying to use ServletContext.getNamedDispatcher(String) to get a RequestDispatcher object in my servlet. The goal of this is to allow my controller servlet to hand off request processing to another servlet. What I have done is set up a default servlet-mapping in my web.xml file, so that all requests going to the server will be handled initially by a controller servlet, which will then decide which servlet should really handle the request. It will go through its logic and then come up with a string, which will be the real servlet which will handle the request. I'm trying to use getNamedDispatcher so that I can avoid the loop that would happen because of the default servlet-mapping. This seems like it should work. In my servlet's init method, I do this: this.context = getServletConfig().getServletContext(); This works. context is not null after this call, so it definitely gets a context. However, later when I do: RequestDispatcher rd = this.context.getNamedDispatcher(/static/index.html); rd comes back as null, and obviously rd.forward(request, response) is impossible. Any sugestions on this? How do I get a servlet to send something to a named servlet without going through the servlet-mappings again? Thanks

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
Questions on tomcat heap usage and garbage collection (avoiding OutOfMemoryError exceptions)
Platform: Intel PIII 797.499MHz, 256MB RAM Debian Woody GNU/Linux, kernel 2.2.19 Blackdown J2SDK 1.3.1 apache 1.3.19 tomcat 3.2.3 When using httperf[1] to stresstest JSPs on the above platform, I'm running into the OutOfMemoryError exception problem: http://www.jguru.com/faq/view.jsp?EID=64889 The solution suggested in the URL above, is to increase the heap size, but this is just pushing the problem ahead. The important thing for us, is that tomcat doesn't die. If this is a problem for high load sites, JSP technology would be unusable, and obviously it isn't. So what do others do? Possible alternatives: 1. increase the heap size to something astronomical, and just hope for the best? 2. tune apache/tomcat to restart more often, so that the max heap size aren't reached before the tomcat processes are restarted? 3. catch the exception? 4. use some kind of watchdog to restart tomcat? Question 3 raises more questions: 3a. What do you do when you catch the exception? There isn't much you _can_ do if you don't have any memory left. Maybe force a garbage collection and then re-run the request? 3b. Why do all the tomcat processes connected to apache processes die, if one of them gets an OutOfMemoryError exception Which brings us to question 2: tuning apache/tomcat: When reading the documentation, I thought that there was supposed to be a single tomcat process, serving all requests. However top reports a lot of tomcat processes, when I'm stresstesting the server, which leads me to belive that there is a separate tomcat process for each apache server process running. Is this correct? In any case; based on this assumption, I reduced the number of currently running apache processes from the default 150 to 20, with dramatically changed behaviour: instead of running with a 20% load, the machine was running at an 80%-90% load with less physical memory used (restarting processes is a lot of work). However, even with the high load, the end result was a lot more stable. Watching the tomcat processes in top, I could watch them grow up to around 82MB, before there suddenly was a lot of processes with around 19MB. It wasn't completely stable though. I set up httperf to do 1 million requests, before I left last night, and it only got to 51927 before tomcat died. I run httperf from a different machine (PIII 800MHz), using the command: httperf --server=no-video2 --port=80 --uri=/tps-sba/Welcome.jsp --rate 150 --num-conns=100 --num-calls=1 (--num-conns varies. I have mostly been using 1). The memory usage observed in top, also raises some questions related to my question 1: 1a. Why does tomcat processes always start at around 19MB, no matter what I've set the initial heap size to be? 1b. Why does the initial heap size seem to matter for my stability if the processes always start at 19MB? Is it all in my head?

Rotation of AccessLog
Hi, I have a problem with accesslog-rotation on Tomcat 4.0.1 (an previous TC 4). First I thought it would be the right behaviour that the log is rotated upon each restart. But now I took a look into the AccessLogValve (actually I wanted to implement the rotation that works even if the server runs) and if I read it right, then the Logrotation should work - but it doesn't.

I observe that repeated uploading of same file fails. ie., when I upload a file for second time(different content, same file name), in my servlet I am getting the old file only.

Re: Tomcat 4.0.1 not updating the webapp
I think it's a JDK bug. Since the WAR will be opened through a JAR URL, it is cached by the JDK until the JVM is terminated.

More experiments with changing the default (/) mapping
I have figured out a few things about how servlet-mapping and RequestDispatcher might work together. If I put in a servlet-mapping entry for /* (which will catch every request coming in to the server, which is something which I need to do), and I make the servlet which handles it look like this: RequestDispatcher rd = context.getNamedDispatcher(default); rd.forward(request, response); then it works for serving plain old static files. In toher words, http://localhost/foo/bar.html will get the bar.html from the /foo directory. This leaves me with two problems: First, if I understand correctly, servlets are not allowed to modify the HttpRequest object. This means that my director servlet can't change which director bar.html will be in. This is bad for me. Second, I can't get it to work at all for jsp pages. I would have thought that: RequestDispatcher rd = context.getNamedDispatcher(jsp); rd.forward(request, response); would work but it doesn't. I get an exception with a message org.apache.jasper.JasperException: No output directory: String index out of range: -1. I can't figure out why that is happening or what to do about it. So, any sugestions on a) changing the paths default and jsp will use to get their source pages from and b) how to get jsp to work? I also thought about doing this with filters, but the problem with filters is that they can only dispatch to servlets, not to jsp or html pages, which is what I need to do. Any sugestions would be most appreciated. Thanks

Hello. I have Apache and Tomcat configured to work with each other ( so I believe ). I have installed the following: Linux/Red Hat 7.1 Apache 1.3.19 (RPM) Tomcat 4 (RPM) mod_webapp 1 (RPM) tomcat4-webapps (RPM) On a Red Hat system with Apache 1.3.19 the default directory for html files are /var/www/html. On a Red Hat system with Tomcat 4 the default directory for JSP or servlets is /var/tomcat4/webapps/ROOT. Now, I am wondering when I create a JSP script in an html file where this file should go.

RE: Help ... Weird Problem
Depending upon which version of Tomcat you are using: 1. TC 3.2 and previous have a bug where a misconfiguration can cause the CPU load to spike and the page to never be served 2. Some versions don't handle the situation where you require authentication but set the constraints such that the login page also needs authentication (creating an endless loop) If you did a clean install then whatever might have been hacked, regarding Tomcat, will have been replaced. If the JVM was corrupt you would be getting crashes and not endless processing. Is Tomcat outputting any information to STDOUT/STDERR/its log files that would be relevant to this?

RE: Win2K IIS/Tomcat hangs
Hi Dan, I can't tell from the log, but I believe this is the symptom you would get if you accidentally used the isapi_redirect.dll from Tomcat 3.2.3 with Tomcat 3.3. To be safe, I would double check this. To shoot in the dark a little bit, what happens if Tomcat isn't running when you try this. Does it behave the same way or provide an error like it should? Maybe something else is on the receiving end. For fun, you could try switching to Ajp12 and see if something different occurs. In your current setup, does the Tomcat 3.3 log show any sign that it received anything from the Ajp13 worker?

Probably a typo below, but getRequestURL arrived with the

Hi Adam:
Somewhere in your compiler classpath, you've got an
older servlet.jar, as
the getRequestURL() method arrived in Servlet Spec 2.2. It may take a
little hunting to find it, especially if you're using an IDE
(I've run into
this problem with IBM VA-Java v3.5), but what you need to do
is get your
compiler to compile using the servlet.jar that you will find
in Tomcat's
/lib directory.
Good luck, don't get discouraged, it all eventually works
pretty well...

Hello,
I am currently running Tomcat 3.2.2 (I know, I've been meaning to

public void doPost(HttpServletRequest req, HttpServletResponse res)

I get a compilation error saying that the compiler cannot

However the following code compiles just fine:

}
am I missing something really obvious? All the documentation

RE: TC 4.0.1 - Catalina.start: LifecycleException
I believe you'll find that the BindException is occurring because Tomcat has not totally shutdown. On startup, it grabs the 2 server ports you specify in the server.xml. It appears that 4.0.1 uses threads to go out and kill those server ports on shutdown. My experience has been that it takes between 2 seconds or more to reliably assume those ports are now open again. If that is not the case, use netstat on the server and determine what is using that port(s). Perhaps there's another copy of tomcat running on those ports (especially if you're using the default install). -Original Message- From: Andrew Bruno [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 23, 2001 7:28 PM To: Tomcat-User (E-mail) Subject: TC 4.0.1 - Catalina.start: LifecycleException Hello tomcat-users, I am receiving this problem on a Windows 2000 Server SP2, which is trying to execute TOMCAT 4.0.1, using JDK 1.3.1_01 on port 8080.

I start and stop Tomcat 4.01 with startup.sh and shutdown.sh. 3. After this, I bring up http://my.domain.name:8080, and I see Tomcat 4.01 screen. 4. I shut down Tomcat, and bring up the Jboss/Tomcat 3.23 bundle. If I type http://my.domain.name:8080, I see the Tomat 3.23 screen. 5. I shut down Jboss/tomcat and type http://my.domain.name:8080, and I get can't connect to server or some such message. 6.

RE: Questions on tomcat heap usage and garbage collection (avoiding O utOfMemoryError exceptions)
I think the best thing you can do is to determine where the memory is going and fix your leaks. I say your leaks because in my experience, Tomcat doesn't leak memory and doesn't take a lot of memory for each connection. Randy -Original Message- From: Bang, Steinar [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 24, 2001 3:21 AM To: '[EMAIL PROTECTED]' Subject: Questions on tomcat heap usage and garbage collection (avoiding O utOfMemoryError exceptions) Platform: Intel PIII 797.499MHz, 256MB RAM Debian Woody GNU/Linux, kernel 2.2.19 Blackdown J2SDK 1.3.1 apache 1.3.19 tomcat 3.2.3 When using httperf[1] to stresstest JSPs on the above platform, I'm running into the OutOfMemoryError exception problem: http://www.jguru.com/faq/view.jsp?EID=64889 The solution suggested in the URL above, is to increase the heap size, but this is just pushing the problem ahead. The important thing for us, is that tomcat doesn't die. If this is a problem for high load sites, JSP technology would be unusable, and obviously it isn't. So what do others do? Possible alternatives: 1. increase the heap size to something astronomical, and just hope for the best? 2. tune apache/tomcat to restart more often, so that the max heap size aren't reached before the tomcat processes are restarted? 3. catch the exception? 4. use some kind of watchdog to restart tomcat? Question 3 raises more questions: 3a. What do you do when you catch the exception? There isn't much you _can_ do if you don't have any memory left. Maybe force a garbage collection and then re-run the request? 3b. Why do all the tomcat processes connected to apache processes die, if one of them gets an OutOfMemoryError exception Which brings us to question 2: tuning apache/tomcat: When reading the documentation, I thought that there was supposed to be a single tomcat process, serving all requests. However top reports a lot of tomcat processes, when I'm stresstesting the server, which leads me to belive that there is a separate tomcat process for each apache server process running. Is this correct? In any case; based on this assumption, I reduced the number of currently running apache processes from the default 150 to 20, with dramatically changed behaviour: instead of running with a 20% load, the machine was running at an 80%-90% load with less physical memory used (restarting processes is a lot of work). However, even with the high load, the end result was a lot more stable. Watching the tomcat processes in top, I could watch them grow up to around 82MB, before there suddenly was a lot of processes with around 19MB. It wasn't completely stable though. I set up httperf to do 1 million requests, before I left last night, and it only got to 51927 before tomcat died. I run httperf from a different machine (PIII 800MHz), using the command: httperf --server=no-video2 --port=80 --uri=/tps-sba/Welcome.jsp --rate 150 --num-conns=100 --num-calls=1 (--num-conns varies. I have mostly been using 1). The memory usage observed in top, also raises some questions related to my question 1: 1a. Why does tomcat processes always start at around 19MB, no matter what I've set the initial heap size to be? 1b. Why does the initial heap size seem to matter for my stability if the processes always start at 19MB? Is it all in my head?

Re: Multiple web.xml files?
That would be nice. In my app, when I add a Client I need to add a set of security constraints, mappings, etc. It would make maintenance MUCH easier if these could be modularized. This would also require more flexibility in the organization of the web.xml file. Ideally this functionality should have been a set of APIs which could be invoked programmatically (e.g. addSecurityConstraint()) so this could be done more dynamically without having to bounce the app to read a rigidly structured xml file.

I don't know what the right answer is, but I got my app to pick up the xerces parser by putting it in the jre lib\ext directory (e.g. F:\jdk1.3.1\jre\lib\ext).

AW: Questions on tomcat heap usage and garbage collection (avoiding OutOfMemoryError exceptions)
Some answers: - AFAIK the only 'memory leak' in tomcat is, that every JSP class stays in memory after it is loaded. - Find out or guess the amount of memory you need to hold all your classes - Find out or guess the amount of memory you need to all session data for all concurrent sessions. Keep in mind that the session will be alive for some time (default: 30 minutes after the last action in the action). This can be a reason for tomcat to bail out, if you use the wrong tool to do the stress test, where each request creates a new session (given a load of 10 requests per second you can have up to some 20.000 concurrent sessions). (Tomcat needs some memory for each session too) - The default setting can be to low if you have many JSP's and/or data in sessions - Try to find out if any of your software or any library that you use has memory leaks - If an OutOfMemoryError happens, all 'processes' of the vm die, because what you see are not processes, but threads that share the same memory. -Ursprüngliche Nachricht- Von: Bang, Steinar [mailto:[EMAIL PROTECTED]] Gesendet: Mittwoch, 24.

Possible alternatives: 1. increase the heap size to something astronomical, and just hope for the best? 2. tune apache/tomcat to restart more often, so that the max heap size aren't reached before the tomcat processes are restarted? 3. catch the exception? 4. use some kind of watchdog to restart tomcat?

Why do all the tomcat processes connected to apache processes die, if one of them gets an OutOfMemoryError exception Which brings us to question 2: tuning apache/tomcat: When reading the documentation, I thought that there was supposed to be a single tomcat process, serving all requests. However top reports a lot of tomcat processes, when I'm stresstesting the server, which leads me to belive that there is a separate tomcat process for each apache server process running. Is this correct? In any case; based on this assumption, I reduced the number of currently running apache processes from the default 150 to 20, with dramatically changed behaviour: instead of running with a 20% load, the machine was running at an 80%-90% load with less physical memory used (restarting processes is a lot of work). However, even with the high load, the end result was a lot more stable. Watching the tomcat processes in top, I could watch them grow up to around 82MB, before there suddenly was a lot of processes with around 19MB. It wasn't completely stable though. I set up httperf to do 1 million requests, before I left last night, and it only got to 51927 before tomcat died. I run httperf from a different machine (PIII 800MHz), using the command: httperf --server=no-video2 --port=80 --uri=/tps-sba/Welcome.jsp --rate 150 --num-conns=100 --num-calls=1 (--num-conns varies. I have mostly been using 1). The memory usage observed in top, also raises some questions related to my question 1: 1a.

Hi everyone;
I need help! i´m trying to set up my Tomcat 4..0.1 in such a way
than I can use a DataSource in my aplicaction called FtcApp.

try {
ctx = new InitialContext();
cpds = (DataSource)ctx.lookup(/jdbc/FtcAppDb);

I tried to do this using the manager application and found that whenever the reload command is issued from a servlet in the target app (the one to be reloaded) it causes the manager and target apps to hang: 2001-10-22 16:32:34 StandardWrapper[/AGCW:Manager]: Loading container servlet Manager 2001-10-22 16:32:34 Manager: init 2001-10-22 16:32:34 Manager: init: Associated with Deployer 'localhost' 2001-10-22 16:32:34 Manager: restart: Reloading web application at '/AGCW' 2001-10-22 16:32:34 StandardContext[/AGCW]: Reloading this Context has started 2001-10-22 16:32:34 StandardWrapper[/AGCW:Manager]: Waiting for 1 instance(s) to be deallocated the last entry indicates the hanging servlet.

Re: getNamedDispatcher
Doing this trick with servlet mappings is pretty much doomed to failure, as you have discovered, because servlet mappings are applied to the lookups of request dispatchers as well. I suggest you look at using Filters (from the servlet 2.3 API) instead. For instance, you can have a Filter that is mapped to /* (and therefore sees every single request), without disrupting what servlets are mapped to the various paths. In the Filter, you can make the choice to just pass the request on, or use a request dispatcher to redirect it somewhere else.

The goal of this is to allow my controller servlet to hand off request processing to another servlet. What I have done is set up a default servlet-mapping in my web.xml file, so that all requests going to the server will be handled initially by a controller servlet, which will then decide which servlet should really handle the request. It will go through its logic and then come up with a string, which will be the real servlet which will handle the request. I'm trying to use getNamedDispatcher so that I can avoid the loop that would happen because of the default servlet-mapping. This seems like it should work. In my servlet's init method, I do this: this.context = getServletConfig().getServletContext(); This works. context is not null after this call, so it definitely gets a context. However, later when I do: RequestDispatcher rd = this.context.getNamedDispatcher(/static/index.html); rd comes back as null, and obviously rd.forward(request, response) is impossible. Any sugestions on this? How do I get a servlet to send something to a named servlet without going through the servlet-mappings again? Thanks

Re: Questions on tomcat heap usage and garbage collection (avoidingO utOfMemoryError exceptions)
The most important task in a situation like this is to find out why memory is being consumed in the first place. Generally, this is caused by one of the following types of factors: * Creating lots and lots of session attributes in your applications (which causes the objects to stay allocated until the session times out or is invalidated) * Creating a new session on every request from your stress test tool, which causes a new session object to be created each time. The latter case is pretty insidious for doing stress testings, because JSP pages are session-aware by default (unless you tell them not to). This behavior is not typical of real users, howevever, because they will be returning the same session id (and therefore accessing the same session) throughout their interaction with the server. You should investigate whether httperf (or other tool) can let you remember the session id that was assigned in the first place and then reuse it on the subsequent requests, and/or whether your test JSP page can temporarily be set to not use sessions so that this doesn't happen.

Warp connector hangs on images (W2K)
I have had a consistent problem with images being served via the warp connector in trying to install TC4.0. I originally tried to piggy back this on what seemed to be the same problem in another thread -- sorry, I guess that was poor etiquette. I don't do these lists much and didn't see that in the suggestions for proper posting. Here's the short of it:after installing the binary download of 4.0.1 on Apache 1.3.20, I first attempt the examples context on port 8080, which works fine. I then attempt it on :80. The text of the page displays fine but the images never download. The browser displays the message Downloading picture ... code.gif. If I disable image display in my browser prefs, everything screams along. I confirm that the examples are actually running by going to the session servlet example and see that it's tracking me correctly, which it is. The further confusing point is that my co-worker has no problem using the same setup. I also had everything working fine under TC3.2. I've tried using the nightly snapshots (although there are enough quirks to compiling them that I'm not convinced I got it right). Does anyone have any suggestions? Geoff Howard
RE: Tomcat 3.3 classpath
The :staticClasspath portion of tomcat.bat is executed only for the env and jspc actions, but not for start and the others. They use just: set CLASSPATH=%TOMCAT_INSTALL%\lib\tomcat.jar. However, adding classes via the CLASSPATH is more often than not, a source of problems. A lot depends on how those classes will be used and what other classes need to be visible to those classes. Here are the recommended methods for adding class files in order of preference (assuming you don't want to put them in a webapp's WEB-INF/classes directory): 1) Create a classes directory under lib/container, lib/common, or lib/apps as desired, and place the classes under there. The classes directory will be included in the corresponding classloader. This method hasn't made it into the documentation yet. 2) Specify your classpath entry in one of the following Java System properties: org.apache.tomcat.common.classpath - Common classloader org.apache.tomcat.apps.classpath- Apps classloader. On NT and Win2k, you can use the TOMCAT_OPTS environment variable to accomplish this, i.e. set TOMCAT_OPTS=-Dorg.apache.tomcat.apps.classpath=d:\ This won't work on Win98 because it doesn't like the '=' inside the environment variable value. You will need to add the -D... to the tomcat.bat command that executes java. 3) Modify the tomcat.bat to set the CLASSPATH differently. Hope this helps.

The class used to access the uploaded file is com.oreilly.servlet.MultipartRequest [...] I use TC-4.0 + cos.jar(cos-23Jan2001.zip from www.servlets.com) to test it, I upload zTest.jar twice(same name, different content), in Servlet-side, I get the new zTest.jar in the 2nd time.

RE: Precompiled jsp's
Create servlet mappings from the desired URL (i.e. /directory/file.jsp) to the generated class names. If you are using JSPC to precompile the files, pass it the --webxml flag and it will generate the relevant portion of the web.xml for you.

File Download - CSV question ****
I wrote an application that for Tomcat 3.2 running on window. In the HTML the is a reference ( A HREF=/filname.csv ) to the filename. When I run this on windows I get a popup save as selection box. When I run this on Tomcat4.0 on Unix it no longer gives me the selection box but instead displays the data on the screen. Is this a difference between TC32 adn TC40 or Unix / Windows. Is this configurable. Thanks in advance.
RE: WAR auto-deploy context permissions
Carl: I assume you are using a unix variant. You could chown all of the new files in the webapps directory... You could add this to the startup script. Brad Moreland -Original Message- From: Carl Bacher [mailto:[EMAIL PROTECTED]] Sent: Friday, October 19, 2001 2:22 PM To: [EMAIL PROTECTED] Subject: WAR auto-deploy context permissions I'm trying to create contexts for the developers at my site by simply posting the war file, eg. mycontext.war, in the webapps directory and restarting tomcat, which creates and automatically extracts it to a context directory named mycontext. It works fine, but the permissions on the directories and files are all only writeable / executable to the owner, which is root (presumably because tomcat was started as root). They are also all in the root group. Is there a way to configure tomcat such that, when the war file is extracted, the expanded context directory hierarchy has the permissions it was either jarred up with, or uses an owner/group other than root so that the permissions can be updated by someone in that group? I'm currently just specifying the context in the server.xml file, creating the directory in webapps and extracting the war file manually, which works just fine.

problems on integration Apache 1.3 and tomcat 4.0 under NT environment
Hi, there, Here is the problem: I succeed install Apache 1.3 and tomcat 4.0. it works fine independently. Now I am trying to integrate them together as following: 1) downloaded mod_webapp...for win32 and unzipped 2) copied mod_webapp.so and libaper.dll to the module directory in Apache 3) edit configuration file of Apache and problems appear here: A. add a line of : LoadModule webapp_module modules/mod_webapp.so AddModule webapp_module mod_webapp.c B. run the program of test configuration and it returns: Cannot add module via name 'mod_webapp.c': not in list of loaded modules C. If I comments out the line AddModule mod_webapp.c and run test configuration, it returns Syntax OK. Q: Can we leave this line commenting out? If no, what to do? D. with the above item C (commenting out), I added the following: WebAppConnection warpConnection warp localhost:8008 webAppDeploy examples warpConnection /examples/ and run the test configuration, it returns: Invalid virtual host name Q: I did not edit virtual host name, why it says invalid? How to solve this problem? E. For win32, do we need mod_jserv file in the modules directory of Apache? If yes, where can I find a built mod_jserv file? is the file libaper.dll a equivalent of mod_jserv? Thank you very much for help. Bin

log-off event bug in JDK 1.3.1
Refering to the following:
Notice for JDK 1.3 users: There is a known problem
http://developer.java.sun.com/developer/bugParade/bugs/4323062.html in JDK
1.3 that affects Java applications being run as Windows NT services. The bug
causes the service to terminate when the currently logged in user logs out.
The simplest way to work around this problem is to use JDK 1.2. If your
application requires JDK 1.3 features then you may want to look into
javaserv http://www.kcmultimedia.com/javaserv/ or JavaService
http://www.alexandriasc.com/software/JavaService/. Users have reported
success with both of these packages but there may be others that work as
well.
I have written my own NT Service program that works fine with JDK1.3.1, and
does not suffer from the logout bug. The solution is to disable the windows
logoff event in the Windows ConsoleControlHandler.
E.g.
BOOL WINAPI ConsoleControlHandler(DWORD dwCtrlType)
{
switch (dwCtrlType)
{
case CTRL_C_EVENT:
case CTRL_BREAK_EVENT:
case CTRL_CLOSE_EVENT:
case CTRL_SHUTDOWN_EVENT:
case CTRL_LOGOFF_EVENT:
return TRUE;
}
// Let parent handler (the VM) take care of anything else.
return FALSE;
}

tomcat session problem
Hi there, I am using jakarta-tomcat - 3.2.3 server to run my project. I am finding that session tracking, when more than one browser window is opened at one time, doesn't come out to be correct. I am using its inbuilt session object and the cookies are enabled in my browser. When more than one sessions are running then the page presented is unpredictable.Sometimes correct page displays and sometimes totally diferent page gets displayed. It works great except if I have 2 browsers sessions up - then it gets confused and losses track of which is the current session. Are there any issues with the Tomcat server regarding session tracking? Thanks in advance, -Rinku
Re: Precompiled jsp's
You should be putting your uncompiled jsp's in your context's root directory (webapps/your-context/your.jsp). Tomcat will do the compiling for you. When you access it via http://host:port/your-context/your.jsp, Tomcat will compile it for you and put the class file (and source file) in the 'work' directory, probably tomcat/work/your-context. If it's already been compiled and the timestamp on the compiled version is more recent than the timestamp on your.jsp file, it will use the compiled version it already has.

[ANNOUNCEMENT] Tomcat 3.3 RPM Fixed
A little problem was discovered by Nicolas Mailhot, in the tomcat 3.3, java part, with an incorrect tomcat init script which wasn't used the new 'nobody' work mode. Now tomcat run as nobody by default for security purposes. The RPM has been updated to -2 release and the old one removed : http://www.apache.org/dist/jakarta/jakarta-tomcat/release/v3.3/rpms/ tomcat-3.3-2.src.rpm tomcat-3.3-2.noarch.rpm tomcat-webapps-3.3-2.noarch.rpm tomcat-manual-3.3-2.noarch.rpm For those of you who has allready installed the tomcat and want to let it in place (for example in production system), the fix is easy. Replace the init script (/etc/rc.d/init.d/tomcat) by the one attached and make the /var/spool/tomcat and /var/log/tomcat dirs must be owned by nobody/nobody: chown -R nobody:nobody /var/log/tomcat chown -R nobody:nobody /var/spool/tomcat Sorry for the disturbance and a big thanks to Nicolas for his quick discovery and report. - Henri Gomez ___[_] EMAIL : [EMAIL PROTECTED](. .)
