Re: session timeout not working anymore :(
I admit not not looking at this in detail. But the lack or a 'return;'
statement after the jsp:forward is a major red flag.

Hi, I'm running out of options -- but is there a problem with
getSession(false)?
Sigh. We used to have a piece of code included in our jsp's like so:
header-inc
% if (request.getSession(false) == null) { %
jsp:forward page=logout.jsp?TIMEOUT=60 /jsp:forward
% } %
jsp:useBean id=user scope=session class=webapps.common.User/
header-inc
and that was included in our files like so. That used to work.. but
now when I have struts-html and struts-bean.. it always fails.
Is there something wrong with getSession(false) now?
The stack doesn't seem to include the struts generated servlets.. so
I'm really puzzled!!
Any help will be much appreciated even if it's only to say.. it's not
struts :)
I'm running Tomcat 4.18 on Windows XP.
Thanks.

Setting up Tomcat to run JSP pages...
Hi, I'm new to Tomcat, using 4.1, and have set up Tomcat to run with Apache...that works. However my question is how can I put a JSP page or servlet in my site directory and have Tomcat recognize it and render it even though it's in a folder outside of web-inf? I'm using windowsXP right now.

Actually, further testing reveals that the problem occurs with the statement. If an exception occurs while the statement is being prepared, then an exception is thrown. However, it would appear that this exception is thrown after a cursor is opened (internally) and that cursor is never closed. A call to close on the statement in turn throws a NPE because a value was never assigned to it. Thus, I'm left with an open cursor on an object that I can't reach. Can anyone else validate this?

Re: LE vs. Full
On Tue, 2003-02-04 at 23:21, Rick Fincher wrote: Type java -version from the command line where you are running the RPM to be sure you are getting 1.4.1. RH 8.0 ships with a JDK 1.3.1. JAVA_HOME doesn't have any effect on the shell, only on Tomcat. You have to set your path so that the shell finds 1.4.1 before 1.3.1, so it can find all the 1.4.1 stuff it is looking for for the dependency checks. Since a Tomcat install doesn't install any libraries or do anything except upack the files you might be able to roll your own simple RPM to install it. Or just write a script that unpacks Tomcat with the assumption that 1.4.1 is already installed. I looked at it some more. This is what the tomcat rpm requires: # rpm -q -p tomcat4-4.1.18-le.1jpp.noarch.rpm -R jaxp_parser_impl xml-commons-apis /bin/sh /bin/sh /bin/sh rpmlib(PayloadFilesHavePrefix) = 4.0-1 rpmlib(CompressedFileNames) = 3.0.4-1 /bin/sh And this is what the j2sdk rpm provides: # rpm -q --provides j2sdk-1.4.1-fcs j2sdk = 2000:1.4.1-fcs It seems like Sun's Java rpm doesn't indicate that it provides jaxp_parser_impl or xml-commons-apis, so the Tomcat rpm doesn't work. I tried it like this: # rpm --install -v --nodeps tomcat4-4.1.18-le.1jpp.noarch.rpm Preparing packages for installation... tomcat4-4.1.18-le.1jpp couldn't find /usr/share/java/jaxp_parser_impl.jar make sure to have a JAXP_PARSER RPM installed and make a symlink : ln -s /usr/share/java/jaxp_parser.jar /var/tomcat4/common/endorsed/ couldn't find /usr/share/java/xml-commons-apis.jar make sure to have xml-commons-apis RPM installed and make a symlink : ln -s /usr/share/java/xml-commons-apis.jar /var/tomcat4/common/endorsed/ which forces it to install without checking dependencies. It complains that it wants a jaxp_parser_impl.jar and a xml-commons-apis.jar somewhere. However, I disregarded those complaints from it, and ran it and it works fine. So my suggestion is this: Maybe the tomcat-4-4.1.18-le.rpm should check for j2sdk-1.4 instead of looking for jaxp_parser and xml-commons? If it worked that way, I could just do rpm install of the Sun j2sdk, and then rpm install tomcat-le, and it would be done. Otherwise, I will just use --nodeps, but that is somewhat contrary to the idea of an rpm, right? Thanks! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I'd like to get my hands on some docs on the area especially some examples of JkUriSet. Any pointing to the right direction is much appreciated (except for jakarta's jk2 doc page).

Re: DBCP+TOMCAT 3.2.4 (-4.1.x WORKED OK)
Please, how should I interpret the exception message header below:
javax.naming.NoInitialContextException: Need to specify class name in
environment or system property, or as an applet parameter, or in an
application resource file: java.naming.factory.initial
I'm using jdk1.4.1 (SUN) and tomcat 3.2.4.

RE: singleton creation (ot)
Hmm... nice links!
The first one said about a proposal of solving this problem through
the use of volatile keyword... this was implemented in jdk 1.4? It
seems that site is older than this release...
I'm not sure yet of how I will do it... I would not like to
synchronize the entire method because it'll probably be called million
of times in my app

I was wondering... this code is valid to avoid excessive use of
synchronized code? I think so, but we never know :-)
This is the default getInstance() method of a singleton (simplified):
public Object getInstance()
{
if (INSTANCE == null)
{
synchronized (this)
{
if (INSTANCE == null)
{
INSTANCE = this.getClass().newInstance();
}

}
return INSTANCE;

RE: Why won't anyone help me out??
I was not talking to you, Steve. I actually shouldn't even be replying now, but I see you've changed your email address which is how this got past my filter, and I would like to try and help (I really would), but I honestly don't have the time. Even if I did, I am primarily a systems administrator, not a developer, so I doubt I could answer your Java programming questions. I've tried and tried and tried to help you in the past, as have other people, and it just isn't an effective, efficient use of my time. My suggestion: buy a book (like the two O'Reilly books dealing with servlets and JSPs) and subscribe to a java-user list. You'll probably get a lot more response for your beginning Java questions there than you will here. I'm not being arrogant or mighty when I say that (I'm actually a very humble person but with an extremely direct and blunt demeanor), I am simply making an observation. You've been posting here for months (at least 8) and are still having problems, the most recent of which are not related to Tomcat. I think that may be a good indicator for you that this list is not the list that can help you, and is not a list where you can get help the quickest. I'm sure there are other lists out there that can give you the full and complete answer you are looking for, and do so in the timeframe you demand.

Tomcat 3.2.1, IIS 5 and AJPv12
I am currently running the above for my servlet application. (tomcat 3.2.1, IIS 5 and AJPv12) Cant get more than 250 syncronous users with this setup!! Is 250 users to much for this system. What can i improve to get more than this My problem is that I am getting a page not found error(405.htm i think) when I push the number of simultaneous threads up to 250. I can set my server up to a limit on 200 threads (get 403-9.htm) and dont get the previous error page. When I look in my ISAPI.log file fore errors, i get this: jk_ajp12_worker.c : ajpv12_handle_response, error writing back to server jk_isapi_plugin.c : jk_ws_service_t::write, writeclient failed (basically lots of these ajp12 worker and isapi plugin error messages) No other errors noted, except instead of JSP page, I get a default error page as mentioned previously. I am running a default connection pool through my tomcat configuration!! What is likely to be the problem!! Is 250 threads to hardcore for this setup! Is it my memory or server (dual-700 x86 nt) Has anybody had this setup over 250 threads?? Any ideas on how to test this further to find out where the bottleneck is, I would most apprechiate.

RE: Why won't anyone help me out??
Steve, if you're going to post to a list, please get acquainted with the concept of threaded discussions. My first reply in this thread was not to you, but to the person known as jsp. His reply of live long and prosper was directed to me, to my reponse. You can see this because he included my post in his (her?) reply. You will have a LOT LESS frustration if you take some time and become acquainted with the concept of threaded discussions and replies. Just because you start a topic does not mean every reply in that topic is directed to you. Just like a conversation in the real world, an email/list discussion has the ability to go off on tangents. You'll be doing yourself a big favor and help make your time MUCH MORE effective and make more progress getting a solution as soon as you understand that 1) not everyone hates you, 2) not everyone is directing their replies directly to you even though you started the topic, and 3) the people on this list would love to help you and have tried to so significantly in the past but, like you, are getting frustrated. A lot of us are extremely busy, and we like to see our time being used effectively and efficiently (we can help more people that way), and we get annoyed and irritated when people submit posts that have critical or demanding tone, implied or explicit insults and criticisms, and unreasonable demands, especially if they do so repeatedly in spite of polite requests to stop. Remember, this list is free. Nobody is required to be here, and nobody is required to help anyone else. Getting adamant and abusive about not getting help isn't going to help you, and isn't going to get you any progress. Call me arrogant if you want, it's simply not the case. I am trying to explain to you how to get the most out of this list and help decrease your frustration level. As I'm sure others do, I just want my time to be spent as effectively as possible...time is too valuable.

Rf Subject: tomcat's serlvet container and http From: rf rufoo2001 () yahoo ! com Date: 2003-02-03 1:59:58 Hello I have some questions related to how tomcat's servlet container handles some HTTP/1.1 issues. Understanding these, I think, would be beneficial in improving the performance of my web-application. Here they go: 1. How can my servlet respond with transfer encoding as chunked? When is my serlvet's OutputStream committed? I dont have all my data ready, I want send it out in chunks - how do I do it? 2. How can I use 100 Continue response header? This is usually used on slow links, but I want to use it when my processing is slow. My servlet is doing some processing and is going to take some more time - how do I inform this to my client? Can I just set HttpServletResponse.setStatus (SC_CONTINUE)? (Can this response be sent more than once?) If this method is not right for the scenario, what is the recommended way of informing the client to patiently wait for some more time? 3. The response in HTTP/1.1 can have footers in addition to headers, how do I set a footer? I guess we cannot use HttpServletResponse.setHeader because the servlet spec says setting a header has no effect if the response is already committed. 4. Persistant connections - is this configurable in a tomcat? It might be the case that this is not something a user should bother about, the servlet container will take care of it. What does tomcat do? Whenever needed, I want to recommend my client to use a persistant connection for following requests. Can I do it? An IE question: what factors determine that IE should use a persistant connection? 5. If-modified-since header. There is a getLastModified method in the servlet interface, this returns a long(for date). I guess I should implement this method for tomcat to respect the if-modified-since header. I recently implemented a caching filter, which intelligently uses the default servlet to serve cached static content. But since the former method is simple and more effective, I would like to know when IE uses this header. Since this header is optional, how do I recommend IE to use it?

Re: DBCP+TOMCAT 3.2.4 - javax.naming.NoInitialContextException
It appears that it needs more than an empty constructor in
InitialContext():
try{
Context initCtx = new InitialContext();
Context envCtx = (Context)initCtx.lookup(java:comp/env/);
this.ds = (DataSource)envCtx.lookup(/jdbc/ngincaredb);
}
catch(NamingException e){
logger.fatal(datasource error, e);
}
So, the solution maybe doing something like this:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, );
Context initCtx = new InitialContext(env);
But the obvious question (and unknown for me) is what should be the
tomcat 3.2.4 default JNDI factory to put in
Context.INITIAL_CONTEXT_FACTORY attribute?? And why in tomcat 4.1.x it's
enough put a empty InitialContext()??
I don't find docs for tomcat 3.2.x about the resources/jndi...

Pedro Salazar.

Re: Does TC 4.1.18 actually reuse tag handler instances?
having done profiling in OptimizeIt with tomcat +
JSTL, I can say with confidence it does reuse the
tags. How do I know?
I've ran profiles with jasper1 and jasper2. With
jasper 1 if I have say 200 tags in a page, it makes
200 tag objects. With jasper2, it makes one of each
tag. So if have say 20 c:if tags in a page, there's
only one.
if you look at the generated source in the working
folder, you'll see this. You can easily verify this by
running 4.0.3 with jasper1 and compare the source
generated. It looks like you're using custom tags
which you've written yourself. Whether your tags are
written to take advantage of tag pooling is another
topic.

On the first iteration, the setter method is called

I happen to know that a similar test case run under

Installed Tomcat 4.1.18 for WinNT recently and have come across something that isn't covered in the documentation. When trying to get multiple instances of Tomcat running (in Windows), it also needs a 'temp' directory in $CATALINA_BASE as well as the 'webapps', 'conf', etc... Don't know if anyone here could add a note to the official documentation...

Apache JK problem
Hi, I'm having problems with connecting Apache httpd 1.3.26 to Tomcat 4.1.18 using mod_jk. My operating system is Solaris 8. The error message I get in the apache httpd error log is this: [Wed Feb 5 13:57:19 2003] [error] (2)No such file or directory: Error while opening the workers, jk will not work I have done the following: * Downloaded the binary distribution of mod_jk.so for apache without ssl, and put it in the libexec-catalog under httpd. * Enabled the auto config generation in server.xml to generate the $CATALINA_HOME/conf/auto/mod_jk.conf * included the auto-generated mod_jk.conf i my httpd.conf * Enabled the Ajp 13 listener in server.xml * Created the $CATALINA_HOME/conf/jk/workers.properties file (simple config equal to example in docs) * Specified the location to the mod_jk.so in server.xml using the ApacheConfig-directive Any ideas about this?

Preventing Session saving
I'm running Tomcat 4.1.18 on WinNT. Is there a setting in the context, manager, etc where I can specify not to try to continue sessions if the application crashes/ is reloaded? My application can't serialize it's session data (doesn't implement serializable) and if the application is reloaded I get NullPointerExceptions. I think it's because the JSession cookie is submitted by the user again -- however the session variables referred to no longer exist and I get NullPointerExceptions. Any ideas? Cheers, Kris

Server.xml / App Context / Redirect question
Hi, I am having trouble configuring Tomcat (server.xml) to use my application, which is (and always will be) the only Java app. running on my server. I am using the built in web server, as I have very little traffic and virtually no static content, so coupling it with Apache is not necessary. How do I configure Server.xml to go directly to a directory of my choosing by just typing in the name of server on the host? (I have successfully changed the port to 80 from 8080, so that is not an issue. I also changed host files on my Intranet so every box knows the name of my server) For example, if I have a server named Titan (this is on an Intranet, not the Internet) with an application in a directory called projectX, I wish to simply launch a browser and type in http://Titan and be directed directly to my web-app's (projectX) front door. I had this working, but somehow I changed something and I am now being directed to the default Tomcat home page. I am having to type http://Titan/projectX into the address bar to get to my app. I did add the default context as such: Context path= docbase=projectX debug=0 / What am I doing wrong? Also, I should NEVER append /projectX/ to a file name when using a response.sendRedirect(), correct? (Ex: response.sendRedirect(/projectX/main.jsp)) This would result in very non-portable code, right? But I DO need the slash before the file name, right? (Ex: response.sendRedirect(/main.jsp)) Any info appreciated.

This is the default getInstance() method of a singleton

public Object getInstance()

if (INSTANCE == null)
{
synchronized (this)
{
if (INSTANCE == null)
{
INSTANCE = this.getClass().newInstance();
}

How to maintain session attributes in a frameset?
Hi, I'm using the following configuration: - Tomcat 4.1.12 - Struts 1.1b3 - JSTL 1.0 - a frameset containing two frames (all JSP) The JSP containing the frameset sets session attributes using the c:set tag from JSTL. The frameset is built by using the Struts tag html:frame ... (relative URLs to frame in the same web-app). The session attributes which are set in the frameset-page cannot be retrieved in the frames because the frames could not be assigned to the session that was created by the frameset. This behaviour occured in all tested browsers (IE 6, Mozilla 4+7, Opera 7). When using Mozilla 7, I deleted the session cookie JSESSIONID. Afterwards, the application worked as intended. However Mozilla did not create any new session cookie. Using URL-rewriting in the frameset showed no effect. Is this a known problem and is there any work-around?

Re: definitive answer on JSPC?
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 On Tue, 2003-02-04 at 23:15, Brett Porter wrote: 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] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
TC 3.2.x : How to get DataSource (Resource) defined on server.xml?

CGI environment vars
Tomcat 4.1.18 : UMN Mapserver CGI I have a CGI which needs to see the LD_LIBRARY_PATH to get to shared libraries to run. However, I can't seem to get whatever shell that Tomcat uses to run CGIs seeded with that variable. I tried putting it in the setenv.sh which is checked for and used in catalina.sh, but that doesn't seem to have any effect on CGIs. Anyone have an idea?

RE: singleton creation (ot)
Very nice reading, but I'm getting convinced that I should not use
Singleton pattern in my case... I just wonder what should I do then :-)
As I said, the method will be called millions of times... so I think
it shouldn't be synch'd (for performance). Certainly I could solve most
of my problems if I could instantiate my singleton in its static
constructor, right? But what I'm really implementing is an abstract
class, and all of its subclasses should be Singletons. I would like to
implement the singleton instantiation routines in the superclass, but I
can't call this.getClass() (as in my code sample) from an static
context...

RE: localhost:8080 connection refused
That's why you are getting connection refused. Tomcat isn't even starting. Can you post the entire contents of catalina.out for a full startup attempt, instead of just the error message? It might help in debugging if we can see exactly when in the sequence this error is thrown. Just null out catalina.out, then try and start Tomcat again. Also, how did you do the installs for Tomcat and Apache? RPM? Source? Binary? Do you have zip/unzip or gzip/gunzip on your system? The error message is calling a native method.

FW: jsp:include semantics?
Hello. What are the semantics of jsp:include in Tomcat 4.0.x? It seems to me that if I jsp:include another jsp, things work fine. But if I try to include a servlet (one that was registered in my web.xml, e.g. url == /mywebapp/myservlet) the servlet is treated as if it were a traditional resource (that is, Tomcat tries to find a file named /mywebapp/myservlet), which of course can't be found since it doesn't exist. Is this behaviour correct? Should I be bugging the Jasper people about this one? Are there any non-standards-breaking ways of getting around this? Thanks...

Redirecting HTTP to HTTPS
Hi, I'm having a problem with redirecting HTTP to HTTPS When a user logs in, and a session variable is created, I then want to redirect them to a secure connection for only one page, which submits private information. If I go directly to https of my server, everything work, since the key is configured correctly. But when I first log into the site and then redirect to https the server or browser hangs, not sure which one. Sometimes it will render half of the page and then hang, sometimes it just hangs. I guess my question is there a problem or something I need to configure. (There are no messages in the error log) Second is what's the best way to redirect to https. Are sessions preserved, or do I have to URL rewrite them? Also, is it a good idea to use a Filter to redirect the pages? Or how would I insure that the connection is secure? Thanks for any help in advance. Ilya
RE: JSP's in other directories
If what you REALLY want to do is make your webapp be able to access resources outside of the webapp structure, and if you want to be non-J2EE, then you can write your own implementation of a JNDI DirContext, and allow it to find resources any way that you want. You just have to register that DirContext implementation using the Resources element for your context... I've done this very thing to allow my Tomcat development environment to access jsp/html/css/etc files from MANY different locations outside of the webapp structure. It works great for a development environment where all of your resources aren't in the shape of a webapp, but you want to be able to have a context running against them as you work... ;) Dave Keyes -Original Message- From: Ming Zhao [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 05, 2003 1:00 PM To: Tomcat Users List Subject: Re: JSP's in other directories You use JK2 as the connector between Apache and Tomcat?

Re: RE: Oracle cursor problem with Tomcat 4.1.12 and Commons BDSF
Not sure if this is any help, but I do have some related information. I believe the problems you are experiencing relate directly to a known bug in the Oracle JDBC drivers. In my case, I found that using a PreparedStatement object in a servlet resulted in 2 or 3 (depending on the complexity of the statement) overhead cursors being opened by Oracle. These cursors did not close, even when the PreparedStatement itself was closed in my code. The orphan cursors only seemed to close if the connection itself was closed - a major problem if one is trying to use any kind of efficient connection pooling. This problem has been acknowledged by Oracle, but they have not, to my knowledge, fixed it. For me, the best solution was to de-tune my connection pool to force connections to be closed sooner than I normally would, in combination with setting a very high value for MAXCURSORS in the init.ora file. After some experimentation, I found a combination of those 2 factors that resulted in no more maximum open cursors errors, with only a modest degradation in performance. A compromise solution to be sure, but one that worked out OK for me. I hope that is useful information.

Re: FW: jsp:include semantics?
Strange. What is your servlet-mapping url-pattern? What is the jsp:forward call that you're attempting to use. Remember that all jsp:forward calls are routed at the context root. Meaning that if your web app resides at /theapp, then jsp:include page=/header.jsp is really /theapp/header.jsp externally. So too with servlet mappings. (I hope that you are not including /mywebapp in your jsp:forward action.) At 12:59 2003-02-05 -0500, you wrote: Hello. What are the semantics of jsp:include in Tomcat 4.0.x? It seems to me that if I jsp:include another jsp, things work fine. But if I try to include a servlet (one that was registered in my web.xml, e.g. url == /mywebapp/myservlet) the servlet is treated as if it were a traditional resource (that is, Tomcat tries to find a file named /mywebapp/myservlet), which of course can't be found since it doesn't exist. Is this behaviour correct? Should I be bugging the Jasper people about this one? Are there any non-standards-breaking ways of getting around this? Thanks...

Re: Setting up Tomcat to run JSP pages...
Tomcat will compile JSP files inside your web application context folder (but outside the WEB-INF folder) into servlets and run them automatically. You could also put JSP files in the WEB-INF folder, but you would have to declare it as a servlet and create a mapping for it. See my message in the thread RE: JSP's in other directories for an example of how to do this. The only method by which I could imagine that you could execute a servlet outside the WEB-INF folder is if the servlet class file is in the class path. So, it could be done. But I definitely would not recommend this approach. I cannot think of any legitimate reason to do something like this. The standard practice is to place servlet class files inside WEB-INF/classes and mapping requests to them in the web.xml file. What reason would you have for deviating from the standard practice? If you really want to learn how to write web application using servlets and JSPs, I recommend picking up a copy of Core Servlets and JavaServer Pages by Marty Hall. You can get an electronic copy of the book online at http://pdf.coreservlets.com/. At 18:59 2003-02-04 -0500, you wrote: Hi, I'm new to Tomcat, using 4.1, and have set up Tomcat to run with Apache...that works.

Re: VirtualHost www.zcompany.com:80 overlaps VirtualHost www.abc.com:80
Yes, that's the way I have mine. I just noticed now that you say that everything is working OK in your original message. So I imagine that it is just a redundancy. I would try and pulling out the relevant info in mod_jk.conf and putting it in http.conf manually. I mention it below. Where are you seeing this warning? Is it in tomcat logs or apache logs? I only have 2 virtual hosts, one for SSL and one for non-SSL. I had to have virtual hosts, so that I could completely separate out SSL and non-SSL traffic, so that non-ssl traffic would be re-directed to a different webapp than ssl traffic. I'm not doing exactly what you're doing so my setup may not be completely applicable. I commented out the #Include /path/to/mod_jk.conf because that would make the JkMounts global. You might want to try and do the same. Here are my recent notes on my configuration that I did after the fact, so I haven't fully tested this to make sure this is exactly what I did. But maybe this helps you. You may notice that I have struts too, so I have a map to *.do files too.

Re: mod_jk2
Hi, I also could not mod_jk2 working after trying for 2 or 3 days. I compiled my own but could never get it working. I tried the combination RedHatLinux-7.3 w/2.4.20kernel/JDK-1.4.1_01/tomcat-4.1.18/apache-2.0.44/mod_jk2 I ended my frustration, by using a binary of mod_jk. If I ever hear of a concrete success story with some info, I may try again. I'm interested in seeing what others say about this. Mod Parent Up... Woops wrong site.

RE: CGI environment vars
Just an idea: Extend the CGIServlet (MyCGIServlet) and override the setCGIEnvironment method (it is protected, so you could call it and then add your variables which you could read from a properties file or something). Then modify the web.xml file found in Tomcat's conf directory to invoke your CGI servlet by changing the servlet-class attribute of the cgi servlet element (servlet-classcom.mycomp.servlets.MyCGIServlet/servlet-class).

I just noticed now that you say that everything is working OK in your original message. So I imagine that it is just a redundancy. I would try and pulling out the relevant info in mod_jk.conf and putting it in http.conf manually. I mention it below. Where are you seeing this warning? Is it in tomcat logs or apache logs? I only have 2 virtual hosts, one for SSL and one for non-SSL. I had to have virtual hosts, so that I could completely separate out SSL and non-SSL traffic, so that non-ssl traffic would be re-directed to a different webapp than ssl traffic. I'm not doing exactly what you're doing so my setup may not be completely applicable. I commented out the #Include /path/to/mod_jk.conf because that would make the JkMounts global. You might want to try and do the same. Here are my recent notes on my configuration that I did after the fact, so I haven't fully tested this to make sure this is exactly what I did. But maybe this helps you. You may notice that I have struts too, so I have a map to *.do files too.

error loading jar files related to modified CATALINA_BASE directory
I am running a tomcat 4.1.18 server in the following way:
The catalina_base directory is set up as /web. This allows me to keep the
distribution of the code seperate from the
version of the tomcat server. It is also useful for deploying multiple
instances on the same machine.
So, I have
CATALINA_BASE=/web
CATALINA_HOME=/usr/jakarta-tomcat4.1.18
Here is the problem:
Any jars in the /web/webapps/application/WEB-INF/lib directory cause an
error when the context is initialized. While starting up, tomcat finds the
jar files, but while loading gives the exception. that it can't find the
file at the requested resource (which seems odd given that it was found
during the scanning process.
the error from the logs and the server.xml file are included below
I've tried several solutions including:
1) putting the jars in the /{tomcat}/shared/lib directory -- the classes in
the jars were not available at runtime.
2) experimenting with the appbase directory. --no effect
3) The problem is NOT related to the struts.jar file. The same error occurs
with the mysql.jar file
The system works when CATALINA_BASE == CATALINA_HOME, but that does not fit
with what I am trying to do for the application.
Any insight would be appreciated
