Re: 3.3a, cant find file when refresh
I don't know why Keith, but I have been able to reproduce the same situation here. It appears you can't have a jsp:include .. tag on the first line of your jsp file without problems in Tomcat 3.3.

Re: workers.properties Configuration??
You don't have to configure it if you are running Tomcat standalone, but you do have to configure it if you are running Tomcat with Apache.

Re: jsp function declaration
If that is the correct code for the method, then the problem is you have a closing
brace
for the else without an open brace. What's probably happening is the brace you think is
closing the else is actually closing the method, and the brace you think is closing the
method is closing the entire class before the service method is auto generated during
conversion to a servlet, thus the error. Either add an opening brace for the else, or
remove one of the closing braces at the end.

Re: FW: mod_jk and mod_jserv compiling problems
That's because you are in Solaris, and Sue was working in Linux. Fortunately, I also have a Solaris box for reference here. Your lines should look like: my $CFG_LD_SHLIB = q(ld); # substituted via Makefile.tmpl my $CFG_LDFLAGS_SHLIB = q(-G); # substituted via Makefile.tmpl my $CFG_LIBS_SHLIB= q();# substituted via Makefile.tmpl Now I see that this one is actually using ld, which is what I suspected from the beginning. There is an option to apxs when compiling under Solaris, -lposix4 I believe, that is highly recommended. I know it is picky about where in the apxs the option appears. I would search the archives for posix and see what turns up. Hope this helps. -Scott -- Scott Tatum | [EMAIL PROTECTED] Senior Applications Developer, Special Projects WorldCom | http://www.wcom.com/ Kevin Shortt wrote: well configured limits on this list do not allow me to send my full output of my problem.

I think what you need to do next is check your version of perl. I am guessing you have 5.005 or somewhere thereabouts. Check it by doing perl -v. Make sure you have 5.x.

Re: mod_jk and mod_jserv compiling problems
I think you were on the best track with #3, compiling and installing Apache yourself first. When you compile Apache, make sure that your configure line has at least the --enable-shared=so option so that you can your your mod_jk DSO. I usually compile with --enable-shared=max option so that I can remove modules if I don't need them by commenting them out in httpd.conf. You want to compile mod_jk, not mod_jserv, and you don't want to get a precompiled version from somewhere. Your best best is to get both the binary and source versions of Tomcat 3.2.1. Install the binary version (basically just untar it where you want it and set the TOMCAT_HOME environment variable). Untar the source version just to compile mod_jk.so. Change to the src/native/apache1.3 directory under the Tomcat source directory. Enter this line, replacing JAVA_HOME with the directory of your jsdk installation (e.g. /usr/java/jdk1.3.0_02): apxs -o mod_jk.so -I../jk -IJAVA_HOME/include -I/JAVA_HOME/include/linux -c *.c ../jk/*.c If apxs is not in your path, then you will have to put the absolute path for apxs in order for it to see it. For example if your apache bin directory is /home/httpd/bin, then you replace apxs with /home/httpd/bin/apxs. Once you run this, you'll have a mod_jk.so in that directory. Move that file to the libexec directory under the Apache directory. Then edit httpd.conf and put in LoadModule and AddModule directives in order with the other directives: LoadModule jk_module libexec/mod_jk.so AddModule mod_jk.c I think the mod_jk.conf-auto adds its own LoadModule line. You will want to copy mod_jk.conf-auto to mod_jk.conf, remove the LoadModule entry from that file, and include that file in httpd.conf. Any more questions, just ask. -Scott Sue Evans wrote: Hello, I have spent days trying to get tomcat configured. I can't seem to get/create either mod_jk or mod_jserv that will work. I am on Linux 6.2, using Apache 1.3 and Tomcat 3.2.1 . I have tried the following with these results: 1. First tried using the Apache server that installed automatically when I installed Linux. Problem is that nowhere on my system could I find apxs - so I copied it form another Linux installation. I tried to then compile mod_jserv. Keep getting an error when I run the command apxs -c -o mod_jserv.so *.c to create mod_jserv. Get the error :No such file or directory. I don't know what it is referring to - it is finding apxs okay, what file or directory is it referring to? 2. Next I tried copying the binary mod_jserv from the tomcat download site and that didn't work either. When I went to startup apache, I get the error: Loade DSO libexec/mod_jserv.so uses plain Apache 1.3 API, this module might crash upon EAPI. Please recompile it with -DEAPI! I have no idea what this means. 3. Next I tired compiling my own Apache version 1.3 and got that all installed with DSO enabled. Again, tried creating the mod_jserv and mod_jk files using apxs and again got the error No such file or directory. Still don't know what that is referring to. 4. Next tried using the binary mod_jserv that I had downloaded from the tomcat download site. Didn't work. Apache won't start. I get no errors, nothing in the log files, nothing in configstatus, NOTHING! (very frustrating). Just says not started. 5. Next I tried using the binary mod_jk that I had downloaded from the tomcat download site. Didn't work. Apache won't start. This time I at least get an error message. It says API module structure 'jk_module; in file /usr/local/apache/libexec/mod_jk.so is garbled - perhpas this is not an Apche module DSO? Apache could not be started. (I tried re-downloading it but to no avail!) So... any ideas? To recap: 1. The downloaded binary mod_jk.so and mod_jserv.so don't seem to work. 2. I can't create new mod_jk.so or mod_jserv.so because apxs reports No such file or directory when I enter the commands as given in the documentation.

Re: mod_jk and mod_jserv compiling problems
I'm not sure, but it looks like it's bombing when it's done compiling and is trying to link all the object files together. Perhaps it is trying to find the ld command and can't?

Sue, I did some looking in the tomcat-user archives, and found several posts along these lines. I think what you need to do next is check your version of perl. I am guessing you have 5.005 or somewhere thereabouts. Check it by doing perl -v. Make sure you have 5.x. Once you've done that, go and edit the apxs file (it's a perl script). You should see some lines like this after the initial comments are done: my $CFG_LD_SHLIB = q(gcc); # substituted via Makefile.tmpl my $CFG_LDFLAGS_SHLIB = q(-shared); # substituted via Makefile.tmpl my $CFG_LIBS_SHLIB= q();# substituted via Makefile.tmpl They should look like this (I pasted this from my apxs which is on RH62, Apache 1.3.19). In particular I'm guessing the CFG_LD_SHLIB may be incorrect. Try changing those lines to this if they are different and compile again. -Scott Sue Evans wrote: Hello all, I still have not been able to get mod_jk working. If anyone has any ideas, I'd like to hear them! I did FINALLY get mod_jserv working. Here is what I did: I decided to try to follow the instructions for downloading Jserv binaries that someone sent in an earlier reply to my problem. 1. First went to http://java.apache.org/jserv/install/howto.unix_install.html 2. From there it gives specific requirements for building Jserv. I didn't previously have the Java Servlet Development Kit 2.0, so I got that from http://java.sun.com/products/servlet/archive.html . (Maybe this is related to my problems with mod_jk?) 3. I untarred the JSDK2.0 and put it in a directory on my system. 4. THen, I downloaded the Jserv binary from http://java.apache.org/jserv/dist .(There are a bunch or rpms which I avoided and got the gz file, and opened that into a temp directory on my system. 5. THen, I went back to http://java.apache.org/jserv/install/howto.unix_install.html and followed the instructions from the section titled Configure Apache JServ, and from the email from Sendai. He says: ./configure --prefix=/usr/local/jserv --with-apxs=/usr/local/apache/bin/apxs --with-jdk-home=/path/to/jdk --with-JSDK=/path/to/jsdk.jar --disable-debugg ing (Note: I didn't find a jsdk.jar file on my machine anywhere, but I put the path to where I had installe jsdk2.0 in step 3 above and that seemed to work okay.) And Wallah! It worked! Geeze! What an incredible task this was! I have to say that previously on another Linux machine, I followed the basic instructions for compiling the mod_jserv by downloading the src distribution of tomcat and then going into the src/native/apache/jserv directory and typing the command apxs -c -o mod_jserv.so *.c and it worked like a charm. I don't know why it isn't working on this setup, but it isn't. And like I said, I never could get mod_jk working -- and that seems to be the preferred way to set this up.

Re: mysql jdbc driver
The best place depends on how you are going to be using it. There are three main options: 1. in JAVA_HOME/jre/lib/ext 2. in TOMCAT_HOME/lib 3. in WEB-INF/lib of a given application I tend to put driver jars like this in 1, since putting it there automatically makes it available to everything using the JRE. Since I sometimes write programs outside of Tomcat (e.g. nightly jobs, etc), putting it there makes it available everywhere automatically, with no changes to the classpath. (note: only with jdk = 1.2, which Tomcat requires) You could put it in 2, if you only need JDBC connectivity to Mysql in your webapps. You would use #3 if you knew you only needed it for one web app. Jar files placed in 3 are only visible to the particular web app, jar files placed in 2 are visible to all web apps, and jar files placed in one are visible everywhere.

Apache+Tomcat+vhosts insights, discussion (long)
ly gets confused by the differing server names, and enters the CPU loop. Putting a VirtualHost entry first in the list without any Tomcat directives stops this problem. Even requests to pserv.wcomnet.com/somefile.jsp just return a 404 since there are no JkMount directives for that vhost. So there is my perspective on the utilization issue. Like I said, I don't know how representative this configuration is, but I hope someone else benefits from what I've discovered. In addition, though the packaged documentation had everything I needed, it was spread across several files and made it frustrating initially. I think a separate, concise guide on setting up virtual domains would do a world of good for those going this route (which I'm betting is a lot). One that provides the configuration steps for Tomcat standalone, Apache+Tomcat, as well a section on separate VM's for each host/app. It should deal only with mod_jk - the docs were mixed mod_jk and mod_jserv, and this only added to the confusion. I would be more than willing to write this documentation, as I have setup several servers now using each of these configurations. I'm experimenting with ajp13 now, so I would probably have a section on using ajp12 vs. ajp13. The one thing I wouldn't be able to write on is using SSL as I haven't done that yet. Would anyone be interested in this? I see a LOT of mails posted to the group asking about Apache+Tomcat+vhosts. If there is enough interest, I will go ahead and start on the documentation, and if the Tomcat people don't want to include it I can throw it up on my website. I almost need to to it just for myself, to make it easier the next time I have to configure a server. :) The initial version would be configuring for unix, though if I actually do it, I'll do some setups on Windows boxes and add documentation for that platform. -Scott (p.s.

Re: Problems with caching?
Are you using the include file directive to include the files? If you are, then that is the problem. JSP's won't recompile if a file they include is updated, only if the jsp file itself is updated. There are two ways to get around this: 1. Load the jsp file and save it (may have to add a space, remove it, then save or something similar) 2. Use the touch command unix to update the timestamps on all your jsp files. This will cause them all to recompile. (e.g. go to your dir with the jsp's and do a "touch *.jsp") This might be preferable since you are dealing with header includes. Hope this helps. -Scott Melissa Matthews wrote: Does anyone know if there is a problem with regular HTML files being somehow cached by Tomcat 3.2.1 on Solaris 2.8?

Re: Which workers am I using?
In order to get Apache to use ajp13, you have to use your own config files. The auto files always use ajp12. You'll need to change workers.properties so that your workers have a type of ajp13. I don't think it matters what your workers are called, though most people have the protocol as part of the worker name. It's possible that your worker could have a name with ajp12 in it, even though its type is ajp13 and it might make deceiving log entries that way. -Scott -- Scott Tatum | [EMAIL PROTECTED] Senior Applications Developer, Special Projects WorldCom | http://www.wcom.com/ Peter Smith wrote: I can see the ajp12 and 13 worker threads being instantiated (via log messages in the console) when I crank up Tomcat, but how do I know if the 13's are being used at all?

Re: virtual hosting with tomcat and apache
Your first message went through. Tomcat can do exactly what you need. It can be configured to run several vhosts, each as their own application. Normally you give each vhost its own Tomcat instance, to provide a clean separation of runtime enviroments between sites. It also gives you the ability to restart one Tomcat instance without having to bring them all down (at least, with ajp12). I believe that you can also run them all under one Tomcat instance. I have done this before with Tomcat standalone, I assume it also works connected to Apache, but I recommend going the separate VM route if you are running vhosts. I recommend the latest version of Apache (currently 1.3.19) and Tomcat 3.2.1. I think 3.2.2 will be out in the next couple of weeks, it would be a good choice as well. You should use mod_jk, and not mod_jserv. I recommend getting both the binary and source versions of 3.2.1. Use the binary version for Tomcat itself, and use the source version just for compiling mod_jk. Configuring Apache+Tomcat+mod_jk+vhosts is not a trivial task for sure, and there's not a concise resource for setting it all up. The documentation that comes with Tomcat has a lot of information, but the pieces you need are spread across several documents. Be sure to read the mod_jk howto, as well as the workers howto. As far as configuration goes, don't use the automatically generated config files - they aren't going to have what you want for vhosts. Just create them from scratch. With the aforementioned setup, the important config files are server.xml, workers.properties, uriworkermap.properties, and mod_jk.conf. A few other files (web.xml, web.dtd, tomcat-users.xml, tomcat.policy) are also important, just not usually for initial setup. When you find the section in the documentation that talks about creating a separate server.xml file for each vhost, you are looking in the right place. In order to do separate VM's that is the route you need to go. Also, watch out for the dreaded CPU loop, which is easy to do with virtual hosts. See the 3.2.1 release notes, section 6.11 for that. I've had some interesting experiences with that issue in the past couple of days, and I'm going to make a separate post to the group with some insights I haven't seen posted yet. Tomcat is well suited for what you want to do, but I can assure you it's going to take a couple of hours minimum figuring out how to configure it the way you want it. So grab your favorite drink and have a seat. If you encounter any snags along the way (which you will) mail to the group or to me personally, preferably to the group. I will respond either way. :) (now that I have caught up on my 1500 message backlog, ugh) Good luck! -Scott -- Scott Tatum | [EMAIL PROTECTED] Senior Applications Developer, Special Projects WorldCom | http://www.wcom.com/ Brandon Cruz wrote: I sent a message a while ago, but don't think it went though.

Subject: Strange custom class behaviour with subdirs in 3.2.1
First, the obligatory setup info:
Tomcat 3.2.1 using built-in webserver changed to port 80.
RedHat 6.2
Sun JDK 1.3.0_02
I'm having a strange problem that I did not have while using JRun, and
I'm hoping someone can shed some light.
The situation is simple - say I have a webapp called blah. In blah's
WEB-INF/lib directory I have a jar file with some classes that I use
frequently. One of these classes is StatsBean. Then I have all my jsp
files in the docBase and I can use the StatsBean fine.
I also have a helpdesk directory off of the docBase (i.e.
webapps/blah/helpdesk) which also needs to use the StatsBean. If I have
a jsp file in the helpdesk directory that tries to declare/use a
StatsBean, or any of my custom classes, I get this kind of error:
(this example is a webapp called ct-dev whose context path is / and is
compiling /helpdesk/helpdesk.jsp)
org.apache.jasper.JasperException: Unable to compile class for
JSP/usr/tomcat/work/xxx.xxx.xxx.xxx_8080/_0002fhelpdesk_0002fhelpdesk_0002ej
sphelpdesk_jsp_0.java:73:
Class helpdesk.StatsBean not found.
StatsBean statsBean = (StatsBean)
session.getAttribute("statsBean");
For some reason it thinks all my classes should be in a helpdesk package
because the URI has helpdesk in it. Is this expected behaviour? I did
not have this problem in JRun. I would expect to be able to use my
classes anywhere in the web application, not just the app root. The
problem manifests itself both with classes in the WEB-INF/classes dir,
and classes in jars in the WEB-INF/lib dir.
I'm certainly not counting out a configuration problem. If I need to
post the contents of my configuration files I can. Of course, I don't
really even know what all configuration files are used! As far as I can
tell, the standalone tomcat only needs server.xml and web.xml. A lot of
them seem to be only for mod_jk and/or mod_jserv. It's hard to tell from
looking at the mass of config files in the conf directory what is needed
by tomcat standalone, tomcat+apache, etc. It would be nice to have a
document that explains every file in the conf directory and what it is
needed for. That way I could do some cleanup and know that the files I
have in there all have something to do with my setup. I have this
feeling that several of them are jserv (i.e. not mod_jk) related and
could be removed in most situations. Now watch someone point me to just
such a file that probably comes with Tomcat. 8-)

Startup AND shutdown of separate JVM's
I have been using Tomcat for a while now and with good success. I recently setup virtual hosts (named vhosts) and was surprised when it all worked the first time. =) The documentation in the mod_jk-howto was a great help. Here is my setup: I have two different (eventually more) virtual hosts on one machine being served by Tomcat 3.2.1 and Apache 1.3.14. Right now there is only one Tomcat JVM running, but I'm getting ready to break this up into 2 separate JVM's. The configuration part is trivial now that I have virtual hosts working, but there is one part I can't figure out. The two vhost setup is for production and development versions of the same application. So one JVM I will need to restart regularly, and the other needs to stay up as much as possible. There are a couple of problems I forsee that I need to understand and tackle before moving forward. One is that there is only startup/shutdown script for Tomcat. I understand that, by creating different server.xml configuration files and using (e.g.) startup.sh -f server1.xml, I can start separate servers. My question is, how do I stop them separately? If I have to write my own scripts I am willing to go that route, I just want to make sure there's not some preexisting method. Also I read in the FAQ that if you restart Tomcat, you also have to restart Apache. I've tested this out with mixed results. Is this true? If that is the case, running separate JVM's for each website becomes useless to me. No offense to the other benefits of running separate JVM's! If I have my production JVM which needs to stay up, but Apache has to restart every time I restart my development JVM, wouldn't that mean I have to restart my production JVM every time I restart my development JVM? Worst case, I can run my development on the built-in webserver, but it would be nice to use app.domain.com and app-dev.domain.com without having to tack on a :8080. So in review, my questions are: If running separate JVM's connected to a single Apache, how do I restart one JVM while leaving the other running? Also, if running under said setup, does restarting one Tomcat JVM mean that Apache and any other Tomcat JVM's have to be restarted as well? Thanks in advance for any insight. -Scott (p.s. was running JRun 3 before Tomcat. Experienced daily lockups. No lockups with Tomcat and it is noticeably faster.
