As I am newly subscribed to this list, I don't know if you have got a satisfactory answer for your question, but if you don't; I have the same configuration like yours, static files are served by Apache and *.jsp files are served by Tomcat. That's exactly what I want. All you have to do is to use Java Connector to mount jsp files to Tomcat. You can find the necessary documentation in Connectors part of Tomcat documentation. Aha! Yes, AJP connector looks like what I need. Unfortunaely the documentation doesn't seem to show how to do this. If you can't get out of it, I can help you set it up off or on list.

Unfortunately the Tomcat I am using is one I installed from source, as I didn't know at the time that Red Hat had gotten around to making an RPM...and their RPM doesn't appear to support Cocoon (I tested it on a clone box and adding the war file to webapps just causes error messages about missing jar files to go into the logs). If you see mod_webapp RPM, run for your life. I'm getting good at that :-) As a workaround, you should be able to use mod_proxy to proxy requests for TC to it.

[...] Has anyone managed to serve JSP with Tomcat on a RHEL4 machine running their stock httpd? You're looking for mod_jk RPM or mod_jk2 (which has been dropped from development). I found mod_jk-ap20-1.2.10-1jpp.i386.rpm at http://www.jpackage.org and It installed without error on RHEL4 running stock httpd-2.0.52-9.ent.rpm So far, so good. So I added the suggested element Listener className=org.apache.jk.config.ApacheConfig modJk=/usr/lib/httpd/modules/mod_jk.so / to the Engine name=Catalina ... container in server.xml and restarted Tomcat. This created /usr/local/jakarta-tomcat-5.5.9/conf/auto/mod_jk.conf (NOT mod_jk.conf.auto as the Jakarta Tomcat Connector Apache HowTo documentation says). The mod_jk.conf was pretty skeletal, so I added: JkWorkersFile /usr/local/jakarta-tomcat-5.5.9/conf/workers.properties and edited workers.properties to reflect the locations workers.tomcat_home=/usr/local/jakarta-tomcat-5.5.9 workers.java_home=/usr/java/jdk1.5.0_03 and added this line to /etc/httpd/conf/httpd.conf Include /usr/local/jakarta-tomcat-5.5.9/conf/auto/mod_jk.conf and finally restarted Apache. No error, but it doesn't do anything meaningful with my JSP files: it just serves them through Apache. Looking in mod_jk.conf I see it mentions all the subdirectories in Tomcat's webapps directory, but nowhere does it reference any directories in my Apache document tree. I've obviously missed how to get it configured to serve JSP files from the Apache web server directories. I have no interest in serving any JSPs from the Tomcat directories, as all I use Tomcat:8080 for is serving Cocoon, which already works fine. The JkMount directives in mod_jk.conf all refer to /directory being in Tomcat's webapps directory. How do I reference directories which are actually below /var/www/html so that they get handled by Tomcat? In mod_jk.conf, what does this refer to: VirtualHost localhost ServerName localhost The Tomcat:8080 server or the Apache httpd:80 server? If it's Tomcat, then I can understand why JkMount /directory refers to Tomcat's webapps, but it seems very weird that the autoconf should configure mod_jk.conf to mount only Tomcat's directories, when the entire point of the operation is to enable serving of Apache's own JSP files. If it's Apache's httpd, which it is presumably intended for, as this file gets Include'd from Apache's httpd.conf, then why does it still refer to localhost instead of picking up the ServerName from the httpd.conf? Should I change both localhost's to my server's FQDN? ///Peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Where to put java code
I'm running jakarta-tomcat-4.1.18 for the purpose of serving with Cocoon, and that's working fine. But I also have a handful of users who have small .jsp files, most of which are trivial (the files, not the users :-)...with one exception, which calls on a custom search bean. This was working fine under the old JServ, but I can't make it work under jakarta-tomcat. The error messages in all the localhost_log.-MM-DD.txt files say: 2003-07-07 09:37:01 Error compiling file: /usr/local/tomcat/jakarta-tomcat-4.1.18/work/Standalone/localhost/_/info/eolas/2002/3_11/search_jsp.java [javac] Compiling 1 source file /usr/local/tomcat/jakarta-tomcat-4.1.18/work/Standalone/localhost/_/info/eolas/2002/3_11/search_jsp.java:48: package ie.b2bsoft.eolas does not exist ie.b2bsoft.eolas.SearchBean Search1 = null; ^ so I've obviously put it in the wrong place, but the Class Loader HOW-TO at http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html says: For classes and resources specific to a particular web application, place unpacked classes and resources under /WEB-INF/classe of your web application archive, or place JAR files containing those classes and resources under /WEB-INF/lib of your web application archive. [presumably that should be classes in the second line], which is exactly where I *have* put the unpacked stuff. This server also runs regular Apache, and the JSP users all have regular HTML sites under the Apache docroot, so I have softlinked that docroot to ROOT in my jakarta-tomcat-4.1.18/webapps (yes, I know it's a horrible thing to do). In that docroot is a WEB-INF directory containing the classes subdirectory containing the unpacked classes thus: /usr/local/tomcat/jakarta-tomcat-4.1.18/webapps/ROOT/WEB-INF/classes/ie/b2bsoft/eolas: drwxrwxr-x2 root root 4096 Oct 12 2001 . drwxrwxr-x3 root root 4096 Oct 12 2001 .. -rw-rw-r--1 root root 1976 Oct 12 2001 HParser.class -rw-rw-r--1 root root 1180 Oct 12 2001 HParser.java -rw-rw-r--1 root root 3218 Oct 12 2001 SearchBean.class -rw-rw-r--1 root root 2111 Oct 12 2001 SearchBean.java The error message refers to a package (by which it presumably means a jar file?) but the classes were supplied unpacked so I typed jar cf eolas.jar . in the classes directory and moved the eolas.jar file to the lib directory...still no change.

Re: Serving files from the Apache docroot
John writes: There's no need to mirror content in two directories, nor is there any need to point Tomcat at Apache's content root. You can just make Apache's doc root the same as Tomcat's Context root and the issue goes away. Or, just put your JSP and servlets in Tomcat's doc root and leave it like that. That did occur to me but I didn't try it, assuming that if the JSP file referred to other resources, it would break because they weren't in the Tomcat doc root. I'll try it and see. If you have Apache serving static content like images, those images don't have to be in your web application's root at all if you don't want them to be.

Henning wrote: I had and have the same problem - and didn't find a solution yet. A more or less good workaround I discussed with (or better was a suggestion by) Mike Bachrynowski (who is also member on the list) could be to completely mirror the apache docroot to the tomcat docroot. This in my eyes is 'a little' waste of disk space and an alternative I though about is, to set the tomcat docroot to the same local dir the apache's points to - but I haven't tested this, maybe causes bad bad problems. Pretty much what I did: soft link the Apache docroot to webapps/ROOT. Horrible, but it seems to work. As far as I understood the mayor cause for all this is, that jk2 developers due to performance reasons don' t want to send back requests (for images, .js, .css ...) to the apache and - what you and Mike and I want to do becomes impossible. -- LIST: is this right (I'm not really sure whether I should believe it)? This is very suboptimal :-) I can understand not wanting to fire a lot of requests back to Apache, but the designers seem not to have envisaged the need for some sites just to serve a handful of .jsp files. Tomcat seems to be written exclusively for serving vast fully-fledged Web Apps (corporate style), and the occasional JSP user is left out in the cold. Fortunately our new Web site design won't use JSP at all, so I can eventually take Tomcat back to where I want it, serving Cocoon :-) What I'm asking myself: is there anybody on the list who is really highly experienced in jk2 configuration? I'm not sure configs will help: it's a conceptual matter by the look of it. ///Peter -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

I think this has been asked ad nauseam on the Cocoon list, and I think I read that it wasn't advised because Tomcat was not designed to be secure in the way Apache is. I find that hard to believe, given the high quality of most of the work. This should be a FAQ (if it already is, I haven't found it). I don't know how Tomcat would or would not scale as a replacement for Apache on a big site, but it would certainly be nice to have it run on port 80 as a replacement for Apache. ///Peter -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
