Tomcat adds support for Java servlets and JavaServer Pages (JSP's) to the Apache web server.

Restarting the server without recompiling the java pages resulted in a 404. See jsp pages not found.

that file should be included into httpd.conf instead. The

/usr/local/apache/conf/tomcat-mod_jk.conf determines the path to
mod_jk.so. You are better off
if you put mod_jk.so in /usr/local/apache/libexec/. It might work elsewhere, but it
could be hard to get everything to work.
If, during startup, the mod_jk.log
file has messages about not being able to find
mod_jk.so, then make sure
/etc/init.d/gsrc start is run when
in the /usr/local/apache directory.
We had a problem with blank pages, see
JSP pages not found
The next step is What is Struts and how do I install it?
Tomcat is the Reference Implementation for the Java Servlet 2.2 and JavaServer Pages 1.1 Technologies. It adds support for Java servlets and JavaServer Pages (JSP's) to the Apache web server.
cd /usr/local gtar -zxf /export/home1/root/tools/downloads/apache-tomcat-4.1.39-LE-jdk14.tar.gz
Make /usr/local/tomcat a symbolic link to
the directory that was just created:
cd /usr/local rm tomcat ln -s apache-tomcat-4.1.39-LE-jdk14 tomcat
Edit /usr/local/tomcat/conf/server.xml.
With patience, one could probably enable the demo webapps along with
the GSRC webapp, but I didn't get much sucess until I trimmed
server.xml down to bare essentials. As of 12/12/02 (after adding
the Chess application) that means this:

When Tomcat starts up, with this configuration, and with mod_jk
installed (see below), it generates a file called
/usr/local/tomcat/conf/auto/mod_jk.conf to be included
into apache's httpd.conf with the "Include" directive.
To avoid a race condition on startup, this file should be copied by
hand to /usr/local/apache/conf/tomcat-mod_jk.conf, and
that file should be included into httpd.conf instead. The
caveat here, of course, is that you have to re-copy this file if you
ever change any mod_jk-related configuration that effects this file.

Old jakarta installation instructions
(6/05:
http://archive.apache.org/dist/jakarta/tomcat-4/archive/v4.0.4/src/jakarta-tomcat-connectors-4.0.4-src.tar.gz) unzip it into/home/tools. cd into its "jk" directory.The README file here says to copy & edit build.properties and run "ant install". This didn't install mod_jk.so as expected for me.
I had to go down into subdirectory jk/native/apache-2.0, read the README.solaris file there & do what it says:
Ignore the rest of the instructions in this directory about apache configuration. They pertain to Tomcat version 3. Refer instead to
- edit build-unix.sh, setting JAVA_HOME and APACHE_HOME to the right pathnames, and run build-solaris.sh, as root.
- also add the "-DEAPI" flag to the apxs command that does the compiling in build-solaris.sh (in response to errors I got below)
- As root,
$ sh build-solaris.shI had to copy mod_jk.so by hand:cp .libs/mod_jk.so /usr/local/apache/modules/http://tomcat.apache.org/tomcat-4.0-doc/config/ajp.htmlfor information about configuring apache.
Create a new /etc/init.d/tomcat script that invokes /usr/local/tomcat/bin/startup.sh and shutdown.sh. This includes first setting $JAVA_HOME to /usr/java. It also includes setting two environment variables before invoking /usr/local/tomcat/bin/startup.sh: JAVA_OPTS is set to "-Xms128m -XMx128m" to double the heap size of Tomcat's JVM, and LD_LIBRARY_PATH to "/home/www/gsrcwww/java/WEB-INF/lib" to find the JNI libraries. As of 6/05, /etc/init.d/tomcat looks like this, but it is bound to have undergone changes since this time. :

There is now a conflict stemming from the web app being based at URL "/gsrc". Pages that used to be dealt with by PHP as pointing to the "gsrc" workgroup now never get handed off to PHP by Apache at all. For this reason I've changed tomcat's root URL from "gsrc" to "gsrcj". This has required a handful of code changes in both PHP and JSP/servlet code. This string, "/gsrcj" is now a servlet configuration parameter in /usr/local/tomcat/conf/server.xml.
