You need to have tools.jar (in the JDK/lib dir) in your classpath for
Tomcat, since it uses javac to complile the JSPs. Good luck.

Hi folks,

Okay, I'm kind of new to this java stuff, so please bear with me. I think I
have it almost done but have reached a stumbling block which I cannot
resolve by searching through the archives.  I'm sure its a simple one, but
It's got me stumped.

FOR---
Solaris 2.6
Apache 1.3.12
Tomcat 3.2
mod_jk
JDK 1.3

I have my apache set up to use virtual hosts.
I have the tomcat set up pretty much stock, with the exception that I added
ajp13(i'm not using it in my apache configuration though) and I commented
out the /examples, /admin, etc. now all i have in my server.xml file for
context is

        <Context path="/java"
                 docBase ="/export/home/cci/public_html/java"
                 croseContext="true"
                 debug="0"
                 reloadable="true">
        </Context>

then in my httpd.conf file i have
<VirtualHost 111.111.111.111>
        ServerAdmin root@mydomain.com
        DocumentRoot /export/home/cci/public_html
        ServerName my.domain.com
        DirectoryIndex index.cgi index.pl index.html index.shtml
        <Directory /export/home/cci/public_html>
          Options All
        </Directory>

        <Directory /export/home/cci/public_html/cgi-bin>
          Options All
        </Directory>
    AddHandler cgi-script .cgi
    AddHandler cgi-script .pl
        ErrorLog /export/home/cci/public_html/logs/error_log
        TransferLog /export/home/cci/public_html/logs/access_log
 
   <Directory "/export/home/cci/public_html/java">
     Options Indexes FollowSymLinks
   </Directory>
 
  #
  # The following line mounts all JSP files and the /servlet/ uri to tomcat
  #
  JkMount /java/servlet/* ajp12
  JkMount /java/*.jsp ajp12
  #
  # The following line prohibits users from directly accessing WEB-INF
  #
  <Location "/java/WEB-INF/">
      AllowOverride None
      deny from all
  </Location>
        
  #
  # The following line prohibits users from directly accessing META-INF

</VirtualHost>


If I http to my virtualhost:8080 the stock tomcat screen comes up.
If I http to my virtualhost:8080/java then I get the directory index of the
/export/home/cci/public_html/java(as I would expect).

I have created a quick jsp to test my setup which just does the basic html
tags and then does a
<% out.println("test") %>

if I go to http://my.domain.com/java i get the same directory listing as I
would expect. 

the problem is that when i click on test.jsp, i get the following
output.(for either the servername:8080/java or the virtual host).

Error: 500

Location: /java/test.jsp

I checked my workers.properties and it appears to be all okay.  the
tomcat_home and java_home are set correct.  I can run other java
applications okay.

can anybody help me with this? I'm totally stumped and don't know where to
look. I can't find that much documentation on setting up mod_jk with virtual
hosts. I checked out the tomcat_apache howto and the minimalistic approact
to setting up tomcat and all
the other docs that come with it.  I'm sure its just something simple i have
missed somewhere.

any help would be most appreciated.
