Subject Mod_jk & apache
Date Fri, 17 Jan 2003 03:46:16 GMT
Hi,

I just upgraded my connector from webapp to jk since almost everyone is 
telling that webapp will die soon.

But after I installed all the components for mod_jk, my apache seems not 
talking to tomcat anymore. Every time I browse to a jsp page, it will 
said 404 error , and I also found that the jsp was served under port 
16080, but I remember I didn't configure apache to do that.

If I run tomcat from port 8080, it will function well, same goes to 
apache, so I guess they are ok by their own, but not together.

Anyway, I attached all the logs that I can find in my machine, the 
mod_jk.log was empty so I guess the connector was never been triggered 
at all.

Hope somebody can give me a big me on this.

Thanks in advance.

Wai


I running on :-
OS X 10.1.4
Apache 1.3.26
Tomcat 4.0.6 with mod_jk

<!-- A "Server" is a singleton element that represents the entire JVM,
      which may contain one or more "Service" instances.  The Server
      listens for a shutdown command on the indicated port.

      Note:  A "Server" is not itself a "Container", so you may not
      define subcomponents such as "Valves" or "Loggers" at this level.

   <!-- A "Service" is a collection of one or more "Connectors" that share
        a single "Container" (and therefore the web applications visible
        within that Container).  Normally, that Container is an "Engine",
        but this is not required.

        Note:  A "Service" is not itself a "Container", so you may not
        define subcomponents such as "Valves" or "Loggers" at this level.

   <!-- Define the Tomcat Stand-Alone Service -->
   <Service name="Tomcat-Standalone">

     <!-- A "Connector" represents an endpoint by which requests are 
received
          and responses are returned.  Each Connector passes requests on 
to the
          associated "Container" (normally an Engine) for processing.

          By default, a non-SSL HTTP/1.1 Connector is established on port 
8080.
          You can also enable an SSL HTTP/1.1 Connector on port 8443 by
          following the instructions below and uncommenting the second 
Connector
          entry.  SSL support requires the following steps (see the SSL 
Config
          HOWTO in the Tomcat 4.0 documentation bundle for more detailed
          instructions):
          * Download and install JSSE 1.0.2 or later, and put the JAR 
files
            into "$JAVA_HOME/jre/lib/ext".
          * Execute:
              %JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA 
(Windows)
              $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA  
(Unix)
            with a password value of "changeit" for both the certificate 
and
            the keystore itself.

          By default, DNS lookups are enabled when a web application calls
          request.getRemoteHost().  This can have an adverse impact on
          performance, so you can disable it by setting the
          "enableLookups" attribute to "false".  When DNS lookups are 
disabled,
          request.getRemoteHost() will return the String version of the
          IP address of the remote client.

Persistent
		       Sessions.

                saveOnRestart: If true, all active sessions will be saved
                  to the Store when Catalina is shutdown, regardless of
                  other settings. All Sessions found in the Store will be
                  loaded on startup. Sessions past their expiration are
                  ignored in both cases.
                maxActiveSessions: If 0 or greater, having too many active
                  sessions will result in some being swapped out. 
minIdleSwap
                  limits this. -1 means unlimited sessions are allowed.
                  0 means sessions will almost always be swapped out after
                  use - this will be noticeably slow for your users.
                minIdleSwap: Sessions must be idle for at least this long
                  (in seconds) before they will be swapped out due to
                maxActiveSessions. This avoids thrashing when the site is
                  highly active. -1 or 0 means there is no minimum - 
sessions
                  can be swapped out at any time.
                maxIdleSwap: Sessions will be swapped out if idle for this
                  long (in seconds). If minIdleSwap is higher, then it 
will
                  override this. This isn't exact: it is checked 
periodically.
                  -1 means sessions won't be swapped out for this reason,
                  although they may be swapped out for maxActiveSessions.
                  If set to >= 0, guarantees that all sessions found in 
the
                  Store will be loaded on startup.
                maxIdleBackup: Sessions will be backed up (saved to the 
Store,
                  but left in active memory) if idle for this long (in 
seconds),
                  and all sessions found in the Store will be loaded on 
startup.
                  If set to -1 sessions will not be backed up, 0 means 
they
                  should be backed up shortly after being used.

                To clear sessions from the Store, set maxActiveSessions, 
maxIdleSwap,
                and minIdleBackup all to -1, saveOnRestart to false, then 
restart
                Catalina.

   <!-- The MOD_WEBAPP connector is used to connect Apache 1.3 with 
Tomcat 4.0
        as its servlet container. Please read the README.txt file coming 
with
        the WebApp Module distribution on how to build it.
        (Or check out the "jakarta-tomcat-connectors/webapp" CVS 
repository)

        To configure the Apache side, you must ensure that you have the
        "ServerName" and "Port" directives defined in "httpd.conf".  Then,
        lines like these to the bottom of your "httpd.conf" file:

          LoadModule webapp_module libexec/mod_webapp.so
          WebAppConnection warpConnection warp localhost:8008
          WebAppDeploy examples warpConnection /examples/

        The next time you restart Apache (after restarting Tomcat, if 
needed)
        the connection will be established, and all applications you make
        visible via "WebAppDeploy" directives can be accessed through 
Apache.
