Hi Cui,

I think that you are missing the shm directive in workers2.properties
and jk2.properties.  Adding that directive should make everything go.

Subject: Need your help about In-process jk2 connection between Tomcat
and Apache on Windows 2000

Hello All,

I am doing in-process connection for Tomcat and Apache using jk2 on
Windows 2000. The installed components are as below:

Tomcat 4.1.24
Apache 2.0.46
mod_jk2-2.0.43.dll

I have done following operation:
1. Install Tomcat in E:\jartomcatflex, it is correct.
2. Install Apache in E:\Apache2.0.46\Apache2, it is correct.
3. copy mod_jk2-2.0.43.dll to
E:\Apache2.0.46\Apache2\modules\mod_jk2.dll
4. Add following command line in httpd.conf:
        LoadModule jk2_module modules/mod_jk2.dll
5. Add workers2.properties file under E:\Apache2.0.46\Apache2\conf, it
likes below:

            # Define the comunication channel 
                        [channel.jni:jni]
                        info=The jni channel, used if tomcat is started
inprocess

                        # Define the parameters for the Java Virtual
Machine
                        [vm:]
                        info=Parameters used to load a JVM in the server
process
        
OPT=-Djava.class.path=e:\jartomcatflex\bin\tomcat-jni.jar
                        OPT=-Dtomcat.home=e:\jartomcatflex
                        OPT=-Dcatalina.home=e:\jartomcatflex
                        OPT=-Xmx128M

                        # JNI worker startup handler
                        [worker.jni:onStartup]
                        info=Command to be executed by the VM on
startup. This one will start tomcat.
                        class=org/apache/jk/apr/TomcatStarter
                        ARG=start
                        stdout=e:\Apache2.0.46\Apache2\logs\stdout.log
                        stderr=e:\Apache2.0.46\Apache2\logs\stderr.log

                        # JNI worker shutdown handler
                        [worker.jni:onShutdown]
                        info=Command to be executed by the VM on
shutdown. This one will stop tomcat.
                        class=org/apache/jk/apr/TomcatStarter
                        ARG=stop

                        # Map the Tomcat examples webapp to the Web
server uri space
                        [uri:/examples/*]
                        info=Map the whole webapp

6. Modify jk2.properties as below:
                   # Add the apr and channelJni to the list of handlers
                        handler.list=apr,request,container,channelJni
                        # The native libraries will be registered by JK2
                        apr.jniModeSo=inprocess

7. Comments part I, uncomments part II in server.xml

        Part I
                         <!-- commented out because we don't need a
standalone service -->
                            <!--Connector
className="org.apache.coyote.tomcat4.CoyoteConnector"
                                       port="9080" minProcessors="5"
maxProcessors="75"
                                       enableLookups="true"
redirectPort="9443"
                                       acceptCount="100" debug="0"
connectionTimeout="20000"
                                       useURIValidationHack="false"
disableUploadTimeout="true" /-->

                Part II
                        <!-- Define a Coyote/JK2 AJP 1.3 Connector on
port 9009 -->
                            <Connector
className="org.apache.coyote.tomcat4.CoyoteConnector"
                                       port="9009" minProcessors="5"
maxProcessors="75"
                                       enableLookups="true"
redirectPort="9443"
                                       acceptCount="10" debug="0"
connectionTimeout="0"
                                       useURIValidationHack="false"
        
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>

8. Startup Apache using below command:

        Apache -k start

9. Test using http://localhost/examples/, then shown:

                        Internal Server Error

Could you please give me some suggestion about the issue. Thanks a lot.
