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:
