Subject Unable to connect Apache 2.0.48 to tomcat using JK2 Connector an d JNI.
Date Fri, 02 Apr 2004 19:13:19 GMT
Hi,
	I am trying to connect tomcat 5.0 and Apache 2.0.48 through JK2
connector using JNI on Windows 2000. The channel.jni:jni init is failing.


I greatly appreciate any help with this.


Thanks,
Sreeni

Following are the errors from the log file mod_jk2.log

------------------------------------------------------------------



Followed the steps below:
	

STEP 1: Installing mod_jk2
--------------------------
1. Copy the mod_jk2.dll into <APACHE_HOME>/modules directory.
2. Add the following line to httpd.conf
	LoadModule jk2_module modules/mod_jk2.dll

#I also tried installing and configuring jkjni.dll in <APACHE_HOME>/modules.
That did not help either.



STEP 2: Configure <TOMCAT_HOME>/conf/server.xml
-----------------------------------------------
Disable the default connector on port 8080

Enable the AJP connector on port 8009.


STEP 3: <TOMCAT_HOME>/conf/jk2.properties
-----------------------------------------

channelJni.disabled=0

STEP 5: Start up
----------------

Start tomcat first
Wait until the instance is started.
Start apache.
