Subject Re: Question about JK2, Apache2 and TC 4.1.12 with jdk1.3.1_02
Date Sat, 26 Oct 2002 01:06:22 GMT
Well,

If you want to use jni and have Apache startup Tomcat you're going to have 
to change some things in both of your config files.  You should really 
take a look at the new docs at 
C:\build\jakarta-tomcat-connectors\jk\build\docs\jk2\confighowto.html.

First:  apr.jniModeSo=some_path is the unix way to jni.  For Win2k you just need "inprocess".

Second:  You have almost everything needed to start Tomcat in-process 
commented out in wk2.prop.  Did you intend to do this.  It's almost as if 
you meant to start TC manually, or as a separate process?

I send you my conf files they are both pretty vanilla.

Here's my jk2.properties file:

Note:  At one time you also needed a, channelJni.disabled = 0, statement. 
Don't know how old your version of jk2 is so you might need it.

# Start jk2.p ######################

# 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

# End jk2.p ######################

Here's my workers2.properties file: 

Note:  My variable for ${serverRoot} did not work so I just hard coded my 
path to Apache home where it was needed.
Note:  I'm giving you the whole wk2.p file here.  Everything is not 
needed.  To get jni working you only need all the sections that deal with 
jni and of course your uri mappings, but you may gain some insight from 
everything else.

Hmmm,

Never tried to make it work with an old version of JSDK.  It should still
work with JSDK 1.3.1, but I haven't done it.

Are you trying to start it up in process?  jkjni.dll should not be
required for Apache.

Really I can only give you guesses if you don't post your configs.  I'll
need jk2.prop..., worker2.prop..., etc.

        cc:
        Subject:        Question about JK2, Apache2 and TC 4.1.12 with
jdk1.3.1_02

I have been struggling with JK2 to link Apache2 and TC 4.1.12 using JDL
1.3.1_02 on a Win2K system

All the docs and how-tos that I have found all talk about JDK1.4. And
using
JDK1.4 it does seem to work. However I have to use JDK 1.3.1_02 and cannot
get it running.

I have put mod_jk2.dll in Apache2\modules, and have jk2.properties in
%CATALINA_HOME%\conf

When I start up TC I get this:

[INFO] Registry - -Loading registry information
[INFO] Registry - -Creating new Registry instance
[INFO] Registry - -Creating MBeanServer
[INFO] Http11Protocol - -Initializing Coyote HTTP/1.1 on port 8080
Starting service Tomcat-Standalone
Apache Tomcat/4.1.12
[INFO] Http11Protocol - -Starting Coyote HTTP/1.1 on port 8080
[INFO] JkMain - -APR not loaded, disabling jni components:
java.io.IOException:
no jkjni in java.library.path
[INFO] JkMain - -Jk running ID=0 time=0/140  config=C:
\Java\jakarta-tomcat-4.1.12\conf\jk2.properties

I have got the jkjni.dll file too, but no matter where I put it, I get the
same error.

What have I forgotten/omitted?

Any help gratefully received.
