Subject Tomcat 5.0.x (5.0.14), Apache 2.0.x (2.0.47), mod_jk2 (2.0.2) *doubt*
Date Thu, 30 Oct 2003 10:05:56 GMT
Howdy,

For those interested in integrating tomcat5 and apache2, I managed to get the
beasts working together in inprocess mode (tomcat's jvm started within the
apache). It is slightly different compared to tomcat 4.x case. I noticed that one
has to put additional jars on the classpath to prevent ClassNotFoundException
during classloading tomcat bootstrap classes and later on during tomcat startup.
(namely jmx.jar and commons-modeler.jar). However, I suppose we should avoid
placing anything below ${tomcat.home}/server and ${tomcat.home}/common
explicitely on the classpath.

Here is my (stripped-down) working workers2.properties file. Can anyone please
take a look at the contents of -Djava.class.path property. I am not quite sure it
"compatible" with current classloader architecture.

Is there's a better way to integrate tomcat 5 within apache 2? 

I also noticed a strange behaviour - tomcat when started (standalone as an nt
service or inprocess as described above) after being shutdown *inprocess* fails
to deserialize persisted sessions. I do not think it happened in tomcat 5.0.12.
Here comes the stdout:

Yep, you're right I should have reported it in bugzilla, but this case seems to
me way too complex. Can I have your comments on this, please?
