Re: OpenEJB/Tomcat 6 manual integration help

Wed, 15 Apr 2009 10:43:02 -0700 

Hi David,
I couldn't get the installer to work in my environment. It came back saying it couldn't find my catalina.sh file. Not sure why, but that's OK, as my Tomcat installation is mildly tweaked so I can keep all (or as many as possible) of the Tomcat distribution files "stock". And so a manual integration is vastly preferable to me. 


By Reading The Friendly Source for Installer.java I figured out that I needed 
the Tomcat-specific loader JAR file and Listener classname.



Also figured out the catalina.sh addition, and put that in my environment 
setup script (i.e. set the -javaagent in JAVA_OPTS prior to calling catalina.sh.)



All I have left to do is extract the openejb.conf and logging.properties files 
into my $CATALINA_HOME/conf (sourced, respectively, from default.openejb.conf 
and logging.properties in the openejb-core-3.1.jar file.)



For the benefit of Unix hack SA dinosaurs like me, it would be great to have a 
documented/supported recipe for a manual integration. :-)


Thanks!

Hi Zach,


Those directions should probably be deleted.  Simply deploying the 
openejb.war and then running through the "installer" link at 
http://localhost:8080/openejb/ is definitely the best approach.  It will 
do the installation steps for you and tell you what it's doing.



In 3.1 we updated the integration a bit and it looks like we forgot to 
update that page to reflect it.  Add the openejb-tomcat-loader-3.1.jar 
to $CATALINA_HOME/lib and change the listener classname from 
"org.apache.openejb.loader.OpenEJBListener" to 
"org.apache.openejb.tomcat.loader.OpenEJBListener"


Definitely let us know if you have any more issues.

Hello,


I am getting a ClassNotFoundException for 
org.apache.openejb.loader.OpenEJBListener on Tomcat startup after 
copying the openejb-loader-3.1.jar into $CATALINA_HOME/lib and adding 
the Listener element to the server.xml.


I am using Tomcat 6.0.14 with Java 1.6.0_05 on Solaris 9.


I am trying to manually integrate as per 
http://openejb.apache.org/manual-installation.html, since the 
installer does not seem to like my tweaked-for-my-own-purposes Tomcat 
installation.


openejb.war downloaded and expanded to $CATALINA_HOME/webapps/openejb:


{zr129649}

openejb-loader-3.1.jar copied to my $CATALINA_HOME/lib:

-rw-r--r--   1 tdmsadm  dba        34063 Apr 14 00:02

and the Listener element added to my server.xml:


{zr129649} 
phys-lsu-hadbms-tst-01:/local/DATA/SUNWtatc5/apache-tomcat-6.0.14

576 > cat conf/server.xml

I'm no Java or Tomcat guru (I'm getting this setup for our sw 
developer), but to my knowledge, I do not need to do anything explicit 
to get Tomcat to "see" the .jar files placed in $CATALINA_HOME/lib.


Any advice/suggestions greatly appreciated.
