Subject Re: OpenEJB/Tomcat 6 manual integration help
Date Wed, 15 Apr 2009 16:18:10 GMT
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.

-David
