1. I don't think there's a problem with older versions of maven, I recommend you
just give it a try, you only need to change the maven version in prerequisites in the
parent pom to your version and try the build. If it works, let me know and I'll lower
the required maven version.
2. There is no problem with that, although this is currently not supported out-of-the-box
in the installer for example. You would simply need to replace how it is currently
configured for JBossAS with the tomcat equivalent. To get you started, this is what you
should do. If anyone wants to improve the installer script to support tomcat as well, I
would gladly accept the help ;)
If you run the installer for JBossAS, it generates and copies various artefacts. You can
get those to work on tomcat by doing:
copy the jbpm-gwt-console.war and jbpm-gwt-console-server.war to TOMCAT_HOME/webapps
rename jbpm-gwt-console.war to jbpm-console.war (so it shows up on
http://localhost:8080/jbpm-console http://localhost:8080/jbpm-console
rename jbpm-gwt-console.war to gwt-console-server.war (so it shows up on
http://localhost:8080/gwt-console-server http://localhost:8080/gwt-console-server
update TOMCAT_HOME/conf/tomcat-users.xml to include your users + roles
copy JBOSS_HOME/server/default/data/birt to TOMCAT_HOME/birt
copy h2.jar to TOMCAT_HOME/lib
update catalina.bat to set classpath variable jbpm.console.directory to the evaluation
resources dir (unless you use guvnor as process repository)
copy all necessary dependencies that are not in the default tomcat classpath to
TOMCAT_HOME/lib (or in the WEB-INF/lib folder of the gwt server war)

Hi Kris,
I'm able to deploy both the wars on tomcat/webapps and I'm able to start
application(jbpm-console) from browser.I've changed port to 9999 in server.xml
instead od 8080.Accordingly changed port in jbpm-gwt-core properties file.
So once I login to the application and when I click Process Overview,then I get
exception.It doesn't load the processes.
Here is the exception captured from the browser,since I didn't see any log folder in
tomcat as it was in Jboss default folder.
Error-
h1. HTTP Status 500 -
----

logs.
------------------------------------------------------------------------
Please let me know if any context.xml change/configuration or setting is
required,because it's not able to find data from the backend.
I believe we need to modify context.xml and put somewhere in META-INF. Any help would be
greatly appreciated.
Thanks,
Anand

Anand,
You still need to make sure all the jars that are needed are on the application
classpath. In this case, it's not able to find javax.persistence.Persistence, so that
means the jar containing the jpa classes is not in the tomcat lib dir (or the lib dir of
the jbpm console server war). Simply adding the jar in one of those two locations should
probably solve this (and you probably need quite a few others as well).
Kris

Hi Kris,
All required jars including persistence jars as mentioned below are there in
tomcat_home/lib folder and in gwt-console-server.war as well.
But still I get " Could not initialize stateful knowledge session:
javax/persistence/Persistence"
Infact I don't see any exception in server log and in humantask console window.
So it's related to testDS configuration and tranaction manager config for tomcat which
is causing that exception.
So where do we need to put testDS and configuration about datasource JNDI
(jdbc/testDS1)and transaction manager in server.xml file of tomcat?
