Hey everyone,
We have been trying to deploy drools-camel-server-5.3.x.Final.war from
droolsjbpm-integration-distribution-5.3.0.Final on WebLogic 10.3.3.
We hit a series of issues, of which I've opened up some issue tickets to
address:
1) strict web application container complains about web.xml (JBRULES-3403 -
https://issues.jboss.org/browse/JBRULES-3403) - web.xml needs to be
re-arranged to get it to work in weblogic 10.x.
2) There seems to be duplicate JPA persistence units
(https://issues.jboss.org/browse/JBRULES-3404)
I also experienced two other issues that I do not feel comfortable putting
on the issue tracker because they may be weblogic-specific:
3) When I tried to run a SOAP UI test on the drools server in Weblogic
10.3.3 I get this:

Seems to be two possible ways to solve this (have not tested these yet!)
Option One: Use axis.jar instead of saaj-impl.jar
1. add axis.jar file to bea class path
2. in startWebLogic.sh/cmd
set JAVA_OPTIONS=%SAVE_JAVA_OPTIONS%
-Djavax.xml.soap.MessageFactory=org.apache.axis.soap.MessageFactoryImpl
Option Two: Make a code fix to allow the saaj to function
Follow the below steps to resolve "UnsupportedOperationException"
a. Set classpath to latest saaj-impl.jar in startweblogic.cmd
b. Set the below 2 system properties in code.
System.setProperty("javax.xml.soap.MessageFactory","com.sun.xml.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl");
System.setProperty("javax.xml.soap.SOAPConnectionFactory","weblogic.wsee.saaj.SOAPConnectionFactoryImpl");
c. Note that the above 2 classes are available in the saaj-impl.jar which i
have used and set classpath in step1. If you are using different version of
saaj-impl.jar, set the exact "MessageFactory" and "SOAPConnectionFactory"
classes which are avilable in your saaj-impl.jar. (Just extract your
saaj-impl.jar and findout the exact classes).
Obviously we cannot expect Drools team to make any code changes with respect
to WebLogic, so I would imagine trying Step 1 is the best way to go.
4) The drools-camel-server.war’s test.jsp apparently runs an example that
uses a Camel route leading to a REST web service. This does not work for me
either off the bat:

Apparently the camel endpoint did not deploy at all, or something.
I'm wondering what of these issues are totally specific to WebLogic, and
which are just plain 'ole issues. Can anyone share their experiences or
expectations of using the drools camel server WAR within the various app
servers? How much are we expected to make custom changes?
