Bug 779881 (SOA-2240)

Workaround Description: turn of DEBUG of org.jboss to debug issues.
recompile classes when issues occur, and remove etc classes from classpath.
project_key: SOA

Take the sample quickstart business_ruleservice_ruleAgent and modify it to use BRMS/Guvnor as supported in SOA-P 5 with BRMS/Drools 5. During the 'ant runtest' the console log will display an exception related to the localCacheDir location not being available, although the location is a directory. 

However, if the localCachedir property is removed from the brmsdeployedrules.properties file. It will now complain the the classes have serial ids which do not match. 

After the Serial ID issues are resolved the localCachedir property can be added back. The localCachedir error hides the real issue. In addition, these exceptions will not be discovered without full debug turned on at the log4j level. Here are the steps of the test case: 


1. Modify the brmsdeployedrules.properties file to be: newInstance=true url=http://localhost:8180/brms-console/org.drools.guvnor.Guvnor/package/insuranceconfig/LATEST localCacheDir=/tmp/ruleAgent/cache poll=30 name=insuranceconfig 

2. Add the Driver.class and Policy.class to a jar and add this to an insuranceconfig package in BRMS.

3. add the orginal.drl to BRMS 

4. ant deploy from quickstart folder business_ruleservice_ruleAgent 

5. Change log4j.xml to DEBUG level for org.jboss 

6. start server: run.sh

 7. ant runtest 

8. The following exceptions will be found in the console:

10. restart server. 

11. Error will mention serial ids now. 

12. Recompiles will solve the issue and removal of extra class jars, etc.

 Exception handling needs to be available for other than debug for this issue and improper errors are found.
