I am using oracle XE 10g . created a schema-activiti. I ran the create scripts . Updated the group,id,user information .  Added ojdbc jar in activiti explorer web app ->web-inf->lib. Then i modified db.properties file -

db=oracle
jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbcracle:thin:@localhost:1521:xe
jdbc.username=testactiviti
jdbc.password=activiti


i am able to connect to the oracle db and process definitions stored there. But once i restart my tomcat i am getting error as

Whats the issue in registering my db. Do i have to include any other details?

[raimana]

Tomcat is telling you that it has done "something" to prevent a memory a leak… Nothing wrong with Activiti… If anything it's the JDBC driver in question…

Edit:
No offense but I think what you need to do is use google first (that's the first result you get for that error…): http://stackoverflow.com/questions/3320400/to-prevent-a-memory-leak-the-jdbc-driver-has-been-forcibl...

i am not able to hit activiti web application after i restart my tomcat.. it is taking longer time to respond. It stops after deploying the samples..
