Re: Problem at geronimo boot

Hi kevan, sorry i could not answer before. No, the structure is the usual one EAR:   META-INF/   War     WEB-INF     lib       hibernate.jar       spring.jar(s) Viet, may be that you are not really using the transaction manager of the container ? may be you are using just some queries in autocommit mode or read-only mode ?

I'm guessing it's something like: EAR:   META-INF/   hibernate.jar   spring.jar(s)   War1   War2 In Geronimo, each of your WARs will have a unique ClassLoader. >From your stack trace, It looks like somebody (your apps, spring, hibernate, or acegi) is attempting to share Hibernate interfaces between two different WAR classloaders (i.e. assuming that there is a single instance of Hibernate classes/interfaces). Moving your hibernate.jar file into the lib/ directory of your EAR may fix your problem (do not move the spring jars into lib). So, your ear layout would look like: EAR:   META-INF/...   lib/hibernate.jar   spring.jar(s)   War1.war   War2.war Let us know how this works. It sounds like Viet has a basic hibernate app working. So, /me crosses fingers... --kevan
