Hi @ all, i have a Problem with Lock/Unlock a Node in a XA Environment
The Test Case : -------------------------------------------------------------- UserTransaction utx = new UserTransactionImpl(superuser); utx.begin(); Node n1 = testRootNode.addNode(nodeName1); n1.addMixin(mixLockable); n1.addMixin(mixReferenceable); testRootNode.save(); String uuid = n1.getUUID(); utx.commit(); Session other1 = helper.getSuperuserSession(); utx = new UserTransactionImpl(other1); utx.begin(); n1 = other1.getNodeByUUID(uuid); Lock lock = n1.lock(true, false); String lockToken = lock.getLockToken(); //other1.removeLockToken(lockToken); utx.commit(); //other1.logout(); Session other2 = helper.getSuperuserSession(); utx = new UserTransactionImpl(other2); utx.begin(); other2.addLockToken(lockToken); n1 = other2.getNodeByUUID(uuid); n1.unlock(); -> Throws Exception -> Node not locked by this Session ! utx.commit(); ------------------------------------------------------------ 1. In the first Transaction i will create a node 2. In the second Transaction i will lock the node 3. and in the third Transaction i will remove the lock from the node Info: we are using jackrabbit with the JCA Connector and so i will get a JCASessionHandle to the underlying XASession. Now i have some Problems :-) ... A Node is not unlockable while the Lock-Creating-Session will be logged out or the LockToken will be removed from the Lock-Creating-Session. In a JCA Environment the session.logout() will be delayed till the JCAManagedConnection will be destroyed from the container so a logout could not be guaranteed. Removing the LockToken from the Lock-Creating-Session in a XAEnvironment will end up in a empty Method XAEnvironment.removeLockToken() so in the referenced LockInfo Object is still the LockOwner the Lock-Creating-Session. I don't know the best solution. We can set the LockHolder to null but then we must change some code in LockMangager.isLockHolder because this method checks if the given Session is equals the LockHolder and this is not the case with a non session scoped lock. What do others think ? greets claus
