[Clustering/JBoss] - Re: Database with clustering
by bstansberry＠jboss.com
In most real world situations you are going to want a shared database. JBoss AS clustering doesn't somehow detect all database writes and keep non-shared databases in sync. If you are using JMS with persistent messages for sure you want a shared database.
The shared db can be a single point of failure. How you deal with that depends on the capabilities of your database.
Side note: The session passivation logic for clustered web sessions and clustered SFSBs use JBoss Cache's CacheLoader tech for persisting passivated sessions. JBC provides a CacheLoader implementation called JDBCCacheLoader that can write to a database (although by default the AS uses an implementation that writes to the filesystem.) *If* you decided to switch to the JDBCCacheLoader, that should use a datasource that *does not* use a shared database. That's an unusual config though.

[JBoss jBPM] - Hibernate problem using @PersistenceContext
by debasree08
Hi,
I wanted to get data from the jbpmDB(HSQL databse) stored. But when I use the @PersistenceContext I get the exception saying
1> java.lang.RuntimeException: Could not create Component: searchaction
2>Caused by: java.lang.IllegalArgumentException: @PersistenceContext may only be used on session bean or message driven bean components: searchaction
When I remove this then At runtime i get nullpointerexception when clicking the search button which is suppose to get data from database.
Please suggest what can be the problem.
THanks in advance.

So the application works just fine on Tomcat 5.5.
The version of JBoss I use is -jboss-5.0.0.GA. Just as I said, I configured any option I could find either in book - JBoss in Action, either in JBoss docs. about classloading issue. So what is the problem???
