Synchronization in BMP

[cleconte]

Hi,

I have developped an entity bean (BMP), ejbStore and ejbLoad call the data base with 'update' and 'select'.

I wonder if the engine JBoss calls these methods for synchronizing the bean with my data base ?
In fact I believe that I must manage the synchronization myself in my business method.


I research an explication about synchronzation in JBoss.

best regard.

The EJB-Container will call ejbLoad and ejbStore. You should have a look at the EJB specification, it contains object interaction diagrams that show exactly when these methods are called.

ejbLoad and ejbStore are invoked according to
the ejb spec.

The default config for BMP in jboss is
commit-option A, but for CMP it is commit-option B
See standardjboss.xml

A means load once (unless flushed from the cache)
B means reload every transaction
