>From what you post, it does not look like the caller is in a transaction.
This causes:
agent = home.findByPrimaryKey( new AgentPK(id) ); //to start and complete a new
transaction for the call
eaf.setId( agent.getId() );//to start and complete a new transaction for the call
:
Collection engines = agent.getSearchEngines();//to start and complete a new
transaction for the call
If the caller is in a a Tx, all the entity bean methods will be executed as part of
the existing Tx. The most common way to acheive this is to have your struts Action
call a SSB (Session Facade) that has trans-attribute=Required, and to use a data
transfer object to pass the values from the facade back to the caller.
An alternative would be to manage the transactions yourself by using User
transactions, along the lines of:
UserTransaction tx = null;
try
{
InitialContext ctx = new InitialContext();
tx = (UserTransaction) ctx.lookup("UserTransaction");
tx.begin();
//Do your stuff
if (tx.getStatus() == Status.STATUS_ACTIVE)
{
tx.commit();
}
return table;
}
catch (Exception e)
{
if (tx != null) tx.rollback();
}
