How to force the container to call ejbStore()

[maha laxmi]

ictx = new InitialContext();
home = (EmployeeEntityHome)ictx.lookup("EmployeeEntityBean");
remote = (EmployeeEntity)home.findByPrimaryKey(new Long(EmployeeMaster.EmployeeReferenceNo));
remote.setEmployeeMaster(EmployeeMaster);

in the entity bean it will call setEmployeeMaster method where i will set dirtyflag = true;now presently what happened is after all methods are executing only (before transaction is commit..) container is calling ejbStore();

when i setEmployeeMaster i want to force the Container to call ejbStore();Is there any options in JBoss4?
