How to rolledback the transaction in ejbStore()

Question

we are using mvc-2 architecture.when i want to modify the employee details what we r doing is from controller it will goes to modifyEmployee method in sessionbean.as u can see in code we will setEmployeeMaster inturn it will call setEmployeeMaster in Entity bean ;we r using EJB1.1;
i am checking whether sizes of empcharges and deptcharges does not equal then throw exception and total transaction should be rollback.
At the time of reterving the count of two tables even data is not inserted in two tables in ejbStore() because ejbStore will be called by the container;after executing full methodthen only container is calling ejbStore where i am inserting data in two tables;
my requirment is i have to check whether in two tables any mismatch is going ;
how can i write this in this type of scenario?but while creating employee details i have to put same condition where ejbCreate will be called at that time transaction is rolledback.(when i say home     = (EmployeeEntityHome)ictx.lookup("EmployeeEntityBean");
remote     = (EmployeeEntity)home.create(); container is calling immediately ejbCreate);
in this case container is not calling immediately ejbStore when i say remote.setEmployeeMaster(employeeMaster);
i have written Pseudo code may be some errors are there;
Session bean
modifyEmployee(EmpMaster empMaster) thrpws MismatchException
try
*************other business processes******************
ictx     = new InitialContext();
home     = (EmployeeEntityHome)ictx.lookup("EmployeeEntityBean");
remote     = (EmployeeEntity)home.findByPrimaryKey(new Long(empMaster.empNo));
remote.setEmployeeMaster(employeeMaster);
*************other business processes******************
query1="select count(*) from empcharges where empno='*****'"
query2="select count(*) from deptcharges where deptpno='*****'"
rs=stmt.executeQuery(query1);
rs1=stmt.executeQuery(query2);
if(rs.next)
int cnt1=rs.getInt(1);
if(rs1.next)
int cnt2=rs.getInt(1);
if(cnt1 != cnt2)
flag =true;
if(flag)
throw new MismatchException("mismatch exception ");
catch(Exception e)
ctx.rollBackOnly();
EntityBean
public void setEmployeeMaster(EmployeeMasterDOB employeeMasterDOB)
          this.employeeMasterDOB = employeeMasterDOB;
          isDirty = true;
     public void ejbStore()     throws javax.ejb.EJBException
          try
if(isDirty)
                    isDirty = false;
                    EmployeeMaster EmployeeMasterDAO = new EmployeeMaster();
                    EmployeeMasterDAO.store(employeeMasterDOB);
               catch(Exception ex)
                    if(logger.isErrorEnabled())
                         logger.error(FILE_NAME+"[ejbStore()] -> "+ex.toString());
          throw new EJBException(ex.getMessage());
     EmployeeMasterDAO
     store(employeeMasterDOB)
               data will be inserted in empcharges and deptcharges tables...
     }

I have unchecked data control in department BTF. Now i can able to commit only employee form, Unable to commit department form ....
My req is i have two form employee and department m using BTF in two diff tabs. I want the transaction must be independent for both BTF in same application module..
Is this work when you put commit button on page inside BTF ?
If you want to commit particular BTF with commit button placed outside of BTF, you will need to somehow invoke commit operation in BTF.
For example, you can use contextual events( ADF: (re-)Introducing Contextual Events in several simple steps</title> //<title>AMIS Technology Blog &am…)
