Transaction roll back in session bean

Hi

I've a session bean to compute and create complex report. It stores data in 3 tables, and should be completely rolled back when any exception occurs. It's sth like this:

public void createReport() {
reportId = reportEntityBean.create(...).getReportId();

for(...)
createSubReport(reportId, ...); /* invokes some calculations and subreportEntityBean.create(reportId, ...); */

for(...)
createReportItem(reportId, ...); /* invokes some calculations and reportItemEntityBean.create(reportId, ...); */

checkIsValid();
}

Ok, this code if everything is ok, should create entities in 3 tables. But I want also everything to be rolledback if any exception in this method or methods invoked by it occurs. For example, if report entity is already create and exception in subreportEntintyBean.create method is raised, I want to remove created report. Unfortunately it's not working as expected. In ejb-jar.xml I have set attributes of the methods:

createReport as Required
createSubReport, createReportItem, checkIsValid as Required (also tried with Mandatory)


please help.

If one throws an application exception from the method with defined attribute of rollback=true then rollback takes place (EJB 3.0 )
OR
Call the method SessionContext / setRollbackOnly(). This flags that the method transaction should be rolled back.


Could you please check if this works with EJB 2.1 for your case as well?

I enclosed all operations in method createReport into try catch block, and I invoke setRollbackOnly() in each catch block. Unfortunately transaction is not rolled back.

Check your JDBC connection. If you get a JDBC connection from a plain DataSource or directly from the JDBC driver, it will not participate in the EJB container transaction.
