Using TransactionManagementType.BEAN sometimes gives javax.persistence.TransactionRequiredException depending on the components on the xhtml page ------------------------------------------------------------------------------------------------------------------------------------------------- Key: JBSEAM-3468 URL: https://issues.jboss.org/browse/JBSEAM-3468 Project: Seam 2 Issue Type: Bug Components: EJB3 Affects Versions: 2.0.2.SP1 Environment: Windows XP, JBoss AS 4.2.2 Reporter: Susanne Jarl I have a SLSB: @Name("statService") @Stateless @TransactionManagement(TransactionManagementType.BEAN) public class StatServiceBean implements StatServiceLocal { @In EntityManager entityManager; @Resource SessionContext ejbContext; public void generateStat() { Query query = entityManager.createNativeQuery( "INSERT INTO x" + "SELECT y, :currentDate, count(distinct(ip)) AS number " + "FROM z" + "WHERE datetime BETWEEN :currentDate AND :currentDatePlusOne " + "GROUP BY (x1) " + "ORDER BY number desc ").setParameter( "currentDate", calCurrent.getTime()).setParameter("currentDatePlusOne", calCurrentPlusOneDay.getTime()); // Save to database. Create manual transaction since the built in only works for 5 minutes. UserTransaction transaction = ejbContext.getUserTransaction(); try { transaction.begin(); query.executeUpdate(); transaction.commit(); } catch (Exception e) { try { log.error("Transaction failed when updating stat. Try rolling back.", e); transaction.rollback(); } catch (Exception exp) { log.error("Transaction failed roling back.", exp); } } } I have a xhtml page with components calling the generateStat method and depending of what components are on it this code works or it gives me a TransactionRequiredException. This does not work: <s:link action="#{statService.generateStat}" value="Update stat" /> This does not work "alone": <h:form><h:commandButton action="#{statService.generateStat}" value="Uppdatera sidvisningsstatistik" /></h:form> but if you add for example: <f:subview id="subcriberView" rendered="#{userAdmin.subscriber != null}"> </f:subview> so you have both the form with the button and this subview component that calls userAdmin which is a stateful session bean and "subscriber" is just a property, then it works! The sql insert statement is run and the database gets updated and I don't get any exceptions. So I guess this must be a bug! It seems like you need a call to some SFSB in the same request in order to get the manual userTransaction begin and commit to work. But in the case with <s:link> then it does not help to add the f:subview code so I don't know... In my components.xml I have this code: <transaction:ejb-transaction /> but if I remove it, there is no difference.
