[JBoss Seam] - WebSessionContext.flush causing out of memory
by jarkko＠jab.fi
Hello,
A change (from non impl to the current copy-all) in WebSessionContext.flush is causing out-of-memory experiance in my portlet environment (with the special naive PortletSessionImpl).
With the flush below, 1000 Mb of memory consumed in 20 clicks in seam app, with the flush commented out no problem.
This is likely caused by the PortletSessionImpl which simply sets everything both in APPLICATION and PORTLET scope.. Btw i used the Jhat (included with JDK6) too to track this one down, pretty neat tool, now that's included with the JDK6. http://weblogs.java.net/blog/jfarcand/archive/2006/02/using_mustangs.html
The names of attributes were very very long:
javax.portlet.p.tc3_konseptimittaus_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3_konseptimittaus_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3_konseptimittaus_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3_konseptimittaus_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3_konseptimittaus_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3_konseptimittaus_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3_konseptimittaus_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3_konseptimittaus_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?javax.portlet.p.tc3Portlet_kohteen_valinta_WAR_TrueConcept_LAYOUT_PRI.1005.6?org.jboss.seam.CONVERSATION#3$tc3EntityManager
This might indicate that there're some pretty weird namespace related problems when running on Portlets.

[JBossWS] - WS and Transactions

Using Web Service and Transactions annotations at the same time in my class is causing the following problem:

So if I remove the transaction annotations from my class, then everything works as expected. I am using JBoss AS 4.0.4GA, with AOP 1.5.1GA, WS 1.0.3GA, and JDK 1.5.0_05.
Any ideas?
