[JBossWS] - Re: If I deploy more than one webservice I get

by avbentem

Even when deploying only a single web service, this error may also be caused by some left-overs after refactoring without properly cleaning up. I changed the name of my service using Eclipse, which left the old compiled classes in various exploded archive folders. Those were then still copied to, and loaded by, JBoss. This resulted in multiple services (same implementation with different class names) within the same application, and thus yielding the "org.jboss.ws.WSException: Multiple context root not supported" error. My stupid mistake, of course...

[JBoss Seam] - Re: Howto handle LazyInitializationException

Hi Thierry, Have you read about the extended persistence context? If not, this is where your answer lies http://docs.jboss.com/seam/1.2.1.GA/reference/en/html/persistence.html Using a conversation-scoped SFSB with an extended persistence context will solve your problem. Daniel.

[JBoss Seam] - Howto handle LazyInitializationException

by thierry.rietsch

Hello I have a problem with lazy loading and need a workaround. I have an Entity called SoftwareInventoryObject which contains a Collection of SoftwareInventoryObjectParts. | class SoftwareInventoryObject { | // other fields | List<SoftwareInventoryObjectPart> parts; | | // Getter & Setter | } | Additionally I have a EJB3 Bean SoftwareObjectSearch which searchs in the database for the above mentioned SoftwareInventoryObjects. | class SoftwareObjectSearch { | // other code | | @DataModel | List<SoftwareObjectPart> inventoryObjects; | | // other code | } | To view the result I have a facelet which contains a <h:dataTable>. Now I would like to display each of the SoftwareObjectParts too therefor I have a nested <h:dataTable> in the facelet. | <h:dataTable value="#{inventoryObjects}" var="sio" rendered="#{inventoryObjects != null}"> | <h:column> | <h:dataTable value="#{sio.parts}" var="siop"> | <h:column><f:facet name="header">Name</f:facet> #{sio.name}</h:column> | <h:column><f:facet name="header">Type</f:facet> #{sio.type}</h:column> | <h:column><f:facet name="header">Barcode</f:facet> #{sio.barcode}</h:column> | <h:column><f:facet name="header">Manufacture</f:facet> #{sio.manufacture}</h:column> | <h:column><f:facet name="header">Distributor</f:facet> #{siop.distributor}</h:column> | <h:column><f:facet name="header">Order Number</f:facet> #{siop.orderNumber}</h:column> | <h:column><f:facet name="header">Price</f:facet> #{siop.price}</h:column> | <h:column><f:facet name="header">Version</f:facet> #{siop.version}</h:column> | <h:column><f:facet name="header">Action</f:facet> link</h:column> | </h:dataTable> | </h:column> | </h:dataTable> | Now when I run a facelet I get a Lazy Initalization Exception for the siop, the SoftwareInventoryObjectPart. This makes sense to me, because I access a collection which is not eager loaded, after the initial Hibernate session was closed. My question is now, how can I avoid such an exception? What is a nice workaround. If you need any further code please let me know. Thanks for all the answers in advance.

Great, I indeed just received the JIRA notifications. Do the efforts to create a new patched 3.1.4 version imply that jBPM 3.2 will probably not make it into Seam 1.3?

[JBoss jBPM] - Re: cannot read process variable from other thread

by clandestino_bgd

Hi, actually it did not help. Like stated at http://www.jboss.com/index.html?module=bb&op=viewtopic&t=108409, since 2 threads are in game: JMS and JBPM then will join the race, so sometimes it will pass, sometimes won't. Actually that made a big problem to me, so I would strongly advice to either use XA transactions like mentioned or to redesign process and avoid using JMS, which I did at the end.
