[Persistence, JBoss/CMP, Hibernate, Database] - Re: PB with wrapping my oracledatasource

by fcastillo.ec

Can you explain a little bit better how to do this... the DataSource that i get is from javax.sql and it doesn't have any method with the name getunderlyingconnection() I really need to use the features of Oracle, please let me know View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4127229#4127229 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4127229

[JBoss Seam] - Re: Seam 2.0.1GA : EJB Blockers with Weblogic 9.x/10.x

by lauerc

Hi folks, I'm currently working on the same issues because I'm forced to use BEA WebLogic Server, but like to continue to use JBoss Seam. I've tried to patch the current Seam version (2.0.1.GA) to get one step beyond the known EJB3 compiler problem. This was quite easy because only one single EJB interface is affected: org.jboss.seam.async.Dispatcher I've replaced the varargs definitions (Object...) by Object[], which is what the compiler creates anyway from it. For reasons of convenience, I've also created an method which completely reduces the method to the non variable parts. Here's an example: public T scheduleTimedEvent(String type, S schedule, Object... parameters); was turned into: public T scheduleTimedEvent(String type, S schedule); | public T scheduleTimedEvent(String type, S schedule, Object[] parameters); Maybe this is not as elegant as the varags solution, but it's a pragmatic way to suit our needs as I don't think BEA will fix the related problem in short. The next problem I stumbled into was a classloading problem related to another problem in BEA WebLogic 10.0 MP1. The server only works properly with it's own jsf implementation which is not deployed by default. It is packed into a war archive located at wlserver_10.0/common/deployable-libraries/jsf-1.2.war I tried to deploy this archive which failed, so I unpacked it and placed the included jars into the 'lib' folder below my weblogic domain root. After that I found out, that one jboss jar, which is needed to run the application under other application servers was missing in the seam distribution. I placed this file (concurrent.jar) into the folder lib below by test application subproject (examples/jee5/lib). After some more deployment descriptor related changes, which I will not describe in detail, the application seems to work at first. Unfortunately I detected runtime failures when playing around with the booking application. From time to time the application failed with an InvocationTargetException. After hours of code analyzing and debugging, I found out that the problem has to be a side effect of different EJB lifecycle implementation in WebLogic Server compared to JBoss AS (I don't know which behaviour is wrong or right, and I won't judge it here). Actually the method postConstruct(...) of class org.jboss.seam.intercept.SessionBeanInterceptor seems to rule the initialization of this interceptor. This method seems to be called before any call of aroundInvoke at JBoss AS. On WebLogic Server this is different. As a result of this sometimes the injection field or method invoking for a specific object is executed using the reflection fields and methods of different component classes. To fix this problem, I've copied the initialization calls from method post construct into the method aroundInvoke to make sure that it is called prior to the actual invocation. After this change the booking demo seems to work perfectly. I've packed all source changes and the missing jar file into one zip archive and will post it into this thread. To use this, simply extract it below the exploded distro archive and rebuild first seam and then the jee5/booking demo.

[JBoss jBPM] - Is it possible to undeploy BPEL processes?

by meghanai_99

Hello, Is there an API to undeploy BPEL processes from JBPM engine? I know there is no webservice to do that right now but we can add such webservice if there is underlying infrastructure available. Thanks, Meghana.

Yes. That's exactly what was happening. I will create separate topic for my other question.

[JBoss jBPM] - Re: Is jBPM-BPEL GA backward compatible to beta 3?

by alex.guizar＠jboss.com

I get it now. Due to the renaming, the old BPEL_SCRIPT table and the foreign keys referencing it still exist. When you insert a new record in BPEL_TO, the constraint is violated because the query is inserted into BPEL_SNIPPET, a. o. t. BPEL_SCRIPT. Thanks for figuring it out. I'd prefer to discuss undeployment on a separate topic.

[JBoss jBPM] - Re: Is jBPM-BPEL GA backward compatible to beta 3?

by meghanai_99

Thanks Alex, I got our deployment module working with fresh GA and also upgraded to GA engine. I had to drop 2 foreign keys, FK_TO_QUERY and FK_ALIAS_QUERY to make the upgrade work. But it is looking good so far. The problem was that Snippet.hbm.xml uses BPEL_SNIPPET as its table now and not BPEL_SCRIPT. While we are at this discussion, can you provide me some information about how I can undeploy BPEL processes? Is there any API to do that? Do you prefer separate thread for this question?

[JBoss Seam] - Seam Design Question

by tony.herstell＠gmail.com

1/ I have a number of resources say: Enum {A,B,C,D,E} I have "Hour Slots" when they are being used. I have users that can book the resource. I have created a Conversational Bean to select the resource(s) and now want a show the current bookings (for certain bookings this will be on same page using Ajax as only can book upto 14 days in advance)... so the user can book into slot(s) that are free (this gets more complicated when I have to auto-fit complicated bookings but we won't go there). My Proposed Solution: Create a Session Scoped bean (ResourceAllocation) with some members: AHourSlots BHourSlots CHourSlots etc. I chose Session as the site won't be hammered so I can afford a few database hits (and storage use) when new users hit the site to book a resource. (I can always move over to Application if need be later)... For now I somehow feel safer (VMS days) to throw away the resources when the session dies as any bugs in keeping it updated are localised to the max duration of a session ;) I want in my .xhtml page to just have access to the coped variables like: AHourSlots BHourSlots CHourSlots etc. And I believe that if I have them in ResourceAllocationImpl anotated with @Factory(scope=ScopeType.SESSION, value="AAllocation") then this would do the trick. Is this course likely to cause problems. (prefer not to have things in components.xml if I can help it as too disjoint from the code). 2/ As the page is ajaxified I end up with the booking all on one page, BUT I want to force the user to log in (or register) before the booking is saved and I cant see a way to do this unless I force them to go to a page which has a loggedIn guard (me thinks a confirmation page)... Is there a way programatically to do summat like this: public String saveTheBooking() { String nextNavigationPort = null; if (!loggedIn) { seam.core.nestToLogin(); } if (loggedIn) { // Park the sucker under the users name em.persist(booking); nextNavigationPort = "home"; return nextNavigationPort; } else { // Message the user to say refused to login so no-way-hozay ... } } This would be kinda useful for parking the booking part-through (as its quite complicated!)

You can still control how the web service is deployed if you like. To do so, provide your own web.xml in the process archive and set the URL pattern on the servlet mapping elements to whatever value you like. To control the context root, either provide a jboss-web.xml descriptor in the process archive or take advantage of the following fact. Say your process archive is called myprocess.zip. The generated web module will be called myprocess.war. In absence of jboss-web.xml, the context root will be myprocess.

[JBoss Seam] - Re: When to use @PersistenceContext vrs @In EntityManager (S

by reind

I've also noticed that if I find an entity using a EJB PersistenceContext EM, then I get LazyInitializationExceptions when trying to fetch a property of that entity in another bean that uses the SMPC EM. The only way I've found around this is to re-fetch the entity using the current EM. This seams highly non-ideal. What's the proper approach in this case? If I don't want to start a long-running conversation in an SFSB then the only way to keep the em session going across multiple invocations is by using the EJB3 Extended PC, but then these entities are non-transferable to other seam components (where they'll produce LIEs). It seems one must use all Extended PC or all SMPC or refetch the entity with the current EM: entity = em.find(Foo.class, entity.getId()); Or am I missing something?
