[JBoss Seam] - Re: Spring and Seam managed persistence contexts

by youngm

Oh, ya. Seam uses a thread local to get it's "Context" and then uses the various scopes in that context to determine the actual values in the scopes. If you wanna get into much more detail on how Seam manages it's scopes it would probably be best to look at the code. I think the key here is that this integration lets Seam do it's thing and Spring do it's thing and the actual connection between the 2 is quite loose. So if you wanna use a Seam managed persistence context you just need to make sure Seam is set up correctly for the Context of that call into the spring singleton and it will just work. The spring seam integration also contains code to attempt to automatically set up a Seam Context and scopes it in a spring transaction in the case of a non web request originated call into spring.

[JBoss Seam] - Making Spring beans into Seam components via annotations?

by rhasselbaum

Is there any way to make a Spring bean into a Seam component using annotations? All of the examples in the Seam reference doc assume the Spring beans are configured via XML, but newer versions of Spring don't require that. Thanks.

[JBoss jBPM] - 2nd level cache management

by nlebas

I'm looking for a way to tune the second level cache of jBPM (3.2.2) according to my needs. jBPM internally configures the cache concurrency strategy for several collections as "nonstrict read-write", while I need them "read-only" (to avoid prohibitive synchronization cost and eventual errors in my highly concurrent clustered environment). I tried to setup the properties "hibernate.ejb.collectioncache.*" but jBPM's internal configuration actually overrides them. Why has the cache concurrency policy to be coded inside the product ? What is the best way to set it read-only ? Should I rewrite jBPM's mapping files ?

[JBoss Seam] - Re: Spring and Seam managed persistence contexts

by rhasselbaum

Right, but I'm just wondering how (internally) the Seam-managed factory knows which session to return, given the fact that the object holding the factory (i.e. the DAO) is shared among all threads/conversations. Does the conversation state get put into thread-local storage and the Seam-managed session factory looks it up from there? I guess I could just look at the code. ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4116490#4116490 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4116490

[JBoss Seam] - Re: ejb + seam from swing gui

by pete.muir＠jboss.org

Yes - it just needs implementing. We need to formalise the API for hooking in clients (thus meaning all the client needs to is provide a conversation id to propagate conversations).

[Installation, Configuration & DEPLOYMENT] - Trouble with images outside of JBOSS_HOME...

by Spuds

I have 2 different physical servers, one is development, one is QA. The DEV server application is in /apps/jboss/server/ The DEV images are in /usr2/dev/web//images1 The DEV server works fine. The QA server application is in /apps/jboss/server/ The QA server images are in /usr2/qa/web//images1 The QA server won't serve images at all-- even if directly called by URL. I get the following error... HTTP Status 404 - /images1/nav/button_regular_go.jpg -------------------------------------------------------------------------------- type Status report message /images1/nav/button_regular_go.jpg description The requested resource (/images1/nav/button_regular_go.jpg) is not available. DocumentRoot is set to /usr2/qa/web/ (in mod_jk.conf) Permissions on the files are correct. My VirtualHost blocks in mod_jk.conf on both servers are identical. If I use rewrite rules to have the QA server pull images from the DEV server, it works fine. :( Both are JBoss 4.2.0 servers. I have been working on this for a long time and I'm kinda at wit's end. Can anyone give me a pointer on where else I should take a look? Thanks in advance for all the hard work of the moderators and those that answer our questions day to day!

[JBoss Seam] - Re: pageflow and parameters transmition

by gazadonf

Ok, after serveral tries, it works... I notice that i have to declare nox parameters in the departure page définition instead of the arrival page when using a pageflow definition, like this: | <page view-id="/project/ProjectList.xhtml"> | <param name="theProject" value="#{projectHome.projectId}"/> | </page> | Is it normal?

[JBoss Seam] - Re: Instances get lost - strange behavior in conversational

by marcelkolsteren

I encountered the same problem in my J2EE application, which uses Seam 2.0.0.GA. It is caused by a bug in JBoss/Seam. See the JIRA issues JBSEAM-2214 and JBSEAM-2224. I got rid of the problem by installing the fix (EntityBeanList.java version 1.6).

[JBoss Seam] - Re: Propagation of Persistence Context in Seam

by pete.muir＠jboss.org

The scope is conversation. The same Persistence Context will injected by @In (or via programmatic lookup) during the lifetime of that conversation. If you inject via @PersistenceContext, it isn't a SMPC.
