[JBoss Portal] - ClassCastException accessing EJB3 from portlet

by cuoz

Hi all, I posted this to the EJB3 forum originally, but just tested my app using a plain WAR file and it works fine, so I think it is something related to classloading and my portlet... I'm trying to use my EJB3 application from a JBoss Portal portlet and getting the infamous ClassCastException. I have read all the wiki & other resources on classloading, etc, but have not been able to solve this one. Specifics are: JBoss 4.0.4GA, Portal 2.4-CR2, EJB3 RC8. I have packaged the ejb3 application and the portlet application in separate ear files (originally tried using just a war for the portlet), and have also tried scoped loader repositories. The portlet includes a jar file of only the client parts of my ejb3 application. I have JBossAS configured for call by value, etc. Here are application specifics: ClientEJB is an entity that implements Client interface ClientSessionBean is a SLSB ClientSessionLocal is the local interface to the session bean The method I am calling on the session bean is: Client createClient(String username, String password) It creates an instance of ClientEJB, persists it, and returns it as a Client interface. The call to the session bean works fine. I get the CCE when I try to use the returned object as a Client and not a ClientEJB. What should I be doing to make this work? Hopefully somebody already ran into this scenario and can help. Let me know if you need more information. Thank you in advance, Gary.

[EJB 3.0] - Re: ClassCastException calling EJB3 from Portal

by cuoz

Ok, I made a plain old WAR file (not a portlet) and deployed a simple JSP that uses my session bean just fine with the exact code copy/pasted from my portlet. So, it is probably a portal issue and not a EJB3 issue. I'll take my issue over to the portal forum and sorry for the wasted bandwidth. Gary.

[EJB 3.0] - Re: Tryed searching for this issue, but haven't found anythi

by RobJellinghaus

A very close reading of the Javadoc does yield some differences: get - Return the persistent instance of the given entity class with the given identifier, or null if there is no such persistent instance. Obtain the specified lock mode if the instance exists. Returns: a persistent instance or null load - Return the persistent instance of the given entity class with the given identifier, assuming that the instance exists. You should not use this method to determine if an instance exists (use get() instead). Use this only to retrieve an instance that you assume exists, where non-existence would be an actual error. Returns: the persistent instance or proxy I agree it's pretty subtle though. The Hibernate reference doc http://www.hibernate.org/hib_docs/v3/reference/en/html_single/#objectstat... is a little more clear: "Note that load() will throw an unrecoverable exception if there is no matching database row. If the class is mapped with a proxy, load() just returns an uninitialized proxy and does not actually hit the database until you invoke a method of the proxy." Cheers!

[JBoss Seam] - Re: Stateless Injection

by CptnKirk

Your url-pattern for your faces servlet mapping seems odd to me. Do you really have .jsp files that you get to via an .xhtml extension? foo.xhtml -> foo.jsp? How is userManagement.getUsers() getting called? Please show your view markup.

[JBoss jBPM] - JBPEL dependency on JWSDP

by rjain15

Hi I have installed and deployed the jbpel sar file on jboss 4.0.4 GA In order to run the examples I need to specify the JWSDP home. I believe JBOSSWS is the WebServices stack impl which is bundled along with the App Server. Do I still need to have the JWSDP? Why is this dependency.. regards RJ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3961058#3961058 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3961058

[JBoss Seam] - Re: <s:link view=

by d1g

I raised a related issue some time ago: http://jira.jboss.org/jira/browse/JBSEAM-216 This was to aid developers in creating nice looking URLs whilst still using Seam tags (for conversation management, etc.). I currently use an extended version of s:link (see issue above) along with url rewrites to create URLs which are prettier. It would be great if Gavin could take a look at s:link and consider these issues and the challenge of creating nice URLs.

Ok, silly question by me, since there are only persistence annotations. Thanks for the answers.

[JBoss jBPM] - Re: A timer associated to a process instance ?

by cpob

Look at the source code in CreateTimerAction and CancelTimerAction, they create and cancel timers programmatically.

- Yes, if you want Seam annotations to work you need the SeamInterceptor - Yes - Mmm i think that there is no Seam annotations in those entity beans. In which specific file are you wondering about the lack of Interceptor ?
