[Security & JAAS/JBoss] - getCallerPrincipal throws NullPointerException

by sunnygrass

I'am new in JAAS, so I wrote a simple EJB 3 bean to see how it works. @Stateless | @Remote({IGetUserName.class}) | public class GetUserName implements IGetUserName | { | SessionContext sc; | | @Resource | public void setSc(SessionContext sc) | { | this.sc = sc; | } | | @Override | public String getUserName() | { | if ( sc==null ) return "Context is null"; | | Principal p = sc.getCallerPrincipal(); | if ( p==null ) return "principal is null"; | | return p.getName(); | } | } | But when I call previous bean NullPointerException was throwed. The environment is : JBoss 5.0.0.GA, jboss was started with the configuration "default". No other changes to the jboss conf files. Does any one have an idea? I have looked around for a long time, but still don't know how to resolve it.

[JBoss Messaging] - Re: Stranges with message reading from queue

by gaohoward

Hi, the receiveNoWait means it doesn't wait until a message is received. You can't expect it will get something every time you called it. If you can get a message by receive(2000), try to replace it with sleeping 2000 ms and call receiveNoWait(). I bet you will get the messages.

No one at all? That's sort of disappointing. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4203833#4203833 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4203833

[JBoss Portal] - UserModule, Hibernate JTA transaction & Ajax Request

by guybedo

Hi, i have a portlet managing user identity related issues and accessing JBossPortal UserModule. Everything works fine when actions are inside a "classic" http request from the portlet, ex: <h:commandButton But when inside an ajax request fired by clicking on a a4j:commandButton or commandLink, it seems that no hibernate session to the portal database is created. Does anyone know how to setup the hibernate session creation on ajax requests ? thanks for your help View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4203828#4203828 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4203828

[JBoss jBPM] - Re: Ad-hoc one of workflow piece

by pjacobsen

Ronald.... thanks for the reply & I gotcha on the terminology. I had seen the milestone pattern before but I'm not sure if that meets my need? I don't really know when & where in the process definition the user will need to essentially pause the current execution.... perform some arbitrarily complex one-off process... and then return execution to their originally definition afterward. I think the disconnect for me is that my one-off process will not be defined in the original process or the flow. Examples For this process definition: start --> task 1 --> task 2 --> node 3 --> task 4 --> end We normally expect for the process instance to be just that. But on some occasions users need to be able to define any process that needs to be executed during only one particular instance of the process definition above. For example... while our token in on task 1.... they might say i need the following to execute after node 3 completes but before task 4 starts: task x --> node y --> task z making the execution: start --> task 1 --> task 2 --> node 3 --> (execute sub process above then return) -- > task 4 --> end or maybe for another instance they need the following to execute after task 1 completes but before task 2 starts: task m --> task n --> node o --> node p making the execution start --> task 1 --> (execute sub process above then return) -- > task 2 --> node 3 --> task 4 --> end Ultimately my problem is that not only is in not part of the flow... but really it's not a part of the definition either. It's a one-off process definition that needs to be executed at some point in a process instance (essentially pausing it... and then letting it continue after completion).

[Installation, Configuration & DEPLOYMENT] - Re: Setting Default Error Pages

by mduffy_lists

Here's the solution: Edit the web.xml in /opt/jboss-5.0.0.GA/server/default/deployers/jbossweb.deployer by adding  <error-page> <error-code>404</error-code> /error/error404.html </error-page> just after </welcome-file-list> Then the html and supporting files (images, css, etc.) go in /opt/jboss-5.0.0.GA/server/default/deploy/ROOT.war/error View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4203815#4203815 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4203815

[JBoss Messaging] - Re: What is the purpose of the Journal files?

by clebert.suconic＠jboss.com

On trunk, the journal-min-files is using 15. The journal is what stores the persistent-message. If you restart the server, we will recover a lot of stuff from our persistent store (the Journal).

[Beginners Corner] - Should entities bind to JNDI?

by culli

When I deployed an entity with EJB2/xdoclet I could specify a local-jndi-name in @ejb.bean and it would bind to a JNDI name. How do I do this with EJB 3 annotations? I'm using JBoss 4.2.3GA with no modifications and the first jboss example code from Enterprise JavaBeans 3.0 (Bill Burke/Richard Monson-Haefel). Very basic stuff. I can run the test client just fine. I'm checking the JNDIView bean for the Cabin bean and it's not there, but I can see the TravelAgent session bean. At some point I need to be able to look up my EJB 3 beans from legacy EJB 2 stuff that won't be converted (at least not within a year or so), so doesn't the EJB 3 entity need to be bound in JNDI?

[JBoss Messaging] - Stranges with message reading from queue

by romanenco

Hello I have question about receiveNoWait method. When I use it, it always returns null if I use this code: consumer.receive(2000) - everything is ok. I receive message. BUT if I use this code: consumer.receiveNoWait() - I do not receive any messages, My program must check queue periodically, using quartz - so I don;t want to block process pointing any time to receive() How can I make receiveNoWait() to return messages? thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4203799#4203799 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4203799
