[JBoss Seam] - a problem with jBpm in Seam

by mnrz

Hi I am trying to change registration example in order to work with JBpm. but at the first page it is a button with action #"{register.register}" I define in pageflow if the user already exists tnot change the current page and if not, go to next page, but It calls action register first and it check the database and because user is not exist then that action persist the data into the database and that action is calling again and in the second time, that user already persisted so the current page staty intact and a message will be displayed. here is pageflow definition file: | <pageflow-definition name="SeamPracticePageFlow"> | | <start-page name="start" view-id="/pages/register.jsp"> | <transition name="register" to="checkUser" /> | </start-page> | | <decision name="checkUser" expression="#{register.alreadyExists}" > | <transition name="false" to="registered" > | <action expression="#{register.register}" /> | </transition> | <transition name="true" to="start" /> | </decision> | | <page name="registered" view-id="/pages/registered.jsp"> | <redirect/> | <transition name="welcomeMessage" to="listMessage" > | <action expression="/pages/messages.seam" /> | </transition> | </page> | | <page name="listMessage" view-id="/pages/messages.jsp"> | <redirect/> | <end-conversation/> | </page> | | </pageflow-definition> | and jsp file: | <f:view> | <h:form> | <table border="0"> | <s:validateAll> | <tr> | <td>Username</td> | <td><h:inputText value="#{user.username}" required="true"/></td> | </tr> | <tr> | <td>Full Name</td> | <td><h:inputText value="#{user.fullName}" required="true"/></td> | </tr> | <tr> | <td>Password</td> | <td><h:inputSecret value="#{user.password}" required="true"/></td> | </tr> | </s:validateAll> | </table> | <h:messages/> | <h:commandButton type="submit" value="Register" action="#{register.register}"/> | </h:form> | </f:view> | and the action: | @Create | @Begin(join=true,pageflow="SeamPracticePageFlow") | public void register() { | try { | if(isAlreadyExists()) { | userNotExists = false; | em.persist(user); | logger.info("user #{user.username} registered."); | //return "/pages/registered.jsp"; | }else { | logger.info("user #{user.username} already registered."); | userNotExists = true; | } | } catch (Exception e) { | e.printStackTrace(); | } | | } | | public boolean isUserNotExists() { | return userNotExists; | } | | public boolean isAlreadyExists() { | try { | List registered = em.createQuery("select username from User where username = :u") | .setParameter("u",user.getUsername()) | .getResultList(); | if(registered == null || registered.size() == 0) { | return true; | }else { | FacesMessages.instance().add("user #{user.username} already exists."); | return false; | } | }catch(Exception e) { | e.printStackTrace(); | } | FacesMessages.instance().add("something's wrong..."); | return false; | } | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3981675#3981675 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3981675

by kimatrix

Yes i have a legal MQ. But i don't see how this could be MQ issue, it's jboss who is holding the message. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3981674#3981674 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3981674

[Clustering/JBoss] - Re: Is it possible to factor out jboss rmi and use in a j2se

by ben.wang＠jboss.com

It may not be easy after this is the clustered middleware all about. :-) In JBoss clustering, in addition to HA proxy for client side, you will also need to know the current membership (DistributedReplicantManager) so you know where to failover, and then you will have a separate replication layer. After you go through all these, it'd be a whole lot easier just to do the clustering via ejb3, e.g. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3981671#3981671 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3981671

[Clustering/JBoss] - Re: RoundRobin, new cluster member & SFSB == NPE

by ben.wang＠jboss.com

It seems that the clustered cache instance in the new node is not ready and therefore the NPE. Can you send me your code for me to try? It'd best to have source as well. Thanks.

by SchlauFuchs

Tried that, the result is mappedBy reference an unknown target entity property: <packagename>.ArticleConsumeSchema.schema in <packagename>.ConsumeSchema.articleSchemas schema is an inherited attribute - and that worked earlier. Next suggestion, please?

[Clustering/JBoss] - Re: how can i configure webapps deployoed across a cluster

by ben.wang＠jboss.com

You can try to share the same conf and deploy directory across servers via a share drive, e.g. Check out the jboss admin guide online for details on how to define it via property setting.
