Hi all,
I am very frustrated by my conversation problem. I don't know where is wrong in my project settings. It seems that my environment only allows one conversation exist concurrently. For example, after I click @Begin to create a conversation SFSB, then when I try to click @Begin to start another conversation SFSB, I ALWAYS get an exception, which asks me to use @Begin(join=true), but they are two different conversation SFSBs. Following are my codes:
First, I use a conversation SFSB to find study list:<h:commandButton value="List Study" action="#{studyList.findStudy}"/>
|
|
| @Stateful
| @Scope(CONVERSATION)
| @Name("studyList")
| public class StudyListAction implements StudyList {
|
| ...
| @Create
| @Begin
| public init() {
| ...
| }
|
| @Begin(join=true)
| public String findStudy {
| ...
| }
|
| ...
| }
Then I try to create a new study at "Create Study":<h:commandLink value="Create Study" action="#{studyEditor.createInstance}"/>
|
|
| @Stateful
| @Scope(CONVERSATION)
| @Name("studyEditor")
| public class StudyEditorBean implements StudyEditor {
|
| ...
|
| @Begin
| public String createInstance {
| ...
| }
|
|
| ...
| }
At this moment, I always get the following exception:21:53:43,203 FATAL [application] javax.ejb.EJBTransactionRolledbackException: begin method invoked from a long running conversation, try using @Begin(join=true) on method: createInstance
