[Clustering/JBoss] - unusual clustering error causing jboss apps to freeze.
by lazybeans
I have two jboss 4.0.4CR1 w/ejb3 servers clustered with session failover. They were running great for about 1 month. Then all of a sudden out of nowhere I get this clustering warning message on both machines and both of them freeze all of sudden. I had to kill both app servers and restart as a consequence.
Below is a sample of the messages from one of the machines, the other machine exhibits similar messages (twiddle and toodle are the two names of the machines).

[Installation, Configuration & Deployment] - Trouble with LinkageError
by msolnit
I must admit, I've read a lot of the documentation (including the three class loader articles on the wiki), and some other forum posts, and I still don't get it.
The goal is the following:
1) Use our own copy of any utility JAR's we choose to deploy (STaX, for example, or Apache Axis).
2) Use the JBoss copy of any utility JAR's that we don't deploy (Xerces, for example).
3) Have both a "production" and a "development" version of our product running in the same JBoss instance.
We deploy our app as an EAR file containing utility JAR's and a single WAR. To make everything work correctly, I've added the following jboss-app.xml file:
| <jboss-app>
| <loader-repository>
| www.foo.com:loader=foo-demo.ear
| <loader-repository-config>
| java2ParentDelegation=true
| </loader-repository-config>
| </loader-repository>
| </jboss-app>
|
The development version and the production version have different JMX names for the loaders.
With this configuration, everthing was working fine, until I tried to use an Apache Axis client for a web service.
All of a sudden, we are getting "java.lang.LinkageError: loader constraints violated when linking javax/xml/soap/MimeHeaders class" whenever we try to use this client.
The weird things:
1) Whichever version of the app is accessed first will work. So for example, if I hit production first then production works and dev fails, vice versa.
2) The JMX console shows that javax.xml.soap.MimeHeaders is being loaded into a single UCL for each hierarchical loader, which is what we want, right?
I would appreciate any help.
Sincerely,
Matt

[JBoss Seam] - create method not found + @Factory
by Basel
Hello,
I am trying to cerate a new entry, entity bean, using three pages with the help of jBPM similar to the example illustrated in jbossworld-seam-lab.zip file. These three pages are going to be used in a RESTful application that follows the blog example.
So, I have a data entry page called newentry.jsf, similar to the bolg example, that has a reference to a variable created with the help of the @Factory annotation. In that page the variable is referenced just like any bean:
| <h:inputText id="title" value="#{newEntry.title}"
| size="70" maxlength="70" required="true"/>
|
The method that creates the variable is in a stateful session bean, to take advantage of jBPM pageflow:
| @Stateful
| @Name("postAction")
| public class PostAction implements PostActionInterface{
|
| @In(create=true)
| private Category category;
|
| //@In(create=false, value="newEntry")
| @In(create=false)
| private Entry entry;
|
| @Factory("newEntry")
| public void createNewEntry(){
| entry = new Entry(category);
| }
|
| @Logger
| private Log log;
|
| //@Begin(pageflow="new-entry", join=true)
| @Begin(pageflow="new-entry")
| public void startPost(){
| log.info("Starting to create a new post");
| }
|
| @Remove @Destroy
| public void destroy(){}
| }
|
As you might have noticed, there is a page event in pages.xml that is supposed to call startPost() method in order to start a new conversation:
| <page view-id="/newentry.jsf" action="#{postAction.startPost}"/>
|
Unfortunately, when I try to access the newentry.jsf page I get the following stacktrace:
