[Clustering/JBoss] - ERROR [ProtocolStack] no down protocol available !

by ngcpaiva

I have JBoss in a 2-node cluster. After a few days of uptime, I see the following message show up on the logs. Once this message starts to appear, the requests start favoring the node that does not see the messages, but some requests still make it over to the server instance that is having the issue. Console.log: ERROR [ProtocolStack] no down protocol available ! Server.log: ERROR [org.jgroups.stack.ProtocolStack] no down protocol available ! The JBoss cluster seems to be working fine for a while as I don't see any issue in the cluster communication. Eventually however, both nodes require a restart, as it leads to cluster members failing to communicate. The message keeps being logged in the files every other second, filling up the files. There is no full stack trace. Just the message as shown. We have an application that uses the Flex framework and communicates with JBoss to get data from a MySQL database. The JBoss cache is communicating over UDP. We are looking into making a change soon to communicate over TCP instead. Other information: JBoss: 4.0.5GA built on October 16, 2006 JDK: 1.5.0_09-b03 (Sun) OS: Linux Red Hat (2.6.9-55.0.2.ELsmp) Hardware: Intel Quad-core 2 physically identical machines each with one node, and running 1.5GB of heap. Thank you in advance for any pointers.

[Persistence, JBoss/CMP, Hibernate, Database] - Re: Injected EntityManager in SLSB after an exception

by lpmon

I have a simple test case I created to experiment with behaving as expected. When I determine why the offending code is behaving this way I will post it with an explanation.

[JBoss Seam] - Seam skeleton misbehaving?

by Sammy8306

I created an empty new project using seam-gen. Then, I login using as 'user1'. I manually navigate to the login.xhtml view, and login again using the same username. This works. Then, I logout. Surprise, I'm still logged in! Logout again, and then you're not logged in anymore. So, in effect I can login with multiple identities? Is this intended behavior? There is a login.page.xml file which redirects to home.xhtml if identity.loggedIn is true, however this doesn't seem to work.

[JBoss Messaging] - Re: Clustered environment with non persistent messages ?

by mvecera＠redhat.com

Hello, I'm afraid it is not very safe to have non-persistent messages here. The clustered queue shares the messages in database. If the messages aren't persistent and one node in the cluster has a message ready for processing, the message can be lost in the case of failure. But I would suggest you first switch to JBoss Messaging 1.4.0.SP3 and ideally a newer JBoss AS (4.2)...

[EJB 3.0] - Re: ArrayStoreException when accessing bean from war

by jaikiran

As per the javadocs of ArrayStoreException: anonymous wrote : Thrown to indicate that an attempt has been made to store the wrong type of object into an array of objects. For example, the following code generates an ArrayStoreException: | | Object x[] = new String[3]; | x[0] = new Integer(0); | You say that it works with JUnit and not from a war deployed in the server. Is this war a different application? How are you applications packaged?

by hubaghdadi

Hi. Any special steps should be taken into account when trying to deploy a POJO war Seam application (JavaBeans, Entity beans) to Glassfish? (except for creating a datasource via Glassfish console) Thanks.
