[Clustering/JBoss] - Use TomcatClusteringCache or create my own cache service?

by cristant＠fstrf.org

I need to share a small amount of data between members of my JBoss cluster, and I think a JBossCache instance will do the trick. Is it better to use the already existing TomcatClusteringCache used by the ClusteredSingleSignOn valve or to create my own JBossCache MBean service instead? We are basically just using a remote procedure call (XMLRPC at the moment) to write a small packet of data about a user being redirected into JBoss from a legacy system so they can be logged in automatically when the legacy system forwards them to JBoss. I'd just be using the JBossCache as a distributed hash map so that the user can pick up their information packet regardless of which member of the cluster they are directed to. Thanks in advance, ~Matt View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4088605#4088605 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4088605

[JBoss Seam] - Re: Seam 2 CR1 upgrade issues

by seamdev

I solved the XML Parsing Error. It was due to one of the xhtml file being included from template.xhtml. Header for included files seems to have changed, see header of conversations.xhtml in the jpa example in seam2 and seam1.2.1. Perhaps it should be documented in seam 2 migration guide.

[EJB/JBoss] - Noob query problem :/ simple select clause.

by Yacho

Im using Seam in general but this one is about EJB-QL only i think... i have a following query : anonymous wrote : User existing = (User) em.createQuery("SELECT OBJECT(u) FROM User u WHERE u.login=#{newUser.login} AND u.passwdHash=#{newUser.passwdHash}").getSingleResult(); and i constantly get such Exception : Exception during request processing: | Caused by javax.servlet.ServletException with message: "#{userManager.register}: javax.ejb.EJBTransactionRolledbackException: No entity found for query" As far as i know if query returns no results it should return null ... so how to deal with it ?

[Performance Tuning] - JBoss AS Freezes with 99.9% CPU After 1 Hour in Production

by gudmundsonsc

I am having a difficult time figuring out the cause of this. I recently installed jboss 4.2.1.GA jdk 1.5.0_11 on linux. We have 3 servers running 4.0.5.GA and now 3 new servers with 4.2.1.GA. Only on the 4.2.1.GA servers after an hour of web traffic, the java CPU utilization in top shows 99.9% and JBoss tomcat :8080 and :8009 ports are not responsive. Once in this state I cannot run the listThreadCpuUtilization MBean operation to see what thread is taking up the most cpu. I have attached jmap and jstack outputs to this post. Can you help me figure out what thread might be the source of the problem? Is it normal to see so many threads state = BLOCKED? Any ideas?

only calls it once if getSeedSelection() returns false. we're going to check for null on instance variables that are loaded (choices) to avoid DB round trips View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4088595#4088595 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4088595
