[JBoss Seam] - Seamgen 1.1CR: Exception in thread

by Faerine

I am trying to use the versio of Seamgen in Seam 1.1CR (./seam setup), and there is a problem Seam's embedded Ant. Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/Launcher It gives the same error on a computer that has a separete system-wide Ant installation and on a computer that doesn't (both of them Ubuntu Linux), so it shouldn't be an Ant conflict as Ant's forums suggest. The relative paths to the embedded Ant installation are correct. I also tried absolute paths, even setting the system-wide ANT_HOME to point to Seam's lib dir - nothing happens. I have had no problems using the old Seamgen (which required Ant to be preinstalled).

[Remoting] - Client timeouts while waiting for response from server

by tomerc

Hi, I am running JBoss 4.0.4GA over Redhat AS 4 with jboss remoting version 1.4.3GA and i am expriencing the following problem: Under heavy load on the client machines the following exception is shown: Socket timed out. Waited 1800000 milliseconds for response while calling on InvokerLocator this error appears on all of the client machines for afew minutes and afterwards the following error is shown: Can not get connection to server. Problem establishing socket connection. Upgrading to version 1.4.5GA as the following link suggests , did not solve the problem http://www.jboss.com/index.html?module=bb&op=viewtopic&t=80814 When the problem occurs all of the connections to port 8084 on the server machine are either in SYN_RECV or in CLOSE_WAITING state, only a restart to the jboss process solves the problem for afew hours. Any help would be highly appreciated Thanks alot.

[Performance Tuning] - Identifying performance bottlenecks

by jshrinivas

Hello, I have a benchmarking application running on JBoss. The application gets requests from a client driver which keeps on sending requests at around 2000 requests per second. Although JBoss processes the requests without any errors the CPU utilization on the JBoss machine doesnt goes beyond 70%. It is not waiting for I/O, N/W seems perfectly fine and DB machine is also performing optimally. The JVM arguments for JBoss process are tuned for GC, Heap size etc. The h/w on which JBoss is running is powerful enough to handle such load easily. I wanted to know what things one should look in to in such a situation? Are there any tools that can point where the bottleneck lies? What JBoss configuration changes one should look in to? BTW I am using a slimmed version of JBoss and have done config changes according to the wiki page for performance optimization.

[JBossCache] - Re: Error starting cache with TCP and TCPPING

by bela＠jboss.com

It's JGroups: set TCP.enable_diagnostics="false", and this will go away. It is a multicast address used for probing JGroups instances in a network. This is described in detail on the JGroups wiki View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989765#3989765 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3989765

Why would it try to bind to a mcast address?

[Installation, Configuration & Deployment] - Re: jboss startup web-console.war deployment errors

by vladimir.ralev＠jboss.com

The problem comes from a misconfigured deploy\console-mgr.sar\web-console.war\WEB-INF\jboss-web.xml The installer creates: <jboss-web> |  | <security-domain>java:/jaas/jmx-console</security-domain> | </jboss-web> where it should have been: <jboss-web> |  | <security-domain>java:/jaas/jmx-console</security-domain> | <depends>jboss.admin:service=PluginManager</depends> | </jboss-web> Just add the line to your file. We will fix it in the next release.

[JBossCache] - Re: Transactions problem

"manik.surtani(a)jboss.com" wrote : You can't. We don't do cluster-wide locks. :-) Remote locks are obtained on transaction commit time. OK., Lets assume a situation where N services on N different JBoss instances are reading and modifying data, how data integrity can be achieved? Only by catching failed transactions and re-running them again?

[Persistence, JBoss/CMP, Hibernate, Database] - Re: Existing column but column not found - urgent

by Melladh

I forgot to add that I'm using JBoss 4.0.3 AS, and MySQL as a database. I have not done anything else to configure it to use MySQL than to add the ds.xml as defined in the tutorial, and ofcourse the internal application mappings. So I don't know if I need to make settings elsewhere to define how it should treat it. But as mentioned, I don't get any errors when I only use my PersonBean which inserts to the person table.
