I am new to JBoss. I have a JBoss 4.2.0 running on RedHat CentOS 4.5
(2.6.9-42.0.3.EL_HPTRAID #1 SMP) that freezes every two to three days.
When it does so I see many httpd processes spawned. Httpd is still logging
request but 503 error is given. When I try to use kill -3 to get a thread dump
What is the difference between the two? Based on the source code javadoc:
TransactionSuccessEvent: An event that is processed when a transaction
completes succesfully
TransactionCompletionEvent: An event that is processed when a transaction ends
But I am not sure what the real difference is.
One solution that helps is to have a @Destroy method in which you cancel the
timer using timer.cancel().

I'd like to construct named anchors in the form of http://url#name in
s:link/. I tried to read the doc but didn't find anything. Is that possible?
How can I do it? Thanks.

I am wondering if there is anyway to not generate cid in url, for the purpose
of search engine optimization. Search engines will rank the page lower if there
are multiple urls pointing to the same page. Thanks.

I just upgraded my app to Seam 2.0 from Seam 1.2.1. The UI in firefox is now
pretty badly broken. I have mixed javascript with jstl to dynamically generate
javascript through a loop. Now the same code is fine in IE, but broken in
Firefox. What is weird is that when I saved the source to the
I have a permission requirement on objects that only owners or Admin role users
can update. I am ok with the Role part, using hasRole('admin'). But I am not
sure how to write ownership checking into a generic rule. Anyone has solved a
similar problem? Thanks.

The project is based on seam-gen. seam.properties is in the root level of the

I have a pojo bean annotated as @Startup and with entityManager injected. After
upgrading to 2.0 Beta1 and JBoss 4.2 the init method of the bean annotated with
@Create complained about null entityManager during startup. It used to work
fine under Seam 1.2.1GA and JBoss 4.0.5.
| @Startup

That is it! I changed core:managed-persistence-context/ to
presistence:managed-persistence-context/. I was following the instruction
here:
http://fisheye.jboss.com/browse/JBoss/jboss-seam/seam2migration.txt?r=1.2[/url].
I wish it could be more explicit though. Thanks.

Unfortunately it didn't work either. I removed the ejb annotations and made it
a POJO. Then I injected entityManager using @In, I got a similar problem, the
root of which is due to the micro-container (and the JNDI) not available before
the starting up of the bean:

Never mind. On closer inspection, your solution of adding
