[JBoss Seam] - Re: Seam 1.2.0 with Jboss 4.2.0

by carlsz

I'm having the same issue using JBoss 4.2.0.GA, Seam 1.2.1.GA with JSF 1.2 and Drools. When I include the el JARs in my EAR, the server hangs on startup. Did you happen to find a solution to your problem? Thanks.

[JBoss Messaging] - Re: Selector Help needed - Possible alternative suggestions

by timfox

In general it's a bad idea to use selectors with queues since it requires the entire queue to be scanned every time delivery is attempted (slow). In most cases this can be refactored into using a topic with durable subscriptions - one durable subscription for each of your consumer types. The selector on the durable sub is evaluated *before* the messages reach the durable sub, so it is much more efficient. (Think of each durable subscription of a queue, but it only contains those messages which match the selector). Durable subscriptions can be clustered in JBM so you can have more than one consumer on the same durable subscription on different nodes of the cluster. (There is an issue with message redistribution in 1.3.0 which reduces performance for this, but this will be fixed in 1.4.0.) The issue about a message consumer getting "all" the messages is because each message consumer buffers ("prefetches") into its local buffer. This is done for performance reasons. For high throughput it is much more efficient not having to go the server every time you want a message. If this is a problem for you, you can reduce the prefetch size - this is explained in the userguide.

[JBoss Seam] - Re: Problem with entity in session scope and JSF inputText

by amitdk

Thanks.That worked - where can I find this information? I've been looking through the docs and unable to find such specifics. Another problem(though it may not be the right place for the post) I am noticing is that the ajax call to rerender the inputText field does not evalualte the EL expression - selectedTimeline.startDate unless inputText is set for disabled= true. Anyone come across this? - Amit View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4057185#4057185 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4057185

[EJB 3.0] - Re: Bidirectional Cascade

by waynebaylor

The cascade setting will only work in one direction, so if you put it on the OneToMany relationship you can remove entities from the collection without fear of deleting the parent. As for the second question, if you have CascadeType.ALL set, then you won't be able to set the ManyToOne side because it will be deleted when the other side is deleted. Hope that helps :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4057183#4057183 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4057183

[EJB 3.0] - Re: detached entity passed to persist

by icordoba

I see this is an old thread but just in case someone nees a solution... try to enclose everyting in a UserTransaction. If you take an EJB3 entity outside the transaction, you cannot re-persist it or iterate over CMRs, etc. You need then a UserTransaction in the client side.

[JBoss Seam] - Re: Problem with entity in session scope and JSF inputText

by pete.muir＠jboss.org

For a start you aren't accessing TimelineChangeListener in a way in which Seam can intercept calls (so the @Out won't happen). Use a EL binding #{foo.timelineChangeListener} instead.
