[JBoss Messaging] - Re: Problem with large strings
by ONIT
Hello Tim,
Thanks for the quick response. Your results sound very encouageing. I didn't bother you with the details since I thought you would experience the same problem.
I am using:
JBoss_4_0_4_GA
JBoss Messaging 1.0.1.CR3
Windows XP Professional
Everything is on one JBoss server.
I have an EJB that is virtually identical to the messaging stateless EJB in the examples that come with JBoss Messaging. The EJB has a sendRequest method that puts a TextMessage in a queue named requestQueue and a getResponse method that retrieves TextMessages from a queue named responseQueue.
A MDB is listening on the requestQueue queue. It processes the request and puts the results into a TextMessage and sends it to the responseQueue queue. The EJB then retrieves the TextMessage from the responseQueue.
My queues are configured in the destinations-service.xml as follows:
<mbean code="org.jboss.jms.server.destination.Queue"
name="jboss.messaging.destination:service=Queue,name=requestQueue"
xmbean-dd="xmdesc/Queue-xmbean.xml">
<depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer
750000
20000
20000
<mbean code="org.jboss.jms.server.destination.Queue"
name="jboss.messaging.destination:service=Queue,name=responseQueue"
xmbean-dd="xmdesc/Queue-xmbean.xml">
<depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer
750000
20000
20000
The server log is:
09:24:35,828 INFO [Queue] Queue[/queue/requestQueue] started, fullSize=750000, pageSize=20000, downCacheSize=20000
09:24:35,828 INFO [Queue] Queue[/queue/responseQueue] started, fullSize=750000, pageSize=20000, downCacheSize=20000
I am running the application in debug mode in Eclipse. I am using a memory monitor in Eclipse to track memory usage.
The program uses about 80M of memory. When I process the first large string (about 380k), memory climbs to about 150M and I start getting these messages in the server log:
09:42:56,343 WARN [SimpleMemoryManager] Less than 25% of total available memory free
The next time I process the same request memory grows to about 360M and I get more of the above messages. The more requests I send (one at a time) the more the memory grows.
Response times are about 30 to 35 seconds.
Any clue?
Thanks,
Dennis

[JBossWS] - 1.0.2: Exception when client receives a JavaBean
by Juergen.Zimmermann
Using the new version 1.0.2 on the client side I get the following exception when the JBoss server transmits a JavaBean. Any hint is appreciated!
