1. Re: New problem deploying MDB in latest code
adrian.brock Dec 17, 2004 6:43 AM (in response to jplsaez22)Great. I guess the jboss-all vs jboss thing was confusing me. I can build both the 2.5 HEAD revision and the latest 2.4 branch now.
Getting back to the original question, both these builds are giving me the same problem. I do not have the problem with 2.4.0.
I create a queue in jboss.jcml like this:
I then deploy a trivial MDB on it (using auto-deploy directory before starting the server). My jboss.xml looks like this:
<enterprise-beans>
<message-driven>
<ejb-name>TestModule</ejb-name>
<configuration-name>Standard Message Driven Bean</configuration-name>
<destination-jndi-name>queue/testModuleQueue</destination-jndi-name>
...
Deployment fails with the error messages in the original post. It seems the server:
- looks for the testModuleQueue
- misses it somehow
- tries to create a temp queue with the same name for the bean deployment
- fails because there really is a queue deployed with that name already
If i do not create the queue in jboss.jcml, the server creates a temp queue and deploys the bean on it successfully. But i don't want my bean on a temp queue!
New info since the original post: If i autodeploy the same bean again (without restarting jboss), i get a new exception:
[J2eeDeployer] exception while searching deployment:
java.io.FileNotFoundException: S:\jboss-2.4\jboss\dist\tmp\deploy\Default\my.ear\deployment.cfg (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.(Unknown Source)
at java.io.FileInputStream.(Unknown Source)
at org.jboss.deployment.InstallerFactory.loadConfig(InstallerFactory.java:264)
at org.jboss.deployment.InstallerFactory.findDeployment(InstallerFactory.java:198)
But i also see:
[Container factory] Deployed application: file:/S:/jboss-2.4/jboss/dist/tmp/deploy/Default/my.ear/
[J2EE Deployer Default] J2EE application: file:/S:/jboss-2.4/jboss/dist/deploy/my.ear is deployed.
No destroy message. So the bean does deploy the second time. It also appears to be receiving messages.
Any further redeployments give the same result. -
2. Re: Intercepting queue length
adrian.brock Dec 17, 2004 12:09 PM (in response to jplsaez22)The only mechanism to do this involves JBoss specifc mechanisms.
Either through the JMX management interface or by modifiying the JBossMQ code.
Monitoring the queue depth is not a part of the JMS spec. -
3. Re: Intercepting queue length
jplsaez22 Dec 17, 2004 1:21 PM (in response to jplsaez22)Ok.
Should it be possible to set a destination, call it "queue depth under threshold" where the monitored destination could send a JMS message telling the queue depth limit has been reached?
Could you please tell me some hints about where I should change the code?
Thank you very much.
