JBoss-3.0.0RC1 does not redeploy MBean

[qwang]

I am using JBoss-3.0.0RC1 on Windows2000. When I redeploy, using hot-deploy, a SAR file for a MBean, the existing MBean is not undeployed and the existing SAR file is not replaced. There is no any message come to the app server's console.

Any idea how to make the hot redeploy work?

More info please.

You asked this before in another post, but all you posted
was that the manifests could not be found and that it
didn't work.

Can you explain the packaging.
Does it deploy and run correctly the first time?
Have you tried with latest CVS, RC2 should be out soon?

The most common reason for deployment stopping is because
a deployment hangs. e.g. a database url is misspelt
and the connection hangs forever. Maybe you have the
same problem?

Can you hot deploy other things besides your SAR.
Try touching jetty-plugin.sar or tomcat4-service.xml
to see whether they redeploy.

Hi Adrian,

In hot deployment, the MBean always get deployed first time although there appear those error or warning messages, and its operations can be invoked without problem. But subsequent redeployment has no response from the server. EAR files can be redeployed many times.

In static deployment (i.e. copy SAR to deploy directory and then start the server), there is no exception message saying "Class not found ..." but only warning messages saying like:

"11:38:22,203 WARN [MainDeployer] The manifest entry in file:/H:/evodev/jboss-3.
0.0RC1_tomcat-4.0.3/server/default/deploy/framework-deployment.sar references UR
L file:/H:/evodev/jboss-3.0.0RC1_tomcat-4.0.3/server/default/deploy/library/fram
ework-repository.jar which could not be opened, entry ignored"

But the MBean is still deployed and its operations can be invoked without problem.

I am going to try to use the latest code of RC2 from CVS.

Thank you.

Hi Adrian,

The packaging of my SAR file:

class files of the MBean and help classes
xxxxxxxMBean.class
...................
...................
library\libjar1.jar
library\libjar2.jar
...................
META-INF\jboss-service.xml
META-INF\MANIFEST.MF

Here are the contents of MANIFEST.MF:

Manifest-Version: 1.0
Created-By: Ant 1.4.1
Class-Path: library/log4j.jar

Thank you for help.

I'm still not sure about your problem.

You start the server and

framework-deployment.sar is deployed with warnings and
another.ear is deployed

You can then redeploy
another.ear as many times as you like

If you redeploy framework-deployment.sar you get
no output from the server but
when you try to use it you get a ClassNotFoundException?

Can you check log/server.log, to see whether there
are debug messages in there?

Regards,
Adrian

Hi Adrian,

Sorry for not being able to make the problem clear. Now I don't get the ClassNotFoundException any more.

The following is the sequence of my deployment operations:

1. Start JBoss server.

2. After started JBoss server, start to build and to hot-deploy my MBean, ComponentDeployer, with build.xml.

3. The server output the following messages:

4. Successfully eploy and undeploy a EJB EAR file, test.ear, many times by invoking the methods of the MBean, ComponentDeployer.

5. Repeat step2 to redo the hot deployment of the MBean, no output from the server at all to either console or server.log.

6. Repeat step 4 successfully.


The problem is that the server never output any message to for undeoly and redeploy the MBean.


This message might be clearer.

Got it, I think.

You say you are hot-deploying the sar.
The directory mentioned above isn't the normal
hot-deploy location
i.e. server/default/deploy

Have you added your sar's location or its directory to
the URL scanner in jboss-service.xml?

Hot deploy only works for urls known to the URL scanner.

Hi Adrian,

JBoss-3.0.0RC1 server redo the hot-deploy of the MBean after I added the path of directory of the MBeans SAR file to the URL Scanner. It is a big progress for me. However, the server tries to deploy the same MBean twice each time when the MBean is deployed and the server then throw an exception with error message saying "xxxxxx already registered ....". Although it does not affect the use of the MBean, it puts alot of exception messages on the screen each time the MBean is redeployed.

Any further suggestions?

Thank you.

When YOU redo the hot-deploy?

The hot-deploy should be automatic when you change
to sar.

Adrian

Adrian,

I have got it work now. But, I still have a question. Copy SAR file to ./deploy or any URL registered to URLDeploymentScanner set-up is not really what I mean by "hot deploy". By "hot deploy", I mean to deploy a SAR file from a directory that is not registered for deployment scanning, e.g. the one I used before, after the file is built and by calling org.jboss.jmx.client.Deployer in build.xml file.

It seems JBoss hasn't got this work for redeploy SAR. First time deploying SAR file works, but not the subsequent deployment.

Hope I have made my problem clear.

Thanks.

Ok,

No wonder I couldn't understand your problem :-)

You are correct deploy on something that is already
deployed does nothing.
You have to "-undeploy" it first.

Adrian

[qwang]

JBoss-3.0.0RC2 has sorted the problem out. It now can redo the "hot deploy" as I meant. :-)

qwang

[qwang]

But the RC2 build from the code checked out from CVS hangs at IIOP starting up. :-(

[adrian.brock]

Is it the address problem?

Do "netstat -a" and check the port is not being used
already. You can change the port in iiop config file
in deploy.
