[JBoss 6.1] How to disable unused stuff

mlo May 3, 2011 5:02 AM

Hello everybody !

We're currently using JBoss 6.1 Snapshot.

Our application uses :

- EJB 2 (Session & Message Driven)

- HornetQ (Queues & Topics)

- 2 data sources ( ---> MySQL DB)

We're running JBoss in default configuration. But, JBoss is very slow to start...

So we followed some tutos "Jboss slimming" in order to remove unused aspects of JBoss, but it still not enough.

My question :

- Can we start with the minimal configuration and add the needed jars/config files for our configuration?? We can't find out the config files/jars needed for ONLY ejb2/HornetQ/and data sources...

- Or, start with default configuration and remove all the not needed jars/config files??

Thanks in advance !

I turned on debug traces and :

17:19:21,346 DEBUG [BeansDeploymentAopMetaDataDeployer] Finished deploying AbstractVFSDeploymentContext@13547055{vfs:///E:/MLO/Work/applications/jboss-6.0.0.Final/server/default/deploy/transaction-jboss-beans.xml}
17:19:52,165 DEBUG [MappedReferenceMetaDataResolverDeployer] vfs:///E:/MLO/Work/applications/jboss-6.0.0.Final/server/default/deploy/DS_COTS.jar endpoint mappings:

We can see that there is 31 seconds between these 2 traces...

DS_COTS.jar is an archive which contains all the needed jar for our application...

It will be difficult to decide whether you statr with minimal and add Hornet+EJB2 or use default and remove all what you did not need.

I suggest to start with min, add ejb2 deployer (you might look what you can remove from deploy in case of sliming ), after that I think you have to add some libs because of ClassNotFoundExceptions.
After that add HornetQ deployables and fix similar.

helpful will be

I'm not sure whether an extreme sliming will have a big benefit of startup time and resource use ...

Hello, and first, thank you for your answer !

I already visited the 2 links you gave

I launched JBoss with remote debug, and, for 50 seconds~ Jboss is doing this :

Because we have a JAR archive which contains ~35 Jars (all the needed libs for our application)...

So I don't know what to do...

I found out a good thing

In the file JBOSS_HOME/server/default/deployers/scanning-deployers-jboss-beans.xml, we can specify ignored JARs for annotation processing.

I added to the list of ignored JARs my JAR, and it's Ok !!!

You have multiple jar files within some other jar file?

Hi mlo,

Could you please explain what you did to "specify ignored JARs" in scanning-deployers-jboss-beans.xml? I believe I'm having the same problem but can't find any documentation on doing this.

Regards,

Richard.

Hi !!

In scanning-deployers-jboss-beans.xml we just added something like :

<bean name="JBossCustomDeployDUFilter" class="org.jboss.deployers.vfs.spi.structure.helpers.VirtualFileDeploymentUnitFilter">
    <constructor>
      <parameter>
        <bean class="org.jboss.vfs.util.FileNameVirtualFileFilter">
          <constructor>
            <parameter>
              <map keyClass="java.lang.String" valueClass="java.util.Set">
                <entry>
                  <key>deployers/</key>
                  <value><null/></value>
                </entry>
                <entry>
                  <key>jbossweb.sar</key>
                  <value><null/></value>
                </entry>
                <entry>
                   <key>OurJar.jar</key>
                  <value><null/></value>
                 </entry>
