    Persistance service problems.

    infectedrhythms Nov 22, 2004 2:46 PM

      I read the wiki it seems I have implemented evrything ok...

      1- When I wrap my Mbean as an XMBean it seems that I loose my Mbeans operations... The JMX console does not see the operations...
      2- It doesnt seem to persist.

      Am using JBoss 4.0.0

      here is my XML configurations and code...

      My Mbeans jboss-service.xml...

      <?xml version="1.0" encoding="UTF-8"?>

<server>
 <mbean code="org.package.TestService" name="package.org:service=TestService" xmbean-dd="">
 <xmbean>
 <description>PersistentServiceExample</description>
 <descriptors>
 <persistence persistPolicy="OnUpdate" persistName="PersistentServiceExample"/>
 <persistence-manager value="org.jboss.mx.persistence.DelegatingPersistenceManager"/>

 </descriptors>
 <class>org.jboss.jmx.examples.persistence.PersistentServiceExample</class>

 <attribute access="read-write" getMethod="getParam" setMethod="setParam">
 <name>Param</name>
 <type>java.lang.String</type>
 <value>Hello World</value>
 </attribute>
 </xmbean>
 </mbean>
</server>


      jboss-service.xml persistance config... 
       <!-- ==================================================================== -->
 <!-- XMBean Persistence -->
 <!-- ==================================================================== -->
 <mbean code="org.jboss.system.pm.AttributePersistenceService"

 </attribute>
 <attribute name="ApmDestroyOnServiceStop">false</attribute>
 <attribute name="VersionTag"></attribute>
 -->
 </mbean>


      Mbean java file... 
      package org.package;

import org.jboss.system.ServiceMBeanSupport;

public class TestService extends ServiceMBeanSupport implements
 TestServiceMBean
{
 String param = "Not initialized.";

 public void setParam(String param)
 {
 this.param = param;
 }

 public String getParam()
 {
 return(param);
 }

 public void printParam()
 {
 log.info("Param value: " + param);
 }

 protected void startService() throws Exception
 {
 log.info("Starting service...");
 }

 protected void stopService() throws Exception
 {
 log.info("Stopping service...");
 }
}

          You need also to specify your operations in the xmbean descriptor, i.e. the printParam() and (since you extend ServiceMBeanSupport) the lifecycle method create()/start()/stop()/destroy() and the 3 attributes Name/State/StateString.

          You can use the following convenience xml entities: (for an example see
          the following descriptor conf/xmdesc/ClientUserTransaction-xmbean.xml)

           &defaultAttributes;
 ...
 &defaultOperations;


          If this doesn't work, then just replace with: 

          <operation>
 <description>Standard MBean lifecycle method</description>
 <name>create</name>
</operation>
<operation>
 <description>The start lifecycle operation</description>
 <name>start</name>
</operation>
<operation>
 <description>The stop lifecycle operation</description>
 <name>stop</name>
</operation>
<operation>
 <description>The destroy lifecycle operation</description>
 <name>destroy</name>
</operation>
<operation>
 <description>The detyped lifecycle operation (for internal use only)</description>
 <name>jbossInternalLifecycle</name>
 <parameter>
 <description>The lifecycle operation</description>
 <name>method</name>
 <type>java.lang.String</type>
 </parameter>
 <return-type>void</return-type>
</operation>

and

<attribute access="read-only" getMethod="getName">
 <description>The class name of the MBean</description>
 <name>Name</name>
 <type>java.lang.String</type>
</attribute>
<attribute access="read-only" getMethod="getState">
 <description>The status of the MBean</description>
 <name>State</name>
 <type>int</type>
</attribute>
<attribute access="read-only" getMethod="getStateString">
 <description>The status of the MBean in text form</description>
 <name>StateString</name>
 <type>java.lang.String</type>
</attribute>

            Thanks I also managed to put the xml with my jboss-service.xml instead of the external descriptor...

            But it still doesnt seem to persist! :(

            <?xml version="1.0" encoding="UTF-8"?>

 &defaultOperations;

            and 

             <mbean code="org.jboss.system.pm.AttributePersistenceService"

              Have you tried the demo service from docs/examples/jmx/persistent-service.sar?

              I see you use a persistName "TestService.ser", if you don't specify anything you should get an .xml file inside /data/xmbean-attrs/ as soon as you change the value of "Param" using the jmx-console.

              What are the steps you follow?

                Actually yes I have infact I copied the example ;)

                Even the example did not work.

                I run Jboss 4.0.0 as default.

                And then I cut and paste TestService.sar in the deploy folder...

                Here I will provide my code and XML descriptors...

                jboss-service.xml for my Mbean...

                Ass for persisteName I get an exception listed below the code...

                <?xml version="1.0" encoding="UTF-8"?>

 }
 catch(Exception ex)
 {
 log.error(ex.toString());
 }
 }

 protected void stopService() throws Exception

}



                The reason I use persiste name is because if I don' t use it Iget the following exception when deploying...

                  Try to remove the DOCTYPE and tell me how it goes.

                  It refers to the xmbean descriptor but you've included in the mbean descriptor.

                    If I remote the descriptor I get an error that the &DefaultAttributes and &DefaultOperations; elements are not defined...

                    May I call you am currently at work, maybe we can resolve this abit quicker ;)

                        Maybe it's broken on 4.0. I'll do some tests and let you know.

                            I just tries it under 3.2.6 as well it still complains that persistName is required.

                              Hmm.. It has something to do with jdk5. With 1.4 it seems ok.

                                  Everything works fine on 1.4 (all versions I tried).

                                  Something weird is happening with jdk5, and it affects the old ObjectStreamPersistenceManager, too.

                                    yeah I tried the sample here at home and it worked fine!

                                    It looks like 1,5 is breaking quite afew thing all around...
