[JBoss-user] [Clustering/JBoss] - Re: how to bind a serializable object into HA-JNDI
Sorry, thats a misunderstanding. I was not precise enough. Using port 1100, thats what I did, and the name IS definitely in HA-JNDI. When I do a lookup on all the nodes of the cluster, the name is bound and there. But when I want to access the returned object, its null. For binding, I used the NonSerializableFactory class, and obviously thats the reason why this does not work (according to what I read in the forum). But what can I use instead? How can I bind an object to HA-JNDI so that it stays serializable?

[JBoss-user] [Clustering/JBoss] - how to bind a serializable object into HA-JNDI
Hi, Can anybody help me? This JNDI is driving me mad... How can I bind a serializable(!) object to HA-JNDI, so that this object can be accessed and used clusterwide? Or is it just a dream I have? I know that there is a NonSerializableFactory to bind things into (HA-)JNDI, but this solution only works on the local machine. I just want to store a String object in HA-JNDI which tells everyone in the cluster which node is the master node so that the started singleton MBeans can be directly accessed. How can I achieve that? Or has anybody got another idea of how to globalize this master information? Thanks a lot, Marion View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3840095#3840095 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3840095 --- This SF.Net email sponsored by Black Hat Briefings Training.

[JBoss-user] [Clustering/JBoss] - several singleton MBeans: can master node for each one be di
Hi, In our cluster, we want to use several different singleton MBeans, lets say MBean A and MBean B should only be active on one node (master node) in the cluster. I have declared the following in my hasingleton-example-service.xml file: | mbean code=org.jboss.ha.singleton.HASingletonController | name=jboss:service=HASingletonMBeanExample-HASingletonController | dependsjboss:service=DefaultPartition/depends | dependsmyservice:service=MBeanA/depends | attribute name=TargetNamemyservice:service=MBeanA/attribute | attribute name=TargetStartMethodstartSingleton/attribute | attribute name=TargetStopMethodstopSingleton/attribute |/mbean | |mbean code=org.jboss.ha.singleton.HASingletonController | name=jboss:service=HASingletonMBeanExample2-HASingletonController | dependsjboss:service=DefaultPartition/depends | dependsmyservice:service=MBeanB/depends | attribute name=TargetNamemyservice:service=MBeanB/attribute | attribute name=TargetStartMethodstartSingleton/attribute | attribute name=TargetStopMethodstopSingleton/attribute |/mbean | Both services are set to active state on the master node, and when the master node comes down, another master node is elected, thats okay. But what if there are multiple nodes in the cluster? Can I be sure that active MBeanA and MBeanB reside always on the same node?? Or does the notion of master node only refer to one singleton for sure? Please tell me, does anybody know? Because I dont want to get bad surprises later.

Thanks for your reply. But what if you have three nodes, and MBean A is only deployed on Node 1 and 2, and MBean B is deployed only on Node 2 and 3? When node 1 comes up first, then MBean B will not become active at all because its not running on the master node?

Hi James, Thats exactly what I did, and I can see my service bound to JNDI in the JMX console, my client can fetch the service from JNDI, but then... The lookup is successful, no exception is thrown, but how can you invoke now methods on your mbean?? Because in my code, userManager is null. When I use the object, I get a NullPointerException.

Hi James, Can you please tell me how you bound your MBean to JNDI and how you accessed it in your client application then? Can you please show me some code? I was trying to do the same, but it does not work.

[JBoss-user] [Management, JMX/JBoss] - Registering an MBean in JNDI
I want to register my mbean with JNDI so that a client can retrieve the JNDIName and use the mbean. It works when I use the RMIAdapter instead, but I wanted to try the JNDI way. I bound my mbean to JNDI as follows (jndiname is inmemory/maps/MapTest2: |InitialContext rootCtx = new InitialContext(); |Name fullName = rootCtx.getNameParser().parse(jndiName); |NonSerializableFactory.rebind(fullName, this, true); | And obviously, it could be bound successfully because when I look at the JNDIView list of names, I can see the following: +- inmemory (class: org.jnp.interfaces.NamingContext) | +- maps (class: org.jnp.interfaces.NamingContext) | | +- MapTest2 (class: mytest.mbean.JNDIMap) My client application tries to access the service now as follows: | Object obj = getContext().lookup (inmemory/maps/MapTest2); | mytest.mbean.JNDIMap map = (mytest.mbean.JNDIMap)PortableRemoteObject.narrow(obj, mytest.mbean.JNDIMap.class); | But it does not work. map is null. What is wrong with that code? Can anybody help me?

[JBoss-user] [Management, JMX/JBoss] - Re: Questions about standard MBean Example
Thanks for the reply, but it still does not work. I had already put all these files into the correct directory, but I still get a NoClassDefFound exception when deploying my mbean. But the same code works in my standalone client appliciation. Seems as if JBoss needs a special hint to know where to look for the classes, I dont know. When I add the comm.jar file to my mbean SAR, then it works, but sorry, this cannot be the right way to do so??? What about the MBean access from a client? So you say that its possible to use the MBean directly, without using an adapter, but you dont say how this can be done. Would be nice to know. Please tell me. And what about the HashMap access??

[JBoss-user] [Management, JMX/JBoss] - Questions about standard MBean Example
I have deployed the very simple standard MBean example of the JBoss Administration and Development Book (3.2.3) which binds a HashMap into JNDI, and then I played with it around, but I got some problems. So here are my questions: 1. The HashMap was successfully bound into JNDI, and I can see my service on the JMX console. Then I wrote a client which does a lookup on the HashMap, as follows: map = (HashMap) getContext().lookup(inmemory/maps/MapTest2); Seems to be okay, because I dont get any NamingException. But how can I use the HashMap then? How can I access the content now? When I want to use the map, I get a NullPointerException. Why is it null?? 2. I would like to call functions on my mbean, from a client or another mbean. Do I have to use an adapter for that, or can I access the mbean directly via JNDI?? How can I give my mbean a JNDI name? 3. In the mbeans start() method I tried to create a serial connection to a PLC. But when I deploy the SAR file, the usage of the classes for the serial communication causes a NoClassDefFoundError Exception. But I added the javax.comm package to my Eclipse project, and when I put the same serial port access code into my client application (within the same project), it works and I dont get any exception. So why cant my mbean find these classes? Do I have to add something to the descriptor file?? I would really like to use my mbean...

[JBoss-user] [JCA/JBoss] - Example File System RA
I tried to deploy the JCA example of JBOSS Administration and Development book chapter 7 (File System Adapter) for JBoss 3.2.3, but I always get an Exception. This is what I did: I put the following files (generated by the delivered build.xml) into the deploy directory: chap7-ex1.jar (EJB) chap7-ex1.rar (Resource Adapter) jboss-service.xml notxfs-ds.xml But I always get the following exeption: [MainDeployer] Starting deployment of package: file:/W:/java/jboss-3.2.3/server/default/deploy/jboss-service.xml [ServiceConfigurator] Problem configuring service jboss.jca:service=NoTxFS,name=filesystem org.jboss.deployment.DeploymentException: No Attribute found with name: JndiName at org.jboss.system.ServiceConfigurator.configure(ServiceConfigurator.java:334) at . It seems as if something is wrong with the jboss-service.xml file. But thats the example file of the book. I didnt change it. I didnt change any of the delivered files.
