[JBoss-user] [Clustering/JBoss] - problem calling a remote ejb from a servlet in a cluster env
I've three jboss instances on different machine in the same network: 1. Jboss (A) running a web application 2. Jboss (B) running some ejbs 3. Jboss (C) running some ejbs Jboss (B) and Jboss (C) are in the same partition. In a servlet, running in the first jboss intance (A), I call an ejb deployed in the cluster (B,C) using autodiscovery (using jnp.port, jnp.partitionName etc..). You suppose the Jboss C responds to this call (made from servlet). If the server C goes down the next call to this ejb throws this error : java.rmi.ConnectException: Connection refused to host: serverC; nested exception is: java.net.ConnectException: Connection refused at sun.rmi.transport.tcp.TCPEndpoint.newSocket()Ljava.net.Socket;(Optimized Method) at sun.rmi.transport.tcp.TCPChannel.createConnection()Lsun.rmi.transport.Connection;(Optimized Method) at sun.rmi.transport.tcp.TCPChannel.newConnection()Lsun.rmi.transport.Connection;(Optimized Method) at sun.rmi.server.UnicastRef.invoke(Ljava.rmi.Remote;Ljava.lang.reflect.Method;[Ljava.lang.Object;J)Ljava.lang.Object;(Optimized Method) at org.jboss.invocation.jrmp.server.JRMPInvoker_Stub.invoke(Lorg.jboss.invocation.Invocation;)Ljava.lang.Object;(Optimized Method) at org.jboss.invocation.jrmp.interfaces.JRMPInvokerProxy.invoke(Lorg.jboss.invocation.Invocation;)Ljava.lang.Object;(JRMPInvokerProxy.java:118) at org.jboss.invocation.InvokerInterceptor.invokeInvoker(Lorg.jboss.invocation.Invocation;)Ljava.lang.Object;(InvokerInterceptor.java:227) at org.jboss.invocation.InvokerInterceptor.invoke(Lorg.jboss.invocation.Invocation;)Ljava.lang.Object;(InvokerInterceptor.java:167) at org.jboss.proxy.TransactionInterceptor.invoke(Lorg.jboss.invocation.Invocation;)Ljava.lang.Object;(TransactionInterceptor.java:46) at org.jboss.proxy.SecurityInterceptor.invoke(Lorg.jboss.invocation.Invocation;)Ljava.lang.Object;(SecurityInterceptor.java:55) at org.jboss.proxy.ejb.StatelessSessionInterceptor.invoke(Lorg.jboss.invocation.Invocation;)Ljava.lang.Object;(StatelessSessionInterceptor.java:97) at org.jboss.proxy.ClientContainer.invoke(Ljava.lang.Object;Ljava.lang.reflect.Method;[Ljava.lang.Object;)Ljava.lang.Object;(ClientContainer.java:86) Anyone could help me ?

I've forgot that the problem displayed in the JVM console is : kgefec : fatal error 0 kgepop : no error frame to pop for error 21503 Could be the Oracle OCI driver for 9.2.0.4 ?

[JBoss-user] [HTTPD, Servlets & JSP] - Urgent OutOfMemory!!
How to verify what objects are not removed (finalized) from JVM ? My JVM has an heap of 1024Mb and my application should not store a lot of data, but after some days (2,3..) Jboss crash with an out of memory error. All my classes seam to be safe, without static members or referenced objects. Can anyone help me ?

[JBoss-user] [Clustering/JBoss] - Re: Strange behaivour of jboss cluster
Multihomed means that : Each ServerA and ServerB has two jboss instances with different Ip address binded. Ex.: Server A ==> two Ip Alias : 192.168.10.186, 192.168.10.188 First Jboss Instance 192.168.10.186 jboss.bind.address Second Jboss Instance 192.168.10.188 jboss.bind.address Server B ==> two Ip Alias : 192.168.10.187, 192.168.10.189 First Jboss instance 192.168.10.187 jboss.bind.address Second Jboss instance 192.168.10.189 jboss.bind.address Each First JBoss instance of ServerA and Server B forms a Cluster in the DefaultPartition with the same multicast ip address and group (HAJndi 1100). Each Second Jboss instance of Server A and Server B forms another Cluster in MyPArtition with the same multicast ip address and group but different from the first Jboss instance HAJNdi 1101 BEST regards.

[JBoss-user] [Clustering/JBoss] - Strange behaivour of jboss cluster
Hi all,
I have two Host (A,B).
Each host has a multihomed Jboss installation.
Server A : Address ipA1, Address IpA2
Server B : Address ipB1, Address IpB2
Server A : Jboss1, Jboss2
Server B : Jboss1, Jboss2
Each Jboss1 is in the same cluster.
Jboss2 are another cluster.
My jboss version is 3.2.2.
Jboss1 contains a j2ee application and hosts some ejbs (Stateless EJB)
Jboss2 contains only ejbs (Stateless EJB).
In a JSP page I do two lookups : one for an EJB hosted by Jboss1 and
one for an EJB hosted by Jboss2. Jndi query are cached.
If I stop Jboss2, sometimes I get Service unavalible in the stack trace.
But this happends only for ejbs of Jboss2.
My jndi lookup looks like this :
p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL,"ipA1:1101,ipA2:1101");
p.put("jnp.partitionName","myPartition");
p.put("jnp.discoveryGroup","224.10.10.10");
p.put("jnp.discoveryPort","1103");
Moreover, Jboss1 and Jboss2 have different Partition and Multicast
address. Each Jboss is started with --host option.
Anyone can help me ?
BEST REGARDS
