How to get clustered JNDI context with in a servlet to look up an EJB in JBoss 5.0.1 GA cluster ?
I have created two nodes in Jboss cluster. I have deployed an EAR containing EJB Jar and a web application WAR.
When I try to look up the EJB from a stand alone client, my request is getting processed by the EJB's evenly . Means.., if I make 3000 requests, 1500 requests are getting processed by each node.
How ever the same behavior is not seen when I make a call to the EJB from a servlet. (http://<host>:port/ <WebContextRoot>/Servet
Code snippet in standalone client:
private MyUtilBeanRemote getMyUtil() throws NamingException {
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES, "jboss.naming:org.jnp.interfaces");
// HA-JNDI is registered under the partition name passed to JBoss via -g
String bindAddress = System.getProperty("jboss.bind.address", "172.25.129.81");
p.put(Context.PROVIDER_URL, bindAddress + ":1100"); // HA-JNDI address and port.
String partitionName = System.getProperty("jboss.partition.name", "HPPCluster");
p.put("jnp.partitionName", partitionName);
Context ctx = new InitialContext(p);
MyUtilBeanRemote remote = (MyUtilBeanRemote)ctx.lookup("ejb/MyUtil");
return remote;
}
Code snippet in Servlet:
------------------------------------
private MyUtilBeanRemote getMyUtil() throws NamingException {
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES, "jboss.naming:org.jnp.interfaces");
// HA-JNDI is registered under the partition name passed to JBoss via -g
//String bindAddress = System.getProperty("jboss.bind.address", "172.25.129.81");
p.put(Context.PROVIDER_URL, "172.25.129.81:1100");
//p.put(Context.PROVIDER_URL, bindAddress + ":1100"); // HA-JNDI address and port.
String partitionName = System.getProperty("jboss.partition.name", "DefaultPartition");// Even tries with HPPCluster which is my name of the cluster
p.put("jnp.partitionName", partitionName);
Context ctx = new InitialContext(p);
MyUtilBeanRemote remote = (MyUtilBeanRemote)ctx.lookup("ejb/MyUtil");
return remote;
}
JBoss configurations done:
Copied the all distribution as node 1 and node 2 on same machine .
Used the following commnds to start the cluster nodes;
run.bat -c node1 -g HPPCluster -u 239.255.100.100 -b 172.25.129.81 -Djboss.messaging.ServerPeerID=1 -Djboss.service.binding.set=ports-default
run.bat -c node2 -g HPPCluster -u 239.255.100.100 -b 172.25.129.81 -Djboss.messaging.ServerPeerID=2 -Djboss.service.binding.set=ports-01
Is there any additional steps which I have missed out for cluster configuration in JBoss 5.0.1 GA ?
