Well,my cluster hans two node.each node has deployed a "hello world" ejb.
i write a client to test cluster.
the main content of client like:
| Properties props =new Properties();
|
props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
| props.put(Context.URL_PKG_PREFIXES,"jboss.naming:org.jnp.interfaces");
| props.put(Context.PROVIDER_URL,"10.40.90.164:1100,10.40.59.8:1100");
|
| Context context = new InitialContext(props);
|
| Object ref = context.lookup("hello");
|
| helloHomeObject = (helloHome) PortableRemoteObject.narrow(ref,
helloHome.class);
|
|
while first i use
| int round = 10;
|
| hello hello=helloHomeObject.create();
| while(round > 0 ){
| hello.helloworld();
| round--;
| }
|
|
but i only see server 10.40.59.8 print"hello world" ten times.
the second i use
|
| int round = 10;
|
| while(round > 0 ){
| hello hello=helloHomeObject.create();
| hello.helloworld();
| round--;
| }
|
also the same result.
but if i shutdown the server10.40.59.8,server10.40.90.164 can finish the job.
it seems like i only implement fail-over but not load-balance.
i use jboss3.0.3,and did not modify any configure file of server.my ejb jboss.xml like
this:
| <jboss>
| <enterprise-beans>
| <session>
| <ejb-name>hello</ejb-name>
| <jndi-name>hello</jndi-name>
| <local-jndi-name>helloLocal</local-jndi-name>
| <clustered>True</clustered>
| <cluster-config>
| <partition-name>DefaultPartition</partition-name>
| <home-load-balance-policy>
| org.jboss.ha.framework.interfaces.RoundRobin
| </home-load-balance-policy>
| <bean-load-balance-policy>
| org.jboss.ha.framework.interfaces.RoundRobin
| </bean-load-balance-policy>
| </cluster-config>
| </session>
| </enterprise-beans>
| </jboss>
|
who can tell me where i am wrong? thanks a lot.
