hi, am giving the code also and explained in detail...
i have 4 nodes in a cluster, when i deploy my webservice in one of the nodes
and the EJB's in the other 3 nodes it seems to be working fine, the load is
balanced(i.e when i send 50 requests they are split to the 3 nodes etc) ,
failover happens fine..
but when i have the EJB in all 4 nodes (including the one with the webservice)
and then clustering doesnt happen. all requests are routed to the ejb present
in the same node as the webservice ???
first case:
node 1 - web service(wsr)
node 2 - ejb
node 3 - ejb
clustering,failover working fine, all requests are sent to node2 and node 3
second case:
node 1 - web service(wsr) & ejb
node 2 - ejb
node 3 - ejb
all requests sent to ejb in node1 itself, nothing sent to node 2 and 3
there shud be some configuration i shud add in jboss.xml or somewhere to forbid
this??? i have around 6 services like this and it wud require lot of machines
if webservice and ejb cant be deployed in the same node..
lookup code:
if ( !isValidUser ){
_responseString = " User Not Authenticated";
return _responseString;
}
Context context = new InitialContext( _jndiProperties );
Object objref = context.lookup( "UserObjectsEJB" );
NBUserObjectServiceHome userObjectHome = ( NBUserObjectServiceHome
)PortableRemoteObject.narrow( objref, NBUserObjectServiceHome.class );
NBUserObjectServiceRemote userObjectRemoteInterface = userObjectHome.create();
_responseString = userObjectRemoteInterface.serviceRequest( userId_,
requestString_ );
System.out.println ( "NBWUserObjectService.serviceRequestEJB() The Response is
:: " + _responseString );
return _responseString;
jboss.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS//EN"
"http://www.jboss.org/j2ee/dtd/jboss.dtd";>
<enterprise-beans>
<ejb-name>UserObjectServiceEJB</ejb-name>
<jndi-name>UserObjectsEJB</jndi-name>
true
</enterprise-beans>
this method is called just be4 the context is created...
method:
try{
Hashtable _jndiProperties = new hashtable();
_
_jndiProperties.put(
Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory" );
_jndiProperties.put( Context.PROVIDER_URL, "10.1.30.57:7070" );
_jndiProperties.put(
Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces" );
}catch( Exception exc_ ){
exc_.printStackTrace();
}
