Let me get my understanding here correct My understanding is ..... Remote is when client calls from a different JVM environment to a Bean which is in a seperate JVM. This is where Calls By Value comes in as everything has to be copied (part of serailization) to be sent across the wire. Where as Local means when both Client and Beans are in same JVM which means Call by reference is used. You can enlighten me please if this is wrong or nor correct. As to this error i thought i could change the setting in conf/standrdjboss.xml file where invoker proxy binding settings are. | | <invoker-proxy-binding> | <name>entity-rmi-invoker</name> | <invoker-mbean>jboss:service=invoker,type=jrmp</invoker-mbean> | <proxy-factory>org.jboss.proxy.ejb.ProxyFactory</proxy-factory> | <proxy-factory-config> | <client-interceptors> | <home> | <interceptor>org.jboss.proxy.ejb.HomeInterceptor</interceptor> | <interceptor>org.jboss.proxy.SecurityInterceptor</interceptor> | <interceptor>org.jboss.proxy.TransactionInterceptor</interceptor> | <interceptor call-by-value="false">org.jboss.invocation.InvokerInterceptor</interceptor> | <interceptor call-by-value="true">org.jboss.invocation.MarshallingInvokerInterceptor</interceptor> | </home> | ----- | and some for others as in this category | | ----- | </client-interceptors> | </proxy-factory-config> | </invoker-proxy-binding> | | I'm not sure in this version of JBoss which option to modify yet as currenty InvokerInterceptor is set to call by value, where as if i go by my understanding than if i change it to false than it should work as my client for both Remote and Local are in same JVM.
