I tried many ways to get this fixed... but it didnot help me. I meddled with the jboss-service.xml file under \all\deploy\ejb3.deployer\META-INF folder by setting socket://${jboss.bind.address}:3873/?maxPoolSize=600 maxPoolSize=600 attribute, which didnot work. I also changed my standardjboss.xml file under \all\conf folder for maximum pool size of by stateless session beans.. <container-configuration> | <container-name> | Standard Stateless SessionBean | </container-name> | <container-pool-conf> | <MaximumSize> | 150 | </MaximumSize> | </container-pool-conf> | </container-configuration> which didnot work... I am making only local calls to my EJBs (3.0) , so what invokers will be involved in the calls and where can I alter them???
