Question about calling ejb3.0 in jobss

Ejb3.0 has been around for a long time. Although you can try it without a practical project, you still want to see its charm. Download jboss4.2-ga to develop ejb3.0's simplicity, it's just as easy as 2.0, saving a lot of xml configuration. This is the first time I feel the strong charm of jdk5.0, its custom annotation has time to study it. however, this experience is not smooth. after JBoss is successfully deployed, the written test program fails to be called, and an exception javax is reported. naming. communicationexception: cocould not obtain connection to any of these URLs: 127.0.0.1: 1099 and discovery failed with error: Java. security. accesscontrolexception: Access Denied (java.net. socketpermission 230.0.0.4 connect, accept, resolve) [root exception is javax. naming. communicationexception: failed to connect to server 127.0.0.1: 1099 [root exception is Java. security. accesscontrolexception: Access Denied (java.net. socketpermission 127.0.0.1: 1099 connect, resolve)] At Org. jnp. interfaces. namingcontext. checkref (namingcontext. java: 1562) at Org. jnp. interfaces. namingcontext. lookup (namingcontext. java: 634) at Org. jnp. interfaces. namingcontext. lookup (namingcontext. java: 627) at javax. naming. initialcontext. lookup (initialcontext. java: 351) at JUnit. debug. ejbfactory. getejb (ejbfactory. java: 34) at JUnit. debug. helloworldtest. setupbeforeclass (helloworldtest. java: 15) at Sun. reflect. nativemethodaccessorimpl. invoke0 (native method) at Sun. reflect. nativemethodaccessorimpl. invoke (nativemethodaccessorimpl. java: 39) at Sun. reflect. delegatingmethodaccessorimpl. invoke (delegatingmethodaccessorimpl. java: 25) at java. lang. reflect. method. invoke (method. java: 585) at Org.

Because the code system was added before the JNDI search. setproperty ("Java. security. policy "," client. policy "); If (system. getsecuritymanager () = NULL) system. setsecuritymanager, no reasonable answer was found. Finally, the JBoss was replaced by the High-point version 5.0, blocking the above security code, and the call was successful. in addition, if a local interface for bean is deployed to version 4.2 and cannot be found in the JNDI tree, you can only find remote. it can be found when it is changed to 5.0. before reading the information said 4.0 to the next jboss-ejb3.0-rc9 ant again, but I did not go down, maybe this problem? I have not demonstrated it yet. there is also a weak knowledge about security, and we will try to fix it in the near future. finally, paste the called code and mark it by yourself. // system. setproperty ("Java. security. policy "," client. policy "); // If (system. getsecuritymanager () = NULL) // system. setsecuritymanager (New rmisecuritymanager (); // properties props = NewProperties (); props. setproperty ("Java. naming. factory. initial "," org. jnp. interfaces. namingcontextfactory "); props. setproperty ("Java. naming. provider.
