Class EJBUtils

java.lang.Object
com.sun.ejb.EJBUtils
public class EJBUtils extends Object
A handy class with static utility methods. Note that much of this code has to execute in the client so it needs to be careful about which server-only resources it uses and in which code paths.

    • serializeObject

      public static final byte[] serializeObject(Object obj, boolean replaceObject) throws IOException
      Utility methods for serializing EJBs, primary keys and container-managed fields, all of which may include Remote EJB references, Local refs, JNDI Contexts etc which are not Serializable. This is not used for normal RMI-IIOP serialization. It has boolean replaceObject control, whether to call replaceObject or not
      Throws:
      IOException

    • serializeObject

      public static final byte[] serializeObject(Object obj) throws IOException
      Throws:
      IOException

    • deserializeObject

      public static final Object deserializeObject(byte[] data, ClassLoader loader, boolean resolveObject) throws Exception
      Utility method for deserializing EJBs, primary keys and container-managed fields, all of which may include Remote EJB references, Local refs, JNDI Contexts etc which are not Serializable.
      Throws:
      Exception

      Throws:
      Exception

    • useStaticCodegen

    • getGeneratedOptionalInterfaceName

      public static String getGeneratedOptionalInterfaceName(String ejbClassName)
      Prepends __EJB31_Generated__ and adds _Intf__ to the simple class name.
      Parameters:
      ejbClassName - full class name

    • getRemoteEjbJndiName

      public static org.glassfish.api.naming.SimpleJndiName getRemoteEjbJndiName(com.sun.enterprise.deployment.EjbReferenceDescriptor refDesc)
      Actual jndi-name under which Remote ejb factory lives depends on whether it's a Remote Home view or Remote Business view. This is necessary since a single session bean can expose both views and the resulting factory objects are different. These semantics are not exposed to the developer-view to keep things simpler. The developer can simply deal with a single physical jndi-name. If the target bean exposes both a Remote Home view and a Remote Business view, the developer can still use the single physical jndi-name to resolve remote ejb-refs, and we will handle the distinction internally. Of course, this is based on the assumption that the internal name is generated in a way that will not clash with a separate top-level physical jndi-name chosen by the developer. Note that it's better to delay this final jndi name translation as much as possible and do it right before the NamingManager lookup, as opposed to changing the jndi-name within the descriptor objects themselves. This way, the extra indirection will not be exposed if the descriptors are written out and they won't complicate any jndi-name equality logic.
