EJB function selector

Edit online

The EJB bindings use an import function selector (for outbound processing) or an export function selector (for inbound processing) to determine the EJB method to call.

Import function selector

For outbound processing, the import function selector derives the EJB method type based on the name of the operation invoked by the SCA component that is wired to the EJB import. The function selector looks for the @WebMethod annotation on the Integration Designer-generated JAX-WS annotated Java™ class to determine the associated target operation name.
  • If the @WebMethod annotation is present, the function selector uses the @WebMethod annotation to determine the correct Java method mapping for the WSDL method.
  • If the @WebMethod annotation is missing, the function selector assumes that the Java method name is the same as the invoked operation name.
Note: This function selector is valid only for a WSDL-typed interface on an EJB import, not for a Java-typed interface on an EJB import.

The function selector returns a java.lang.reflect.Method object that represents the method of the EJB interface.

The function selector uses a Java Object array (Object[]) to contain the response from the target method. The first element in the Object[] is a Java method with the name of the WSDL, and the second element in the Object[] is the input business object.

Export function selector

For inbound processing, the export function selector derives the target method to be invoked from the Java method.

The export function selector maps the Java operation name invoked by the EJB client into the name of the operation in the interface of the target component. The method name is returned as a String and is resolved by the SCA runtime depending on the interface type of the target component.
