Abstract: A Java Virtual Machine (JVM) is enabled to process a data object in common storage. After the data object is received in an address space of an application, an anchor is created in common storage for the data object and the data object is copied into common storage via a Program Call (PC) routine. A notification received at a JVM via a Java Native Interface (JNI) indicates that the data object has been created in the address space of the application and includes a pointer to the data object in common storage. The JVM process, via a Java thread of the JVM, processes the data object in common storage. Upon the Java thread completing processing of the data object, a response is communicated, via the JNI, to a native thread of the JVM. The native thread of the JVM transfers control of the data object back to the PC routine.
