You need to obtain the PipeParser from the HapiContext where you attached
the ModelClassFactory to.
ModelClassFactory cfm=*new* CustomModelClassFactory("com.hss.customodel");
HapiContext context=*new* DefaultHapiContext(cfm);
Parser pipeParser = context.getPipeParser();
Message m=pipeParser.parse(ackMessageString);
System.*out*.println("My message is "+m.printStructure());
Now the Parser should use your custom structures.
