Add an operation "getMsg" takes "name" as parameter and returns a string.

Deploy this application to Appserver.
Now Create a Mobile application.
Add "Mobile Client to Web Application"
Select "getMsg" operation

Observe the generated code has an error.
Open Utility.java in webapplication.
...
   protected static Object readObject(DataInput in) throws IOException {
        short type = in.readShort();
        Object result;
        switch (type) {
        case STRING_TYPE:
            result = ;
            return result;
        case NULL_TYPE: /* null */
            return null;
        default:
            throw new IllegalArgumentException(
                    "Unsupported return type (" + type + ")");
        }
    }
}
...

Check the line "result =;"
There is no value on right side.

Open WebService.java in Client code observe the same.

   private static Object readObject(DataInput in) throws IOException {
        int type = in.readShort();
        int length;
        Object result;
        switch (type) {
        case 1:
            result = ;
            return result;
        case -1: /* NULL */
            return null;
        }
        throw new IllegalArgumentException("Unsupported return type (" + type + ")");
    } 
}
