The landlord to add two interfaces to a DLL (c + +), the dynamic invocation in the Java project in eclipse, the first call, the second cannot call,
Error message:

The original poster in c + + write a test project, the dynamic invocation DLL, two interface does not appear problem,
The original poster in Java program debugging has been check to the calling card interface, parameter passing without error, the original poster can't see specific how to call in the Java project, can only follow up to the call to

Additional error information: org. Springframework. Web. Util. NestedServletException: Handler processing failed; Nested exception is Java. Lang. Error: Invalid memory access

The original poster with the depends. Exe view the DLL file can see oneself add two interface
Of the following is a Java interface declaration:
Int SetPIPSingleChannelReplace (String STR, byte [] resStr, int bufflen);//can correct use
Int SetPIPInfo (String STR, byte [] resStr, int bufflen);//in the Java program cannot use
Because the interface format is used, the building Lord think can eliminate type conversion problem,
The original poster is trying to the order of the export file interface, name change, does not work,

The dynamic library is written by C?
