Hello,

I searched the mailing list archive, but I didn't find anything helpful.

I have a problem calling a C++ function.

Here is the part of the header-file:

#define DCSLoadBalancer_Handle void* DCSLoadBalancer_Handle DCSLoadBalancer_FormatDocument (void* pDCSLoadBalancer,
void* pData, long lData, char* pPool, DCSLoadBalancer_Handle hProcessID, void*
callbackfunction, void* pParam)

In my interface I declared the function:

Pointer DCSLoadBalancer_FormatDocument(Pointer pDCSLoadBalancer, String
pData,long lData, String pPool, Pointer hProcessID, Pointer callbackfunction,
Pointer pParam);

Now when I call:

String pPool = ... String xmlString = ... Pointer hDocID =
DCSLBLibrary.INSTANCE.DCSLoadBalancer_FormatDocument(pDCSLoadBalancer,
xmlString, xmlString.length(), pPool, null, null, null);

I get an error because the null pointer of hProcessID (5th parameter) doesn't
reach the C++ function. The parameter hProcessID in the C++ function
DCSLoadBalancer_FormatDocument gets an address.

What happens with this pointer object between the java call and the c++ call?

Can anybody help me?

Thanks in advance! Chris
