Dear Jawin-users ,
we are developing a Java application, which needs to communicate with a
special german windows-based tax software (Stotax) via COM. We are
evaluating Jawin for doing this job and wrote a little test programm (code
snippet follows). Via JTB we generated the stubs IFDXComInterface.java and
FDXComInterface.java.
***************************************
try {
Ole32.CoInitialize();
IFDXComInterface.init();
IFDXComInterface sif = new IFDXComInterface
("SNGFDXICOM.FDXComInterface.1");
console.append("\n" + sif.queryInterface(sif.getClass()));
// this shows: "com.stotax.IFDXComInterface[0,184abbd0]"
// GetProjectName is a function from the COM-interface
Variant pn = sif.GetProjectName();
Ole32.CoUninitialize();
} catch (Exception e) {
e.printStackTrace();
}
***************************************
Executing this program results in the following error:
The VM crashes and gives the following message:

What does this error message indicate in detail?
What can we do to make Jawin work with our COM interface? It would be
helpful, if somebody could supply an example how COM objects besides the
typical Microsoft ones are used. Is the above stated code correct? Eclipse
does not give any errors or warnings when compiling.
Thanks in advance for helping!
