I am using JNI to call a Com component. The Com component works fine except for one method which throws a _com_error with a HResult of 0x8000ffff (E_UNEXPECTED). When called from a C++ console application, this method works fine. My jni dll executes *exactly* the same code as the C++ program: both call a parameterless test() function that sets up com, creates the Com object and calls the methods. What could cause the method to fail when called from a Java? Details - jdk1.3.1_01 - In my Dll, I use the #import directive and the Smart Com wrappers - Apartment threaded or Multithreaded initialization makes no difference. Both work from c++

Details
- jdk1.3.1_01
- In my Dll, I use the #import directive and the Smart Com wrappers
- Apartment threaded or Multithreaded initialization
makes no difference. Both work from c++ and fail from Java.
- Increasing the Java thread stack (-Xss1M) made no difference.
