Re: Error generating java stubs for mshtml

Thanks for your reply Josh.

Looking at the code, the problem is not an unsupported type.

The problem occurs in:
       int err = iTypeInfo.getRefTypeInfo(typeDesc.hreftype,
userDefinedType);
which returns a value of  80070057 (E_INVALIDARG).

The next line
       if (HRESULT.FAILED(err)) {
           throw new RuntimeException(new COMException(err).toString());
tests whether the MSB of err is set and throws the exception.

So the problem is occurring  in the call to ITypeInfo.getRefTypeInfo().
This is a native method, and I can only follow the logic as far as the
C++ wrapper, where the "err" value is set in
src/com/develop/jawin/win32/com_develop_jawin_win32_ITypeInfo.cpp, line 241:
       returnType=(jint)pTypeInfo->GetRefTypeInfo((long)hRefType,
&pRefTypeInfo);

So GetRefTypeInfo, which is a win32 library function, is returning the
E_INVALIDARG. Unfortunately, I can't tell what arguments are being
supplied. My next step will be to try and add some debug to get more
detailed info and build the package myself. But I was hoping someone
else might have tackled this before :)
