Re: org.jawin.COMException: 8002802b: Element not found.

Thanks for the quick response.

Here is the test method I use to call everything.  It is very simple and it
is basically the same as the one in the documentation.  The method that I
was trying to use is openConnection(String,String) but to test it I am using
a couple of differnt version methods for simplicity as you also suggested. I
did remember to use the CoInitalize.

public void testMe() throws Exception

{

Ole32.CoInitialize();

IRequestProcessor2 rqProcessor = new
IRequestProcessor2("QBXMLRP.RequestProcessor");

System.out.println("Testing");

short tmp = rqProcessor.getReleaseNumber();

System.out.println(tmp);

short tmp = rqProcessor.getMajorVersion();

System.out.println(tmp);

System.out.println("TestDone");

Ole32.CoUninitalize();


The library that it is trying to run on is a QuickBooks library so it may be
difficult for you to do anything with it.  I can put the classes that Type
Browser creates on a server so you can see them, if that would help.  They
are, obvioulsy, just stubs so they are pretty simple as such
public short getReleaseNumber() throws COMException

{

return ((Short)get("ReleaseNumber")).shortValue();

}



The stack trace is as follows:

org.jawin.COMException: 8002802b: Element not found.

        at testFile.<init>(testFile.java:25)
        at testFile.main(testFile.java:41)


I am trying to figure out what is failing by looking at the jawin source but
I cant seem to get a handle on it.  I dont really understand what all is
going on yet.
