COM4J throws exception - VB.Net DLL

[grahamengland]

I have a common library of about 150 functions created in VB.Net (compiled COM DLL) which I'm trying to open up to Java using com4J, but when I submit the command line entry (java -cp . -jar tlbimp.jar -o DLL2JAR -p CommonDLL c:\factory\graham_net\Graham_Net.dll) I get the following exception error…
Exception in thread "main" com4j.ExecutionException: com4j.ComException: 80029c4

@johnson-yeap - No, so I decided to convert my VB.Net code to Java instead. I'm using a great tool to help in this process - the "VB to Java Converter" from Tangible...
