>From your output, it looks like your EntityResolver is being called and all of that is fine. The publicID would be supplied by the parser if your !DOCTYPE declaration used the PUBLIC form of the externalID. However, your document uses the SYSTEM form and that is exactly what is being passed.
So, I think your DTDResolver is basically fine. You have some cleanup to do. Your "if" statement checks this.dtdLocation but your message reports on publicID. But it is basically fine. This brings us to your transformation itself. I don't understand what you're doing with the source.setSystemId() call. It sounds like you're saying that the source and DTD both have the same name. Try changing the name on the setSystemId() call and see if the error message still refers to SonyDAMAssetMetadata.dtd. If so, it means that the parser just can't find your DTD. Also try changing the URL you're passing into setDTDLocation and see how this affects your error messages. Have you tried the transformation from the command line to make sure it works at all?
