Create H.225 java parser

Hi all coders. I need a custom class able to parse H.225/H.245 binary messages into a simple fieldset that i can use in future. H.225/H.245 is ASN.1 PER based protocol used in IP telephony. There are lots of ASN.1 to java compillers, but i have no time to mess with them. You can use any code you'll find or auto generate from .asn file using that compiller. I can proveide you .asn files and samples of binaru messages to be parsed upon request. This is urgent project, so only qualified coders please. Thanks, Alex.
