Hi Fatih, There is no "parser text'" that reads ASN.1 notation in the ASN.1 framework. I think it would be nice to have it developed - that would make easier to implement protocols based on ASN.1 > I want to generate .java classes of types which are defined in my asn.1 > protocol(which is a text file). > Then I want to make encode and decode operations by use of instances of these > .java classes.

The ASN.1 is used for quite long time and I think that there should be a number of existing parsers for ASN.1 (it may be worth to find and try them first).

If ok, can you show me where it is ..?
