Hi everybody,=0A=0AI am a university student and I am working in a telecomu=
nication company.=0AI am searching more than one week for an open source a=
sn.1 to java parser/compiler and I found cryptix's asn.1 tool..=0AThis tool=
is for DER docoding/ encoding=0ABut I want to do BER processing.. I want t=
o use cryptix for only parsing my asn.1 input file which is a text file and=
includes some asn.1 definitions like :=0A=0AExampleProtocol DEFINITIONS :=
:=3D=0ABEGIN=0A ExampleProtocolMessage ::=3D CHOICE {=0A =0A =
rlcGeneralBroadcast RlcGeneralBroadcast,=0A }=0A RlcGeneralBr=
oadcast ::=3D [APPLICATION 0] SEQUENCE {=0A =0A d=
uplexMode DuplexMode,=0A fr=
ameOffset FrameOffset,=0A=0A } =0A Dupl=
exMode ::=3D ENUMERATED {fdd(0), tdd(1)}=0A FrameOffset =
::=3D INTEGER (0 | 8..20)=0A=0AEND=0A=0AIn the cryptix-asn1 tool it is =
writing that open source SableCC(a compiler compiler tool) is used for pars=
ing and there is a file "ASN1-004.grammar" which icludes the asn.1 language=
definitions in BNF format to use in SableCC(at least I think so..) I am no=
t sure about this.. =0AI tried to look the source code very closer but it i=
s still not clear in my mind.. Can I use this asn.1 tool (or the grammer f=
ile : "ASN1-004.grammar") to parse my asn.1 input file ? (at the end, I wan=
t to generate java classes of the data types which are defined in the input=
file)=0A(then later I may write my own BER encode/decode methods..)=0A=0AC=
an anyone please help me about that ? =0A=0AThanks=0ABest regards=0AFatih=
