[SOLVED] Is this possible to convert EBCDIC Comp-3 file to ASCII file values using java?

Is this possible to convert EBCDIC Comp-3 file to ASCII file values using java?

I am trying to convert the EBCDIC COMP-3 fields to ASCII values but which is not working.But Binary COMP-3 fields could be converted to ASCII values.Please help me to understand is this possible or not? Even using any other java library is ok for me.I tried and searched may but no concrete answer I could see.

Update:

In my previous one binary should be the one which will work.This what I received as answer but there was no clarity about EBCDIC COMP-3.

Solution

There is no such thing as an "EBCDIC COMP-3 field", and it has no equivalent in ASCII code points. It is a binary format. So understand you have a record mixed of character and binary formats.

Comp-3 is packed decimal. It can vary a bit on different machine architectures as to where they put the sign nibble and whatnot, but it is a binary format, so any attempt to convert it using character set rules will always fail.

The easiest way to deal with this, by far, is to convert any packed decimal data to a display format, made up of characters. So instead of x'0123456C', you actually convert that to c'01234.56', and then your standard EBCDIC to ASCII conversion will work fine.
