Hi, Is there a Base64 method from J2SE 1.4 API that can decode and encode a string? TIA.

I read a claim that there was a method in java.util.prefs, but otherwise it seems like people have just gone and made their own classes and/or methods. I've also head that there is an undocumented method called sun.misc.BASE64Encoder.encode.

Anyway, if you want some Base64 encoding/decoding I suggest you either make your own class to handle it, or download any of the ones you find by googling for java base64.

Use Commons Codec from Apache Site
http://jakarta.apache.org/commons/codec/

in package org.apache.commons.codec.binary
there is one class Base64

use static method :
* decodeBase64(byte[] base64Data)
* encodeBase64(byte[] binaryData)
* and be careful it works in array of bytes not String
* so beware of character encoding for Converting between your String to array of bytes.

Hopes this help you.
