Base64 Encoding / Decoding Assistance.
I have a String which has already been base64 encoded. Now when this is marshalled in weblogic is get encoded again - which i dont want, So i which to decode the orignal base64 but yet keep it in a String format.
Is this possible ?
How do i do it ?

String image //already base64'd
Base64 imageBase64 = new Base64();
//currently
if (image != null) {
ImageData.setImageData(image.getBytes());
}
//attempting
if (image != null) {
String newImage = image converted from base64 back to a String
ImageData.setImageData(newImage.getBytes());
}

I probably didnt explain myself propery.
The string i have is already base64 encoded, I then do ImageData.setImageData(ima
When i look at this data i can see it has been encoded twice as i have used services like http://www.motobit.com/util/base64-decoder-encoder.asp to unencode and the data is the same as the original String.
If i do getByte i get a byte representation of String
Does that make sense ?

apologies i also meant to add : given the String that has been encoded twice I can decode it via
http://www.motobit.com/util/base64-decoder-encoder.asp and then with unencoded string i can decode it again http://www.4mhz.de/b64dec.html back to binary and then view the image.

So double encoded String -> http://www.motobit.com/util/base64-decoder-encoder.asp -> http://www.4mhz.de/b64dec.html = .jpg
In my code i have a base64 encoded String which i can paste into this tool http://www.4mhz.de/b64dec.html to give me a jpg.
Currenly i have :
String image //already base64'd
if (image != null) {
ImageData.setImageData(ima
}
So in theory i need to do a getBytes on the decoded String, i'd guess decoding the String would give me some kind of blob in with which i need to call getBytes on ....
Does that sound correct ? How do i implement this ?
Any help greatly appreciated

Base64 *de*coding something encoded will already give you a byte array which you can use to set the image

Could you show me an example please ?
Thanks
Thanks
Can you tell me which Base64 class you're using?

Hi
import org.apache.commons.codec.b
I think I may have worked it out, just in the process of trying to prove it. The message is pushed onto a JMS queue, so I am just logging that.

Yeah i had something like that. Thanks
Managed to log the JMS queue as well, and it all looks good.

Not really - since it wouldn't need Base64 encoding if it were a real string. Why can't you decode it as byte[]
