Question

How can I overcome the string size limitation.

It seems that calling decode on Strings of size greater than 64k fails.

        is = con.openInputStream();
        String str = new String(IOUtilities.streamToBytes(is), "UTF-8");
        byte[] theArray = Base64InputStream.decode(str);  

Ive tried alsorts, including using

        Base64InputStream bs64 = new Base64InputStream(is);

And then trying to take from the bs64 stream.

It seems however, reading a large size leads to decode error. (Where it wouldnt error if size below 64k the origional way. I spent all day trying to figure this one..

Answer 1

You can decode your string in smaller chunks. Decode chunks of 3 bytes or a multitude of 3 bytes (1024 will do nicely) at a time.
