How to decompress String in Java which is compressed in VBA using zlib

Question

We are working on a VBA project. In that project we compress the string using zlib.dll and send request to the server. On the server we can't decompress that buffer.

following code which i used in java to uncompress the string

 public static String decompress(byte[] str) throws IOException {
     ByteArrayInputStream bais = new ByteArrayInputStream(str);
        InflaterInputStream iis = new InflaterInputStream(bais);

        String result = "";
        byte[] buf = new byte[5];
        int rlen = -1;
        while ((rlen = iis.read(buf)) != -1) {
            result += new String(Arrays.copyOf(buf, rlen));
        }

        // now result will contain "Hello World!"

        System.out.println("Decompress result: " + result);
        return result;
    }

My Question is how can I decompress the string on the server in Java?

Answer 1

The package java.util.zip provides classes to manage compressed data. java.util.zip.Inflater may be useful in your case.

Hope it helps.
