Content decompress (Base64 + Zlib)

I wanted to decompress data getting send to GSA (google search appliance) to verify the actual content. Google Search Appliance uses Base64 encode and Zlib compress technique which improves performance, because less data is sent across the network.

Here is link on GSA Content Compression: https://www.google.com/support/enterprise/static/gsa/docs/admin/72/gsa_doc_set/feedsguide/feedsguide.html#1074587

There is api provides by Java that can be used to  compress and decompress data using the java.util.zip package. - http://www.oracle.com/technetwork/articles/java/compress-1565076.html

To decode base64 string you can use class org.apache.commons.codec.binary.Base64 provided by apache commons library.

code snippet that follows:  
String string = "SmF2YWNvZGVnZWVrcw==";
// Get bytes from string
byte[] byteArray = Base64.decodeBase64(string.getBytes());
// Print the decoded array
System.out.println(Arrays.toString(byteArray));

To decompress zlib content you can use Java Byte Array Using Inflater
code snippet that follows: 
public static byte[] decompress(byte[] data) throws IOException, DataFormatException {
    Inflater inflater = new Inflater();  
    inflater.setInput(data); 
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream(data.length); 
    byte[] buffer = new byte[1024]; 
    while (!inflater.finished()) { 
        int count = inflater.inflate(buffer); 
        outputStream.write(buffer, 0, count); 
    } 
    outputStream.close(); 
    byte[] output = outputStream.toByteArray(); 
    LOG.debug("Original: " + data.length); 
    LOG.debug("Compressed: " + output.length); 
    return output; 
}

How to enable remote debugging for a WebSphere Web application using RAD

Step 1:

To be able to debug an Enterprise Application you must enable the Debugging service for WebSphere Application server.

Ensure you set up an appropriate port that the development client is able to access.

Things to remember here :

1)       You must start server is debug mode either by selecting ‘Enable service at server startup’ or by using RAD

2)       Take a note of JVM Debug port

Step 2:

Using RAD (IBM Rapid Application Developer)

Switch to Debug Perspective

Open Debug configurations and Set-up remote debug details using appropriate port as set in the Application server's Debugging service.

Note: If you get this dialog, it is because the server is not started or you have a firewall issue or incorrect connection details.

Finally Set a break point on deployed web project.
