I desigend a J2EE Aplication using JSP and Servlets in MVC design.
My system was working great untill i tried using filter for gzip compression for response output , after i used filter gzip, my whole application is destroyed, I cannot able to connect to my Mysql data base, my connection object always returns NULL, i tried every thing re-installing the mysql driver, re-installing the NetBeans ide , nothing is working, i am not able to connect with the database.

This application was working perfect before i experimented with the Gzip filter.please any body can help me what i did wrong, did i corrupted tomcat server. My application is still on my laptop and is not have been loaded on internet yet. i am posting some errors it is showing on the tomcat log.

I Want to mention i am using connection pooling which was working great,
all the servlets are present in the application, the whole application and connection pooling was working great before i used this gzip filter.....Also i like to mention the main problem is when i try to load the driver for Mysql database in my java class it always returns a null connection object. I use Class.forName function in java to load a driver for mysql database.Following is the code where my appliacation returns null connection object

public static Connection ConnectDB(String NameParm, String PasswordParm) {
try {

String url = "jdbc:mysql://localhost:3306/mysql";

Class.forName("com.mysql.jdbc.Driver");
conn = null;
conn = DriverManager.getConnection(url, NameParm, PasswordParm);
System.out.println("Database connection established");
return conn;
} catch (Exception e)
{
System.err.println("Cannot connect to database server ");
return conn;
}
}

please guilde me.. my application is totally stoped at this moment.
