Dear All,
My web.xml is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID">
    <display-name>Reports</display-name>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>
    <context-param>
        <param-name>db_driver</param-name>
        <param-value>oracle.jdbc.driver.OracleDriver</param-value>
    </context-param>
    <context-param>
        <param-name>db_server</param-name>
        <param-value>192.168.31.41</param-value>
    </context-param>
</web-app>

I able to acess it in the JSP using
ServletContext context = getServletContext();
String driver = context.getInitParameter("db_driver");
String server = context.getInitParameter("db_server");

I have also written a Java class in the Web App as:

import java.sql.*;
public class DBUtils {
    public DBUtils() {
    }
    public static Connection getDBConnection(String driver, String
conn_url,
            String db_username, String db_password) throws Exception {
        Class.forName(driver).newInstance();
        Connection con = DriverManager.getConnection(conn_url, db_username,
                db_password);
        return con;
    }
}

I can get DB connection for the JSP using this:
con = DBUtils.getDBConnection(driver, conn_url, username,
db_password);

But then i have to depend on the external parameters from JSP.

Can i access the context parameters in the java class?
As i checked ServletContext is not getting resolved in the java class
Any way to access the data from web.xml in java class?

Please revert.
