You can easily figure out flaws in the earlier approach the authentication should be done at early stage because we cant recover from it. Although the target database system is MySQL the same technique can be applied for other database systems as well because the query syntax used is standard SQL which is supported by all relational database. But to run the JDBC programs the JDBC drivers JAR-file must be included in the environment variable CLASSPATH or in the javas command-line option -cp.
Before we get into our example programs we need some database setup with table and sample data. Include db2 driver path in the CLASSPATH. Steps to include to db2 drivers in the class path.
