InitialContext ctx = new InitialContext(); DatabaseMetaData dm = null;

DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/mysqlDB"); Connection conn = null;

Statement stmt = null; try {

conn = ds.getConnection(); dm =conn.getMetaData(); out.println("Connected to-> database version" +dm.getDatabaseProductVersion());

}catch (Exception sqlex) { out.println(sqlex.getMessage()); }finally{

conn.close();

}
