I think i can help you.The example is :
import java.io.* ;
import java.sql.* ;
import javax.sql.*;
import oracle.jdbc.driver.*;
public class test extends HttpServlet
public void init(ServletConfig conf) throws ServletException
super.init(conf);
public void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
res.setContentType("text/html;charset=GB2312");
ServletOutputStream out=res.getOutputStream();
out.println("test");
try
Class.forName ("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection
("jdbc:oracle:oci8:@oraserver", "ycjx", "xjcy");
// ("jdbc:oracle:oci8:@qit-uq-cbiw_orcl", "scott", "tiger");
// or oci7 @TNSNames_Entry, userid, password
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select sj from dy_xstw");
rset.next();
out.println(rset.getString(1));
rset.close();
stmt.close();
conn.close();
catch (SQLException ex) {out.println("err1");}
catch (ClassNotFoundException ex) { out.println("err2");}
catch (java.lang.Exception ex) {out.println("err3"); }
}
