I am using WSAD5.0,Oracle9i
I have added the classes12 Jar file in WSAD in the following locations.
1)Window-->Preferences-->Classpath Variables-->CLASSPATH=C:/oracle/ora9i/jdbc/lib/classes12.zip
2)pROJECT-->pROPERTIES-->
Java Build Path-->Libraries-->addJars
Is that ok?
After that i have created a class and a
servlet,the code is running fine in class but in servlet its giving an exception.Here is the class file code and result
import java.sql.*;
import oracle.jdbc.driver.*;
class JDBCVersion
{
public static void main (
String args[])
throws SQLException
{
// Load the Oracle
JDBC driver
DriverManager.registerDriver
(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection
("jdbc
racle:thin:@localhost:1521:esr","scott","tiger");
// Create Oracle DatabaseMetaData object
DatabaseMetaData meta = conn.getMetaData();
// gets driver info:
System.out.println("JDBC driver version is " + meta.getDriverVersion());
Statement smt=conn.createStatement();
ResultSet r = smt.executeQuery("SELECT * FROM emp");
while(r.next())
{
int j=r.getInt("empno");
String s = r.getString("ename");
String d = r.getString("job");
System.out.println("Employee Details = " + " " +s+ " " + j+ " " +d);
}
}
}
JDBC driver version is 9.2.0.1.0
Employee Details = SMITH 7369 CLERK
Employee Details = ALLEN 7499 SALESMAN
Employee Details = WARD 7521 SALESMAN
Employee Details = JONES 7566 MANAGER
Here is Servlet Code and result:
import java.util.*;
import javax.servlet.*;
import java.sql.*;
import javax.servlet.http.*;
import oracle.jdbc.driver.*;
//import oracle.jdbc.driver.*;
class MyConnection extends HttpServlet{
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
try{
DriverManager.registerDriver
(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection
("jdbc
racle:thin:@localhost:1521:esr","scott","tiger");
DatabaseMetaData meta = conn.getMetaData();
System.out.println("JDBC driver version is " + meta.getDriverVersion());
Statement smt=conn.createStatement();
ResultSet r = smt.executeQuery("SELECT * FROM emp");
while(r.next())
{
int j=r.getInt("empno");
String s = r.getString("ename");
System.out.println("Employee Details = " + " " +s+ " " + j);
}
}
catch(Exception e){
System.out.println("exception");
}
}
}
