Can't connect Tomcat 6 and oracle 10g XE for jsp database connectivity
Question
I am using Eclispe ganymede,tomcat6 and oracle 10g XE. I have connected all of them.Everything is working fine.
But I have created a jsp file which creates a table in database that is not working. There is no error. But when I check into database there is no table created.
My coding:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

Connection con=null;
try
{
Class.forName("oracle.jdbc.driver.OracleDriver");
con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE","system","123");
Statement stmt=con.createStatement();
stmt.executeUpdate("create table Black ( "
+ " id INT PRIMARY KEY, firstName VARCHAR(20), lastName VARCHAR(20), "
+ " title VARCHAR(20), salary INT " + ")");
out.println("Table Created");
}
catch(ClassNotFoundException e)
{
out.println(e.getMessage());
}
catch(NamingException e)
{
out.println(e.getMessage());
}
finally
{
try
{
if(con!=null)
con.close();
}
catch(SQLException e)
{
}
}
%>
</body>
</html>
This is what error says:

What is the output, is there a stacktrace? Have you defined the datasource as testdb?
You shouldnt anyway be doing sql-statements from a JSP page, put the sql-statements behind a DAO or use Hibernate or similar ORM tool.
Here is thehttp://www.oracle.com/technetwork/database/features/jdbc/index-091264.html download page for Oracles JDBC drivers. Take the matching one for your database, and the matching version of your Java vm. And put it under your tomcats lib/ directory.

Any exceptions raised?. Don't use JDBC connection code in Jsp.Instead keep in a DAO class.
Or Jsp tab libraries can be used.
Check this link to solve the issue.

You need to include the ojdbc14.jar file in your Deployment Assembly in your project. Using eclipse:
proj --> properties --> Deployment Assembly --> Add --> Add your jar file.

I want to add that in my project I had to change from:
String driverName = "oracle.jdbc.driver.OracleDriver";
to
String driverName = "oracle.jdbc.OracleDriver";
I am using Oracle Database 11g Release 2.
