PLEASE HELP at Java Servlet / Java Server Pages !!!!!

[nowy84]

// Forgive my English
I have to write a program (JS or JSP), which connect with Oracle and
get out date from some table. I've found some example, but it makes
errors (
I installed these :
J2EE 5.0
Tomcat 5.5.17
Oracle Express Edition 10.2g

I put ojdbc14.jar in in folder, where is my .jsp file.
Source of .jsp :
<%
Class.forName("oracle.jdbc.driver.OracleDriver");
java.sql.Connection
connection=java.sql.DriverManager.getConnection("jdbc:
oracle:thin//localhost:3306/"baza","login","haslo");
java.sql.ResultSet rs=connection.createStatement().executeQuery("select
* from
$TableName");
out.println("col count is "+rs.getMetaData().getColumnCount());
String colName=rs.getMetaData().getColumnLabel(1);
out.println("col label is "+colName);
while(rs.next()){
Object o=rs.getObject(colName);
out.println(colName+" "+o);
}

I'm not sure that your code is suitable for a JSP. It looks more like
the code you would use for a servlet. There are some Exceptions that
need to be handled as well (ClassNotFound, SQLException).

You should also put your ojdbc14.jar in your applications WEB-INF\lib
folder in tomcat.

If you want to run the statements, you might read up on JSTL tags,
specifically <sql:transaction>. Otherwise, your code is on its way to
working as a servlet so you could always try the servlet first to make
sure your DB connection and drivers are good. Here is the code I ran
on my Tomcat install and it worked though you will want to work on the
formatted output because it doesn't appear to be what you are after.

//be sure to change the connect string

import java.io.PrintWriter;

private static final String CONTENT_TYPE = "text/html;

HttpServletResponse response) throws
ServletException, IOException {response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();

connection=java.sql.DriverManager.getConnection("jdbcracle:thin:<username>/<pass>@<host>:<port>:xe");

rs = connection.createStatement().executeQuery("select * from

out.println("col count is "+rs.getMetaData().getColumnCount() +
"<br>");
String colName = rs.getMetaData().getColumnLabel(1);
out.println("col label is "+colName);
while(rs.next()){
Object o=rs.getObject(colName);
out.println(colName+" "+o);
