Display data from oracle to tomcat

I have jsp file parked under catalina_home\webapps\mydir\my.jsp:

<%@ page import="java.sql.*"%>
<%Class.forName("oracle.jdbc.driver.OracleDriver");%>
<html>
<body>
<h1>Welcome to Emma's page</h1>
</body>
<%
try{
Connection connection = DriverManager.getConnection("jdbcracle:thin:@database:1521:SID",
"user1", "password");
out.println("Test");
Statement statement = connection.createStatement();
ResultSet resultset = statement.executeQuery("SELECT * FROM tblCustomer");
while(resultset.next()){
out.println(resultset.getString("prod_desc"));
}
out.println("Test1");
}
catch(Exception e){
out.println("Test1");
out.println(e);
}
%>
<body>
<h1>Welcome to Emma's page</h1>
</body>
</html>

Previously, it worked fine, displaying the text and result from database until I changed something in server.xml and web.xml (web.xml under WEB-INF, not in conf folder). I cannot see anything from the database anymore, just text.

How is the correct configuration of server.xml in order for me to display the results?

Thanks in advance.

Emma
