Now, im assuming that it has something to do with the name of the bean, althoguh i cant see how thiswould effect it, yet im here asking for help on the subject never the less. Here is the top lines of code from my bean:
import java.sql.*;
public class loginBean {Also in my jsp where i am calling my bean:
<jsp:useBean id="loginBean" class="loginBean" scope="session">
     <jsp:setProperty name = "loginBean" property = "userName" value = '<%=request.getParameter("user")%>' />
     <jsp:setproperty name = "loginBean" property = "pass" value = '<%=request.getParameter("pass")%>' />
</jsp:useBean>Im stuck and i dont like being stuck, any help will be appreciated, thanks.

The Bean class must BE PART of a pckage otherwise it never works in Tomcat
package abc;
public class logingBean{
<jsp:useBean id="loginBean" class="abc.loginBean" scope="session">     <jsp:setProperty name = "loginBean" property = "userName" value = '<%=request.getParameter("user")%>' />     <jsp:setproperty name = "loginBean" property = "pass" value = '<%=request.getParameter("pass")%>' /></jsp:useBean>
