Error using beans and JSP

Hi!
I m new to JSP and beans and was just trying out the sample example from tutorials. But i got struck using beans and JSP..
1. Initially i wrote an html using button and textfields and on
clicking on that button should open a jsp page named
SaveName.jsp
2. I wrote a bean class named UserData and wrote all get and set methods required.
3. I then wrote a JSP named SaveName.jsp and coded something like this..
<jsp:useBean id="user" class="UserData" scope="session"/>
<jsp:setProperty name="user" property="*"/>
<html>
<body>
<A href="NextPage.jsp"> Continue </A>
</body>
</html>
4. The coding of NextPage.jsp is something like this..
<jsp:useBean id="user" class="UserData" scope="session"/>
-------including other html tags...
I initially kept my all files in c:\tomcat\webapps\examples\jsp
directory and also compiled my bean UserData.java file here...but i got the error message when i clicked on button and my SaveName.jsp couldnt be opened to store the data..
The error is as follows :
org.apache.jasper.JasperException: Unable to compile class for JSPC:\TOMCAT\bin\..\work\localhost\examples\jsp\SaveName_jsp.java:57: Class org.apache.jsp.UserData not found.
UserData user = null;
^
C:\TOMCAT\bin\..\work\localhost\examples\jsp\SaveName_jsp.java:60: Class org.apache.jsp.UserData not found.
user= (UserData)
^
C:\TOMCAT\bin\..\work\localhost\examples\jsp\SaveName_jsp.java:65: Class org.apache.jsp.UserData not found.
user = (UserData) java.beans.Beans.instantiate(this.getClass().getClassLoader(), "UserData");
^
3 errors
I also tried to keep my class files in
c:\tomcat\webapps\examples\web-inf\classes directory but the same error follows...
Can anyone help me to solve this problem....
Thanks in advance
