Strange behaviour: "undefined method" error

Question

Hello!
I am trying to build a simple webpage.
I created a class UserData with some functions, two of them are getUsername and getLastname. I created a HTML form, with the fields username and lastname (written exactly like this), a JSP (signup2.jsp) with the following code:
<jsp:useBean id="user" class="phil.UserData" scope="session"/>
<jsp:setProperty name="user" property="*"/>
<jsp:forward page="signup3.jsp"/>and another JSP (signup3.jsp) with the following code:
<jsp:useBean id="user" class="phil.UserData" scope="session"/>
Lastname:
<%=user.getLastname()%>Ok. My problem is: when i submit the form, the signup3.jsp raise me a strange error:
"The method getLastname() is undefined for the type UserData". If I replace <%=user.getLastname()%> with <%=user.getUsername()%> ... well... it works!! It shows me the username I submitted.
So basically, my script "sees" a function within a class, but it raises an error when trying to call another function in the same class.
The listing of this "famous" class is:
package phil;
public class UserData {
    public String username;
    public String firstname;
    public void setUsername(String value){
         username = value;
    public void setFirstname(String value){
         firstname = value;
    public String getUsername() {
         return username;
    public String getFirstname() {
         return firstname;
}Anyone has any idea what this error is? I was clear enough? I don't even know how to explain it better....
I am using Windows XP, Apache with Tomcat 5.5.0, JRE 1.5.0u4 and JDK J2SE 1.5.0u4
Thanks!

"The method getLastname() is undefined for the type UserData"
If I replace <%=user.getLastname()%> with <%=user.getUsername()%> it worksOk, In your class I can see methods
public String getUsername() {
public String getFirstname() { I don't see any method
public String getLastname() { Add that method to your UserData class and try again.
