Hi,
In one page of my application i am trying to iterate through one
collection
for populating one combo box. But it is showing
javax.servlet.jsp.JspException: Cannot create iterator for this
collection
I have one LoginForm that extends Validator form and it containg one
object
of User. This user object contains a List of user roles .Actually i am
trying to display these user roles in my combo box in the jsp page. My
code
is below.
I am using struts 1.3 for develping this project ...
Please help me
My form class is below...
public class Loginform extends ValidatorForm{
public String userName;
public String passWord;
public User user = new User();
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassWord() {
return passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
/**
* Reset all properties to their default values.
*
* @param mapping The mapping used to select this instance
* @param request The servlet request we are processing
*/
public void reset(ActionMapping mapping, HttpServletRequest request) {
super.reset(mapping, request);
userName = ;
passWord= ;
}
}
User object is
public class User implements Serializable{
public String userid = Ashli;
public String userName = Ashli Isaac;
public String passWord = 123456;
public String userNumber = 1001;
public ListString userRoles = new ArrayListString();
public String loginStatus;
public String riskCounter;
public User(){
userRoles.add(Admin User);
userRoles.add(Trial User);
userRoles.add(BackUP User);
userRoles.add(Super User);
}
public ListString getUserRoles() {
return userRoles;
}
public void setUserRoles(ListString userRoles) {
this.userRoles = userRoles;
}
the code snippet for iteration in jsp is
tr
td width=30%
logic:iterate id=results
name=loginForm property=user
bean:define id=result
name=results property=userRoles
bean:write
name=result/
/bean:define
/logic:iterate

RE: Logic Iterate problem
Did you have the tld declaration at the top of your jsp page e.g
%@ taglib uri=/WEB-INF/struts-logic.tld prefix=logic %
?
