Hi there! I'm realllyyyy getting confused..
I'm trying to create a table with the resultSet from a mysql database (I
tried DataView but gave up..too much for me) by using a ListView. The
problem is that I keep getting an ClassCastException: java.lang.String.
Wicket tells me this happens in the populateItem() method when I try to cast
the ListItem to User (of course..). I have a simple User class with getters
to retrieve: int userid, String name, String phone, etc...I don't know why
this is happening so..could someone please help?
Thanks in advance,
Edd
[CODE]
....
/* create connection do mysql db and retrive a ResultSet */
NewConnection myconn = new NewConnection();
final ResultSet userTableData = myconn.queryTable("SELECT * FROM
user");
/* calling method that transforms my ResultSet (usersList) to a List
*/
List usersList = getUsers(userTableData);
ListView listView = new ListView("pageable", usersList)
{
protected void populateItem(ListItem listItem)
{
User user = (User)listItem.getModelObject(); //
CLASSCASTEXCEPTION HEREEE
listItem.add(new Label("userid",
Integer.toString(user.getUserId())));
listItem.add(new Label("name", user.getName()));
listItem.add(new Label("phone", user.getPhone()));
listItem.add(new Label("email", user.getEmail()));
listItem.add(new Label("type", user.getType()));
}
};
add(listView);
.....
/* method to convert ResultSet to List */
public List getUsers(ResultSet rs) {
List retval = new ArrayList();
try {
while(rs.next()) {
retval.add(rs.getString(1));
}
} catch (SQLException ex) {
ex.printStackTrace();
}
return retval;
}
