Re: Struggling with select/options
where 'temp_collection' is the type of class referenced by the 'name' attribute of the html:select, 'id' is the value returned by the getId() method (to be entered into the 'value' field of the option), and 'name' is the value returned by the getName() method (to be the text dispayed by the option). So, if your collection (added to the request object by the controller class) is of type com.whatever.TestClass objects, and TestClass has the methods getId() and getName(), the following jsp code would (should) produce the following html code: jsp code: [text label:] html code: [text label:] [name of first TestClass object] [ ... ] [name of last TestClass object] Hope this helps, - eric - Original Message - From: "Martin J.

Struggling with select/options
The examples I've seen using all seem to reference a collection defined in the same jsp as the options tag. Could someone provide a rookie with an example where the collection bean is not defined in the same jsp, but rather by, say an action servlet or an application bean? For example, say I've got a User bean with a Vector of ints called Accounts.

Jean-Noel, merci beaucoup. Although using the collection mode of options, rather than name made, I'm accomplishing what I wanted to do. thanks again > -Original Message- > From: Jean-Noël Ribette [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, February 27, 2001 7:43 AM > To: [EMAIL PROTECTED] > Subject: Re: Struggling with select/options > > > > Did you put an int in your collection ?

OK, just have a look at the subscription.jsp page in the example
application, and remove the line 'pageContext.setAttribute("serverTypes",
list);'
Then add the following lines in the method perform of the class
EditSubscriptionAction let's say before forwarding the control:
java.util.ArrayList list = new java.util.ArrayList();
list.add(new org.apache.struts.example.LabelValueBean("IMAP Protocol",
"imap"));
list.add(new org.apache.struts.example.LabelValueBean("POP3 Protocol",
"pop3"));
list.add(new org.apache.struts.example.LabelValueBean("Another Protocol",
"another"));
session.setAttribute("serverTypes", list);
This displays the protocol names and the option values are set to "imap"
"pop3" and "another".

Did you put an int in your collection ? Did you try with a Integer ?
