Re: How do I pre-select an element from a select list?
Remove the value attribute from the html:select tag. In your action's
perform method, call formbean.setChoice("2") prior to forwarding the
request to your jsp.

This helps a lot... it was very clear. I'm stuck on one more thing. I need
to dynamically set the preselected value from the Action class. I tried
adding a property to the form:
.. I then set in the form for selectedCurrentLocation to be a string that
was one of the values of an option, checking the source to compare for sure.
It doesn't work The source shows that the parameter value="something" for
the select tag doesn't even show up. When I replace it with a hard-coded
value="2", for instance, it does work, however. If you or someone else
could help, it'd be very much appreciated. If more information is needed,
lemme know. Thanks.

Re: How do I pre-select an element from a select list?
Step 1.
In JSP
Step 2.
the formbean has methods getLabels and getValues()
public Collection getLabels()
{
ArrayList a = new ArrayList();
a.add("One");
a.add("Two");
a.add("Three");
return a;
}
public Collection getValues()
{
ArrayList a = new ArrayList();
a.add("1");
a.add("2");
a.add("3");
return a;
}
Step 3.
Notice the value attribute of .This is the value to compare
with for marking an option selected. Since I have specified value="2" so
option "Two" will be selected.
