Should the jsp be tied to a form for this case?
I do not make up a form.
I do this in the jsp.
<%
List availableSystemList =
UserSystemService.getInstance().getAvailableSystemList(request.getRemoteUser());
request.setAttribute("availableSystem", availableSystemList);
%>
<html:select property="availableSystem">
<html:optionsCollection property="system_href"/>
</html:select>
where system_href is one of the attributes of availableSystem.
I get the error message of
ERROR - Servlet.service() for servlet jsp threw exception
