to tell your container to load a servlet on startup, use this block in
your web.xml file:
<servlet>
<servlet-name>SomeServlet</servlet-name>
<servlet-class>fully.qualified.package.SomeServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
in your startup servlet:
public void init() {
// do some parsing and build your array
//set your array in the servlet context
getServletContext().setAttribute("someKey", yourArray);
}
in any jsp within this application context:
<%
String[] yourArray = (String[])application.getAttribute("someKey");
//do something with yourArray
%>
hope this helps...
