if I understand correctly what you'd like to achieve, one way to do it would
be to use the Templates or Tiles tag library:
- you setup one template: /CarMenu.jsp with the reusable HTML code :
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>
<html>
<body>
<table>...</table>
<!-- this would insert some text using the Templates taglib -->
<template:get name="someText" />
</body>
</html>
- you use one jsp page for selectRentalCar aka /SelectRentalCar.jsp which
simply uses the CarMenu template and provide it with the appropriate message
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>
<template:insert template="/CarMenu.jsp">
<template:put name="someText">selectRentalCar text</template:put>
</template:insert>
- and you use another jsp page for addRentalCar (/AddRentalCar.jsp) which
also uses the CarMenu template
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>
<template:insert template="/CarMenu.jsp">
<template:put name="someText">addRentalCar text</template:put>
</template:insert>
it's good practice to store your templates under the WEB-INF/ path to
prevent direct access from browser requests (internal access from Servlets
or JSPs will still work, though).
