You can do something like this:
public void doPost(HttpServletRequest request,
HttpServletResponse response) {
...
try {
action.perform(this, request, response);
}
catch (Throwable t) {
request.setAttribute("javax.servlet.jsp.jspException", t);
RequestDispatcher rd =
getServletContext().getRequestDispatcher("/error.jsp");
rd.forward(request, response);
}
}
If /error.jsp is a JSP page with <%@ page isErrorPage="true" %>, the JSP
container assigns the value of the "javax.servlet.jsp.jspException"
attribute to the implicit "exception" variable. Your JSP page can then
use this object the same way as if it's invoked due to an exception
in a JSP page.
