Hi :-) first, the most important, we must make the following clear:
:-)
- if I have n ideas, can I have n beers? if(not), return; :-)
- if my ideas are all not right, but because they are more than one,
and I type a lot of words with keyboard, so can I also have 1 beer?
if(not), return; :-)
I am not sure, I have some suggestions:
* use
- ServletContext.getAttribute(...)/setAttribute(...)
and
- RequestDispatcher/sendRedirect
to pass the XML data from MyServlet0 to MyServlet1
* use
- HttpSession.getAttribute(...)/setAttribute(...)
and
- RequestDispatcher/sendRedirect
to pass the XML data from MyServlet0 to MyServlet1
* use
- (Http)ServletRequest.getAttribute(...)/setAttribute(...)
and
- RequestDispatcher/sendRedirect
to pass the XML data from MyServlet0 to MyServlet1
* use
- MyHelper which is loaded by Shared classloader to save data
and
- RequestDispatcher/sendRedirect
to pass the XML data from MyServlet0 to MyServlet1
* and from several emails, perhaps it is better to make the object which
"wrap" the XML
data Serializable.
* another "non-OO" way is : if it is possible to "put" the XML
data in a String which is not very long, we also can use:
RequestDispatcher
rd=request.getRequestDispatcher("/servlet/MyServlet1?tailPxml=...");
rd.forward(request, response);
my most favorate bear brand is ... //hahahahaha :-)
