Kenia,
There are a few ways to do this and I think you might be interested in
directly manipulating one servlet from another.
For instance, if you're in servlet B, you could first call a method in
servlet A's object (this method would print out the record based on the
booking number) then you could print out the additional information that
B handles.
Use Java's language reflection (this requires you know what method
you're looking for in A):
Servlet serv = context.getServlet("THE_NAME_OF_SERVLET_A");
Method myMethod =
servlet.getClass().getMethod("THE_NAME_OF_SERVLET_As_METHOD",null);
myMethod.invoke(servlet,null);
These methods throw a few exceptions so you'll have to wrap this in a
try/catch block. (I believe 4 of them!)
(By the way, if Servlet A's method takes arguments, you specify those in
the argument list:
public Object invoke(Object obj, Object[] args)
In the case i showed you, it's null but you would probably need to pass
in the booking number....
That is from the JDK documentation.)
Check the servlet documentation on this as well - there may be other
methods you'd be interested in.
Hope that helps,
