Hi all,
once again thank you for your comments about exception handling. I have now
revised by strategy.
One thing I would like to share with you is:
I had a simple servlet that accepts a parameter from a requesting page, it
then adds the parameter to a Result Bean, the bean is then added to the
session object. A JSP page was then called. The JSP page then displayed
the results by accessing the Result bean and extracting the parameter value.
It worked. Now I had 3 web browsers loaded on my machine and added
different values to each text box (one per web page). I then executed the 3
Web Pages at the same time. Well! the results were different! Sometimes all
pages showed the same result and sometimes 2 would etc... It took me a
while to understand what had happened; I add declared by Result bean at the
class level - outside of a method. I believe that you should not declare
objects that will have dynamic data outside of the method that is using
them. I removed the declaration from the class level and declared the
Result Bean in the doGet method where it is used. Now I can have as many
web browser executing at the same time and all displaying the correct
information.
Am I correct in my assumptions - it seems very fundamental.
Best Regards
Marc
