Hi All,
Here is a problem we are facing:
There are 2 two webpages JSP1 AND JSP2. These pages need some( lets make
it
more than 10..for the sake for discussion ) values as input for
generating
themselves. Now the user has a choice to navigate to JSP3 from either of
these pages. Now, once the user is done with JSP3 , he needs to be
automaticaly taken to the previous page he navigated from(JSP1 or JSP2).
Now, for this to take place, the JSP3 should have the knowledge of its
previous page and also take the responsibilty to pass the required input
values for generating its previous page.
Now, the question is what is the best way for this kind of data to be
passed between these pages. Currently, this problem is solved by using
Session
variables. But, this is becoming a maintenance nightmare, since session
variables are being thrown all over the place.
Are there any patterns or ideas to handle such situations in a more
elegant
way!!!

check the string for single quote characters, if you find one, insert
another single quote beside it so it will not generate an error.
e.g. input = O'Reilly
output = O''Reilly
Try using the String.replace() method.
