I have a struts app in which I use an action (say action A) to pass a bean (Bean A) containing data from the Model as an attribute in the request scope to a View ( JSP A). JSP A contains a Form that initiates Action B ( simply a Submit button) and thus on to View B(JSP B) after some more interaction with the Model. What I would like to do is re-use Bean A in Action B, as it contains data pertinent to Action B, and I don't want to query the model again for the same data. How can I do this keeping the data bean A in the request scope? I know I can achieve this by placing Bean A in the session scope, but this will accumulate memory and cause potential synchronization problems accross multiple users.
The real life scenario is this- Action A is selecting Patient cases from a database corresponding to a date range, and displaying the Case list data (Bean A) in a table (JSP A) . The next task is to display all the pharmacy bills for the set of cases defined in Bean A and shown in JSP A. So I would like to pass Bean A to the next Action B, which would forward the caselist to a helper bean, which in turn would query the Model for all the drugs used for all the patients defined in Bean A. The end result is a list of pharmacy Bills (View B) which would print out as all the bills for patients in a date range defined by the selection started by Action A. Any help gratefully received.
