Hi
Scenario :
1. User submits form in JSP1 which Action1 saves to database. 2. Action1 set Form1 into session. 3. Action1 forwards to JSP1 again, which is suppose to display newly added form with other forms previously added.
How do I make JSP1 to get values from database BEFORE JSP1 displays and set them into session? I suppose I have to do this in Action1 but for the first submission of form1, Action1 is not called yet by JSP1.
From my analysis, there will be situation where there will be multipleinput sources into a particular JSP. That means I need to have my
'update from database and set in session' codes in all the Action
classes that forwards to JSP1?
In another words, how do I call the update method in Action1 from Action2 before forwarding to the JSP which display my updated data.
This is duplication of codes and inefficient to me. There must be a better way to do this in Struts.
My question might be confusing..I am trying my best. Tell me if its unclear.
It's unclear:)
Some of you terminology might just be wrong which is making it more confusing. For example in step 2 above, are you setting the form in session scope yourself? You normally don't need, or want, to manually do this. You delcare the scope of your form in your action mapping.
I think what you are wondering about is "How do you get your form populate for your JSP so that that user can alter it?" (I could be wrong here)... anyway I like to use a DispatchAction which has several methods in it... setUp, Update, etc. So your first call when the user clicks on a link would call the setUp method and there you would make sure your form is populated with the data it needs and you forward to your JSP. As a side note, you do not need to be using Session scope for this. Do you have a particular reason why you need to be using Session scope for your form (many times you do, but I'm guessing in this case you don't and you are using the Session because you are not understanding the flow of how Struts operates).
