i have been searching the internet but I cannot find anything clue to this issue.Appreciate if anyone can help me with this.
Currently I have a form in my JSP. This form when submitted should return back to this JSP again.
I have beans to capture the fields for a particular form <jsp:useBean id="formHandler" scope="page" class="ed21.nday.bean.CapturingNomParticularsBean"> <jsp:setProperty name="formHandler" property="*"/></jsp:useBean>
However if I submit this form and return back to this JSP, the rest of the contents (outside this form) will be rewritten and will query my database again. How can I just retain the information in the JSP?
I can paste my codes if you do not understand what I say.

This is why the pattern that you are using is no longer considered apprpriate. By mixing your processing with the generation of the page, you have no ability to separate them.
You would be better served to study modern accepted practices with regards to web application structure. Perhaps this article might be a good starting point.

thanks for your reply.
However i think you might have misunderstand my questions.
I use a bean in my jsp and when I click submit, all the get and set methods in the bean will be invoked. How can I just specify which set methods to invoke?
I cannot use a variable/flag as once I click the submit button and return to this same page, all the variables are reset and all set methods are invoked as well. One of my set method is calling the database. I do not want this method to be called again since it has been called once. I want it to call once when the JSP is shown by a user.
