Servlet Response Send Redirect 2 Answer(s) 3 years ago
Posted in : JSP-Servlet
Hi,
Thank you for your previous answer, the code works great. Sorry to bother you guys and perhaps this would be one of my last questions as I am almost finish with my web medical clinic app. Please if you guys can answer the following related to my last post regarding editing records.
1. In the code that you have given last time, I want to be able to do search on the Mysql table based on more than one column instead of one. what i mean is lets say user does a search on patient data based upon their id or last name. The result gets populated in the search table, user clicks a particular record but since this table has a patient who's visited many times, the id although FK is repeated and so the distinguishing element is the date of visit from the visit table. Can you please show me how I can pass more than one column value to the next jsp?
2. I have a servlet that saves patient data from a form into mysql table.I have some form validations through some javascript, but when the user clicks save or submit, there might be some Mysql errors that arise, I've catered to them by using JOptionPaneShowMessageDialogue in my servlet followed by a response.sendRedirect("index.jsp). the problem is that when a user has filled out a long form and gets a mysql error, I want instead of the response.sendRedirect is there some other method that the user doesn't loose the fields he already has filled because right now when I receive lets say a duplicate primary key(i have kept a non-auto increment), the user clicks ok on the message dialogue box and then index.jsp gets refreshed with all existing fields gone. Can you tell me a better way to do this?
Please tell me whether index.jsp is the search page where we are displaying the search table.Also post the servlet code that saves the patient data.
