RE: two users see the same session

Nikhil, I have seen this problem occur when using JSP and incorrectly defining session variables or beans in the declaration part of the script. e.g <%! BeanClass bean = new BeanClass(); %> Make sure only initialise session variables or bean classes in the context scope ie <% BeanClass bean =

RE: Form Double Submit Detection

Tom, Don't know if this is complimentary to your workflow, try a javascript confirm (ie a client side pop-up, asking the user to click "Ok" to continue). This will catch any double clicks on the client side. Hope this helps Bill -Original Message- From: Tom Parker [mailto:[EMAIL PROTECTE

RE: JSP seems to be executing twice and we are getting duplicate records in our database

Adrian, If you do not want anothe rows created every time the page is submitted, then you are going to have to implement something to stop this. TOMCAT will not do this for you. Without knowing the requirements for the form, stopping multiple rows being generated could be as simple as: - Assign a

Zafar, You need to test for the null after you have retrived the parameter from the query, via jdbc ResultSet.wasNull() Code might look like CallableStatement cs; // setup the callable statement stuff prior to here ResultSet rs = cs.executeQuery(); while (rs.next()) { String param = rs

RE: Share Java resources between two (or more) servlets

Andreas, Firstly, the servlet with db connections should be created and added to the ServletContext (hence not really a servlet). All other servlets can than access this object via getServletContext.getAttribute() etc. This servlet is defined as a servlet, loaded on initialisation. You must releas

RE: Form based security and "Remember Me"

A thought (just started following the thread). I can see a problem, in that the cookies may never get initialised because of the use of the checkbox. If the checkbox hasn't been selected, you'll always receive null from the form. Would suggest using a radio button instead, where the parameter wil

RE: How to enable secured JSP to be cached by browser?

Try request.getParameter() also you should test for null on the parameter (it will probably cause a NullPointerException down the line) HTH Bill -Original Message- From: Erik Price [mailto:[EMAIL PROTECTED]] Sent: Friday, 24 January 2003 9:16 AM To: Tomcat Users List Subject: strange res

RE: Form Data & IE vs NS

[Suggestion] Don't rely on browsers to retain the previous data on a a posted form. If you have detected an error, retrieve the data that was posted (via request.getParamter()) and populate the form yourself. Sample scriptlet could be <% String lastFoo = ""; //error detected, haveError set to tru
