Jsp Parameters [Urgent!]
Hi everybody! Please I need help,... This is not a Tomcat question, but I know here I can find some JSP experts: Could you tell me all the ways I could send (safe) parameters from a jsp to a jsp file? Please discard the url parameters and the Session object... I have a jsp (Valida.jsp) which opens a new navigator window (javascript), and that new navigator window contents another jsp (Portal.jsp). I need to send some parameters from Valida.jsp to Portal.jsp. In fact the second Jsp is formed by frames and one of the frames has a jsp (Left.jsp) that needs those parameters... Could you please help me? Give some hints or examples... I really need your help.. Or if you couldn't, please tell me where I can find that information Thank you very much..

Re: Jsp Parameters [Urgent!]
If you don't want to use the session object, then you could use javascript on the client side. The simpliest form is just to call a function residing in the left.jsp page. Name the window you open and the frame you target and then later when you navigate to the frame (window), use the name. You can make this fancier by creating a javascript message handler. The message handler and message gateway are different javascript objects you create. The message gateway object would reside in a page that doesn't get reloaded. Any other page that gets loaded can register its onw message handler with the message gateway. Using the message gateway/handlers abstracts the what you want to do to not knowing the implementation details of other frames. I have successfully used this concept in one of out application. Hope this helps. /Peter 1. Set the data on the server before the jsp files are downloaded.

Re: Jsp Parameters [Urgent!]
Thank you very much for your answers! But Gary : , Do you mean the URL parameters is the only way to pass parameters from a jsp (script code) to another jsp? This is because I need to pass the password and username as parameters... Is this safe? I really want to find the safest way to pass them.. And Peter : , I said I don't want to use the session object because I don't know if it is safe. Do I have to use it?, is it safe? Thank you again!

Re: Jsp Parameters [Urgent!]
When you say safe you mean: 1. safe from the client that uses the pages, in order not to adjust his rights, for example? or 2. safe from the people that might try to steal confidential data from the users of your site? 1. In the first case the session is the safest way (because the data is managed on the server, no client can directly touch it). 2. Use SSL. It's unsafe even if you make your own socket connections. They :) still might get it. Anyway, using the session you can choose to delete the data at any time (simply invalidating the session). The session's purpose is the use in pages like you described.

Re: Jsp Parameters [Urgent!]
Nancy-- The only way to pass data from Javascript (to my knowledge) is through a URL or post etc. Maybe variations exist such as using hidden fields on forms etc -- however, these all revolve around opening a HTML/JSP page with query / post data. If your data already exists in the Java world, then you can simply access the session data as pointed out by Paul in his previous post.
