Code to put on servlet to go back to page

I was wondering how/what code to put on a servlet so that the page before calling the servlet is shown. I have a page when I submit it, it calls my servlet then the servlet saves to a database based on the parameters of the request. When that is done, I want to automatically go back to that page, with all fields now blank.
Thank you

Yes. Thanks for your reply. Another question though. I tried both options and why is it when I use the response.sendRedirect() all I have to put is the actual page. When I forward using the RequestDispatcher, I have to include the folder where the page is stored.
/FolderOne
'--> somepage.jsp
Thats the hierachy.
Also the url mapping for my servlet is FolderOne/someservlet
BTW. I wrote mine like this on my servlet
this.getServletConfig().getServletContext().getRequestDispatcher("/FolderOne/somepage.jsp").forward(req, res);Why the difference?

tried on a different mac. The same problem exists.
If that is the case, its extremely unlikely you have a bad USB cable on the seagate, rather as I mentioned earlier a bad SATA bridge card.
If the Seagate 1TB USB external wont open on either Mac and youve verified same (try a diff. USB cable if you have one however this is nearly never the case),....then to get the data off that HD (unless it is dead which is also extremely unlikely),......then you would need to extract the HD from its case and insert same into either a HD dock or USB HD enclosure.
8 out of 10 seemingly dead inopperable 1-3+ year old external HD are perfectly fine, rather the cheap 50 cent SATA bridge card fries and dies (alas)
reply back if you need help in extracting same.

Calling servlet from a backing bean

hi guys i need to call a servlet from a backing bean in JSF. how do i do that ?
The scenario is i have to call servlet on a different machine from my backing bean . I also need to pass an object to the servlet .
This object contains data which must be manipulated and inserted in the database by the calling servlet.
I also want that after insertion in the db the control must be passed to the backing bean .
Is this all possible???
Please help

HT1296 How do you put all music on Ipod back onto a previously crashed computer in which the original music files were not able to be restored?

Hi, HOW DO YOU PUT ALL MUSIC FROM IPOD BACK ONTO A PREVIOUSLY CRASHED COMPUTER IN WHIHC ALL MUSIC FILES WERE UNABLE TO BE RESTORED.
My computer crashed a few months ago and my IT guys were not able to restore my music files.. at least I can't find them. When I log into Itunes, all of my music and play lists appear but when I click to play a song in Itunes on computer, it says the files can not be found. My Ipod obviously has all of my music but I'd like to add more (without deleting what I've got on there) and to copy back whats on my Ipod back to my computer. If I plug together and my computer sync then I will loose all music... needing detailed instructions please.

from what i understand, the procecess is similar on both mac and pc, so i'll try help you here. have you set your preferences to "automatically update all"?
Yes i have.
if this isn't working, maybe try moving one that you are certain is in the correct format, manually. import it from scratch to your itunes, and then copy it to the ipod.
If i click 'import files' the only files it comes up with are text file. Should it be doing this?' So the only files i can import are written documents :/
If i select 'add files' it dosnt add them to my libary at all.
I tryed what you said, i deleted my movies then loaded one into my libary which i no is in the right format but it still said that it is unable to put into my ipod.
Thanks for trying to help by the way :]

Passing value from Servlet to JSP back to Servlet

Hi all,
I have a jsp page where a user submits a search string into a text box. The jsp forwards to a servlet which calls some java classes and checks a database. The classes generate a string which contains some html. The servlet then forwards back to the jsp which displays the the string:
<c:out escapeXml="false" value="${requestScope.ampList}" />The user then performs another action on this outputted html which is a listbox and when the user clicks on the listbox the onchange method submits the form. The JSP forwards the listbox value and I would like it to forward the "ampList" as well but I cant figure out how to do this.
Using a hidden input does not work because the string contains HTML. Does anyone have any ideas. I can just keep the search string stored a hidden input box but I would prefer not to regenerate the "ampList" as it means accessing the database again which will cause performance issues.
Thanks for any input in advance,
Tom

Ha,
Writing that message gave me an idea which worked:
<input type="hidden" name="ampList" value="<c:out escapeXml="true" value="${requestScope.ampList}" />" />

I have been rying to put OS X 10.4 back on my computer and Mavericks blocks it out ! Why can't put the operating system of my choice on the Mac Pro.

I have been trying to put either Tiger or Lion back on my MacBook Pro and it is blocked by Mavericks. Mavericks is a terrible operating system.

How to revert OS X back from Mavericks - https://discussions.apple.com/docs/DOC-6161
Some files such as iTunes may have been opened by newer versions under Mavericks and cannot be opened again by earlier versions that Tiger will require.
