How do I save information from my applets?

I have an inventory applet. But I want to save the information I input to the applet. Everytime I close it, I lose all those information. How do I do this? Do I do it with streams? If so, could you show me the ropes or send me a website. Thanks to anyone who can help! =)

well well well dekassegui!!! what u said could save my ass from my manager.. coz he will kick me out if i didn't do that for him,.. i've been through alot of documentation regarding applets and their resterictions.. i know that for an applet to access the memory (File IO or Database access) it needs a permission file on the same folder as the applet... some documentation says that an applet should be signed before doing so!! and plz don't ask me what a signed applet means : ) well if that would help plz give me the guide for that.. thanks in advance

  • How do I save photos from email to the photo library?

    How do I save photos from email to the photo library? I've seen an online demo of users that hold their finger or thumb over the image for a few seconds and a "save photo" window option appears. That doesn't work on my 6-month old iphone. It's version 1.1.4 (4a102) ???? Help! Anybody with an answer?

    Never mind. I figured out the 2.0 update. My system wasn't updating I-tunes...and the I-phone update option window was hidden behind some other system information. I figured it out. The download, install and re-synch took about an hour. Lots of horror stories out there about people trying to activate their new I-phones. Glad this worked for me!

  • How can I transfer information from one ipad to another?

    how can I transfer information from one ipad to another ?

    What kind of information? You can sync things like Contacts and Calendars by using iCloud. You can backup one iPad to iTunes on a computer and then sync the backup to the other iPad. You can configure your iTunes content and sync the same content to both iPads.
    It is based on what you want to do. Or are you looking for a way to send files from one iPad to another wirelessly? There are apps to do things like that, as well as cloud services, such as DropBox.

    Hi,
    I am using WLS default authentication to protect my JSP pages. Can someone tell
    me if it is possible to add more fields to the default login box (in addition
    to login and password boxes, I want to ask user the department name). In additional,
    can WLS propogate this information (department name) along with other security
    credentails to other J2EE components such as EJBs? In my EJBs I want to be able
    to get the department name that user provided during login and then use that for
    conditional business logic.
    Any insights on this subject will be greatly appreciated.
    TIA,
    -NealYou can't do this with the default simple authentication. That can only handle a
    username / password combination.
    You should be able to do this with JAAS. You could write a LoginModule that
    populates the department as a Principal or public Credential on the Subject in
    addition to the normal authentication. You would have to do a callback handler
    that passed through the department info to it.
    This link has more on WLS's stab at JAAS:
    http://e-docs.bea.com/wls/docs61/security/prog.html#1039659
    Once you have associated the Subject with the access control context by invoking
    a doAs() you should be able to get it back at any point with
    Subject.getSubject(AccessController.getContext()) to get access to the
    department info.
    It will all be a bit of a chore, mind.

    If you have Lion and wireless you can use Airdrop to copy files back and forth. (You don't need an internet connection, just two reasonably recent Lion machines with WiFi cards.)

    How can I save photos from messenger

    I'm sorry, but are you referring to another app other than the native Messages App? I'm thinking that is what you are referring to, since I'm not aware of any setting like that in the native Messages app. If that is the case, it could be that you do not have Messages set to access the Camera Roll in Privacy. The app may not have access to the Camera Roll. Check that in Settings>Privacy and see if the Messages app is listed there. I'm guessing that you are referring to Facebook Messenger?

  • How do I save pages from my website in PDF, and prove the image was capture on a given date?

    How do I save pages from my website, [link removed] into a PDF file, with proof of the date the pdf file was created on? I need to display the content of each unique url of my site in PDF format for compliance purposes, and prove the image was taken from a given date. Anyone can help that would be great.

    Impossible to do with Reader. If you own Acrobat and use Create PDF from Webpage. The document will have a creation date. If you then sign the pdf on the date of creation, you have proof of when the document was created and proof that the document wasn’t altered since signed.
