Iam trying to accept a username and password for the Oracle database and then put the resulting database connection into a session variable...
here is my useless code,,,please help....the only error iam getting is to do with the PrintWriter,,,

First iMac and I dont have a clue which one to buy :(

I have seen the light and now looking to buy a second hand Apple iMac 4,1. The specs are
Intel Core Duo 1.83GHz 2MB L2 Cache
2GB 667MHz RAM
160GB Hard Drive
17" screen.
Tiger10.4.11
My friend wants £200 for it which seems a good deal...but i dont know much about iMac's, as I have had windows based pcs for many years.
I do a lot of video editing and my widnows PC just cant cope at all, constant crashing and performace issues.
so my questions are
Is this sutible for HD/SD video editing and what software would you recommend ? Anyone have any slow down or performance problems ?
I will have to upgrade the HDD as 160gb is far to small, whats the largest HDD i could install and is it any more difficult to fit then a PC ?
Thanks
Donna

It isn't a bad deal but it probably isn't a good deal for you. I have its big brother (so to speak) in my guest bedroom for visitors to use while they are with us. I have upgraded it to Snow Leopard and have Photoshop Elements 8, as well as Office 2008, a few games, and other programs. Back when it was my main computer, about 3-4 years ago I even did some video editing in iMovie.
But as captfred said, Snow Leopard is as far as you can take it which means in about 18 months you are likely to see software coming out that it cannot use. Already it is too slow for the newer versions of video editing software (unless you intend to use iMovie). The drive is too small which isn't a deal killer - for the last year or so I was booting mine from a 500GB FireWire drive.
But I strongly urge you to look elsewhere. The good deal your friend is offering would make a very good second computer for the household. I don't think it begins to fit your needs. BTW - Apple's refurbished computers are generally top notch. They tend to be returns as opposed to used. They come with a full year warranty and are elligible for AppleCare extended warranty just like a brand new computer.

Itunes will not play my music, when it does it plays for about 10 seconds then speeds through the rest of the song then jumps through the nexts songs in the album, anyone got any ideas dont have a clue

Please Help me If you have an idea for a solution to this problem!

You need the admin password you created when you first set up the machine. Just about every installer running under OS X will require you to authorize the installation by entering an administrator password - even software update requires this. You really should not forget your admin password, as it is required for many things in OS X since, unlike Windows, you often need to manually type in the admin password to proceed with an install or update (whereas Windows will take admin authority, if you are logged in as an admin, by simply clicking continue or yes).
If you cannot remember your admin password, you can reset it from the recovery CD that came with your mac - http://support.apple.com/kb/HT1274

A few days ago with the new Itunes update, i forgot to restart my computer and now itunes will not open. I don't feel comforable uninstalling becuase i dont have all my music saved on an external hard drive. Any advice? Help please!

Every other answer is saying to uninstall then reinstall but i really dont feel safe doing that without all my songs externally saved (just incase) and now i cant even get into itunes!

What error message are you getting when you try to launch iTunes? (Precise text, please.)

i dont have any credit card.
what can i do for session itune?

There are instructions on this page for how to create a new iTunes account without giving credit card details : http://support.apple.com/kb/HT2534
If those instructions aren't used when creating an account then credit card details will need to be entered before the account can be used to download any item from the store.

Servlet Session Object

 I need to get the lastAccessTime of the servlet which I have deployed on Weblogic
 7.0.
 I have found that by using ServletSessionRuntimeMBean interface which has a method
 called getTimeLastAccessed, I can get the same.
 I am not able to get the same. Can any one sujject the way I have to go for this.


Hello Linus,
Actually, you would want to retrieve the necessary objects from your servlet context
and then pass them along to your session EJBs. It's not necessary to pass the
entire ServletContext object to your session bean. You should wrap the values
in DTOs (Data Transfer Objects / Value Objects) and pass them along to your session
beans. Also, it's not good to couple your EJBs with Servlets, as they may be eventually
accessed from standalone clients in the future. For more information on this design
pattern, please see the following link:
http://java.sun.com/blueprints/corej2eepatterns/Patterns/TransferObject.html
Best regards,

IllegalStateException: Internal Servlet Session Process Error Found!

 I keep getting the annoying error as listed, and the server also keeps reporting
 that I can only connect from 0 unique ip addresses. Has anybody else seen these
 type of frustrations on 8.1 sp2, or can explain them.
 With as much detail omitted for simplicity;
 Frustration 1.
 I have a 8sp2 server running all ok, occasionally after a redeploy of an ear file
 I attempt to load a jsp file, and the error below is thrown.
 The JSP has a bean which is session based, and as from following the stack trace
 it is around some weblogic code which tests if my license allows access to the
 http session (on a developer license). I then have to start another server instance
 and do a deployment of a v.simple war, and access this, then deploy the same war
 to the broken server and access that, then the initial jsp works fine. no code
 changes just environment stops, starts and redeploys!
 Frustration 2
 Server runs ok, tray and connect from two machines (I have an ldap server that
 wants to 'broadcast' messages to my server), error of too many connections.
 The ip connection issues can in most cases be removed with a server restart.

How to share objects between two ADF Faces servlet sessions

I gather the application scope is one way to go for sharing data between sessions in an ADF application. Are there other more generic methods of sharing data between servlet sessions?
For example, let's say we have a JDev 101.3 ADFBC/JSF app. (or JDev 11g for that matter). In this app we also register a servlet in web.xml. So two people log into this application and access this defined servlet, creating two instances of that servlet...I guess. Is there a way for those two instances/sessions to talk to each other? Pass data back and forth? Should I read about JMS? Or does application scope sound better? I guess a direct communication would be more tidy, than putting data on an application bulletin board, lilke application scope.
Any thoughts?

Hi,
Only one instance of each servlet defined in web.xml gets created, not one per user. You're right about the sessions though, one per user is created. You're right on the other parts as well I think you could use application scope to do something like that, or the data base for that matter, depending on the use case.

Looks like the managed server is making a request of the admin server
and propagating the "guest" principal instead of "system".
These principal propagation errors from managed-to-admin seem to
happen all over the place with different MBeans, and get patched one
place at a time in various BEA service packs. For instance, there's
another issue with accessing the XML Entity Cache from a managed
server, and I'm sure I've read about others. Isn't there a way to
make sure these errors no longer occur with any MBean requests from
the managed server?

Add
acl.access.weblogic.admin.mbean.MBeanHome=guest
in the filerealm.properties file.

Get the Web users Clipboard text in Servlet session

We have a small web application � uses JSPs , Servlets and runs on Tomcat Server.
We are trying to get the end web user�s ( browsers ) Clipboards copied text in our Servlets session.
We know there is some AWT API to get the Clipboards copied data.
java.awt.datatransfer.Clipboard clipboard = java.awt.Toolkit.getDefaultToolkit().getSystemClipboard();
// Get data from clipboard
java.awt.datatransfer.Transferable clipData = clipboard.getContents(clipboard);
But if we use this piece of code in our servlet session, we always get the Clipboard text, which is copied on the Server. Not at the users / browsers.
So, we wonder are there any ways or similar to get the Users clipboard text in that users session.
Any help would be great.

Its the same old story.
Java code is only running on the server.
At the client end all you can work with is HTML and javascript.
With Internet explorer you can access clipboard data:
http://msdn.microsoft.com/workshop/author/dhtml/reference/objects/clipboarddata.asp?frame=true
Grab it with javascript, put it into a hidden field, and submit the page.
That will pass it as a request parameter to your jsp/servlet, and you can get at it that way.

Apparently I have MULTIPLE Apple ID's, many linked to very old computers/emails that I no longer use and I have no clue what they are nor what the passwords could possibly be. I just want to be able to listen to music THAT I OWN!

I am trying to play music on my iTunes that I had burned from either CD's that I had bought & own (in order to preserve the CD from damage and it is all only for my personal use) or purchased through iTunes. Much, but not all of this was done on an old computer, and on old e-mails that no longer exist, and for that matter I have no clue what the passwords could possibly be! The computer that I use now is at least 10 years old, so how am I supposed to remember passwords from that long ago? I am constantly being told to reset my password, but that apparently just seems to compound the issue. One account will not even accept my birthday and my security question which I know with 100% certainty are correct. I JUST WANT ACCESS TO MUSIC I OWN OR HAVE PURCHASED over the past 20+ years, and I don't care what computer I did it on or what e-mail address I used, and forget about trying to recall my password! Apple makes it so difficult to do passwords it's ridiculous! I would need a book to write down every password that I have tried, and apparently not succeeded in using! add to my frustration is that my son put literally TONS of his music onto my computer and used his various Apple ID's and passwords, and it's just a bumble cluck of a mess. AGAIN, I only want access to MY MUSIC!

You're supposed to remember them or make note of them because they are key to a resource in which you have invested financially, just like keeping records for bank accounts you have or keys to your car. It is just that people haven't woken up to the importance of having a digital legacy too.
Here are resources for forgotten passwords:
