URGENT PROBLEM: Please help me if you can :(
i am developing a symptom sorter function in JSP and MySQL, where the flow of data is:
Select pain type e.g Ear
Select category e.g. Hearing Problems
Checkbox selections
fever
cough
tired
sick
A combination of these checkbox selections should take you to the appropriate result. e.g tick fever, sick and tired, then the symptoms should be displayed. NB You must have selected the pain type and category already.
HJowever if u tick cough with the paintype and category selected then a messasge saying no symptom found should be displayed.
My problem is the correct implementation method to use!
The data is already stored in a database, with every possible outcome already worked out!
I need to know
1. Is it better if i put the data read from the db into an object and then put that object into a session? Where the jsp then gets the object and displays the results on a new page!
If yes how do i do this?
2. Is there another method of completing my task.
Thanks again!
The best way to accomplish this kind of view of the database is to follow the MVC Architecture. Just follow the following steps to display the appropriate view.
1)send the detailes checked/selected from the jsp to the ControllerServlet (Form action to be routed to ControllerServlet).
2)Write a Bean which takes the request object into the constructor and instantiate the same in ControllerServlet.
3)In the Bean get all the parameters from the request using req.getParameter("PainTypr")...etc.
4) check for the appropriate conditions based on the parameters obtained with existing database. and have a method in the bean to give the url back to the servlet. -- end of processing in Bean.
5) Back to the ControllerServlet redirect the request to the "url" as obtained from the Bean using response.sendRedirect(url);
6) if required write a Custom Tag to display the data in the desired format. which will be embeded in to the jsp that is displayed.
Just go through any MVC prototype for a clear understanding.
All the best
adios
praveen.

Got a problem with my Chatting-Room program, please help me if you can.
There is one bug in the code (should be just one), but I couldn't find it, I even recoded the whole thing, after I recoded the code, the same problem seems still there. I just can't find where the problem is. So I hope someone here can help me, thank you very much.
First, I made a Server and a Client. Server has 5 classes, and Client has 2 classes. My intention is that all the clients(running on other computers) will connect to the server (which is my laptop), and then they can communicate with each other. For example, if person A typed "Hello", person B and person C's computers will receive this message and display it.
The problem is that several clients can connect to the server (My laptop), but if one person type something, other people won't receive the message, it's blank on their screens. Maybe there is a problem when server receiving the message. So this is the problem I want to solve.
I have the code down there, here is a brife description what each class mainly does.
First class of Server is for connecting client, this class is named Server. Everytime a client is connected, the Server class calls the second class to store the client's information (which is its IP address), the second class is named People.
Third class is named Receiver, it is for receiving the massage from any one of the clients, then stores the message to a static field variable in Fourth class, fourth class is named Saying.
Fifth class of Server is named Sender, it is for sending the massage to the client, that message is the one that stored in Saying.
The First class of client is named Client, it prints any message that the server send to it.
The Second class of client is named SendFromClient, it wait for user to type something, and then send the message to the server, so server's Receiver class hopefully will get it and store it to the field variable in the Saying class.
Here is all the codes:
Server Class:

<taglib>
<taglib-uri>/tags/struts-html</taglib-uri>
<taglib-location>/WEB-INF/struts-html.tld</taglib-location>
</taglib>Now I am getting an error like ......."File "/WEB-INF/struts-html.tld"not found.
Hi Ashish

hello sir
my system needs itunes64 file i don't know from where i should get this file cuz my iphone 4 is all the time synced with this computer all the back up are in this computer i dont want to lose it coz i did restore once so i dont have all the data in my phone i have it in itunes please help me with itunes 64
thank youBack up all data to at least two different storage devices, if you haven't already done so. One backup is not enough to be safe. The backups can be made with Time Machine or with a mirroring tool such as "Carbon Copy Cloner." Preferably both.
Boot into Recovery mode, launch Disk Utility, and erase the startup volume with the default options. This operation will destroy all data on the volume, so you had be better be sure of your backups. Quit Disk Utility and install OS X. When you reboot, you'll be prompted to go through the initial setup process. That’s when you transfer the data from one of your backups.
Transfer only "Users" and "Settings" – not "Applications" or "Other files." Don't transfer the Guest account, if it was enabled on the old system. Test. If the problem is still there, the cause is external to the machine, or else you're dealing with a bug or a hardware fault.
If the problem is resolved, reinstall your third-party software cautiously. Self-contained applications that install into the Applications folder by drag-and-drop or download from the App Store are safe. Anything that comes packaged as an installer or that prompts for an administrator password is suspect, and you must test thoroughly after reinstalling each such item to make sure you haven't restored the problem. -
I can't hear my callers but i hear them sometimes. It makes some weird cracking sound.
Apple just announced new products. It is ALWAYS busy this time of year. You just have to deal with it.
Alternatively, you can contact Apple Support and get assistance that way. Worst case scenario, they'll require a $19 fee to troubleshoot your device over the phone, which is refunded if it turns out you have a hardware issue.
Try them at https://getsupport.apple.com or 1-800-MYAPPLE and see if they can help.
But also try this:
Basic Troubleshooting Steps when all else fails
Quit the App by opening multi-tasking bar, holding down the icon for the App for about 3-5 seconds, and then tap the red circle with the white minus sign.
Relaunch the App and try again.
Restart the device. http://support.apple.com/kb/ht1430
Reset the device. (Same article as above.)
Restore from backup. http://support.apple.com/kb/ht1766 (If you don't have a backup, make one now, then skip to the next step.)
Restore as new device. http://support.apple.com/kb/HT4137 For this step, do not re-download ANYTHING, and do not sign into your Apple ID.
Test the issue after each step. If the last one does not resolve the issue, it is likely a hardware problem. -
Motherboard not geting past MSI logo display - please help me if you can
Hello all
I have recently purchased a motherboard kit from a very respected retailer so all my components are compatible. It consisted of an MSI KT4V motherboard, an AMD Sempron 2600, a stick of 256MB DIMM, and a heatsink. I have installed them all as best to my knowledge but on booting up for the first time all I am getting is what looks to be an MSI logo screen. I have changed the jumper switches and tried other things but I am unable to get to the BIOS or anything.
Has anyone else had this problem or does anyone know of any methods I could take to try and resolve it ?
ThanksHello again.
First can I just say thanks to everyone who has posted a reply to me here. I have brought my motherboard manual in for any specifications that is needed, unfortunately my power supply is back at my flat but it came with a chassis I bought from a different company. I know it's 400w if that's any consolation.
Please understand that I am unable to get anywhere near BIOS - literally as soon as I power it up the power light comes on, you can hear the hard drives whirring, the DVD ROM spins, etc. but almost instantly an MSI logo is displayed on the screen and from there I can;t do anything. I am not given the chance to do anything before. Hitting Del does nothing, in fact the keyboard doesn;t even light up at all when I switch my computer on, almost as if it doesn;t recognise it or it doesn;t get as far as reading it or something. Surely there can;t be a problem with my graphics card as I'm guessing I wouldn't be able to see the dreaded MSI logo. I reseated most stuff like the RAM and swapped IDE cables etc. and that seems fine. I am really getting sick of seeing that infernal MSI logo screen !! -

Hello,
I am learning Java at college, but when I try to do it at home on my computer I get an error.
Can someone please help me as I need to do my coursework very soon and I'm not very good with gadgets and things.
The error is like this:
I type this in -
C:\Java
And it says this back -
'Java' is not recognized as an internal or external command,
operable program or batch file.
I tried different spelling and making it all capital letters but it is still broken.
Thank you all very much for helping,
Sally.Ok, I have read the sun site and downloaded the JDK and saved it to disk in the C:\ drive.
However I still get the same error so I think I must be very stupid and I think the computer knows that. -
Export Problems - PLEASE HELP! Thank you.
Firstly many thanks for reading this post and any replys you may give.
This is the first time I have used motion and am having a little trouble exporting my movie in the correct format. The finished movie needs to be put onto DVD for playback through a standard PAL player onto a 28" wide screen LCD at an exhibition. After searching the net I found what appear to be the correct settings, which are 720x576 PAL DVD/Anamorphic 1.42.
The Movie looks great in Motion and everything is at the correct proportion. When I just do a standard quicktime export the finished movie appears to be squashed width ways as to fit on to a standard tv. I have played around with various export setting and it always comes out the same and I can't see any tabs to tick on output setting which renders the 1.42 anamorphic setting.
I am using Motion version 1 and the movie contains just still images that fade and mask. I have noticed you can set each imported image to a certain aspect ratio, but I don't imagine this would effect the exported movie.
Any advice or suggestions would be greatly appreciated.
CheersHi mate,
Just had the same problem myself working in Motion for Titles for a film in FCP. Basically the way I see it you mean like me when the clip from motion comes into FCP it is displayed as a square image whereas everything else on the timeline is Anamorphic. I ve spoken to Apple pro app support on the phone and its a very simple solution:
Right click the clip in the browser and go to 'Item properties' then 'Format' then scroll down to 'Pixel Aspect Ratio' and simply click the two collums and a tick will appear. Now if the clip was already in the timeline delete it and put it back or just drop the clip on to the timeline and it is displayed as Anamorphic like everything else.
Hope this helps you or anyone else with the problem.
Regards

DavidIHello DavidI.
Verify/repair the startup disk (not just permissions), as described here:
The Repair functions of Disk Utility: what's it all about?
After having fixed all filesystem issues, if any, proceed as follows to try to identify the problem:
1. Open /Applications/Utilities/Console.
2. From the File menu, choose either Open Console Log, or Open System Log, or both, so that the Console application displays the contents of both system.log and console.log.
3. In the Finder, go to /Applications/, and try to open Mail by double-clicking on it. Look at the bottom of the Console windows for messages that might be written there as a result. They may provide some clues as to what the problem is.
In the meanwhile, take a look at the following article, in case this is a font issue:

Its been going great for some time (months) and last two days Ive hit a bump.
We tracked it down to being nexus; (au instrument) however even disabled or removing the .component makes logic crash & Freeze.

Im unsure what to do.
Can someone shed some light on my situation?
Thank youI will try it tonight when Im home.
Do I completely remove all AU stuff and go all from scratch? I dont mind doing so if it works again.. Alot of au's to install..
