So bad,problem still exist.

Hi Kevin,
how did you fix this? We´re experiencing the same problem. Web Start refuses to start any ws-application on some of our computers. De- and re-installing JREs or JDKs didn't help.

I'm trying to delete multiple pix in iPhoto that i stupidly made duplicates of without knowing, I've tried going into the applications folder and using image capture but i think I've missed a step , can anyone send the correct info / steps pls thanks

I'm trying to delete multiple pix in iPhoto that i stupidly made duplicates of without knowing, I've tried going into the applications folder and using image capture but i think I've missed a step , can anyone send the correct info / steps pls thanks

again image capture is not involved with deleting photos from iPhoto in any way ever
the paid version of iPhoto Library Manager is very good for finding duplicates as is Duplicate Annihilator
And I have no idea who told you this - or what it means - but re-read both of my opening statements
I was told I could delete multpiles thru image capture by transferring my iPhoto library etc

Whenever I update my iPhone software, it asks me to sign in to iCloud with an old email address. My other devices all have the correct address. How can I get the correct address for my iPhone? The only Apple ID that works for logging in is my new one.

Whenever I update my iPhone software, it asks me to sign in to iCloud with an old email address. My other devices all have the correct address. How can I get the correct address for my iPhone? The only Apple ID that works for logging in is my new one.

To change the iCloud ID you have to go to Settings>iCloud, tap Delete Account, provide the password for the old ID when prompted to turn off Find My iPhone (if you're using iOS 7), then sign back in with the ID you wish to use. If you don't know the password for your old ID, or if it isn't accepted, go to https//appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Tap edit next to the primary email account, tap Edit, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iPhone on your device, even though it prompts you for the password for your old account ID. Then go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https//appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

In lion can I clear the list of applications that have requested Location Services under System Preferences...Security

In Lion, can I clear the list of applications that have requested Location Services under System Preferences...Security & Privacy…Privacy?
I have uninstalled an application but the name of the app is still showing up in this list of apps. I have disabled it but was wondering if there is a way to remove it from this list.

I don't believe you can since it is populated automatically by the system. FWIW, I do not have location services enabled - I chose not to since I have no intention of tucking my 27" under my arm and taking it somewhere. And, I deny any request any app wanting to use it and have not experienced any error messages because of it.

How can I Locate the correct filepath in a jsp page?

In http://localhost:8080/myweb/a.jsp, I will call a java bean file which is locate in http://localhost:8080/myweb/WEB-INF/classes/haha/DBConnection.class. This java file requires to read an external file which locates in http://localhost:8080/myweb/WEB-INF/classes/haha/db.txt
My question is how can I get the correct filepath in this environment?
inputStream = new BufferedReader(new FileReader(????????));
Only this will work
inputStream = new BufferedReader(new FileReader("D:\Program Files\Apache Software Foundation\Tomcat 5.5\db.txt"));
But no one will place the file here, and it is impossible to do this when upload to 3rd party hosting.
Any suggestion? thx.

Thx all, in a jsp page, calling this method is fine.
ServletContext s = getServletContext();
String a = s.getRealPath("/");
In a Servlet file, below method is ready to use:
String b = getServletConfig().getServletContext().getRealPath("/");
My problem is, I have a jsp page, which initialize a java bean , this java file is responsible for Database Connection, which will read the external text file to get the login, password and database name. So I won't need to recompile this file every time when I place in different platform with different configuration. I only need to edit the text file is ok.
But How can I get the absolute file path when that jsp page initialize that java bean file? Below is my error, any suggestions are thx.

How can I know the version of Application Server Java Virtual Machine

How can I know the version of Application Server Java Virtual Machine?
Thanks a lot.

Thats easy. Your jdk/jre are located in the App Server home directory. Just run the java command under the jdk directory with the "-version" switch and it will provide you with detailed information about your VM.
For example if you're doing it at command prompt it will be something like
java -versionI hope this will be useful to you.

HAVING TROUBLE SAVING ITEMS IN LION AS IT IS DIFFERENT THAN SNOW LEAPORD... CAN ANYONE SHARE THE CORRECT PROCEEDURE?

I'M HAVING TROUBLE USING THE SAVE FEATURE IN LION AS IT'S MUCH DIFFERENT THAN THAT IN SNOW LEAPORD, CAN ANYONE SHARE THE CORRECT PROCEEDURE TO SAVE A DOCUMENT?

Revert back to Snow Leopard would be the ideal choice.
Not writing in all caps would be nice too, it's SHOUTING
Thirdly, Lion introduced auto-save, so you have to duplicate the file, then open the duplicate to make changes.
Wonderfully asinine.
Quit the program, it will ask you to save.

Help:How can I run the J2EE Client Application? Thanks

Help:How can I run the J2EE Client Application that will access the remote J2EE1.4 application server which runs on another host computer?
I have developped a stateles senterprise java bean name converter and deloyed it in the j2ee1.4 application server on the host machine A. The converterbean provides the remote home interface and remote interface. At the same time I have developped the j2ee application client named convertappclient. When I access the conveter bean at host computer A through the script 'appclient.bat' as 'appclient -client convertappclient.jar', the client can access the bean sucessfully. Now I want to access the bean through the script 'appclient.bat' at host computer B,what files should I copy from host computer A to host computer B;and what the command line should be like? Thanks!
The following are the code of the enterprise java bean and it's home interface .
The client code is also provided.
The enterprise java bean:
package converter;
import java.rmi.RemoteException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
import java.math.*;
public class ConverterBean implements SessionBean {
BigDecimal yenRate = new BigDecimal("121.6000");
BigDecimal euroRate = new BigDecimal("0.0077");
public ConverterBean() {
public BigDecimal dollarToYen(BigDecimal dollars) {
BigDecimal result = dollars.multiply(yenRate);
return result.setScale(2, BigDecimal.ROUND_UP);
public BigDecimal yenToEuro(BigDecimal yen) {
BigDecimal result = yen.multiply(euroRate);
return result.setScale(2, BigDecimal.ROUND_UP);
public void ejbCreate() {
public void ejbRemove() {
public void ejbActivate() {
public void ejbPassivate() {
public void setSessionContext(SessionContext sc) {
The bean's remote home interface :
package converter;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
public interface ConverterHome extends EJBHome {
Converter create() throws RemoteException, CreateException;
The bean's remote interface:
package converter;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
import java.math.*;
public interface Converter extends EJBObject {
public BigDecimal dollarToYen(BigDecimal dollars) throws RemoteException;
public BigDecimal yenToEuro(BigDecimal yen) throws RemoteException;
The j2ee application client:
import converter.Converter;
import converter.ConverterHome;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import java.math.BigDecimal;
public class ConverterClient {
public static void main(String[] args) {
try {
Context initial = new InitialContext();
System.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url","jnp://10.144.97.250:3700");
Context myEnv = (Context) initial.lookup("java:comp/env");
Object objref = myEnv.lookup("ejb/SimpleConverter");
ConverterHome home =
(ConverterHome) PortableRemoteObject.narrow(objref,
ConverterHome.class);
Converter currencyConverter = home.create();
BigDecimal param = new BigDecimal("100.00");
BigDecimal amount = currencyConverter.dollarToYen(param);
System.out.println(amount);
amount = currencyConverter.yenToEuro(param);
System.out.println(amount);
System.exit(0);
} catch (Exception ex) {
System.err.println("Caught an unexpected exception!");
ex.printStackTrace();
}

My current system is OS X 10.4.11 and I need a 10.5 to update my iPhone, where can I download the correct 10.5 update?

Hi, and welcome to Apple Support Communities.
You can't download Mac OS X 10.5; you need to purchase it.
Which exact iBook model is it?
You can choose from this list:
http://www.everymac.com/systems/apple/ibook/index-ibook.html
Not all iBooks are compatible with Mac OS X 10.5, so we need to know which iBook you have.

Hi, can you help? My emails that I have received show the date received as either today, yesterday or July 28. How can I get the correct date received?

Hi, The emails that I have received show the date received as either today, yesterday or July 28. How can I get the correct date received?

That's very scary. They might do it, but I personally have never had Apple contact me re id's except on their site when signing in. I suggest you DO NOT respond until you have a phone conversation with Apple security. They can verify if they sent you the e-mail and why.
While it's very possible it's true,again, I suggest you not respond until you speak to someone at Apple. I've often read here that when people sign in they are not allowed to because "someone else has used the id" type of statement.
Also, you should be able to go to the app store and see what apps you have downloaded.
Though it could have been a free app, have you checked to see if any were bought with your id account?
I've gotten these types of e-mails from places like USPS and FedEx which look amazingly authentic and were from their website. I also received an odd e-mail from my cousin in Ireland last year that clearly was not from him. It was also sent to others in his family in Ireland. I e-mailed him that I only opened it because it had a .ie, but suggested he change... Days later I received mail from 'him' - same name, but at yahoo.com.
Again, I would call Apple. You can also report it at [email protected], but I would not settle for that given your situation. If nothing else, call Apple sales (sales depts. anywhere answer fast) and ask them to transfer you to security. Apple will not want anybody accessing their name, and while it's unlikely, it's not impossible that it is someone phishing.
Hope this helps and can you let the support community know your results by posting on this thread when you're done? Thank you.
Hope this helps.

On new IOS 7, when I message contacts, it selects thier old contact number, despite the fact I have deleted/edited their number in my contacts list. Only by going through contacts, can I message the correct number. The old number does not appear there, so I am unsure where "messages" is picking up the old number, it doesn't appear that "messages" is synching with "contacts". Any ideas how to fix this?

Can't find the Video Chat application on my PlayBook

Hey all,
I live in Saudi Arabia, I'm only stating where I live cause I have a feeling that this might be the reason of my problem. Anyway I can't find the video chat application icon on my playbook although I've updated its software to the latest OS 1.0.7 ---- I hope some1 help me with that cause I need this application desperately.
Thanks

it may not be available to customers in saudi Arabia, if so do security wipe setting up with a proxy server in the US or Canada. This way you will have the video chat software.

Can I use the Disk Utility Application to backup bootcamp windows 7?

Can I use the Disk Utility Application to backup Bootcamp that has Windows 7 on it? If I install a new blank drive, I would like to know that using Time Machine I can get the MAC OS back and using the Disk Image Utility I can restore Bootcamp with Windows 7.

NO.
You have to use Windows or a Windows utility.
There are programs that will clone an entire drive (sector) as well.
DU does not though. Paragon does support Boot Camp.
