My AppleTV will not show the main menu but it will airplay

We have been airplaying music from my iphone to the appleTV all week and now we cannot get any video other than in airplay. The devices are all off of airplay. We have restarted the appleTV, unplugged and replugged the HDMI cords. To no avail.

Try holding menu and left arrow keys onteh remote TOGETHER for 6 secs - does that let you navigate?

I have changed to AT&T U-verse, which has a new modem and router combined. Safari 5.1.10 will not recognize the wifi signal, but Foxfire will. What settings do I need to change on Safari?

Hello SalsburgD
The first thing I would check is to make sure that the router is using the recommended settings to get online. Another troubleshooting step is to create a new Network Location and then join your network to see if that changes things.

You can use these steps to check if images are blocked:
*Open the web page that has the images missing in a browser tab.
*Click the website favicon ([[Site Identity Button]]) on the left end of the location bar.
*Click the "More Information" button to open the "Page Info" window with the Security tab selected (also accessible via "Tools > Page Info").
*Go to the Media tab of the "Tools > Page Info" window.
*Select the first image link and scroll down through the list with the Down arrow key.
*If an image in the list is grayed and there is a check-mark in the box "Block Images from..." then remove that mark to unblock the images from that domain.

There are also extensions (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images.

TS1398 My safari will not open the msn website but it will open all of the other msn websites like "entertainment"' , "sports" , "auto's", etc.

My safari will not open the msn.com site but it will open the other msn websites like "entertainment" and " sports". What to do?

There have been a few users talking about this for the past few days. I have no problems at all with it using Safari or iCab Mobile. This sequence has worked for most of the user that have tried it however, YMMV.
Try this.
Quit the Safari app completely and reboot the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
And do this as well. Go to Settings>Safari>Clear History, Cookies and Data. Clearing history is not a necessity, but clear cookies and data.

You have to specify the manifest with a special option (I think its was -M)
Otherwise the jar will create one (even if you provide it)No, the text file passed as a parameter will be incorporated in the manifest file generated by the JAR tool.
@OP: This will work:
JarTest.java
public class JarTest {
public static void main(String[] args) {
System.out.println("JarTest works!");
}manifest.txt
Main-Class: JarTest+(note there is an extra new line in the manifest.txt!)+
Now execute these commands:
javac JarTest.java
jar cfm MyJar.jar manifest.txt JarTest.class
java -jar MyJar.jar And on my machine, the string "JarTest works!" is displayed on the screen.
And if you look in the MANIFEST.MF file inside your jar file (you can use almost any zip-utility for this), you will see the following:
Manifest-Version: 1.0
Created-By: 1.6.0_0 (Sun Microsystems Inc.)
Main-Class: JarTestOr something similar.

Hello,
I am a French person. Excuse me for my English who is not perfect.
I seek to create an achievable "jar". I followed the instructions given in the url http://java.developpez.com/faq/java/?page=execution#creationJar, and on the site of Sun.
I have today only one class which I posed in a specific repertory "Class".
Appli
|__Class
|__Src
|__META-INFThe contents of my "Manifest" is stored in repertory META-INF with the name "Commission2007.MF" and its contents are as follows:
Manifest-Version: 1.0
Created-By: 1.5.0 (Sun Microsystems Inc.)
Main-Class: Commission2007
.I've left the space line at the end of the file.
Here the result of execution of my order "jar":
C:\#Java Dev\2007_Commissionnements>jar cvfm Commission2007.jar META-INF/Commission2007.MF -C Class/ .
manifest ajout�
ajout : Class/./(entr�e = 0) (sortie = 0)(0% stock�)
ajout : Class/./Commission2007.class(entr�e = 9060) (sortie = 4547)(49% compress�s)I controlled the assignment of the extension "jar" in "Working station = > Tools = > Files Option = > Files Type = > .jar Selection = > Advance =
Open = > Change = >" C:\Program Files\Java\jre1.6.0\bin\javaw.exe "- gravel bank" %1 "% *". Thus not of problem on this side there!When I double click on the file "jar" lately created, I have the error message according to: "Could not find the main class. Progam will exit. " I do not understand the reason of this error. I consulted all the subjects on the treating Net of this subject but without result. I thus call upon you.
Perhaps that the cause is in my code which however functions perfectly when I carry out it with the order: "Commission2007 java". The class "hand" is quite present to see the code below. You can find the totality of my code on the bond http://www.developpez.net/forums/showpost.php?p=1870361&postcount=74

     �

          Commission2007 editer = new Commission2007();
          editer.show();
          editer.addWindowListener(editer);
}I thank you in advance for your assistance.
Cordially, Gilles.

Salut,
It has been my experience that it is never a good idea to name your .MF file anything else other than MANIFEST.MF.
Try naming your .MF file MANIFEST.MF and rebuild your JAR.
Bon chance.

Try going to the following
Tools->Web Developer-> Page Source.
You can also access this by way of keyboard shortcut Ctrl + U
The View Page Source option is also available via the right-click menu by just right-clicking inside the page window & it will be the penultimate menu item.

Help Me Urgent...Error: "Could not find the main class. Program will exit."

Am using Eclipse 3.3.2
I have a project called: SWDS
Initially i have JDK1.6 installed in my system. At this time the project is running succesfully.
But when i removed(uninstalled and environment path also removed) JDK 1.6 and installed JDK 1.5 and path also given.
No changes are made in the project code.
When I Run the project SWDS then showing an alert "*Could not find the main class. Program will exit*" and then getting error messages like:

Pleez help me how to rectify this error.

The manifest file is missing from the project.
I searched the net and read about the manifest file and I saw that it is supposed to be located in META-INF/MANIFEST.MF. I suppose that means project_root/META-INF/MANIFEST.MF, right ?
I am asking this because I haven't got that much experience in Java and this is the first time I hear about a manifest file.
Does anyone have any Ideea how I add a manifest file to a project with Eclipse SDK? I searched the menus and I didn't find anithing of such sort... o
Does Eclipse have support for editing manifest files at all?

Any Ideas? I did a search on google, and looks like others have had this problem but found no answer.

There could be several reasons for getting this "Could not find main class" error message. From your stack trace it looks like the class javax/media/ControllerListener is not in your class path. Make sure your manifest file has a line like this:
Class-Path: pathToTheJarFileWithControllerListenerClass.jar otherJars.jar
This error message is also generated whenever any static initialization errors out giving the misleading error message implying that there is something wrong with the main class. Prior to starting your main class, static initialization of any static variables takes place. In my case, I was initializing a resource bundle, and forgot to include the property file in my building of the jar file. Well this failed of course and the generic error message appeared. It took many long hours to figure out it didn't have anything to do with the manifest file or the main class itself.

That message is listed in two scripts on the bank's site. One function that can display the message is named PhotoRotator and the other is named PromoRotator. However, I can't seem to trigger the error myself.
