Exceptions are not working. Is Java installed correctly?

This is the situation:
import java.lang.Exception;
public class ExceptionTest
    class ExtendException extends Exception
        ExtendException(String x)
            super(x + " is bad.");
    public static void main(String[] args)
        throw ExtendException("an error");
}Compiling it gives this error:
$ javac ExceptionTest.java
ExceptionTest.java:15: cannot find symbol
symbol  : method ExtendException(java.lang.String)
location: class ExceptionTest
        throw ExtendException("an error");
              ^
1 errorIf I take the throw line out, it compiles ok.
Is this a problem with the Java installation on my Mac? Or with my mind?

I get the same error declaring it static.
Furthermore, the following code:
import java.lang.Exception; // being maximal...
public class ExceptionTest
    public static void main(String[] args)
        throw Exception("an error");
}Has more or less the same problem:
$ javac ExceptionTest.java
ExceptionTest.java:7: cannot find symbol
symbol  : method Exception(java.lang.String)
location: class ExceptionTest
        throw Exception("an error");
              ^

  • Auto updates for VSTO addin not working that was installed using MSI

    I am not a .NET guy so this might be naïve question.
    We have developed an MS Excel VSTO add-in using Click-Once (VB .NET). Due to some business requirements, We packaged that add-in as MSI.
    DEVENV excel-addin.sln /Project AddinSetUp\AddinSetUp.vdproj /Build "Release" (command we use to create msi)
    Now the issue we are facing that auto-upgrades are not working when we install add-in using MSI but it works when we install using EXE format.
    Are we missing something during build?
    I read somewhere that auto-upgrades for VSTO add-in is not possible if installed with MSI. is it the case?
    Here is PropertyGroup content present in our vbproj file

    Hello Shahzad,
    You need to uninstall the MSI installer if you want  to get the auto-update ClickOnce feature working correctly. You can read more about MSI and ClickOnce installers in the following articles in MSDN:

  • Applets not working with Java 1.7.0_51 in MII 14.0 SP4 Patch 5

    Hi,
    I'm currently evaluating the migration of our MII 12.0 developments to MII 14.
    But I'm running in several issues just trying to use simple things like a SQL query template with an iGrid Display template in test mode.
    Used versions are: MII 14.0 SP4 Patch 5 and on client side the latest Mozilla Firefox with Java 1.7.0_51
    At first I always get a java security warning when the applet is being loaded about unsigned applications.
    At second the applet itself is not running. It always shows "No data available" and the java console shows the following errors (iResult is the id of the applet):
    iResult [ERROR] - Couldn't set query template: No Query Defined
    iResult [ERROR] - Couldn't set display template: null
    iResult [ERROR] - Couldn't set display template: null
    Is this perhaps a general problem, that the MII applets are not working with Java 1.7.x versions?
    If I call the same MII page from a client with Java 1.6.x it is working without errors.
    Do you have some suggestions for me?
    Regards Timo

    please clear your JAVA Cache. that should solve the JRE issue. thanks

  • Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install.

    Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install. Once I wrote my password, and for now on, everytime I start the session, another window advise me that "Java SE 6" is missing, due that, the computer can't run some "CS5Service Manager". If I try to install it, the download ends with an error. If finally, you skip the istallation, you arrive to the dock, but the menu bar at the top of the screen doesn't show up.
    In addition, my trackpad doesn't works either. I can move the arrow but i can't click anywhere, probably because the option of clicking by touching is disabeled and I can't performance a regular click.
    I'll be very glad if someone know what the heck is happening with my computer. Anyway, I'm going to the genius bar next Saturday. Thx!

    We're sorry.
    We can't find the article you're looking for.

  • Function keys are not working correctly

    I've been looking all over the various threads and I can't find an answer that solves my problem.
    Here are the details:
    I bought the computer in the U.S. where I live.
    I have a iMac 2.4GHz intel Core 2 Duo  EMC 2133 with a 20" screen. Bought it new in February 2008.
    I have Mac OS X 10.5.8  (I am waiting for my order for OS Snow Leopard to come in!!)
    I have been using a wireless mouse and Keyboard (Love not having cords!)
    Recently, my wireless keyboard got a short and quit working. I went down to the apple store and got a new wireless keyboard.
    I had the computer with me at the genius bar so, yes, the apple employee saw exactly what I have.
    I took it all home got the thing all put back together and got the new keyboard paired up and working with the computer.
    Here are the problems:
    Went to go use the function keys while using iTunes and found they weren't working properly. The F10, F11 and F12 do not control the volume of sound as the keyboard indicates they would, they instead activate dashboard, spaces, and application windows. 
    Following the advice of other threads, I looked over in the system preferences and made sure the "Use all F1, F2 etc." box was unchecked (it was unchecked), things still didn't work.
    I tried the fn key but it appears to not work at all it has no effect on the functioning of the function keys.
    I went under keyboard shortcuts in system preferences and found the F10, F11 and F12 keys, it confirms that those keys control spaces, dashboard and application windows as they are performing but shows no options to either reassign to volume control (as marked on the keyboard) or make the fn key work.
    I've gone back and forth trying various combinations of checked and unchecked boxes to see if anything would work, so far I've come up with nothing.
    A couple more important or interesting facts:
    Yes I have turned off and taken the batteries out of the old keyboard. My bluetooth connection currently shows it as disconnected.
    I have restarted the computer.
    One thing I find odd; when I go under preferences and go to Keyboard and Mouse when I go under the section "Bluetooth" it shows Bluetooth mouse with the name of the mouse and the battery level. BUT nothing is showing up under bluetooth Keyboard, I can't figure out how to change this and don't know if it is contributing to the problem.
    When I go under the bluetooth logo on the top bar I find the mouse and both keyboards referenced, the old keyboard is shown as disconnected and the other two are connected. I have tried to update the device's name but it doesn't seem to let me.
    I have double clicked on the device under bluetooth and it shows the new keyboard as discoverable, paired and connected. Hence, I am using the new keyboard to write this inquiry.
    Please, any assistance would be of great help. I have tried to be thorough in order help narrow the possible problem. Thanks!!

    Just thought I'd let you know.  Our suspicions were correct, it was the OS. After I installed Snow Leopard (10.6.8) all the problems were corrected.  I also updated the RAM from 1 gb to 6 gb. The mac is working all around better. Sorry it took so long to get back to everyone. My superdrive had pooped out. Rather than replace it I got an external drive from OWC connected with firewire 800.  So far everything is running very well, as far as I can tell this external drive is better than the original superdrive. My superdrive has always acted funny, infact I returned the first mac I got after a week because its superdrive was also malfunctioning. Anyway, all that to say everything seems to be fully functioning again.

  • After updating My iPad 2 to iOS 5.1.1 , my newly installed apps are not working.

    After updating My iPad 2 to iOS 5.1.1 , my newly installed apps are  not working . When I try to open the app the screen just flashes and then nothing happens. Built in apps works fine . Please help

    I realize that installing apps is not the problem. Installing another app from the app store is a recommended troubleshooting tip from Apple if all of the third party apps will not open. It resets your iTunes authorization when you install the app because you have to enter your password.
    If you didn't install another app try it. Read this support article as well.
    iOS: Troubleshooting applications purchased for the App Store
    Try this as well. Quit all apps, reset the iPad.
    Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open 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 to close the apps.
    Reset 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 - let go of the buttons.
    If that doesn't work - sign out of your account, restart the iPad and then sign in again.
    Settings>Store>Apple ID. Tap your ID and sign out. Restart the iPad.
    Go back to Settings>Store>Sign in and then see if the apps will launch.

  • My fonts are not working correctly

    Hello guys,
    I noticed today that most of my added fonts are not working. I use a lot of fonts that have a cyrillic subset which were working perfectly fine till 2 days ago. Now when I select a text field and try to change the font face to one of the added fonts, it changes the font face to whichever the default font is and renders the font selection menu to blank. I am really puzzled, the fonts are installed in the Fonts folder in Windows, and they were working perfectly fine till a couple of days ago. I havent installed any Fireworks or Windows updates in the meantime. I am working in Fireworks CS5.
    Cheers

    I wasn't sure about my shut-down-and-restart suggestion, but I still think it might be a good idea to clear the font caches.  Here are a couple links on clearing font caches for Windows and Adobe apps:
    http://www.ehow.com/how_7197467_rebuild-font-cache.html

    You might want to supplement this with some research of your own, then give it a try.

  • My pc has a virus I just downloaded song from pc to kids ipods now both ipods are not working correctly could the virus be in the ipods,  if not why are both not working doing the same thing right after unplugging from pc.

    Can an ipod get a virus from a pc that has a virus.  After connecting two different ipods to my pc to download music they both are not working correctly, could the virus have transferred to the ipod,  if not why would both ipods not work and be doing the same thing?  When trying to click on a game it just stays on the main screen.

    - I have not heard of a virus that can cause problem with an iDvice that has not been jailbroken.
    - Try resetting the iPods. nothing will be lost.
    Reset iPod touch:  Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Do you hve problems with one game? The same game on both iPods?
    Other apps?

  • Why the games are not working properly in my ipad after installing iOS7

    Why games are not working properly in my ipad in my iOS 7

    The games you mention would have been written and therefore designed for the previous version of iOS - you've most likely had a lot of updates lately in the run-up to the release of iOS 7 and if these games haven't had an update then chances are these will need to be adapted to iOS 7 by the developers if not working correctly.
