Having trouble with my java applet in IE

When i try to make my applet work in internet explorer it just comes up with a blank grey box and an error message saying:
load: class classname not found
Does anyone know how i can correct this?

<APPLET code=bobTheBasher.class width=600 height=400></APPLET>and there is a class called "bobTheBasher.class" in the same folder as the HTML file?
The HTML bit's fine BTW

I am having trouble with my JAVA Applet. It isn't functioning on SAFARI. It seems to have stopped working and I used it on SAFARI last year. Any suggestions ?

Issue with running Java applets on Safari 6.1

I conducted a system capability check on the course site I access (Defense Acquisition University) and one of the results indicated that I do not have the capability to run applets (requirements to run all courses). I verified my setings and I do have Java ver. 7 update 45 installed. I verified Safari's security preferences and confirmed that the "Enable Java Script" is checked. I tried configuring the website settings for Java plug-in but cannot figure out how to add url on the configured websites box. Is there any way to enable running applets in Safari? Any help is appreciated. Thanks in advance.

Having trouble with throws...

Hey there.
I'm fairly new to java so bear with me here.
I'm having trouble with a program that, in short, reads from a file.
Let me shorten a show the code to you...
//main opens up and in a bit we get to...
if (loginVerify())
//and the if continues.
fileIn.close();
//main ends
public boolean loginVerify() throws IOException
     openIn(); //Checks for validity - It's a long story why I //didn't just put the code in loginVerify(). I //don't think it should matter.
String str = verifyLog(); //Does the actual reading
     str = str.substring(1);
     if (str == placeHold) //Don't worry about not making placeHold,
//I made it global for testing reasons.
          return true;
     else
          return false;
private String verifyLog() throws IOException
     String str;
     while (true)
          str = fileIn.readLine();
          if (str == null)
               break;
          else if (str.charAt(0) == 1)
               return str;
          //ADDITION OF OTHER NUMBERS
          else
               return str = "invalid";
private void readIn() throws IOException
     BufferedReader console =
new BufferedReader(new InputStreamReader(System.in));
openInputFile(fileName);
if (fileIn == null)
System.out.println("*** Can't open " + fileName + " ***");
return;
private static void openInputFile(String fileName)
try
fileIn = new BufferedReader(new FileReader(fileName));
catch (FileNotFoundException e)
So it's fairly simple. It checks for validity and then reads lines until it finds one with the first char as '1' when it finds it, it reads the rest of the line off.
The error I'm getting is as follows: Exception java.io.IOException must be caught, or it must be declared in the throws clause of this method.
I've added throws IOException to them in attempts to fix the error but to no avail. I've tryed putting the catch in different spots... again, doesn't work.
I'm using codewarrior IDE version 5. I'm fairly sure it's the newest. I installed Java SDK 1.3 with codewarrior originally but I installed 1.4.1 recently.
If you need to see anything else about it, please tell me. I'd be more than happy to post a little more if it'll help.
Thanks

Ok. I worked through a bunch of throws and now I've found one I can't seem to conquer.
private String verifyLog()
     String str = "";
     while (true)
          try {
          str = fileIn.readLine();
          catch (FileNotFoundException g) {
          if (str == null)
               break;
          else if (str.charAt(0) == 1)
               return str;
          //ADDITION OF OTHER PEOPLE
          else
               return str = "invalid";
     return str = "invalid";
}This time the error is at the reference to readLine() and it tells me the same error as before. I have a catch set up there, don't I?
readLine() is something I didn't create so I don't know how I'd tell it to throw an exception if I had to...
Thanks

Having trouble with packages

I am having trouble getting a java program to see a class that I put in another module.
The first module is this DMTest.java:
package mypackage;
public class DMTest
public DMTest()
    System.out.println("Hello");
DMTest.java compiles correctly, and I put it in the "mypackage" directory. Then I try to compile Tester.java.
import mypackage.*;
public class Tester
public static void main (String[] args)
    DMTest mTest = new DMTest();
This gives me a compile error as follows:
Tester.java:27: cannot resolve symbol
symbol : constructor DMTest ()
location: class DMTest
    DMTest mTest = new DMTest();
                             ^
1 error-------------------------------------------------------
Does anyone know what is wrong with my programs? Thanks!

The only way I can recreate your exact error condition is to change the DMTest constructor to require a parameter. When I then compile Tester, I get the error because the compiler does not find the no-argument constructor.
This tells me that whatever version of DMTest that the compiler finds when processing Tester, it does not have a valid no-argument constructor.
I would try a couple of things:
1) Delete or rename DMTest so it does not exist. Attempt to compile Tester. The error should be different. If it's not, then there is another version somewhere. Run a Windows Find for DMTest.* on all your drives. If you find others, there may be a classpath issue.
2) Add a main method to DMTest with the same contents as the main() in Tester. Compile and run DMTest. This should help separate the import issue from the constructor issue.
If you try these, please post the results. This one is a puzzle!

Troubles with launching Java GUI from C++

Now here's the interesting thing: in the constructor of my Java class there's a call to pack() to initiate my Java GUI. When I remove that call everything works fine (but then I haven't got a GUI though). setVisible(true) in the Java code also gives that problem.
Has C++ or the Xm library some troubles with the Java GUI? Or what the hell is going wrong?
PS: On Solaris, the very same code works perfectly...

I really need a solution.
Is it possible it has something to do with threads?
Do I have to do AttachCurrentThread or something like that? Is that necessary?
Btw, I assigned 10 duke dollars to this topic.

Hello Sue,
I have an iPad 3, iPad Mini and iPhone 5S and they are all sluggish on capitalisation using shift keys. I hope that Apple will solve the problem because it is driving me crazy.
I find using a Microsoft Surface and Windows 8 phone, which I also have, work as well as all the ios devices before the ios 7 upgrade.
It has something to do with the length of time that you need to hold the shift key down. The shift key needs to be held longer than the letter key for the capitalisation to work. For some reason, this is a major change in the way we have learnt to touch type on computers. I am having to relearn how to type!

I'm having trouble with something that redirects Google search results when I use Firefox on my PC. It's called the 'going on earth' virus. Do you have a fix that could rectify the vulnerability in your software?

I'm having trouble with a virus or something which affects Google search results when I use Firefox on my PC ...
When I search a topic gives me pages of links as normal, but when I click on a link, the page is hijacked to a site called 'www.goingonearth.com' ...
I've done a separate search and found that other users are affected, but there doesn't seem to be a clear-cut solution ... (Norton, McAfee and Kaspersky don't seem to be able to detect/fix it).
I'd like to continue using the Firefox/Google combination (nb: the hijack virus also affects IE but not Safari) - do you have a patch/fix that could rectify the vulnerability in your software?
thanks

I am having trouble with my Mac Mini's ethernet connection. Defining a new network interface shows no ethernet adaptor. Reloading SL from DVD repaired. But SL update lost ethernet again. Will Lion Fix?

I am having trouble with my mac mini ethernet. It had been working for weeks after an update to SL 10.6.8.
Once it went out and i repaired it by defining a new connection from System Preferences ->Network->(left panel service, +).
But yesterday, after a power up. my ethernet was not working again. I tried this old trick to repair it, but the interface choices
listed for '+' a new service did not include Ethernet any more. And the Utilities->System Profiler->Ethernet Cards shows
no ethernet available.
As a last ditch effort i reloaded my original SL from DVD. (I think it was version 10.6.4 but i could be mistaken on the version).
The ethernet worked! But KeyNote wasn't going to work because apparently the version i purchased depends on 10.6.8.
So I upgraded again to SL 10.6.8 (Plus some other updates like AirPort which i don't use).
Now the Ethernet is not working again. I see the same symptoms as before with the Ethernet seeming not installed.
Is this a problem seen by others?
Would going to Lion fix the problem?
Could AirPort actually be the culprit and not SL?
If i stay with my original SL, would i need to repurchase a version of KeyNote for the older version of SL?

Have you reset the SMC?
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
While you're at it, resetting the PRAM won't hurt anything and 'might' help is SMC reset didn't work (PRAM does some port control):
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Something else you might try .... you don't say how you're updating to 10.6.8, however, if you're using Software Update, you might try downloading the 10.6.8 combo update, which contains all updates to 10.6. Sometimes, Software Update doesn't work quite right, and installing the combo update fixes that. Download the update from Apple's download site at http://support.apple.com/downloads/ , using Disk Utility repair permissions, apply the combo update, then repair permissions again.

I am having trouble with some of my links having images. For example, Foxfire has a picture that looks like a small world. The links in question are blank.

I am having trouble with my links/websites having images attached to them. The place where the image should be is blank. For example, AARP has an A for its image. My storage website has a blank broken box where the image should be. I forgot I had trouble and had to reset Foxfire, this problem occurred after that reset.

cor-el,
Mixed content normally gives the world globe image, unless you are using a theme that uses a broken padlock instead. Maybe the gray triangle means invalid? I came across that in a few themes (what is invalid was not made clear), but those were not using triangle shapes to indicate that.
I came across that mention in one of the pages you posted:
* https://support.mozilla.org/kb/Site+Identity+Button
I cannot attach a screenshot because I have not seen a triangle of any kind in my address bar.

I have an Ipod Touch (4th Gen) and I am having troubles with my downloads from purchasing music from the Ipod. On my downloads icon in the Itunes Store (on Ipod) there is a symbol of how many songs I still have waiting to download, but they wont download.

I have been having troubles with this for months and am extremly tired of not being able to download my songs. I bought these songs off of Itunes as well, so I really hope i can retrieve them. I do not know where to find a personal apple support person yet, does anyone know where to find one on the website?

iMessage and FaceTime went down yesterday for some people. Mine is still down. My iMessage is saying the same thing about being activated. Sounds like you are still down too. Ignore the status page that says everything is fine - it lies.
