Hi All!

Me again, still struggling and grappling with my java applet.
My problemetic code is as follows:

try{ LoginInputStream = new BufferedReader(new FileReader("Login.txt"));
    UserNameString = LoginInputStream.readLine().toString();
    PassWordString = LoginInputStream.readLine().toString();
    LoginInputStream.close(); }
catch(Exception ex) {}

All variables shown here have been correctly declared earlier, and the problem is that as the 'LoginInputStream' BufferedReader reads a file called 'Login.txt' the two string variables that it assigns the results to are not assigned a value at all, despite my toString() conversion!

I have tried it with and without the toString() conversion but the UserNameString and PassWordString values remain firmly as they were declared. (which was null)

Any help would be greatly appreciated!

Thanks!

Does the readLine() code execute or does the try statement fail and go onto the catch() branch?

Hi!

The 'try' code definatly executes, I tried this code with and without the toString() part:

try{ LoginInputStream = new BufferedReader(new FileReader("Login.txt"));
    	UserNameString = LoginInputStream.readLine().toString();
    	PassWordString = LoginInputStream.readLine().toString();
    	LoginInputStream.close(); }
  	catch(Exception ex) { UserNameEntryField.setText("Error"); }

And the UserNameEntryField TextBox remains empty.

Thanks

Try:

try {
  FileInputStream file = new FileInputStream("Login.txt");
  DataInputStream data = new DataInputStream(file);
  BufferedReader LoginInputStream = new BufferedReader(new InputStreamReader(data));

  UserNameString = LoginInputStream.readLine();
  PassWordString = LoginInputStream.readLine();
  LoginInputStream.close();
}
catch(Exception ex)
{
  UserNameEntryField.setText("Error");
}

The code above was based from this snippet

Hope this helps,

Hi!

Thanks but the code isn't working, even though it's perfectly valid. The error description says it all:

java.security.AccessControlException: access denied (java.io.FilePermission Login.txt read)

That is soooooooo annoying I could just scream! But I won't.

Is there any way i can get round the 'Access denied' problem?

Thanks!

I think you may need to change the Java IO file permissions; take a look at this.

Hope this helps,

Java if-else Problem!

Re: Java if-else Problem!

31-Jul-08 11:18

Hi All!

I'm having a problem with java if-else conditional statements, here's the code that's just not working for me:

public void actionPerformed(ActionEvent act) {

if (userName.getText() == MyString) {
   try {
   userUrl = new URL("http://www.mywebsite.co.uk");
    getAppletContext().showDocument(userUrl,"_blank");
   }
   catch(Exception e) {}
}

}

Where MyString is a string variable that has been declared earlier and userName is a TextField that is also declared earlier.
The actionPerformed code is being executed when I click the button in my applet but for some reason the code inside the if statement is never executed.

Do I have to use some kind of method on the MyString variable? Like MyString.value or something? (I've tried that by the way, no such luck Frown | :(

)

Thanks!

Try:

if(userName.getText().equals(MyString))

I believe that using == compares the two addresses of the strings as opposed to the actual value of the strings.

Hope this helps,

Right. Like C#, Java has a distinction between "value types" and "reference types". Unlike C#, the == operator is not redefined for the String type, so it's an address comparison.

create ad banner dynamically based on user inputs using javascript and
AJAX or are the any controls in AJAX for this functionality

Re: create banner dynamically based on user inputs and has to be stored in DB

Changing the browser location in Java

31-Jul-08 7:00

You would need to use a server-side language like PHP to render the banner based on custom input.

And AJAX is merely a set of technologies used together to dynamically receive content from a server - there are no "controls" in AJAX.

Hi All!

In JavaScript, changing the browser location is simple:

window.location = "myurl.html"

How would I accomplish this same effect from an embedded java Applet?

Thanks!

Use the Servlet Response sendRedirect() function, ie:

respose.sendRedirect(url);

Hi and Thanks!

Thanks for your help, however response.sendRedirect() is not working, my compiler complains and tells me that it cannot find symbol variable 'response'. Do I need to import something or use any other code in order for this to work? (I'm just learning Java)

Thanks!

Oh sorry I didnt realise you were new to Java. Yes, response is a HTTPServletResponse. See this article - it may be of help.
