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

Changing the browser location in Java

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.

Accessing JAVA webservice from ASP [modified]

31-Jul-08 2:42

Hi,

The porpose of this is script is to get the value of a select box and then go to a page based on this selection.

For form.cat.options[form.cat.options.selectedIndex].value:

form is a form that is called "form" and "cat" is a select box. What this line does is get the value of the selected option in this select box, which is what form.cat.options.selectedIndex is for - the []s show that form.cat.options is an array. This value is stored in a variable called "val".

What the next line does redirect the current browser window to "postquery.php" with the argument "cat" being the val variable that was assigned in the first line.

For example, if "val" was "data", then the browser window would be redirected to "postquery.php?cat=data".

Hope this helps,

Just add the web service as a web reference to your project, and it creates a class that you can use to call it.

Despite everything, the person most likely to be fooling you next is yourself.
