Hi Experts,
How can we get the URL of currently opened web page/tab in a java class.

Best regards,
Eswar

You can't write spyware in Java.

In an applet, the getCodeBase() or getDocumentBase() methods

Why isn't it possible?

Yes, if you got the wits. Just attach a heavy duty rocket on one, then sure. I'd suppose it's the same with java, cept not with a heavy duty rocket. For instance, java may not directly be able to get the currently open webpage from external browsers, but who's to say these browsers don't / can't be made to export said information readily available for java? And this is only one way of going about it. Couldn't you just translate network information from your computer and get the required information that way?

I don't know much about java, for sure, but I fail to see why this would be impossible when an URL is only a simple String of data.

why this would be impossible

The contents of the data is not relevant. Getting any byte from any location in any program's memory sounds simple.

Does it have to be bytes in memory? Is there no automatic export, API or anything for browsers, or OS interface for your IP traffic you could translate?

**Norm** · 03-14-2012, 09:22 PM

If the bytes are not in memory, where are they?

**MonkeyMan** · 03-14-2012, 09:26 PM

I mean, do you really have to go get bytes from memory?

This is just an example. Mozilla firefox could have an addon that exports your current url to a file. Java could pick up that file and make use of it, hence getting the URL.

Your OS could track your network traffic, see the IPs you are connected to and export them again to a file, where your java could pick it up and make use of it.

I don't see why you should go tampering with memory and getting bytes, when you could just do with exports.

All you really have to do is get the applications play nice together. Making addons for browsers that export your current URL every time you change the page shouldn't be an issue as far as I know?

None of that has anything to do with java programming.

**MonkeyMan** · 03-14-2012, 09:32 PM

It does if you plan on using the URL information in Java. However, if you plan on using java just you fetch the information directly from the source and nothing else, then I could see why it's a problem. However, getting URL data altogether shouldn't be.
