[JavaForums]

Sometimes it is useful to store objects in files which can be read later. Object is saved along with its state. Simply saying, an object with its data can be saved in a file. Objects are made persistent this way.

java.io.FileNotFoundException

I have this error. I know it was talked about at the end of the last page of the article. But the problem is i still don't understand what that means and how to fix it. I would love more help. Thank you for your time

johnny, welcome to Java Forums!

I had some difficulty locating the "last page of the article", as I could only find one - the one that JavaForums linked to from above. Further, I had trouble finding anything regarding java.io.FileNotFoundException.

As you might be able to surmise, your error simply means your code literally can't find the file in question. Could you elaborate what it is you're having trouble understanding? Attempt to fix it by locating in your code, sometimes a literal string or path, "myFile.txt", "/home/captainmorgan/myFile.txt", etc. and confirm these file(s) actually do exist on your system or are where you are trying to retrieve it from. Lastly, if you are stuck, post some of your code in the General section of this forum titled New to Java, and be sure to code tags when posting your code, it makes for easier reading.

Best of luck.

Thanks Captian.

I have another error now. The problem is that i am not able to save on applets. I keep getting this error java.io.FilePermisson. The code works on normal java files, but it does not work on applets.

I have looked at some other sites, and i have discoverd this, when i tired writing to files on applets:

/**
* By default, this applet raises a security exception, unless you configure
* your policy to allow applets from its location to write to the file
* "writetest".
*/

How do i change the policy? Where is this policy file located, if there is one?
