Hi,

I have a "Test.html" file and other supporting directories in "MyFolder"

In Test.html file I have the following tags with other text..

<applet id="listF" code="AppletClass.class" width="1" height="1">
<param name="archive" value="listfiles.jar">
</applet>

In listfiles.jar, i have a class file called as "AppletClass.class"

In this file (AppletClass.java) I am writing following code

/*where folder1 is one of the dependent folder residing with "Test.html"*/

File f=new file("folder1");
File f1[]=f.listFiles();

After adding these lines i repackaged to jar file and accessed Test.html

Now i am getting the following error..

java.security.AccessControlException:access denied (java.io.FilePermission folder1 read)

I check, the folder doesn't have any permissions.

Please let me know how to list the files and get solution for this problem...

By default, applets can't access the local file system as a security measure. To get around that, they need to be signed, or the local security policy altered. See HowCanAnAppletReadFilesOnTheLocalFileSystem for details.
