Loading Image Files in an Unsigned Applet from the Server

Sorry, i didn't find a proper Forum.

I want to load Image Files from the Server in the JApplet -

but everytime i try i get the message:

/Schadenskizze/classes/applet/pics/szenarios

access denied (java.io.FilePermission \Schadenskizze\classes\applet\pics\szenarios read)

in the Internet Explorer Java Console. I thought loading files is just forbidden if you load it from the Client...

Could someone help me ?

This should work:URL u = new URL(this.getCodeBase(),"../RelativePath/filename.txt");URLConnection uc = u.openConnection();InputStream in = uc.getInputStream();

you cannot read the directory content from an applet.

When the applet resides on a web server I hope you can understand why

directory listing is an unwanted feature.

When the applet resides on the local filesystem (opened from for example C:\temp) it can still not read a directory listing, as with applets opened from the

web you can access resources when you know the location, it is not possible to

list them.

It works when the applet is local....Too make listenenig a directory in a webserver possible i need to sign it right ?... this would be extremly important, since im working on this applet over 3 month .....

another option would be to create a config file which contains all paths to the files i would like to open.
