Security Exception in Web Start

Question

Hi,
I have an application that maps the users local directory to a JTree.
I have implemented a drag and drop interface to move files from the user file system to a remote directory that sits on my server. The application runs fine without web start.
On deplyoing with web start I get following exception when I try to copy a file from the local file system to the remote file system.
java.security.AccessControlException: access denied (java.io.FilePermission D:\706\WS_FTP.LOG read)
     at java.security.AccessControlContext.checkPermission(AccessControlContext.java:270)
My jnlp file has the security set to all permissions.
<security>
     <all-permissions/>     
</security>
All my jar files are signed.
The lines that causes the exception are below.
DataSource ds = null;
// getting the data from the file object f
try{
ds = new ByteArrayDataSource(f,null);
}catch (IOException ioe)
System.out.println("IOException creating data source for tranfer of file
ioe.printStackTrace();
DataHandler dh = new DataHandler(ds);
// call is a Call object.
call.setMethodName(methodName);
My understanding of web start is that if I have the "all permissions" set and the jar files signed, I should have unrestricted access to the users file system. However I am getting an error.
That about sums up my problems.
I am absolutely lost and am eagerly awaiting some replies/suggestions/clues.
Thanks
Shahid

I have this problem too. For me I have 3 jars but not the same key signed.
When start app it ask user only one key add method in other class which not the same key throw exception
java.security.AccessControlException: access denied(java.io.FilePermission C:\file.txt read)
