Applet Resource
Apu Kapadia
It seems that I cannot read a serialized object from a URL connection
that is not in the package...I'm confused.
I'm trying to download a DSAPrivateKey object from a file called
private.key that is accessible via a URL.
Thanks,
Apu
MY_PROGRAM.java
----------------
URL url = this.getClass().getResource("/private.key");
if (url==null)
{
url = new URL(getDocumentBase(), "private.key");
}
System.out.println("URL: " + url.toString());
InputStream is = url.openStream();
ObjectInputStream ois = new ObjectInputStream(is);
line 307: privateKey = (DSAPrivateKey) ois.readObject();
ois.close();
However I get the following exception:
java.security.AccessControlException: access denied
