Using Visibroker in Signed Applet - access denied (java.net.SocketPermissio
Hello,
I have an signed applet which using visibroker to connect to the server.
I'm getting this exception:
org.omg.CORBA.COMM_FAILURE: java.security.AccessControlException: access
denied (java.net.SocketPermission x.x.x.x:51175 connect,resolve) minor
code: 0 completed: No
The IP address listed in the stack trace is the same as the URL of the HTML
page containing the applet. So how do I get a security exception? And even
so, I do not understand how I have this error when my applet is signed.
The vbjorb.jar file is located on the client PC. My applet is located on
the server.
I have tried wrapping the call that fails with:
AccessController.doPrivileged(new PrivilegedAction() {
public Object run() {
but that doesn't work. I signed the vbjorb.jar but that didn't work. I
configured the java.policy to give the vbjbroker.jar file AllPermission but
that doesn't work. However, if in the java.policy file I put:
grant {
permission java.security.AllPermission;
};
it does work. So I know it's a problem related to security permissions.
I'm just not sure how to solve it. The next thing I'm going to try is to
combine my 2 jars (vbjorb.jar & applet.jar) into a single signed jar. If
this doesn't work then I will be completely out of ideas.
Here are the technical version details:
JDK 1.4.2_06
Visibroker 4.5
Windows XP
MS Internet Explorer 6
A few more odd things: This works with Windows 2000 at the client's site,
but not XP. The client mailed us one of their XP PCs and it works at our
place. I assume this is because it's deployed differently at the client
site but I cannot explain how it can work with Windows 2000 and not XP at
their site.
If anyone has any ideas I'd be very grateful. Thank you very much.
Michael
