Getting java.security.AccessControlException

Question

Platform:
OS: Sun OS 5.7
Weblogic Server 5.1.0
Service Pack 5
I've weblogic installed at /home/hement/sw/weblogic.
I'm deploying a bean (Session bean), which is simply creating an instance of
another class "SecurityTest" and calling its method in which I'm creating a
new SecurityManager. This class is in /home/hement/ejb directory.
Now when I invoke this bean, using a weblogic.policy file with following
lines:
-------------weblogic.policy----------------------
grant {
permission java.security.AllPermission;
the bean works fine, and the new SecurityManager is created.
But, if the change the above weblogic.policy file to
-------------weblogic.policy----------------------
grant codeBase "file:/home/-" {
permission java.security.AllPermission;
grant codeBase "file:${java.home}/-" {
permission java.security.AllPermission;
grant {

Any idea, why is it behaving like this? Your comments will be appreciated.

Answer 1

Well, the reason of the error is:
netstat -o -n -a | findstr 1099
TCP    0.0.0.0:1099           0.0.0.0:0              LISTENING       2300This means the port 1099 is being used by any other Application.
