Dear all!
I am using the Netscape signing tool to sign my applets. When starting
the applet I get the following error message:
java.lang.SecurityException: cannot verify signature block file
META-INF/ZIGBERT

This is my code:
public void init() {
try { jbInit();} catch(Exception e) { e.printStackTrace(); }
try {
PrivilegeManager.enablePrivilege("UniversalPropertyRead");
//hasPrivilege = true;
System.out.println("\tSuccess! Privilege is enabled.");
} catch (netscape.security.ForbiddenTargetException e) {
System.out.println("\tFailed! Permission to read system
properties denied by user.");
} catch (Exception e) {
System.out.println("\tFailed! Unknown exception while enabling
privilege.");
e.printStackTrace();
}
PrivilegeManager.enablePrivilege("UniversalFileRead");
PrivilegeManager.enablePrivilege("UniversalLinkAccess");
PrivilegeManager.enablePrivilege("UniversalConnect");
PrivilegeManager.enablePrivilege("UniversalPropertyWrite");
SystemAccess sys = new NetscapeSystemAccess();
SystemAccess.setSystemAccess(sys);
try {
System.out.println("Start OCF");
SmartCard.start();
.
.
.
The Self-signed certificate generated by "Netscape signing tool" is in
the signers list of Communicator!
What could cause this error then?
Greetings from Cologne!
