Signed Jar FilesIn a Java 2 environment, Cloudscape 3.5 can detect digital signatures on jar files. When attempting to load a class from a signed jar file stored in the database, Cloudscape will verify the signature's validity. NOTE: In Java 1.1 environments jar file signatures are ignored. NOTE: The Cloudscape class loader only validates the integrity of the signed jar file and that the certificate has not expired. Cloudscape cannot ascertain whether the validity/identity of declared signer is correct. To validate identity, use a Security Manager (i.e., an implementation of java.lang.SecurityManager). When loading classes from an application jar file in a Java 2 environment, Cloudscape behaves as follows:
NOTE: Cloudscape does not provide a security manager.
