Examples of java.security.CodeSource

java.security.CodeSource

This class extends the concept of a codebase to encapsulate not only the location (URL) but also the certificate chains that were used to verify signed code originating from that location. @version 1.41, 11/17/05 @author Li Gong @author Roland Schemers

            ProtectionDomain pd = (ProtectionDomain)pdCache.get(bytecode.codebase);
            if (pd == null) {
                try {
                    URL url = urlFactory.getCodeBase(bytecode.codebase);
                    
                    CodeSource source = new CodeSource(url, (Certificate[])null);
                    pd = new ProtectionDomain(source, null, this, null);
                    pdCache.put(bytecode.codebase, pd);
