WSS4J - Read KeyStore from a non-file resource (such as database, etc.)

[Soactive Inc]

I am using WSS4J and am wondering how I can use the WSS4J API in conjunction with non-file resources such as a database. I know that there is a section of code in AbstractCrypto.java that says:

...

this.properties = properties;
        String location = this.properties.getProperty("org.apache.ws.security.crypto.merlin.file
");
        InputStream is = null;

        /**
         * Look for the keystore in classpaths
         */
        DiscoverResources disc = 
new DiscoverResources();
        disc.addClassLoader(JDKHooks.getJDKHooks().getThreadContextClassLoader());
        disc.addClassLoader(loader);
        ResourceIterator iterator = 
disc.findResources(location);
        if (iterator.hasNext()) {
            Resource resource = iterator.nextResource();
            is = resource.getResourceAsStream();
        }


        /**
         * If we don't find it, then look on the file system.
         */
        if (is == null
) {
            try {
                is = new FileInputStream(location);
            } catch
 (Exception e) {
                throw new CredentialException(3, "proxyNotFound", 
new Object[]{location});
            }


        }

....

Does this mean I can provide a non-file resource URL in the same ...file property? If so, how can I specify a database URL? Any ideas appreciated.

Thanks.
