When you try to open the URL for the first time (or click the "Execute" button in the docs) the browser will ask you for your username and password:

## Check the username

Here's a more complete example.

Use a dependency to check if the username and password are correct.

        if (logger.isDebugEnabled()) {

        //   required check
        final Object urlObj = dataMap.get(fessConfig.getIndexFieldUrl());
        if (urlObj == null) {
            throw new DataStoreException("url is null. dataMap=" + dataMap);
        }

        assertTrue(UriTypeValidator.check(protocols, values));

        protocols = new String[] { "http:" };
