Re: [kura-dev] another question
Hi Scott,

That’s strange. Could you try the following snippet?

    String getPassword() {

        final Object pass = this.properties.get(PASSWORD);

        Password decryptedPassword = null;

        String password = null;

        if (this.properties.containsKey(PASSWORD) && (pass != null)) {

            try {

                decryptedPassword = new Password(this.cryptoService.decryptAes(pass.toString().toCharArray()));

                password = new String(decryptedPassword.getPassword());

            } catch (final KuraException e) {

                s_logger.error(ThrowableUtil.stackTraceAsString(e));

            }

        }

        return password;

    }


This depends on CryptoService to decrypt the AES encoded password field in your Metatype attribute definition.

Hope it helps.

Thanks and Regards,

Hi David,

Yes, the MqttDataTransport class is where I got this line of code:

Password password = (Password) properties.get("password");   line 716

But when I try to do the same thing in my own code, the same throws an exception because the type of the "password" value is a String rather than Password, and has the encoded value as described below.

I'm at a loss as to why my properties contains a String rather than a Password.   I'm using the exact same AD definition that's used in the MqttDataTransport metatype.

Thanksinadvance for any info,

Scott

Hi Scott,

Please see the example of how MqttDataTransport is using the Password class [1]. Just search for “Password” and you can find what you need.


Thanks,

I'm creating a ConfigurableService and I would like to put a password into the web UI.   I looked at the metatype for the MqttDataTransport...which has a password used to connect to the cloud service...and the acd for that field looks like this:

       <AD id="password"  
           name="password"
           type="Password"
           cardinality="0"
           required="false"
           default="password"
           description="Password to be used when connecting to the MQTT broker."/>


And the code that handles this configuration looks like this:

Password password = (Password) properties.get("password");

The Password class is:  org.eclipse.kura.configuration.Password

Fair enough.   But when I put the exact same AD into my metatype, and try to use the property the following line throws an exception:

Password password = (Password) properties.get("password");

The type of the password property is not Password, but rather it's a String and what looks like a uuencoded value for the String...e.g.:  1LnomW8pXWdXQLVTfyMQ1Q==

Obviously there is something I'm doing differently to not get a Password instance via the Kura Config Admin.   Any idea what that is?

Thanksinadvance for any thoughts,

Scott
