How to get Credential from credentialSpec

Hi,

I’m working on a custom node in Java and in that node I’ll need to get an AccessToken from another node (Microsoft Authenticator).

I already have create my custom node and managed to a build it with two input ports (one for the BufferedDataTable and one for the credentials CredentialPortObject).

Here is where I’m stuck, in my execute function I can get the CredentialPortObject but I don’t know how to get the AccessToken (should be a JWToken stored as a password) from that object.

protected BufferedDataTable execute(PortObject inData, final ExecutionContext exec)

throws Exception {

/*

• The input data table to work with. The “inData” array will contain as many

• input tables as specified in the constructor. In this case it can only be one

• (see constructor).

*/

BufferedDataTable inputTable = (BufferedDataTable) inData[DATATABLE_PORT];

DataTableSpec spec = inputTable.getDataTableSpec();

// get the access token from the credential port
CredentialPortObject credentialPortObject  = (CredentialPortObject) inData[CREDENTIAL_PORT];
...
return new BufferedDataTable[] { out };
}

NB this AccessToken will be required both at configuration and execution time
