Authentication failed for user: null

Question

I have an API "Vignette Collab" that is running on an Apache stack with Java, I inherited a legacy codebase and need to find where this error is coming from apparently the last developer built a feature that wasn't working and that's where the error is, but no more info. It is using the Drupal webservice module and the code sending the call looks like this

 $node = $variables['node'];
 $service = wsclient_service_load('collab_folders');

   if($node->field_oid1):
    $param1 = $node->field_oid1['und'][0]['value'];
    $params1 = array('user'=>'myUser','password'=>'myPass','oid'=>$param1);
    $results1 = $service->getChildren($params1);
    $variables['collabresults1'] = $results1;//

Any idea as to where I can begin looking for this error or what it may mean?

The full stack trace is here:::

Answer 1

The problem appears to be with this line: $results1 = $service->getChildren($params1);. The UnsupportedOperationException belongs to the Java Collections framework and means that you are trying to perform some operation on the array $params2 that the java api doesn't support. The first place I would look is at the version of java you are running and the version of java required by the Vignette Collab api. It sounds to me that perhaps a later version of java is required than you are currently using.

You may also want to dig into the api to see what getChildren() does, and make sure you are passing in the correct parameter value.
