Configurable joint around 2 axis

Hi every one, I would like to rotate a configurable joint around 2 axis. I actually do this :

var configurableJoint = GetComponent(ConfigurableJoint); configurableJoint.targetRotation= Quaternion.AngleAxis( angle, Vector3.right );

The "Axis" of my joint is : X : 0 - Y : 1 - Z : 0.

So the object rotatate around Y with the "angle' variable.

Now I want to rotate it around Y and Z simultaneously. The "Axis" of my joint become : X : 0 - Y : 1 - Z : 1. But I don't understand how to script it (the angle can be different around Y and Z)

Thanks for help
