Hi Benoît, Looking at the style builder classes, it does not seem to be possible, as it does not expose a method that creates a stroke from an Expression. However you can get at the underlying style factory (getStyleFactory()), and should be able to manually build up the symbolizer, creating the stroke with a property expression. The downside being that it will take 3 or 4 lines of code to build up the symbolizer manually, instead of calling a single method on the builder.
