multi-texture function & vertex normal questio

hi~
I want to put a water plane(4 point3f quadArray) with 2 water texture in the scene.And I want to set some vertex normals(I hope over 4) on it for shading. How to do that?
thank~

You can create vertex normals with the NormalGenerator utility class or by yourself. If you want or need to do it yourself, have a look at http://java.sys-con.com/read/48544.htm which has a section on vertex normals.

Multi-texturing is done through the use of multple texture units. You should master texture mapping a single texture and then multi-texturing.
