Insert in scene object X3D & 3DS

Hi all guys.



I need a your help. While I am inexperienced. I'm studying just the JME.



I need to ask you a question?



You can insert objects into a scene with X3D and 3ds extension?



I saw a table with all the formats that supports JME, and there are these two.



My question is: How can I enter? Someone can post a sample code??
