Load model from InputStream

Hi Guys.

First of all, sorry for my bad english. I don`t speak english very well.

I have this problem:

I make a ResourceHandler’s class. I have this method:

[java]public InputStream getResource(String path);[/java]

When i can load a model, i call this method with the path of the model and it returns the InputStream.

Now, i can load the model from this InputStream.
I have reading this topic http://hub.jmonkeyengine.org/forum/topic/loading-a-jme-model-problems/ but I did’n succeed.

I tried this:

[java]Spatial mainMesh = (Spatial)BinaryImporter.getInstance().load(ResourceHandler.getResource(mainMeshPath));
rootNode.attachChild(mainMesh);[/java]

but it isn’t work.

What can i try?

Thanks a lot for your replies and sorry again for my horrible english.
