Can't load serialized object Android

[cocojack]

Hello, im working on some tutorials to get into JPCT-AE.
At the moment i'm trying to load a texture of an airplane into my android app.

I've downloaded a model of an airplane and serialized it with jBrush v0.3.


my code:

         ZipInputStream serStream = new ZipInputStream(masterContext.getResources().openRawResource(R.raw.dassault_mirage));
         try{serStream.getNextEntry();}
         catch(IOException e)
         {throw new RuntimeException(e);}
         airplane = Loader.loadSerializedObject(serStream);
         airplane.setTexture("texture");


on start, this code part gets a runtime exception:
java.lang.RuntimeException: [ 1364121233198 ] - ERROR: Can't deserialize object: length=256; regionStart=-1; regionLength=257

airplane = Loader.loadSerializedObject(serStream);

i dont know what I did wrong this time

Looks like as if something is wrong with your input stream. Can you post the full stack trace?

could it be that the files doesnt load correctly to my android device?

It works now, may anyone can explain what is the difference between those:

terrain = Loader.loadSerializedObject(masterContext.getResources().openRawResource(R.raw.dassault_mirage));
terrain.setTexture("texture");

forgot to mention that I use this document to get in jpct-ae : http://www.jpct.net/forum2/index.php?topic=2667.0
