Java apps has by default 64 MB to run, sometimes a java app needs to store on memory more than that value. In this case you loaded toooooooooooooooooooooooooooo huge textures. The normal resolutions are 256x256 not 2048x2048, try changing the size of your textures. They shouldnt really affect the final result.

Do you really need to have a huge texture or it may be better to small one that is fit to the object face.

each part is a jpg file of 2048x2048 because  i want a good level of details like in the following screen

How can I have this level of details in JPCT without huge textures?

thanks

Just start the app with -Xmx256m (or whatever value you prefer) to increase the maximum heap size.
