Hi,<br><br> I think it is possibile using the swig's director feature: Calling back non c/c++ from c/c++ code.<br><br>Basically you have to develop your driver as a C++ class declared in a swig interface file (.i) declaring virtual functions that have to implements the features of your driver. This driver should be viewed as an abstract driver.<br>
The "concrete" driver is implemented by a swig generated class that calls you java code implementing the virtual functions you declared in you ".i file".<br><br>Regards,<br>Stefano<br><br><div style="margin:0 0 8px 0">

</div>I'm not sure if you can call Java code with SWIG. Perhaps, but that's perhaps<br>
more a question for a SWIG mailing list. I don't see how the code of the GDAL<br>
SWIG bindings could help you since you will use a dedicated API for your Java<br>
library.<br>
