Hi Claas,
I understand that you have compiled your MATLAB function to a JAR file which you using in a Java driver application. But the dependency p-code file that you added during compilation in not being detected by your driver application
One way to check if the p-code file was successfully extracted is to check the MCR cache directory. For Windows OS, by default this directory will be [C:\Users\{username}\AppData\Local\Temp\{username}\mcrCache{mcrversion}]. If you have set the MCR_CACHE_ROOT environment variable, then the files would have been extracted in the directory pointed by that environment variable.
One possible reason for this issue is that starting MATLAB R2014a, you can't compile pure p-code file. If you compile p-code file, you also need to have the corresponding .m file in the same folder.

Rohit
