Load a library that calls functions from a dependency from java

[K-Full]

I want to call the dll output by unmanagedexportts from JNA.
However, all dlls that are dependent on dll must be placed in the same folder as JRE.
I think it would be nice if there was a way to go to load dll in the same folder as dll in a folder different from JRE. I would like you to tell me if there is something else in a different way.

It shouldn't be related for DllExport at all, because it only adds records into EXPORT_DIRECTORY (read more about PE32/PE32+).
That is, the final dynamic-link libraries(DLL) should contains the addresses of exported functions/variables as for your example from #25

If you have problem with paths:

For example, the windows platform (WinAPI) provides LoadLibrary functions for work with dynamic libraries (DLL).

https://msdn.microsoft.com/en-us/library/windows/desktop/ms684179.aspx

HMODULE WINAPI LoadLibraryEx(
  _In_       LPCTSTR lpFileName,
  _Reserved_ HANDLE  hFile,
  _In_       DWORD   dwFlags
);

You can try to use flag 0x00000200 (LOAD_LIBRARY_SEARCH_APPLICATION_DIR) - If this value is used, the application's installation directory is searched for the DLL and its dependencies.
or 0x00000400 via AddDllDirectory etc.

e.g. my implementation for .NET uses 0x00000008 (LOAD_WITH_ALTERED_SEARCH_PATH)

The JNA uses this logic: https://github.com/java-native-access/jna/blob/master/src/com/sun/jna/NativeLibrary.java

so you can also try to use:

public static final void addSearchPath(String libraryName, String path)

+ other specific way for JNA, and any own implementation of course.

By the way:

java.lang.Error: Invalid memory access

the problem can be for different architectures (x64/x86 ...). I don't remember specific error for java but it looks like incorrect access in memory by reading of incorrect addresses etc.
