The specified module could not be found

Dear all, I have a problem similar to #92, but from the other side. I am trying to load JPL from Prolog. I should have set properly all the environmental variables, I am using the daily binaries. If I call Prolog from Java, everything works fine. If I try to load JPL library from Prolog using the command [library(jpl)]. I get

ERROR: c:/program files/swipl/library/jpl.pl:5428:

I have also called win_process_modules/1, which returns: c:/program files/swipl/bin/swipl.exe, c:/windows/system32/ntdll.dll, c:/windows/system32/kernel32.dll, c:/windows/system32/kernelbase.dll, c:/windows/system32/msvcrt.dll, c:/program files/swipl/bin/libswipl.dll, c:/windows/system32/advapi32.dll, c:/windows/system32/sechost.dll, c:/windows/system32/rpcrt4.dll, c:/windows/system32/psapi.dll, c:/windows/system32/shell32.dll, c:/windows/system32/msvcp_win.dll, c:/windows/system32/ucrtbase.dll, c:/program files/swipl/bin/libgcc_s_seh-1.dll, c:/program files/swipl/bin/libwinpthread-1.dll, c:/windows/system32/user32.dll, c:/windows/system32/win32u.dll, c:/windows/system32/gdi32.dll, c:/windows/system32/gdi32full.dll, c:/windows/system32/ws2_32.dll, c:/windows/system32/winmm.dll, c:/program files/swipl/bin/libgmp-10.dll, c:/program files/swipl/bin/zlib1.dll, c:/windows/system32/imm32.dll, c:/windows/system32/windows.storage.dll, c:/windows/system32/combase.dll, c:/windows/system32/wldp.dll, c:/windows/system32/shcore.dll, c:/windows/system32/shlwapi.dll, c:/windows/system32/profapi.dll

Here I cannot see the jvm.dll, I don't know if this could be the problem. However, JAVA_HOME is set to C:\Program Files\AdoptOpenJDK\jre-8.0.292.10-hotspot and in PATH I have both %JAVA_HOME%\bin and %JAVA_HOME%\bin\server.

Any idea to solve the problem? Thank you

Hard to say. jpl and the jvm dlls are not in the process modules because it cannot load them. If it works the other way around, use win_process_modules/1 in that config and see whether you have missed some directory or you have a directory in %PATH% that should not be there and it gets a conflicting file from some other location.

I have cleaned up my JDKs and environment variables. Now, magically, it works :) Probably there were some conflicting files as you suggested.

Many thanks
