UnsatisfiedLinkError

[Monoj Roy]

Hi I am getting the following error in my RAD 7 console

java.lang.UnsatisfiedLinkError: pdosapi (JVMPORT015E Unable to resolve DLL references - a prerequisite DLL may be missing)

I have put the pdosapi.dll in the PATH variable ..Anything more need to configure..?Please help and let me know if there is any special file where from RAD 7 reads the .dll file ..

Hi,
I am unaware of Rad 7 but from your post, it seems that you are doing it the wrong way. Because you dont put the dll in the path variable, its not going to help. instead put the dll in the application installation directory.


Hope this helps

Don't know for sure if it helps, but have you tried registering the dll?
Or as a last resort have you tried moving the dll to System32 folder of Win OS?

UnsatisfiedLinkError means that Java cannot find a native library (a DLL on Windows) that it needs. Try starting your program by using the -Djava.library.path=... option:

java -Djava.library.path=dir that contains the DLL com.mycompany.mypackage.MyMainClass

You don't need to register JNI DLLs with Windows. Registering DLLs is a COM thing, I believe.

Be very careful about moving DLLs to System32. You can get very confused if you ever forget to remove it again. I advise against "trying" this.

Thanks a lot each of you for helping my problem .

I solved it .

The problem was I have not included another .dll file that was reference by pdosapi.dll which is my application specific ,Now I have put all of them in a folder and added them to PATH and it is working .

Once again Thanks everybody .
