link 32 bits native language dll on 64 bits os windows

I'm trying to use a java program on 64 bits virtual machine windows 7 to process videos. This java program uses a 32 bits dll. According to this post, I installed a 32 bits jvm and according to this one, I put the dll in C:\WINDOWS\SysWOW64 directory.

I run the program in the command prompt by specifyng the full path C:\Program Files (x86)\Java\jre7\bin\java.exe of the executable. The java program runs normally, but when it comes to use the functionality provided by the dll, I receive the error message java.lang.UnsatisfiedLinkError.

Thanks for any advice

Paul

UnsatisfiedLinkError means that Java could not find the DLL.

Make sure that the directory that contains the DLL is in the java.library.path. You can set this path by specifying it as a system property on the command line, using the -D switch, when you start your program. For example:

java -Djava.library.path=C:\WINDOWS\SysWOW64 com.mypackage.MyMainClass
