It won't create a Java VM (JNI)

Question

My simple command line app:

int _tmain(int argc, _TCHAR* argv[])
{
 JavaVM *jvm;
 JNIEnv *env;
 JavaVMInitArgs vm_args;
 JavaVMOption options[1];
 options[0]         


        

Answer 1

In my experiance,

Cause

Maybe, JVM.DLL is located in below path.

C:\Program Files\Java\jdk1.6.0_xx\jre\bin\client\ (a)

and below folder contains many DLLs the JVM needs;

C:\Program Files\Java\jdk1.6.0_xx\jre\bin\ (b)

So, the JMV.DLL (that you dynamically linked) tries to search the all DLLs in its parent folder(b).

Solution

Don't copy JVM.DLL to the same folder in which your .exe is located!!!! Check you PATH system variable. It have to contain (a) and (b) paths. If so, maybe your .exe will be executed successfully.
