jni调用dll，java.lang.UnsatisfiedLinkError错误

[pangzhuzhu]

libHelloWorld.dll是xp上VC6生成的
之后拷贝到win7上面helloworld目录下同源代码一起。

java HelloWorld报错，java -Djava.library.path='.' HelloWorld仍旧报错。

E:\helloworld>ls
HelloWorld.class HelloWorld.h HelloWorld.java libHelloWorld.dll

E:\helloworld>java -Djava.library.path='.' HelloWorld
Exception in thread "main" java.lang.UnsatisfiedLinkError: no HelloWorld in java
.library.path
at java.lang.ClassLoader.loadLibrary(Unknown Source)
at java.lang.Runtime.loadLibrary0(Unknown Source)
at java.lang.System.loadLibrary(Unknown Source)
at HelloWorld.<clinit>(HelloWorld.java:4)

谢谢帮助！
