没有指定类

Question

我一直遵循netbeans中的JNI教程，我遇到了以下问题。

请帮我解决这些问题

C:UsersavijapurDocumentsNetBeansProjectsHelloWorld>"C:Program FilesJavajdk1.8.0_101binjavah.exe" -o HelloWorldNative.h -jni -classpath  "C:UsersavijapurDocumentsNetBeansProjectsHelloWorldbuildclasseshelloworld"HelloWorld.main"
Error: no classes specified
C:UsersavijapurDocumentsNetBeansProjectsHelloWorld>

Answer 1

您应该在命令行中指定class，如

javah.exe -o HelloWorldNative.h -jni -classpath  "C:UsersavijapurDocumentsNetBeansProjectsHelloWorldbuildclasses" helloworld.HelloWorld
