Question

在JNI_CreateJavaVM方法创建JVM时，我遇到了一个问题 “程序'[4616] VnptTokenCplusplus.exe：Native'退出了代码1（0x1）。”，有人可以为我解释一下吗？

#include <jni.h>
#pragma comment(lib,"jvm");

JNIEnv* Vnpt_JavaCreateVM();
void Vnpt_JavaInvokeClass(JNIEnv* env);

int main(){
    JNIEnv* env = 0;
    env = Vnpt_JavaCreateVM();
    Vnpt_JavaInvokeClass(env);

    getchar();
}
JNIEnv* Vnpt_JavaCreateVM() {
    jint res;   
    JavaVM* jvm;
    JNIEnv* env;
    JavaVMInitArgs args;
    JavaVMOption options[1];

    args.version = JNI_VERSION_1_2; //  JNI_VERSION_1_2 is interchangeable for this example
    args.nOptions = 1;
    options[0].optionString = "-Djava.class.path=.";
    args.options = options;
    args.ignoreUnrecognized = JNI_FALSE;
    res = JNI_CreateJavaVM(&jvm, (void **)&env, &args);
    if(res < 0)
    {
    }
    return env;
}
void Vnpt_JavaInvokeClass(JNIEnv* env) {
    jclass mainClass;
    jmethodID mainMethod;

    mainClass = env->FindClass( "com/vnpt/TestJDialog");
    mainMethod = env->GetMethodID(mainClass, "tokenNotify", "()V");
    env->CallVoidMethod(mainClass, mainMethod);
}

输出：

Answer 1

我遇到了同样的问题并做了两件事来解决它：

1-将jvm.dll所在的位置（应该位于程序文件\ java \ jsdk_ * \ bin \ server中）添加到Windows机器上的PATH环境变量中

2-尝试更改“-Djava.class.path =”。指向实际目录或.jar文件（为我工作）

JNI_CreateJavaVM退出代码-1？
