使用JNI从C ++程序执行java jar，使用g ++或eclipse

我正在尝试从 C ++程序调用/ 执行 java jar 。

以下是我到目前为止找到的选项： 

Use JNI Use Jace Use JunC++ion Use execl("java", "java", "-jar", "myprog.jar", NULL); Use execlp("java", "java", "-jar", "myprog.jar", (char *)0); Use system("java filename.jar"); Use popen("java -jar test.jar text1 text2", "r"); Use CreateProcess(...); Use JNA

我想使用JNI，但是我遇到了问题。

========================

HELLO.CPP

我有一个简单的Hello.cpp类： 

 #include  #include  using namespace std; int main() { cout << "Hello World" <FindClass("Main"); jmethodID mid = env->GetStaticMethodID(cls, "test", "(I)V"); env->CallStaticVoidMethod(cls, mid, 100); /* We could have created an Object and called methods on it instead */ /* We are done. */ jvm->DestroyJavaVM(); return 0; }

========================

编

当我尝试使用类似的东西进行编译时： 

 g++ -I /usr/lib/jvm/jdk1.6.0_34-x86/include/ Hello.cpp

注意：我在该文件夹中找到了“jni.h”，因此我将其包含在内。 我认为那是正确的选择，但我不确定

我收到了很多错误（见下文）

========================

错误

我从jni.h得到了一百万个错误，好像它正在尝试编译jni.h：

========================

更多信息：

我用eclipse尝试了这个，通过创建一个可执行的空gcc项目，创建我的hello world代码，它运行正常。

之后，我添加了jni代码，并通过以下方式导入了源代码：

右键单击项目 – >属性 – > C / C ++常规 – >路径和符号 – >包含 – > GNU C ++ – >添加 – >

然后添加包含jni.h的目录

当我尝试以这种方式构建它时，在eclipse中，我得到完全相同的错误。

另外，我正在使用Ubuntu 10 64bit …

========================

有人可以帮忙吗？

这可能是一个非常简单的导入问题，但我不确定

========================

更新1

运行：

g++ -I /usr/lib/jvm/jdk1.7.0_06/include/ -I /usr/lib/jvm/jdk1.7.0_06/include/linux/ Hello.cpp

给我： 

 Hello.cpp: In function 'int main()': Hello.cpp:19: error: 'JDK1_1InitArgs' was not declared in this scope Hello.cpp:19: error: expected ';' before 'vm_args' Hello.cpp:20: error: 'vm_args' was not declared in this scope

========================

更新2

显然在JDK 6中删除了JDK1_1InitArgs，所以我使用JDK 5 jni.h编译，如下所示：

g++ -I /usr/lib/jvm/jdk1.5.0_22-x86/include/ -I /usr/lib/jvm/jdk1.5.0_22-x86/include/linux/ Hello.cpp

它给了我： 

 Hello.cpp: In function 'int main()': Hello.cpp:24: warning: deprecated conversion from string constant to 'char*' Hello.cpp:27: error: invalid conversion from 'JNIEnv**' to 'void**' Hello.cpp:27: error: initializing argument 2 of 'jint JNI_CreateJavaVM(JavaVM**, void**, void*)'

========================

更新3

我一直在做一些研究，可能的解决方案是：

  1. 在-g ++命令中添加-L / usr / X11R6 / lib ，或X11库所在的地方……都没有效果。
  2. 将ibhpi.so和libjvm.so的路径添加到LD_LIBRARY_PATH （对我来说，它位于/usr/lib/jvm/jdk1.5.0_22-x86/jre/lib/i386/native_threads /）…没有效果
  3. 将libjava.so添加到LD_LIBRARY_PATH （我的位于/usr/lib/jvm/jdk1.5.0_22-x86/jre/lib/i386 /）…没有效果
  4. 将jre / lib添加到LD_LIBRARY_PATH …无效

我的最终构建命令之一（但仍然无法工作） 

 g++ -g -I /usr/lib/jvm/jdk1.5.0_22-x86/include/ -I /usr/lib/jvm/jdk1.5.0_22-x86/include/linux/ -L/usr/lib/jvm/jdk1.5.0_22-x86/jre/lib/i386/ Hello.cpp

错误： 

 Hello.cpp:23: undefined reference to `JNI_GetDefaultJavaVMInitArgs' Hello.cpp:27: undefined reference to `JNI_CreateJavaVM'

我改变了env到（void **）＆env，由ldav1s建议摆脱虚空星的错误

========================

更新4

我相信问题是我正在尝试加载不是为我的系统构建的库？…

我目前的命令是： 

 g++ -L/usr/lib/jvm/jdk1.5.0_22-x86/lib -L/usr/lib/jvm/jdk1.5.0_22-x86/jre/lib -L/usr/lib/jvm/jdk1.5.0_22-x86/jre/lib/i386 -ljava -L/usr/lib/jvm/jdk1.5.0_22-x86/jre/lib/i386/native_threads -lhpi -L/usr/lib/jvm/jdk1.5.0_22-x86/jre/lib/i386/server -ljvm -I /usr/lib/jvm/jdk1.5.0_22-x86/include/ -I /usr/lib/jvm/jdk1.5.0_22-x86/include/linux/ Hello.cpp

并得到： 

 ... /usr/bin/ld: skipping incompatible /usr/lib/jvm/jdk1.5.0_22-x86/jre/lib/i386/libjava.so when searching for -ljava /usr/bin/ld: skipping incompatible /usr/lib/jvm/jdk1.5.0_22-x86/jre/lib/i386/native_threads/libhpi.so when searching for -lhpi /usr/bin/ld: skipping incompatible /usr/lib/jvm/jdk1.5.0_22-x86/jre/lib/i386/server/libjvm.so when searching for -ljvm /usr/bin/ld: cannot find -ljava /usr/bin/ld: cannot find -lhpi /usr/bin/ld: cannot find -ljvm ...

========================

更新5 /解决方案

花了我一会儿，但这给了我最少的错误！ 

 g++ -fPIC -L/usr/lib/jvm/java-6-openjdk/jre/lib -L/usr/lib/jvm/java-6-openjdk/jre/lib/amd64 -ljava -lverify -L/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/native_threads -lhpi -L/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server -ljvm -I /usr/lib/jvm/jdk1.5.0_22-x86/include/ -I /usr/lib/jvm/jdk1.5.0_22-x86/include/linux/ Hello.cpp

警告： 

 Hello.cpp: In function 'int main()': Hello.cpp:24: warning: deprecated conversion from string constant to 'char*

注意：在运行之前记得将amd库添加到LD_LIBRARY_PATH： 

 $ export LD_LIBRARY_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/amd64:$LD_LIBRARY_PATH $ export LD_LIBRARY_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/native_threads:$LD_LIBRARY_PATH $ export LD_LIBRARY_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server:$LD_LIBRARY_PATH $ export LD_LIBRARY_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib:$LD_LIBRARY_PATH

谢谢！

通常你必须在Linux上添加某种特定于平台的目录： 

 g++ -I /usr/lib/jvm/jdk1.6.0_34-x86/include/ -I /usr/lib/jvm/jdk1.6.0_34-x86/include/linux Hello.cpp

因为那里设置了一些宏（如JNICALL ）。 希望这将修复jni.h错误级联。

编辑：仍然卡住？ 尝试： 

 JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args);

它至少会超越编译问题。 我不知道它是否有效 ，因为我之前没有尝试过。
