Verwenden von JNI zum Ausführen einer Java-JAR-Datei aus einem C ++ - Programm mithilfe von g ++ oder eclipse
Ich versuche anzurufen /ausführen ein JavaGlas aus a C ++ Programm.
Hier sind die Optionen, die ich bisher gefunden habe:
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
Ich würde gerne JNI verwenden, aber ich habe Probleme.
=======================
Hallo.cppIch habe eine einfache Hello.cpp-Klasse:
#include <iostream>
#include <jni.h>
using namespace std;
int main() {
cout << "Hello World" << endl; // prints Hello World
JavaVM *jvm; /* denotes a Java VM */
JNIEnv *env; /* pointer to native method interface */
JDK1_1InitArgs vm_args; /* JDK 1.1 VM initialization arguments */
vm_args.version = 0x00010001; /* New in 1.1.2: VM version */
/* Get the default initialization arguments and set the class
* path */
JNI_GetDefaultJavaVMInitArgs(&vm_args);
vm_args.classpath = "/home/FinishedJars/HelloWorld/hello2.jar";
/* load and initialize a Java VM, return a JNI interface
* pointer in env */
JNI_CreateJavaVM(&jvm, &env, &vm_args);
/* invoke the Main.test method using the JNI */
jclass cls = env->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;
}
=======================
KompilierenUnd wenn ich versuche, mit etwas zu kompilieren, wie:
g++ -I /usr/lib/jvm/jdk1.6.0_34-x86/include/ Hello.cpp
Hinweis: Ich habe "jni.h" in diesem Ordner gefunden, also habe ich es eingefügt. Ich gehe davon aus, dass dies der richtige Ort ist, aber ich bin nicht sicher
Ich bekomme eine Menge Fehler (siehe unten)
=======================

=======================
Mehr Informationen:Ich habe dies mit Eclipse versucht, indem ich ein ausführbares leeres gcc-Projekt erstellt habe, meinen Hallo-Welt-Code erstellt habe und es funktioniert.
Danach habe ich den JNI-Code hinzugefügt und den Quellcode wie folgt importiert:
Klicken Sie mit der rechten Maustaste auf project -> properties -> C / C ++ General -> Pfade und Symbole -> Includes -> GNU C ++ -> Add ->
Fügen Sie dann das Verzeichnis hinzu, das die Datei jni.h enthält
Wenn ich versuche, es auf diese Weise zu erstellen, erhalte ich in Eclipse genau dieselben Fehler.
Außerdem laufe ich auf Ubuntu 10 64bit ...
=======================
Kann jemand helfen?
Es könnte ein sehr einfaches Importproblem sein, aber ich bin mir nicht sicher
=======================
UPDATE 1Laufen:
g++ -I /usr/lib/jvm/jdk1.7.0_06/include/ -I /usr/lib/jvm/jdk1.7.0_06/include/linux/ Hello.cpp
Gibt mir:
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
=======================
UPDATE 2Anscheinend wurde JDK1_1InitArgs in JDK 6 entfernt, daher habe ich mit JDK 5 jni.h folgendermaßen kompiliert:
g++ -I /usr/lib/jvm/jdk1.5.0_22-x86/include/ -I /usr/lib/jvm/jdk1.5.0_22-x86/include/linux/ Hello.cpp
und es gibt mir:
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*)’
=======================
UPDATE 3Ich habe einige Nachforschungen angestellt und mögliche Lösungen sind:
Füge -L / usr / X11R6 / lib hinzu, oder wo immer sich die X11-Bibliotheken befinden, auf den Befehl g ++ ... hatte keine Auswirkung.Fügen Sie die Pfade von ibhpi.so und libjvm.so zum LD_LIBRARY_PATH hinzu (für mich ist es bei /usr/lib/jvm/jdk1.5.0_22-x86/jre/lib/i386/native_threads /) ... hatte keine AuswirkungFügen Sie libjava.so zum LD_LIBRARY_PATH hinzu auch (meins ist bei /usr/lib/jvm/jdk1.5.0_22-x86/jre/lib/i386 /) ... hatte keine AuswirkungDas Hinzufügen von jre / lib zum LD_LIBRARY_PATH hatte keine AuswirkungEiner meiner letzten Build-Befehle (funktioniert aber immer noch nicht)
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
ERROR:
Hello.cpp:23: undefined reference to `JNI_GetDefaultJavaVMInitArgs'
Hello.cpp:27: undefined reference to `JNI_CreateJavaVM'
Ich habe & env in (void **) & env geändert, was von ldav1s vorgeschlagen wurde, um den void star error zu beseitigen
=======================
UPDATE 4Ich glaube, das Problem ist, dass ich versuche, Bibliotheken zu laden, die nicht für mein System erstellt wurden? ...
Mein derzeitiger Befehl lautet:
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
und bekomme:
...

/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: cannot find -lhpi
/usr/bin/ld: cannot find -ljvm
...
=======================
UPDATE 5 / LÖSUNGHat eine Weile gedauert, aber das gibt mir die geringste Anzahl von Fehlern!
g++ -fPIC
-L/usr/lib/jvm/java-6-openjdk/jre/lib

Hello.cpp
Warnungen:
Hello.cpp: In function ‘int main()’:

Hinweis: Denken Sie vor dem Ausführen daran, die amd-Bibliotheken zu LD_LIBRARY_PATH hinzuzufügen:
$ 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
