JNI - ERREUR EXECUTION

**troumar** · 09/12/2017, 15h08

Bonjour a tous,

je souhaite beneficier de votre aide pour m aider a resoudre une erreur que je rencontre lors de l execution de mon programme JNI. En effet jai ecrit des fonctions en C permettant de creer une queue ipc, ensuite recuperer son identifiant et le stocker dans une memoire partagee. L objectif est de permettre aux autres programmes de pouvoir recuperer l identifinat de la queue de la memoire partagee afin de lire ou ecrire un message.
Ci-dessous les differents elements et l erreur rencontree :

1. La classe java

Merci de m aider a analyser ce qui ne va pas avec mon code en C.
Apres une petite investigation j ai l impression que le soucis doit venir de cette ligne de mon programme en C :

Code :

	 *((ST_SC_MsgQ*)caShm) = data;

Merci d avance pour votre aide.

Salut,

Tu as modifié le code C avec ton copier/coller.

Malgré que l'instruction *((ST_SC_MsgQ*)caShm) = data; me paraisse louche (ps: je n'aurais pas effectué le cast à gauche, mais à droite de l'opérateur =), je pense que l'erreur peut provenir d'ailleurs car dans ta stacktrace je vois l'exception suivante :

Internal exceptions (2 events):
Event: 0,452 Thread 0x00007f57a0008800 Exception <a 'java/lang/NoSuchMethodError': Method sun.misc.Unsafe.defineClass(Ljava/lang/String;[BII)Ljava/lang/Class; name or signature does not match> (0x00000000d8b07ca8) thrown at [/HUDSON3/workspace/8-2-build-linux-amd64/jdk8u144/9417/hotspot/src/sh
Event: 0,452 Thread 0x00007f57a0008800 Exception <a 'java/lang/NoSuchMethodError': Method sun.misc.Unsafe.prefetchRead(Ljava/lang/Object;J)V name or signature does not match> (0x00000000d8b07f90) thrown at [/HUDSON3/workspace/8-2-build-linux-amd64/jdk8u144/9417/hotspot/src/share/vm/prims/jni.c

Je pense donc que l'erreur doit peut-être provenir des fonctions (*env)->. par exemple je vois ceci dans ton code :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1

3
caMsgQID = ((char ) iMsgQID);
 
return ((*env)->NewStringUTF( env,caMsgQID));

caMsgQID est un char*, iMsgQID est un int, tu essayes de caster avec un char déjà le compilateur aurait du refuser la compilation (sauf erreur de copier/coller ?). Aussi NewStringUTF prend en paramètre un const char* et s'attend à '\0' pour la fin de chaine de caractère je pense, en effectuant le cast tu n'as pas cette information.
