我需要一个 Java 应用程序来调用非托管 C++。我将 MSVCR90.dll 从 Visual Studio 2008 redist 路径手动复制到 vmware 的 Windows Server Datacenter。
这是我得到的错误:
Java 运行时环境检测到一个致命错误:
EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x73b4ae7a, pid=1108, tid=2272 JRE version: 6.0_38-b05 Java VM: Java HotSpot(TM) Client VM (20.13-b02 mixed mode, sharing windows-x86 ) Problematic frame: C [MSVCR90.dll+0x3ae7a] An error report file with more information is saved as: ...\hs_err_pid1108.log If you would like to submit a bug report, please visit: http://java.sun.com/webapps/bugreport/crash.jsp The crash happened outside the Java Virtual Machine in native code. See problematic frame for where to report the bug.
这是 C++ 代码:
#include "stdafx.h"
#include <stdio.h>
#include "CCCheckString.h"
#include <vector>
#include <String>
using namespace std;
#include "jobHandler.h"
JNIEXPORT jbolean JNICALL Java_CCCheckString_Login
(JNIEnv *env, jobject object, jstring host, jstring UserName, jstring Domain, jstring Password)
{
bool result;
jobHandler *handler = new jobHandler();
const char *hostStr = (env)->GetStringUTFChars(host, NULL);
string hostS(hostStr);
const char *UserNameStr = (env)->GetStringUTFChars(UserName, NULL);
string UserNameS(UserNameStr);
const char *DomainStr = (env)->GetStringUTFChars(Domain, NULL);
string DomainS(DomainStr);
const char *PasswordStr = (env)->GetStringUTFChars(Password, NULL);
string PasswordS(PasswordStr);
//if comment this line everthing is okey
**result = handler->Login(hostS,UserNameS,DomainS,PasswordS);**
(env)->ReleaseStringUTFChars(host, NULL);
(env)->ReleaseStringUTFChars(UserName, NULL);
(env)->ReleaseStringUTFChars(Domain, NULL);
(env)->ReleaseStringUTFChars(Password, NULL);
delete handler;
return result;
}
下面是Java中的处理代码:
CCCheckString ccCheckString = new CCCheckString();
result=ccCheckString.Login("xxx", "xxx", "xx", "xxx");
我该如何解决这个错误?
