如何通过vc ++ 2008调用Java类并传递/返回值 [英] How to call java class and pass/return values through vc++ 2008

问题描述

当我尝试代码时，我已经尝试过如何使用JNI通过AJalilqarshi从C调用Java函数"，出现以下错误:

 1> VC_JAVA.obj:警告LNK4248:"_ jmethodID"的未解析的typeref令牌(0100000F)；图像可能无法运行
1> VC_JAVA.obj:错误LNK2028:未解析的令牌(0A000011)外部" C长__stdcall JNI_CreateJavaVM(struct JavaVM_ * *，void * *，void *)"(?JNI_CreateJavaVM @@ $$ J212YGJPAPAUJavaVM _ @@ PAPAXPAX @ Z)在函数"struct JNIEnv_ * __cdecl create_vm(struct JavaVM_ * *)"中引用(?create_vm @@ $$ FYAPAUJNIEnv _ @@ PAPAUJavaVM _ @@@ Z)

1> VC_JAVA-3个错误，1个警告

当我使用jdk1.6.0_23版本时.我需要将jdk 1.6更改为此版本吗?
谢谢

解决方案

I have already tried "How to Call Java Functions from C Using JNI By ajalilqarshi" when i tried the code i got the following errors:

1>VC_JAVA.obj : warning LNK4248: unresolved typeref token (0100000F) for '_jmethodID'; image may not run

While i am using jdk1.6.0_23 version. Do i need to change jdk 1.6 to this version?
Thank you
