下列程式我用BCB寫了一段jni的程式,java呼叫GetProcessList(),然後回傳AnsiString變數abc,卻出現錯誤訊息說"Cannot convert AnsiString to jstring",abc的型態設成String也不行,請大家教教我,到底是什麼問題,謝謝大家!!    #include  #pragma hdrstop #include "Unit2.h" #include "tlhelp32.h" #include "psapi.h" #include #include "ProcessList.h" //------------------------------------------------------------------- #pragma package(smart_init) //------------------------------------------------------------------- JNIEXPORT jstring JNICALL Java_ProcessList_GetProcessList(JNIEnv *, jobject, jstring) { AnsiString abc; abc = "Hello!!"; return abc; }

Java_ProcessList_GetProcessList(JNIEnv *env, jobject jboj, jstring jstr){
  .....
  jboolean iscopy;
  char _destStr[80]="abc";
  return env->GetStringUTFChars(_destStr,&iscopy);
}
