Senior senior sister apprentice you good brother in java calling c + + is there is a problem , a few days failed to solve , we help ah forget
I finished with eclipse cdt c + + to write the code and compile successfully generated a dll file , but when the call occurred the following error

  Exception in thread "main" java.lang.UnsatisfiedLinkError: com.easytoo.union.jni.SUNSONPwd.SUNSON_OpenCom(II)I
  	at com.easytoo.union.jni.SUNSONPwd.SUNSON_OpenCom(Native Method)
  	at com.easytoo.union.jni.SUNSONPwd.getPinPwd(SUNSONPwd.java:73)
  	at com.easytoo.union.impl.UnionPayDeviceImpl.getPinPwd(UnionPayDeviceImpl.java:210)
  	at com.easytoo.union.impl.UnionPayDeviceImpl.main(UnionPayDeviceImpl.java:215)
  

my c + + compiler uses the MinGW.
see this is probably the reason for the error could not find the corresponding method . Is how it happened , we hope to help it, have dragged on for a few days , the company gave pressure ah

missing dll correspondence should be invoked files , it is recommended to view it, you should put the corresponding dll files into a directory and similar java or put C: \ windows \ under system32.
