title: JNI Cannot compile dynamic library
body: <p>I'm creating an c++ dynamic library to use in an native class in java
  I have generated an header file for that class using javah.exe and have created the c interface class for it,but when I try to comile the file or build the project I get the following error</p>

  <p>some data types such as jlong,int64,int32 have not been defined
  I'm using netbeans to compile this library
  I'm stuck at this point
  plzz help anyone?</p>
