Answer 1

If you are using eclipse: append -classpath PATH_OF_PACKAGE_TOP into javah CLASSNAME

Example:javah -classpath . com.byf.test.JNI

my tree : `
.
├── com
│   └── byf
│       └── test
│           └── JNI.java
└── libcall.so`


result:`
    byf@byf-Ubuntu:~/code/workspace_eclipse_java/JAVA_YF/src$ javah -classpath . com.byf.test.JNI
    byf@byf-Ubuntu:~/code/workspace_eclipse_java/JAVA_YF/src$ ls
    com  com_byf_test_JNI.h  libcall.so
    byf@byf-Ubuntu:~/code/workspace_eclipse_java/JAVA_YF/src$ cat com_byf_test_JNI.h 
    /* DO NOT EDIT THIS FILE - it is machine generated */
    #include 
    /* Header for class com_byf_test_JNI */

    #ifndef _Included_com_byf_test_JNI
    #define _Included_com_byf_test_JNI
    #ifdef __cplusplus
    extern "C" {
    #endif
    /*
     * Class:     com_byf_test_JNI
     * Method:    add
     * Signature: (II)I
     */
    JNIEXPORT jint JNICALL Java_com_byf_test_JNI_add
      (JNIEnv *, jclass, jint, jint);

    #ifdef __cplusplus
    }
    #endif
    #endif
