Javah error: could not find class file for 'com.ntv.ndkjni'

2717046

Hi,

My project directory  : C:\ndkJNI

My java file directory : C:\ndkJNI\src\com\ntv\ndkjni

My package name    : com.ntv.ndkjni

1 ) I entry command prompt at C:\ndkJNI\src\com\ntv\ndkjni

2 ) Javac test.java and create test.class succesfully. test.class is in  C:\ndkJNI\src\com\ntv\ndkjni folder.

3 ) Later I used Javah, try below javah variously

     a)  javah -classpath C:\ndkJNI\src\com\ntv\ndkjni test

     b)  javah -classpath C:\ndkJNI\src\com\ntv\ndkjni.test

     x) javah -classpath C:\ndkJNI\src\com\ntv\ndkjni com.ntv.ndkjni.test

     y) javah -classpath C:\ndkJNI\src\com\ntv\ndkjni com.ntv.ndkjni test

     c)  javah -classpath C:\ndkJNI\src\com\ntv\ndkjni com.ntv.ndkjni.test

     d)  javah  com.ntv.ndkjni.test

     e) javah  com.ntv.ndkjni test

     f) javah  com.ntv.ndkjni test.class-> (error: exception in a thread illegal argument exception)

    

I am searching  for 5 day. I couldnt find solution. I try different computer. I tried ubuntu and win8, the error still with me.

Thats interesting when I delete the package com.ntv.ndkjni; from java file,  then create class file again with javac then javah can create header file succesfully.

Please help me.

package com.ntv.ndkjni;

public class test {

  System.loadLibrary("hello");

  }

    public static native int toplama(int sayi1,int sayi2);

javah takes a fully qualified class name so in your case that would be

com.ntv.ndkjni.test

As with all things related to java the class path is used to resolve the class based on the fully qualified name.  The name resolves STARTING at the path and then attempts to find the class BELOW the classpath by resolving the name.

Because of that your class path should be the following

C:\ndkJNI\src

Thanks a lot...

As your advices, I entry this   javah -jni -classpath C:\ndkJNI\src com.ntv.ndkJNI.test

Javah works clearly now.
