Question

javah -jni problem with compiling my package

Asked by: asmyatt

i'm trying to compile some java code on Solaris 10.

let's say I have the class MyClass in the file MyClass.java and it is located in the directory /export/home/asmyatt/TestApp/com/MyPackage/

at the top of MyClass.java I have
package com.MyPackage;

Then I do the following:
javac MyClass.java  *** It compiles with no errors ***
javah -jni MyClass

When I run this statement I get the following error:

error: cannot access MyClass
bad class file: ./MyClass.class
class file contains wrong class: com.MyPackage.MyClass
Please remove or make sure it appears in the correct subdirectory of the classpath.
com.sun.tools.javac.util.Abort

        at com.sun.tools.javah.Main.main(Main.java:147)
javadoc: error - fatal error
2 errors


*****************************
If I remove the package statement at the top it works fine. The only problem then is i don't know how to get the additional classes in the package to see the compiled class file.

I would prefer that it let me put this class in the package. Any suggestions as to what I'm doing wrong?

If suppose your MyClass exists in the following path..

/export/home/user/com/MyPackage/MyClass.class then...
Use the following command..

javah -classpath /export/home/user/ -jni  com.MyPackage.MyClass

This is what worked:
javah -classpath /export/home/smyatt/TestApp -jni  com.MyPackage.MyClass
