java “Class file contains wrong class” error

问题

I'm trying to make a console application to test my webservice. I successfully deployed a webservice at http://localhost:8080/WS/myWS and i made proxy classes with wsimport:

wsimport -d bin -s src http://localhost:8080/WS/myWS?wsdl

Now my webservice classes are located in bin/mywebservice/ and i'm trying to compile my client class with classpath = ./

Here's the source code of my class:

import bin.mywebservice.myClass_Service;
public class TesterApp{
    public static void main (String args[])
    {    
        myClass_Service service = new myClass_Service(); 
    }
}

And i have error:

TesterApp.java:1: error: cannot access myClass_Service
import bin.mywebservice_Service.myClass;
                               ^
  bad class file: .\bin\mywebservice\myClass_Service.class
    class file contains wrong class: mywebservice.myClass_Service
    Please remove or make sure it appears in the correct subdirectory of the classpath.

please help, what's wrong with myClass_Service? i swear, myClass_Service.class exists in .\bin\mywebservice\

回答1:

You're incorrectly including the bin in the import declaration.

Rather put bin on the classpath and correct the import.

Unless (the poorly-named) myClass_Service.java file is package bin.mywebservice (which it isn't, according the the error message), you're trying to correct the problem in the wrong place.

回答2:

It looks like the generated class has a package mywebservice, not bin.mywebservice. Make sure the bin directory is on the classpath, and drop bin from the packages.

回答3:

This makefile may help if you are using packages:

CLASS_PATH = ../bin

vpath %.class $(CLASS_PATH)

all : HelloJNI.h

HelloJNI.h : com/my/package/HelloJNI.class
    javah -classpath $(CLASS_PATH) com.my.package.$*
