难以用Javac编译 - 问题

Question

我有以下目录结构c:\ jibx\tutorial\example23 \示例23包含以下文件

现在我正在尝试编译仅引用此文件夹中其他类的CustomerManager java文件.CustomerManager java文件的代码很简单

package example23;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import org.jibx.runtime.*;

public class CustomerManager 
{

                 public CustomerManager()
                 {
            try 
            {
            IBindingFactory bfact = BindingDirectory.getFactory(Customer.class);
            IUnmarshallingContext uctx = bfact.createUnmarshallingContext();

            Object obj = uctx.unmarshalDocument(new FileInputStream("C:/jibx/tutorial/example23/customer.xml"), null);
            Customer customer = (Customer)obj;
            System.out.print(customer.street+", "+customer.city);
            IMarshallingContext mctx = bfact.createMarshallingContext();
            mctx.setIndent(4);
            mctx.marshalDocument(obj, "UTF-8", null, new FileOutputStream("C:/jibx/tutorial/example23/customer2.xml"));
            } 
            catch (FileNotFoundException e) 
            {
            e.printStackTrace();
            } 
            catch (JiBXException e) 
            { 
            e.printStackTrace();
            }
                  }   //end method

 public static void main(String[] args) 
 {
 new CustomerManager();
 }

 }//end class

现在这个文件包含对其顶层目录中文件的引用,例如c:\ jibx\lib(文件本身位于c:\ jibx\tutorial\example23中)

我尝试了以下内容来引用这些库并编译该文件

C:\jibx\tutorial>javac  -classpath c:\jibx\lib\  example23\CustomerManager.java

and the output i got was
example23\CustomerManager.java:7: error: package org.jibx.runtime does not exist

关于我如何解决这个问题的任何建议？

Answer 1

我认为你的问题在于以下几行

-classpath c:\jibx\lib\

该目录是否包含jar文件？

在这种情况下,你可以尝试使用像这样的glob:

-classpath c:\jibx\lib\*.jar

这样,您将在类路径的c:\ jibx\lib \目录中包含所有jar文件.
