Question

我有以下名为Test.Java的文件，其代码为

package example25;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.util.Iterator;
import org.jibx.runtime.BindingDirectory;
import org.jibx.runtime.IBindingFactory;
import org.jibx.runtime.IMarshallingContext;
import org.jibx.runtime.IUnmarshallingContext;
import org.jibx.runtime.JiBXException;

public class Test 
{   
public static void main(String[] args) 
{

    try
    {

        // unmarshal customer information from file
        IBindingFactory bfact = BindingDirectory.getFactory(Order.class);
        IUnmarshallingContext uctx = bfact.createUnmarshallingContext();
        FileInputStream in = new FileInputStream("D:\\Java Libraries\\jibx\\dwcode2\\starter.xml");
        Order order = (Order)uctx.unmarshalDocument(in, null);

        // compute the total amount of the order
        float total = 0.0f;
        for (Iterator<Item> iter = order.getItemList().iterator(); iter.hasNext();)
        {
            Item item = iter.next();
            total += item.getPrice() * item.getQuantity();
        }
        order.setTotal(new Float(total));

        // marshal object back out to file (with nice indentation, as UTF-8)
        IMarshallingContext mctx = bfact.createMarshallingContext();
        mctx.setIndent(2);
        FileOutputStream out = new FileOutputStream("c:\\out.xml");
        mctx.setOutput(out, null);
        mctx.marshalDocument(order);
        System.out.println("Processed order with " +  order.getItemList().size() + " items and total value " + total);

    }
    catch (FileNotFoundException e)
    {
        e.printStackTrace();
        System.exit(1);
    } catch (JiBXException e)
    {
        e.printStackTrace();
        System.exit(1);
    }
}//end main

}//end class

以下是我试图编译此文件和我得到的输出

Test使用的所有类文件都在它旁边并且已经正确编译。测试是给我带来麻烦的最后一个文件。此外，测试中使用的一些类存在于C：\ jibx \ lib＆gt;中。而不是C：\ jibx \ tutorial＆gt;从我执行命令的地方。关于如何在不修改我以前生成的类文件的情况下解决此问题的任何建议将不胜感激。

Answer 1

将目录C：\ jibx \ lib添加到类路径中，例如

SET CLASSPATH=%CLASSPATH%;C:\jibx\lib;.

然后做一个javac

Answer 2

由于存在一些导入错误，所以正确设置类路径，如Satya所说，并且您在某个目录中的当前类应该使用javac的-d属性进行编译如下图所示

javac -d。 YourfileName.java

如何使用javac正确编译此文件
