RMI中参数为Input出现的问题

Question

在JDK 的RMI中我有个方法需要传参数，参数为InputStream,在远程调用的的时候报错，
这是我客户端代码

[code="java"]
try {

ICheckServer rmi = (ICheckServer) Naming.lookup("rmi://127.0.0.1:2012/checkserver");

InputStream in = new Thread().getContextClassLoader().getResourceAsStream("jolt-config.xml");

         rmi.initTuxedoConnect(in);
    } catch (Exception e) {  
        // TODO Auto-generated catch block  
        e.printStackTrace();  
    }  

[/code]

错误信息：
java.rmi.MarshalException: error marshalling arguments; nested exception is:
java.io.NotSerializableException: java.io.BufferedInputStream

楼上哥们说的都对
在实际工作中，由于io stream 不支持序列化功能，所以不能直接传递到客户端
送一个类
[code="java"]
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;
@SuppressWarnings("serial")
public class DataSet implements Serializable{
private transient InputStream is;
public DataSet(InputStream is){
this.is = is;
}

public InputStream getInputStream(){
    return is;
}

private void writeObject(ObjectOutputStream out) throws IOException {
    out.defaultWriteObject();
    int c = -1;
    byte[] buff = new byte[1024];
    while((c = is.read(buff, 0, 1024)) != -1){
        out.write(buff, 0, c);
    }
}
private void readObject(ObjectInputStream in) throws IOException, ClassNotFoundException {
    in.defaultReadObject();
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    int c = -1;
    byte[] buf = new byte[1024];
    while((c = in.read(buf, 0, 1024)) != -1){
        bos.write(buf, 0, c);
    }

    //recreate the input stream here.
    is = new ByteArrayInputStream(bos.toByteArray());
}

}
