java - non-static method encode(byte[]) cannot be referenced from a static context -

- 

package com.cordys.report;  import java.io.fileinputstream;   import org.apache.commons.codec.binary.base64;   public class encode { public static string encodefilestream(string filepath) //file path ex : c:\program files\cordys\web\reports\i0001180.pdf {     try {    fileinputstream fin = new fileinputstream("e:/css document/test.pdf");    stringbuffer sb=new stringbuffer();    int linelength = 72;    byte[] buf = new byte[linelength/4*3];    while (true) {      int len = fin.read(buf);      if (len <= 0) {       break;      }     sb.append(base64.encode(buf));     return sb.tostring();  }  }  catch(exception e) {    return e.getmessage();  } }    }

as seen @ http://commons.apache.org/codec/apidocs/org/apache/commons/codec/binary/base64.html

try base64.encodebase64() instead.
