Binary file producing with REST

2011-03-03T17:09:00.000-08:00

Now I would like to share my experience about generating binary content with REST.
This is just a simple example. The focus is on using StreamingOutput API.
Below is the sample source for providing zip file from http request.

package com.test;

import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.net.URL;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.StreamingOutput;

import org.apache.commons.io.IOUtils;



@Path("/zipfileservice/")
public class ZipService {

 @GET
    @Path("/helloWorld/{caller}/") 
    @Produces("application/text")
 public String helloWorld(String caller) throws Exception{
  return "Hello";
 }
 @GET
    @Path("/helloWorldZip/{caller}/") 
    @Produces("application/zip")
 public StreamingOutput helloWorldZip(String caller) throws Exception{
  return new StreamingOutput(){

   @Override
   public void write(OutputStream arg0) throws IOException, WebApplicationException {
    // TODO Auto-generated method stub
    BufferedOutputStream bus = new BufferedOutputStream(arg0);
    try {
     //ByteArrayInputStream reader  = (ByteArrayInputStream) Thread.currentThread().getContextClassLoader().getResourceAsStream();     
     //byte[] input = new byte[2048];  
     URL uri = Thread.currentThread().getContextClassLoader().getResource("");
     File file = new File(uri.getPath()+File.separator+"WHATSNEW.zip");
     FileInputStream fizip = new FileInputStream(file);
     byte[] buffer2 = IOUtils.toByteArray(fizip);
     bus.write(buffer2);
    } catch (Exception e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }
   }
   
  };
 }
}
