My question regarding the example code listed at the top of the MultipartStream class javadoc page: What is OutputStream output for? Is it for the "out" variable? I'm getting an error with my current code saying I have to initialize it... how do I do this? I was reading through the javadoc and supposedly readBodyData(OutputStream) is supposed to give the outputstream a value, but is there some kind of initialization I have to do before hand? Like point the OutputStream towards the "out" variable somehow? I've messed around with the example correcting the errors and stuff, declaring variables and giving them instances, and I just want to get something that works on Tomcat so I can fiddle with it and see what the different functions do. So far I have: <%@ page session="false" %> <%@ page import="org.apache.commons.fileupload.*" %> <%@ page import="java.lang.*" %> <%@ page import="java.io.*" %> <%@ page import="java.util.*" %> 
<%
if(FileUpload.isMultipartContent(request)){
  // request is a multipart/form-data,
javax.servlet.http.HttpServletRequest Interface Object
  out.println("lalala");

  //Enumeration eHeaderNames = new Enumeration;
  
  InputStream input = request.getInputStream(); // new InputStream();
  byte[] boundary = new byte[4096];
  
  String header;

  try {
    MultipartStream multipartStream = new MultipartStream(input,
boundary);
    boolean nextPart = multipartStream.skipPreamble();
    OutputStream output;
    PrintWriter pw = new PrintWriter(output);
    
    while(nextPart) {
      header = multipartStream.readHeaders();
      // process headers


      // create some output stream
      multipartStream.readBodyData(output);
      nextPart = multipartStream.readBoundary();
    }
  }
  catch(MultipartStream.MalformedStreamException e) {
    // the stream failed to follow required syntax
  } catch(IOException e) {
    // a read or write error occurred
  }
}

rest What I'm trying to do ultimately is get the file in myfileupload to upload a text file which I will later parse, but I can't get the file upload to work so I'm trying to figure out how to get that part going. What I've resorted to is starting with this example code, correcting errors, defining variables before the code piece runs, and just generally trying to get something working. I'm hoping to get help from this mailing list, but if not I will keep looking through the javadocs and fumbling my way through the darkness. Thanks in advance for the help! -TJ --------------------------------------------------------------------- To unsubscribe, e-mail: commons-user-unsubscribe@jakarta.apache.org For additional commands, e-mail: commons-user-help@jakarta.apache.org
