Class SimpleNNTPHeader

    java.lang.Object
      org.apache.commons.net.nntp.SimpleNNTPHeader

public class SimpleNNTPHeader
extends Object

This class is used to construct the bare minimum acceptable header for most news readers. To construct more complicated headers you should refer to RFC 822. When the Java Mail API is finalized, you will be able to use it to compose fully compliant Internet text messages.

The main purpose of the class is to faciliatate the article posting process, by relieving the programmer from having to explicitly format an article header. For example:

     writer = client.postArticle();
     if(writer == null) // failure
       return false;
     header = new SimpleNNTPHeader("foobar@foo.com", "Just testing");
     header.addNewsgroup("alt.test");
     header.addHeaderField("Organization", "Foobar, Inc.");
     writer.write(header.toString());
     writer.write("This is just a test");
     writer.close();
     if(!client.completePendingCommand()) // failure
       return false;
