Class SimpleNNTPHeader
java.lang.Object
org.apache.commons.net.nntp.SimpleNNTPHeader
public class SimpleNNTPHeader
extends java.lang.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;
