Class IWSAAtomServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.oclc.da.gdfr.registryprototype.atom.IWSAAtomServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class IWSAAtomServlet
extends javax.servlet.http.HttpServlet

Atom Servlet implements Atom protocol by calling an org.oclc.da.gdfr.registryprototype.atom.IWSAAtomHandler implementation. This servlet was inspired by the Apache implementation because the ROME Atom handling was simply too inefficient and performed highly redundant parsing. This implementation uses simple XSL stylesheets and little Java code to translate Atom requests into IWSA deposit records.
