ServletWorker
public class ServletWorker (Code)
 ServletWorker is the base class for all servlet workers.
 ServletWorkers assume that the result can be returned in any of
 three formats : html, xml, or serialized java object.  These
 formats are specified by the URL format parameter, i.e.
 http://localhost:8800/$AGENT_NAME/SERVLET_NAME?format=html
 The format parameter is set in the getSettings method.  This should
 be called from a subclass if overridden.
 Defines the writeResponse method, which returns the type of result
 indicated by the format parameter to the output stream of the servlet 
 response.
 Note that if you make a mistake and don't provide a value for a 
 parameter, e.g.
 http://localhost:8800/$AGENT_NAME/SERVLET_NAME?format
 ^^^^ - no value
 the ServletUtil object will throw an exception.

FORMAT_DATA
final public static int FORMAT_DATA(Code)



FORMAT_HTML
final public static int FORMAT_HTML(Code)



FORMAT_XML
final public static int FORMAT_XML(Code)



VERBOSE

Method Detail
eq
final public static boolean eq(String a, String b)(Code)



execute
public void execute(HttpServletRequest request, HttpServletResponse response, SimpleServletSupport support) throws IOException, ServletException(Code)
Main method.

Most of the work is done in getHierarchy. This method mainly checks that the parameters are the right number and sets the format and recurse fields.

Uses the ServletUtil to parse the parameters.

getSettings
protected void getSettings(String name, String value)(Code)

 format  is either data, xml, or html
 see class description for what these values mean
 



isDataFormat
protected boolean isDataFormat()(Code)



isHtmlFormat
protected boolean isHtmlFormat()(Code)



isXmlFormat
protected boolean isXmlFormat()(Code)



writeResponse
protected void writeResponse(XMLable result, OutputStream out, HttpServletRequest request, SimpleServletSupport support, int format)(Code)
Write XMLable result to output.

Output format is either data, xml, or html
