public class InitialQuestionsStep
extends AbstractProcessingStep

Initial Submission servlet for DSpace. Handles the initial questions which are asked to users to gather information regarding what metadata needs to be gathered.

This class performs all the behind-the-scenes processing that this particular step requires. This class's methods are utilized by both the JSP-UI and the Manakin XML-UI

Method Detail

doProcessing

public int doProcessing(Context context,
               javax.servlet.http.HttpServletRequest request,
               javax.servlet.http.HttpServletResponse response,
               SubmissionInfo subInfo)
                 throws javax.servlet.ServletException,
                        java.io.IOException,
                        java.sql.SQLException,
                        AuthorizeException

Do any processing of the information input by the user, and/or perform step processing (if no user interaction required)

It is this method's job to save any data to the underlying database, as necessary, and return error messages (if any) which can then be processed by the appropriate user interface (JSP-UI or XML-UI)

NOTE: If this step is a non-interactive step (i.e. requires no UI), then it should perform *all* of its processing in this method!

Specified by:

doProcessing in class AbstractProcessingStep

Parameters:

context - current DSpace context

request - current servlet request object

response - current servlet response object

subInfo - submission info object

Returns:

Status or error flag which will be processed by doPostProcessing() below! (if STATUS_COMPLETE or 0 is returned, no errors occurred!)

Throws:

javax.servlet.ServletException

java.io.IOException

java.sql.SQLException

AuthorizeException

getNumberOfPages

public int getNumberOfPages(javax.servlet.http.HttpServletRequest request,
                   SubmissionInfo subInfo)
                     throws javax.servlet.ServletException

Retrieves the number of pages that this "step" extends over. This method is used to build the progress bar.

This method may just return 1 for most steps (since most steps consist of a single page). But, it should return a number greater than 1 for any "step" which spans across a number of HTML pages. For example, the configurable "Describe" step (configured using input-forms.xml) overrides this method to return the number of pages that are defined by its configuration file.

Steps which are non-interactive (i.e. they do not display an interface to the user) should return a value of 1, so that they are only processed once!

Specified by:

getNumberOfPages in class AbstractProcessingStep

Parameters:

request - The HTTP Request

subInfo - The current submission information object

Returns:

the number of pages in this step

Throws:

javax.servlet.ServletException

processVerifyPrune

protected void processVerifyPrune(Context context,
                      javax.servlet.http.HttpServletRequest request,
                      javax.servlet.http.HttpServletResponse response,
                      SubmissionInfo subInfo,
                      boolean multipleTitles,
                      boolean publishedBefore,
                      boolean multipleFiles)
                           throws javax.servlet.ServletException,
                                  java.io.IOException,
                                  java.sql.SQLException,
