Class HttpPager

java.lang.Object

org.xmlactions.web.conceal.HttpPager

public class HttpPager
extends java.lang.Object

Servlet implementation class PagerServlet

This class is used to manage http page requests.

It uses an IExeContext that must be defined in the Spring ApplicationContext with id "pager.execContext". This IExecContext is then extended with additional information such as

• execContext.put(ActionConst.WEB_REAL_PATH_BEAN_REF, realPath);
• execContext.put(ActionConst.PAGE_NAMESPACE_BEAN_REF, nameSpace);
• execContext.setSession(request.getSession(true));
• execContext.loadFromPersistence();
• execContext.addNamedMap(IExecContext.PERSISTENCE_MAP, execContext.getPersistenceMap());
• execContext.addNamedMap(PagerWebConst.REQUEST, params);
• execContext.put(PagerWebConst.REQUEST_LIST, paramList);
• execContext.put(PagerWebConst.PAGE_NAME, (pageName.length() > 1 ? pageName.substring(1) : pageName));
• execContext.put(PagerWebConst.PAGE_URI, request.getRequestURI());
• execContext.put(PagerWebConst.PAGE_URL, request.getRequestURL() .toString());
• execContext.put(PagerWebConst.PAGE_SERVER_NAME, request.getServerName());
• execContext.put(PagerWebConst.PAGE_APP_NAME, appName);
• execContext.put(ActionConst.WEB_ROOT_BEAN_REF, "");
• execContext.put(ActionConst.WEB_ROOT_BEAN_REF, "/" + appName);
• execContext.put(PagerWebConst.HTTP_REQUEST, request);
• execContext.put(PagerWebConst.HTTP_RESPONSE, response);
• execContext.put(PagerWebConst.HTTP_SESSION, request.getSession(true));
• execContext.put(PagerWebConst.EXEC_CONTEXT, execContext);

See PagerWebConst and org.xmlactions.action.ActionConst and org.xmlactions.action.config.IExecContext.

The IExecContext is available from the code by calling org.xmlactions.web.RequestExecContext.get().
