Hi,
i have deployed a portlet that supports the VIEW, EDIT and HELP mode. When
applying the EDIT operation i am redirected to the default page of the portal.
This causes that i can't see the result's of the EDIT operation. How can I
force JBP2 to stay on the same page.
A second question: Why do i have to reference a portltet instance in
*-pages.xml with this cryptic string
<instance-ref>advancedportlet.AdvancedPortlet.AdvancedPortletInstance</instance-ref>
instead of <instance-ref>AdvancedPortletInstance</instance-ref> as defined in
the portlet-instances.xml?
Here is the portlet code. It is the modified example from the portal book
chapter 2.
| package com.portalbook.portlets;
|
| import java.io.IOException;
| import java.io.Writer;
|
| import javax.portlet.ActionRequest;
| import javax.portlet.ActionResponse;
| import javax.portlet.GenericPortlet;
| import javax.portlet.PortletException;
| import javax.portlet.RenderRequest;
| import javax.portlet.RenderResponse;
|
| public class AdvancedPortlet extends GenericPortlet
| {
|
| protected void doEdit(
| RenderRequest renderRequest,
| RenderResponse renderResponse)
| throws PortletException, IOException
| {
| renderResponse.setContentType("text/html");
|
| Writer writer = renderResponse.getWriter();
|
| //get the existing parameters to use as defaults.
| String title = renderRequest.getParameter("title");
| String contents = renderRequest.getParameter("contents");
|
| if (title == null)
| {
| title = "";
| }
|
| if (contents == null)
| {
| contents = "";
| }
|
| writer.write("<H1>Portlet Settings</H1>");
| writer.write("<FORM ACTION=");
| writer.write(renderResponse.createActionURL().toString());
| writer.write(">");
|
| writer.write(
| "Title: <INPUT TYPE=text NAME=title VALUE='" + title + "'
SIZE=25>");
| writer.write(
| "Contents: <INPUT TYPE=text NAME=contents VALUE= '"
| + contents
| + "' SIZE=25>");
| writer.write("<P>");
| writer.write("<INPUT TYPE=submit>");
| writer.write("</FORM>");
|
| }
|
| protected void doHelp(
| RenderRequest renderRequest,
| RenderResponse renderResponse)
| throws PortletException, IOException
| {
| //return a helpful message
| renderResponse.setContentType("text/html");
|
| Writer writer = renderResponse.getWriter();
| writer.write(
| "This portlet allows you to change its content and title.");
| }
|
| protected void doView(
| RenderRequest renderRequest,
| RenderResponse renderResponse)
| throws PortletException, IOException
| {
| renderResponse.setContentType("text/html");
| Writer writer = renderResponse.getWriter();
| String contents = renderRequest.getParameter("contents");
| if (contents != null)
| {
| writer.write(contents);
| }
| else
| {
| //return the default contents
| writer.write("This is the default portlet contents. To change
");
| writer.write("this message, edit the portlet's settings.");
| }
| }
|
| protected String getTitle(RenderRequest renderRequest)
| {
| String title = renderRequest.getParameter("title");
| if (title != null)
| {
| return title;
| }
| //else return a default title, if we don't have one set yet.
| return "Advanced Portlet";
| }
|
| public void processAction(
| ActionRequest actionRequest,
| ActionResponse actionResponse)
| throws PortletException, IOException
| {
| //check for parameters
| String title = actionRequest.getParameter("title");
| if (title != null)
| {
| actionResponse.setRenderParameter("title", title);
| }
|
| String contents = actionRequest.getParameter("contents");
| if (contents != null)
| {
| actionResponse.setRenderParameter("contents", contents);
| }
| }
| }
|
