Welcome page with dynamic content (contentProducer?) [message #623873] Mon, 22 February 2010 16:33 Go to next message

Hi

I am attempting to write a contentProducer in order to forfill the following usecase:

I would like to be able to contribute content to my intro page determined by java logic.

I thought that using a contentProducer would be the way to go however I cant seem to get the contentProducer code to be executed.

This is my plugin xml for the plugin containing the intro
http://pastebin.com/m56ab9798

But I am unsure of how to reference the contentProducer so that it is invoked to create the content.

Any help would be greatly appreciated as I am struggling to find resources on the subject.

Alec

Hi Alec,

Your plugin.xml looks fine to me.

There is an example of this in the eclipse code for 3.6. Any recent build of Eclipse 3.6 should have the Network Error Page which is supplied by a Content Producer in the org.eclipse.help.webapp plugin, see /org.eclipse.help.webapp/src/org/eclipse/help/internal/webap p/StatusProducer.java

In order to reference the Content Producer, you need to use a URL that includes the plugin which contains the extension point for your Content Producer. In other words, for the example above , something like this:

help/topic/org.eclipse.help.webapp/NetworkHelpStatus.html

The getInputStream(String pluginID, String href, Locale locale) method of your Content Producer will be called anytime a reference is made to a topic inside of its parent plugin. At that time, it is best to check the request and see if it is a request for your dynamic content. If so, return an InputStream containing the dynamic content. If not, return null so that Eclipse can send the help request to any static content that may be available in the plugin.

Hi Chris

Its good to see an example and hear that I am along the right lines.

How can i reference the plugin in the intro page though?

At the moment I have a fullscreen.xhtml that i use as the root page. what tag should i use to make reference to the plugin (hence the producer) to create the dynamic content.

ie how do i actually use it, when i try to create a link to it such as <a href="a.b.c.d.e/test.html">test link</a> I get a search page provided by my dns provider. Meaning the page cant be found =(

Hi Alec,

You are probably looking for the showHelpTopic command, see the extension content example below:


<?xml version="1.0" encoding="utf-8" ?>
<introContent>
<extensionContent id="test-introExtension" style="css/sample.css" name="Sample Extension" path="overview/@">
<group style-id="content-group" id="test-introLink-group">
<link label="Error Page" url=" http://org.eclipse.ui.intro/showHelpTopic?id=/org.eclipse.he lp.webapp/NetworkHelpStatus.html" id="test-introLink" style-id="content-link">
<text>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</text>
</link>
</group>
</extensionContent>
</introContent>

The url=" http://org.eclipse.ui.intro/showHelpTopic?id=/org.eclipse.he lp.webapp/NetworkHelpStatus.html" directs the intro page right to the Content Producer.
