Embedding a portlet in web content

Company Blogs 8. Dezember 2010 Von Barrie Selack

 Many people have asked, "How can I embed a portlet in web content". It's actually quite simple, once you know how. So I'll walk you through it.

It;s done via a runtime-portlet tag. The actual syntax looks like this:

<div id="embedded-welcome-portlet">
  <runtime-portlet name="47" instance="4433" queryString=""/>
</div>

(47 is the Hello World portlet)
 
The divs are not necessary, but in order to style the embeded portlet later we need them there.
 
So here is the Structure for the web content with the three pieces of information to pass to the runtime-portlet tag. (If you want, you can use hard coded values in the template of the web content)
 
 
And the template for the web content..
 
 
The template contains...
 
<p>
This is web content, with an embedded portlet!
</p>
 
<div id="embedded-welcome-portlet-$instance-id.getData()">
   <runtime-portlet name="$portlet-id.getData()" instance="$instance-id.getData()" queryString="$query-string.getData()"/>
</div>
 
Where the values from the template are passed in. We're not using the query string for this example.
 
So when rendered, it looks like this...
 
 
And there we have the Hello World portlet in our web content. But I really don't like that frame and title, so lets use CSS to style it.
 
In the web content use the configuration (little wrench) and select "Look and Feel"
 
Then we'll put the CSS under "Advanced Styling" This will use standard portlet CSS styles to change the look. Below is what gets set. Here's where we use the div id to make sure we only style out portlet.

 

 

Then the rendered web content will look like this.

 

But what if you want to use your own portlet? No problem, just use the name it is given by Liferay. In this case we'll use the Web Form portlet since it's not a Liferay built in portlet.

 

 

And now the web content looks like...

 

If the embedded portlet has a configuration option, you can configure it like any portlet to have different values on every page. You can also use the portlet's own Look and Feel to remove the borders or set a custom title. The WebForm portlet does have it's own configuration options (Hello World does not) Unfortunately at this time, you cannot use it's own configuration Look and Feel to style it, as the Web Content that contains it, overrides it's styling. 

 

Since one of the parameters is an instance-id, you can have multiple embedded instances of the same portlet on the page as below.

And there you are! A portlet embedded in web content.

If you're interested in more leave a comment. Thanks for reading.

Ok, so I can put portlet instance in my webcontent. Does it mean that on every page that web content is displayed that portlet will have the same configuration? An when I change this portlet config will it change on all sites? As I recall I can have many pages with same portlet instance (for example by using Page Templates) but their configuration is separated for every page

Same Web Content can be displayed automaticaly on different pages of Portal. In such case you will have to configure you portlet on multiply pages. In websites as big as news portals you want have time to do that. Is there any way to prepare global configuration for portlet instance?

For example I have news portal with such sitemap:
- home page
-- Sport
---- football
---- tennis
-- Moto
---- Cars
---- Vans

In news portals same web content is displayed in various places. In this case My article will be shown on pages like Cars, Moto and Home Page (beacuse it's about Batmans new batmobile). Now I want to show under that article a lists of other articles related to this one by tags. So I embedded Asset Publisher and configure it (using Cars page) to show "Web contents containing any tag: batmobile, car".

The problem is I want to define this configuration just once and for every place this article will be shown at (home page and Moto). Is there any way to do that?

Thanks for sharing Barry. This is one of the cool features that got me started using Liferay back in version 3.x.
Gepostet am 09.12.10 17:23.
Good article and good example how you can use web content.

Adding portlet to wcm template was new for me - anyway with same principles, it is possible to integrate iframe, flash .. youtube.. etc. to Liferay also. This is just by clever using of Web content as configuration repository (which already have editor also).

Btw, how this effect on Liferay and page caching, mainly to cache filter, which does not recognize if the page has embedded portlets on resources (like theme)?

Hi Barrie, we are using this runtime portlet tag since two years in our web sites as well. In most cases, it is just working fine.

But we encountered some limitations you should be aware of:
1. The tag can only be used in templates; raw HTLM articles just ignore it.
2. The portlets that are included via the runtime portlet tag are not considered when exporting a community into a lar file, doing staging or remote publishing.
3. If you include a web content portlet, it will not be found by a community search, because the entry in the JournalArticleSearchEntry table is missing.
4. You must not include a web content portlet into itself (i.e. use the instance id of the web content portlet that contains the runtine portlet tag as value). If you do so, you will end up with a stack overflow due to infinite recursion.

Best regards,
Olaf

Hello Everybody!
I'm a student come from VietNam!
I'm studying about Richface framework!
I had got a problem in JSF(Richface) Portlet when I used JavaScript!
That problem is : I could not get a value into a <h:inputText /> with JavaScript!
Can anybody help me?
Thank you very much!

This is my code:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html">

<f:view>
<script type="text/javascript">
function check() {
var result = document.getElementById("myform:form").value;
alert(result);
}
</script>

<h:form id="myform">

<h3>Hello :</h3>

<h:inputText value="" id="form" />

<h:commandButton value="OK" onclick="check();"/>

</h:form>

</f:view>

</ui:composition>

Cool feature, but how do you set portlet preferences? I saw the runtime-portlet tag has a defaultPreferences attribute... how would you pass preferences in a VM journal article template?
Gepostet am 28.01.11 06:22.
I'm have real trouble getting this to work. I'm running this from a development system, so the potential for a permissions issue is there, but even copying the Hello World example code above is not letting me put the portlet into my template.

What am I missing here? The portlet-runtime tag is coming through, but it doesn't appear to be getting parsed into an actual portlet.
Gepostet am 21.03.11 07:47.
Okay, I fixed the first issue I was having (this ONLY works through the web content portlet, not asset manager or any of the others), but now I'm having an issue with the queryString parameter. I'm trying to invoke the webProxy portlet in a template and set the url of the page that the portlet is proxying, but no matter how I format the queryString, this is not working.

<runtime-portlet name="66" instance="1284" queryString="initUrl=http://somewebaddress.com"/>

Please help.

A serious question...

Can this runtime-portlet tag be used in all other portlets (eg document and image "properties" or blogs and wiki)? I alos think it needs a bit more information - or a link to another blog/wiki article about the query string and other parameters that can be passed to the runtime-portlet tag.

You will see form my forum postings I have been trying to add a pagelet from a new portlet (handling Dublin Core categorization items) into a lot of other portlets but no one even suggested this tag. I would need to pass the current groupId and object Id (blog post etc) to make it work.
