How to share portlet headers

[infoni]

Hi,

In the screenshot below (Gatein 3.6.final Tomcat 7 bundle),  there are 4 portlet windows:

- 3 portlet windows to enter a parameter

- 1 portlet window to display a BIRT report.

- Both report and parameter applications reside in the same .WAR deployment, and they use the same javascript & css headers (same ID, same URL)

- These headers are injected by overriding "doHeader" method, as it is recommended with Gatein

Unfortunately, headers are injected for each portlet window, resulting in this html head section:

Did we miss something? Is there a mechanism in Gatein  to detect which headers are shared between portlets, before generating a page?

Thanks

For portlet javascript and css files, the recommended approach is to use the gatein-resources.xml file to configure them.

Thank you Matt!

After a tough fight i was able to define a shared javascript resource in gatein-resources.xml, and link it to my two portlets with a dependency. It works very well: now the javascript resource is included just one time, whatever the number of portlet windows on the page

Though i still have troubles with css. I declared this in gatein-resources.xml:

  <portlet-skin>

    <application-name>myAppName</application-name>

    <portlet-name>myPortletReport</portlet-name>

    <skin-name>Default</skin-name>

    <css-path>/resources/css/myCustomStyle.css</css-path>

  </portlet-skin>

  <portlet-skin>

    <application-name>myAppName</application-name>

    <portlet-name>myPortletParameter</portlet-name>

    <skin-name>Default</skin-name>

    <css-path>/resources/css/myCustomStyle.css</css-path>

  </portlet-skin>

When i open a page containing  "myPortletReport" and "myPortletParameter" (such showed as example in the first post), it nearly works but i have two problems:

• Images are not found by my custom css rules. These images are in a relative folder /images (so it is located in my webapp at  /resources/css/images). They were correctly taken in consideration with "doHeaders" method but not when using  a portlet-skin. It seems the portal shadows the css in a working folder, but i have not found out a way to include an image folder as well.
• It is now including two links such below: one link with an ID myPortletReport, and another with ID myPortletParameter. Thats much better than initial situation which added 4 links, but is it possible to  change the setup to include only one link, like for javascript resources?

http://localhost:8080/portal/skins/3.6.0.Final/myAppName/resources/css/myCustomStyle-lt.css

Any idea?

Thanks!
