actually portlet has to use the request.getResponseContentType() to know which mime type has been decided for that request.

Truth, but markup!=MIME. For example:

Markup MIME
--------------------------------------
html text/html
chtml text/html
xhtml text/html
wml text/vnd.wap.wml

This meens, we have the same MIME for different markups. In fact, portlet would "like" to know what markup is expected by the current User Agent and it would form the corresponding content.
We have the tag. It's rendered in different way in WML and cHTML/xHTML. There are more difference(, and so on), quite small but important . My idea is to provide portlets with all information which can be important when the content is rendered. So, I think we could provide this info in a header. What do you think about it ?

Well, my example tags were taken into account by the forumin my previous post ;) .

[julien1]

what are the differences between CHTML and others (HTML and XHTML) ?

what are the differences between CHTML and others (HTML and XHTML) ?

Most of those differences are related to markup tags and their attributes - it depends how device renders certain tag and it's attributes. Some devices simply ignores the rest part of content if "unsupported" combination is found. Please, take a look at this refference, here you'll find most of differences with markups:

That's why I would like to provide portlets with additional info regarding markups preferred by certain User Agent.

[julien1]

so the best place would be the request properties under a specific key

Where can I look for an example ? I mean, the existing portal's code.

[julien1]

I have addd support for the preferred markup in the code base.
Look at the test portlet example in the core.

Thank you Julien.

P.S.: could you recommend a way how to connect to the CVS repository if I'm behind the proxy ? Can I do that with Eclipse ?

[julien1]

unfortunately I have no solutions for this
we should make the nightly CVS available for download as we did for nukes.

Is this available already ?

Hi Julien.

yes, you should work on that I think. This should be done as a an interceptor placed after the ViewInterceptor. It needs to iterate all the windows selected for this request and retain only those who can produce the selected content type.

On the Window object you can get the Instance and on the Instance you can get the Component object.

On that Component object you have a method getContentTypes() which returns a plugin of the component responsible for managing the associations between component and content types.

Well, it seems I need more information on selecting right components accorting to their supported MIME type.

1. I get the request :

PortalRequest request = (PortalRequest)invocation.getAttachment(AttachmentKey.PORTAL_REQUEST);

2. Then I get the window :

Window window = (Window)invocation.getAttachment(AttachmentKey.WINDOW);

3. After that I get the MetaDataHolder :

MetaDataHolder mdh = window.getInstance.getComponent().getPlugin(plugin).getMetaData();

Question #1 - what is the correct value of "plugin" ?
Question #2 - how to check the MIME type supported by the concrete component of the wondow ?

Please, explane the idea in more details. All information is quite fragmented and it is difficult to get the whole picture.

Thank you in avance.

Cheers,
Arturas

so you have the window, you do getInstance then getComponent.

once you have the component you look for the plugin org.jboss.portal.server.PortalConstants.PLUGIN_PREFS

there you have an instance of org.jboss.portal.server.plugins.mode.ContentTypes you can use the method isContentTypeSupported that checks if the component supports a specific content type

Thanks Julien, that's pretty clear. One more question - how do I exclude the component if it doesn't support the current MIME type ? What is the technique ?

[julien1]

look at the org.jboss.portal.core.invocation.ViewInterceptor, I think you should integrate here because this is the place that the view is built.

[arturasb]

Is the single <mime-type> tag per portlet allowed ?
