Inspect Tile Definitions
Hi All, We're using Struts Tiles 1.3.5 in Spring 2.0 on Tomcat 5.5 and Java 1.6. With Spring, we're loading a view that is a Tile definition. That Tile loads several other Tiles respectively. Some of those sub-Tiles include global advertising Tiles such as the banner ad, a square ad, a pop-under ad, etc. The ad system we are using requires us to make one call to the ad server to get all of the ads needed for the page. In our first pass, we put flags in each ad Tile to indicate that our footer AJAX should retrieve the ads required by the Tiles inserted. This works ok, but we have some technical difficulties with post-render ad positioning that are causing us to consider alternatives. We were wondering if there is any way for us, in the primary view Tile, to inspect the Tile definitions that WILL be loaded into the page. Then we can simply determine if certain Tiles are present, we can insert the ads proactively as the page is constructed. Any suggestions? Thanks! -Ryan Shelley

I don't know if it's useful, but you could use a Tiles controller to preprocess your definition: http://struts.apache.org/1.3.8/apidocs/org/apache/struts/tiles/Controller.html The ComponentContext parameter has all the attributes that will be used in the definition.

RE: Inspect Tile Definitions
Thanks for the prompt response! We're using Spring Controllers and not Struts Controllers. Tiles is the only Struts component we're using. Unfortunately, we have hundreds of Spring Controllers, and it wouldn't be feasible to refactor them all to use a separate Controller type.

No wait, Tiles controllers are a totally different concept (in fact the name was pretty unfortunate, in Tiles 2 we renamed it into preparer). The Tiles controller is specified into the XML definition files, for example: definition name=my.definition page=/my/page.jsp controllerClass=my.package.MyControllerClass ... /definition HTH Antonio - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Inspect Tile Definitions
Interesting! Is there a URL to some documentation or examples or are there any examples of Tile Controllers in any of the packages? So in theory, if we put a custom Tile Controller on the primary Tile definition, that Controller class could inspect down into the Tile tree for that view and set page-level values that could be accessed when the JSP is rendered? -Ryan -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Antonio Petrelli Sent: Tuesday, September 30, 2008 11:51 AM To: Struts Users Mailing List Subject: Re: Inspect Tile Definitions 2008/9/30 Shelley, Ryan [EMAIL PROTECTED]: Thanks for the prompt response!

RE: Inspect Tile Definitions
Well, I just need to know if Tile definitions A, B and C are in the chain of Tiles to be inserted in the particular page render, and if so, put some variables in the Request or Page scope for the JSP to pick up during render. -Ryan -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Antonio Petrelli Sent: Tuesday, September 30, 2008 12:04 PM To: Struts Users Mailing List Subject: Re: Inspect Tile Definitions 2008/9/30 Shelley, Ryan [EMAIL PROTECTED]: Interesting!

RE: Inspect Tile Definitions
When I use ComponentContext and get the attributes in the context, is there a way to determine that attribute A is a Tile and I can then drill into that Tile and get a list of its attributes? Can I do an instanceof against the Object returned from getAttribute to compare it to some class that will have getAttribute and getAttributeNames methods? -Ryan -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Shelley, Ryan Sent: Tuesday, September 30, 2008 1:26 PM To: Struts Users Mailing List Subject: RE: Inspect Tile Definitions Well, I just need to know if Tile definitions A, B and C are in the chain of Tiles to be inserted in the particular page render, and if so, put some variables in the Request or Page scope for the JSP to pick up during render. -Ryan -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Antonio Petrelli Sent: Tuesday, September 30, 2008 12:04 PM To: Struts Users Mailing List Subject: Re: Inspect Tile Definitions 2008/9/30 Shelley, Ryan [EMAIL PROTECTED]: Interesting!

RE: Inspect Tile Definitions
I considered putting the Tile Controller on each Ad Tile that would collect Ad codes to expose to in the request, which works, except that each Tile is rendered and flushed to the browser one at a time, so by the time the last Ad is processed, the header (which contains the Ad engine code) has already been sent to the browser. Ideally, we'd be able to inspect each Tile that WILL be loaded and then put a string of Ad codes in the request before the page is rendered so the Ad Engine code in the header will have a complete list of all the Ads to be rendered on the page. -Ryan -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Antonio Petrelli Sent: Tuesday, September 30, 2008 12:04 PM To: Struts Users Mailing List Subject: Re: Inspect Tile Definitions 2008/9/30 Shelley, Ryan [EMAIL PROTECTED]: Interesting!
