Thanks, greetings I doubt if anyone has used Stripes for portlets, as servlets and portlets have an entirely different ecosystem around them (servlet container vs. portal). Also note that the portlet request cycle is different: action processing and rendering is separated. Also, much depends on the portlet version being used. The first specification doesn't allow extra resources such as CSS files, images, etc. and should be avoided (although I realize this choice is not always available). The portlets 2 and WSRP 2 specifications do allow these things, and thus can support Stripes. To make Stripes work with portlets would require these steps: 1. Convert the StripesFilter to a portlet filter. 2. Convert the StripesDispatcher servlet to a portlet (it mainly handles the lifecycle and lets other classes to the work, so this should be doable). 3. In the dispatcher portlet, store the Resolution obtained from the event handling, so it can be used during the rendering phase. As an added bonus, you'll need to: - resolve redirects (impossible for portlets), - ensure that the Resolution instance can be infinitely reused, - be aware that rendering properties can and will be stored (and thus reused) by the portal server, making selecting the default handler trickier Oscar -- ,-_ Oscar Westra van Holthe - Kind http://www.xs4all.nl/~kindop/ /() ) (__ ( The haves and the have-nots can often be traced back to the =/ () dids and the did-nots. signature.asc Description: Digital signature -- Download new Adobe(R) Flash(R) Builder(TM) 4 The new Adobe(R) Flex(R) 4 and Flash(R) Builder(TM) 4 (formerly Flex(R) Builder(TM)) enable the development of rich applications that run across multiple browsers and platforms.

Portlets ? Seriously ? Seriously... :P I was joking with the iframe thing, even if it might be a simple option to include some external content in a portlet, I don't know. The other option (the Stripes rewrite) is even more hackish to me ! Anyway, iframes are everywhere. Crappy but damn useful if you ask me :P Even Google has one on the front page...

Re: [Stripes-users] Stripes and Portlets
Hi Nikolaos I agree with you regarding the scalability an silverbullet issue. However, there will still be customers that wants to move around with web content, and present it using different configurations (portals) depending on different customers. The best shot at the moment might be Jsr286, but I haven't tried it out yet. Anyway, I am also tired of technologies that promises to save the world... Which is why I like stripes : Regards Søren Den 18/10/2010 19.00 skrev Nikolaos Giannopoulos nikol...@brightminds.org : Andres, Having worked with Portal Servers for many years... I have to say that in theory Portal servers are great. In practice there are A LOT of issues with them. The 2 biggest problems offhand are: 1) the fact that they ADD an entirely different layer on top of your web container being the portlet container and make simple web development a little more like rocket science (as if it isn't hard enough as it is at times). For this the iFrame is a classic solution. Yes - not what you might expect but heavily utilized in the Portal / Portlet space. 2) due to 1) they have a voracious appetite for CPU and memory... and as such have a litter of many failed projects... . And I don't mean small customers... I mean VERY large customers in the USA and Canada who give up on either a) buying all the extra hardware OR b) buying all the extra licenses for their app servers. I have had clients ask me with my enterprise box with X CPU's that should be enough... NO?... why the performance issues?... double the CPU and the #boxes if you can was my answer and you still will probably have scalability issues... they did and it didn't help :-) Portals were supposed to be the end all to Enterprise and aggregate the hundreds / thousands of local systems on an Intranet... instead they have met largely with failure on a grand scale and what I most often see are companies going back to building large web apps after they have experienced the Portal world. So it isn't surprising that Stripes lacks integration... and it isn't surprising that Spring MVC does... or whatever... what is surprising for me personally is to see people still trying to build or maintain sites around them ;-) --Nikolaos Mario Arias wrote: andres ispanand...@... writes: Hi all,I want to ask, if a... -- Download new Adobe(R) Flash(R) Builder(TM) 4 The new Adobe(R) Flex(R) 4 and Flash(R) Builder(TM) 4 (formerly Flex(R) Builder(TM)) enable the development of rich applications that run across multiple browsers and platforms.

Hi Oscar Sure, although I can't say when this will happen. I have created a bridge that copies some of the concepts in Jsr286, so it should be doable to make it 286 compliant, but we'll see.
