RE: Template -struts-template and generated HTML / templating using PUSH model
Many Thanks. It works OK now under Tomcat 3.2.1. Is there a problem in "flush" under Tomcat 3.2.1; in this case this patch would be appreciate for final Struts 1.0. Or is it my Tomcat configuration ?

The GetTag.java - the source behind the template:get tag that actually does the include calls pageContext and includes whatever content should go in. By default, the servlet engine should flush the buffer (that's what allows an include to go somewhere within your page). However, apparently some servers don't do that by default (WS 3.5.3 doesn't seem to). The solution is an easy one, but you'll need to recompile Struts. Under struts/src/share/org/apache/struts/taglib/template you will see a file called GetTag.java. Open that file. In the doStartTag() method you'll find the following code: pageContext.include(content.toString()); To fix your problem (hopefully, worked for me) add the following line above it: pageContext.getOut().flush(); So your end result will look like: pageContext.getOut().flush(); pageContext.include(content.toString()); By hardcoding the flush your problems should be solved. Recompiling struts is documented on the Struts installation web page. :) HTH, Chris Assenza -Original Message- From: Vincent Harcq [mailto:[EMAIL PROTECTED]] Sent: Wednesday, March 28, 2001 2:59 AM To: User Struts Subject: Template -struts-template and generated HTML / templating using PUSH model Hi, 1.

RE: Template -struts-template and generated HTML / templating using PUSH model
Merci. I will have a look at it. For my problem, I use . . . heuh, Tomcat 3.2.1 :( I just tried with Catalina 4.0b1 and . . . wow, it works fine :) Does I need a special parameter in server.xml, something else ???

Components proposal can be seen as "extended templates". With Components you can define your template's contents/attributes in a separate file, and insert content by using its name. A content, named a component, can also inherit from other definitions. Components proposal also contains other features. See (main site) http://www.lifl.fr/~dumoulin/components (mirror) http://www.geocities.com/cedricdumoulin/components/ I am currently working on the possibility to define or modify the template/component inside the action or inside the jsp. This will be available soon (see a previous mail 'Re: PROPOSAL: Template Screens'). Furthermore, useful Components features will be progressively introduce in Struts version 1.1 For your first question, see intermixed. Cedric Vincent Harcq wrote: > Hi, > > 1.

Templating Mechanism
After reading the User Guide, I am not sure if Struts does have a Templating Mechanism or not. By that I mean one (or 2 or 3) that defines the basic structure of the site in 3 (for example) parts : a header, the left panel and a body. This template will always be the jsp:forward and have two jsp:include to include the two static (for example) header and left panes pages and one jsp:include that would get a parameter from the request to now which page to include. Something similar to the PetStore example. I like that because it push a lot of DIV or LAYER HTML code in only the template page. Is it possible ? _ Do You Yahoo!?
