RE: Re[2]: xml,xsl in orion
Ok..that sounds great. Now, how about an XSL example? :) Does every page need to have its own XSL, or can I still build JSP pages the way I do now, which is, every JSP page includes a HEADER.INC file, and a FOOTER.INC. In the header include, I have lots of scriplet code that displays a "consistent" graphical menu bar at the top of every page, with the ability to change the actual image depending on any number of circumstances. Also, the login menu, some dynamic text and so on is displayed based on any number of circumstances as well. Ideally, what I am after is the ability to allow the end user to "customize" the way the site looks. Instead of the menu bar at top, maybe they want it on the side. So the XSL would basically somehow use two frames, one on the left and the big one on the right for content. Maybe they want the footer on the bottom to never disappear, the menu bar at the top to never disappear, and the content in the middle to be scrollable, so that no matter what page they go to, the top and bottom stuff never changes..only the content. Some may like to see their name displayed, some may not. Some may want their name in RED ARIAL, some may want it in yellow Times, and so on. I know a number of these things can be done pretty easily in JSP (I have done it), but I would like the ability to use XSLT to also render WML and HTML, as well as "text" only all with the same given data. I have seen a site use XSL/XSLT for just this purpose. Incidentally..do you have any example URLs that I can look at..to see what XSL output has done for your site?

Re: Re[2]: xml,xsl in orion
Instead of opening a HTTP connection to get the XML content from the JSP, wouldn't be possible to execute the JSP directly from the servlet doing something similar to what jsp:include does? Maybe If you hand your own HttpServletResponse implementation out to the RequestDispatcher.forward method you could achieve this? Any thoughts? This is important if you want your xml producer to be able to see any request parameters (as well as having access to the user environment - user session, application, etc)...

RE: Re[2]: xml,xsl in orion
Kevin, Here is a simpler way to do this: 1) request comes to controller servlet. 2) controller makes url connection and get content from xml producing jsp. 3) controller then gets xsl from any other location (file, jsp, or db) 4) controller hands xml, and xsl to xalan directly (no servlet here) for processing. 5) controller returns transformed xml(wml,pdf,html,xhtml, ..whatever) I do this all the time, and it works fabulously. I fact one app I wrote uses dynamic xsl generated from a jsp. Very cool. Cheers!

RE: Re[2]: xml,xsl in orion
If you don't mind I would like to ask you a question or two.. How exactly is the XSL, XML output of a JSP (using text/xml) being passed to the XSLT engine (servlet I assume), and then how is your code returning the HTML output back to the browser? I assume you do something like so (in psuedo code): 1) Request comes in to servlet 2) Servlet makes a URL connection to a JSP page 3) JSP output sent to servlet in XML format 4) Servlet then loads XSL text 5) Servlet calls upon another servlet (XSLT Servlet) passing to it the xml output of the JSP page and the xsl it loaded. 6) The return (in a response I assume) is the HTML output from the servlet that rendered the xml and xsl into html 7) The servlet then sends this response back to the browser. IS that the general idea? Or is there some other way of doing this? I would assume rather than loading the xsl, it tells the XSLT engine the path/filename of the xsl text and that engine loads it.

We are currently working with this exact procedure, and you are correct Manoj, the transformation (XSLT) happens server-side and HTML is just fed to the clients browser. We are using the XSLTServlet that used to exist on the old OrionSupport site.. I don't believe it is available there anymore. There was problems with Orion's xslt servlet.. (may be fixed now)... also we are using SAXON to do the XSLT Transformations (called from the XSLTServlet)... Does anyone know what came of this servlet? Is it still supported? Being updated? I notice that there are issues with using it with the latest version of Saxon (5.5.1)... Anyway Orion's implementation of the XSLServlet worked.. but had some limitations with the xsl:param element. If you look in your global-web-application.xml you'll see something like the following : And also a little later... something like : xsl com.evermind.servlet.XSLServlet defaultContentType text/html This performs servlet chaining... so when your JSP produces an XML document with content type text/xml... the servlet-chaining within Orion captures it and passes it to the XSL servlet... which process it.. produces HTML and displays HTML to the end-user. What version of Orion are you using? 1.3.8 is our current development version and the described process is working for us. Dylan Parker Feel free to ask me more questions.
