Re: velocity and JET (java emitter templates)
Sorry, I don't know anything about JET, but I was wondering if you could share with us what you have found about the two. Shinobu Kawai Yoshida [EMAIL PROTECTED] Sure thing, What I have found is that JET or Java Emitter Templates is an Eclipse technology www.eclipse.org and part of EMF (though I'm sure it could have been made a separate plugin). Similar to Velocity, JET takes templates, script and data objects and merges the three to create a final output. JET uses a JSP like scripting language. JET also allows full translation from templates to resulting output or you can compile your templates to java classes, and simply invoke the java class. If your interested in this I have found two really good tutorials on the technology which can be found at: http://www.eclipse.org/articles/Article-JET/jet_tutorial1.html and http://www.eclipse.org/articles/Article-JET2/jet_tutorial2.html I haven't really come to any conclusions other than JET is built into eclipse and supports eclipse projects. The few tests I have ran with JET have been very favorable, I didn't run into any problems with what I Was trying to do. Performance wise I have no ideas how the two compare, though the compile to class feature might be nice. ALSO I thought I'd mention that while I was researching JET I ran into another new technology that is for reporting that is being worked on called BIRT (B.I.R.T.). Business Intelligence and Reporting Tools, take a look at http://www.eclipse.org/birt/ Though thats about the extent of my knowledge at this point on it.

velocity and JET (java emitter templates)
Hi Does anyone have any any experience working with both of these template technologies? I'm evaluating both and trying to get a feel for what they can and can't do, so far I'm getting the impression that velocity provides a more flexible solution but wondering whats your experiences out there might have been with both.
JDOM and NOT using anakia ant task
Its my understanding that if I want to use Anakia it needs to be ran from an ant build script? so.. I want to execute a template against a loaded JDOM. like the following: SAXBuilder builder; Document root = null; builder = new SAXBuilder(org.apache.xerces.parsers.SAXParser ); root = builder.build( XMLFile ); //Stuff the Document (or root Element) into the context: VelocityContext context = new VelocityContext(); context.put(root, root ); /* write to file */ BufferedWriter writer = writer = new BufferedWriter( new FileWriter(./output/StartPage.html)); if ( template != null) template.merge(context, writer); BUT I am not having a whole lot of luck with it parsing my DOM correctly. I can dump my JDOM and it shows the tree correctly. but I am having problems doing simple things like getting at elements. heres an example I have the following data ?xml version=1.0 encoding=UTF-8? publish:project name=Published Items xmlns:publish=http://a/b/c; publish project foo this is foo /foo publish:link publish link 1 /publish:link publish:link publish link 2 /publish:link /publish:project I'm TRYING to get output text for publish:link but no matter what I try I can't seem to get the element. sigh.. I suspect I'm running into a namespace problem. If I try to fetch foo it works, but if I try to fetch publish:link it doesn't. Any ideas? Heres what I have tried in my script file(note the r, s, t, u, a , b, c , d is just to identify my output easier) html ... body -see what kinds of URI, or prefixes we can fetch ---br r $root.getPrefix()br s $root.getRootElement().getPrefix()br t $root.getNamespaceURI()br u $root.getRootElement().getNamespaceURI() //Works: RETURNS http://a/b/c -- now try to get stuff --- br a $root.getRootElement().getChild(foo).getText()br //WORKS: returns text of foo element Everything from here on FAILS to do anything br (I got to the point of trying everything I could think of..and nadda working)br b $root.getRootElement().getChild(publish:project, http://a/b/c;).getText()br c $root.getRootElement().getChild(publish:project, http://a/b/c;).getText()br d $root.getRootElement().getChild(project, http://a/b/c;).getText()br e $root.getRootElement().getChild(project).getText()br f $root.getRootElement().getChild(publish:link).getText()br g $root.getRootElement().getChild(link, http://a/b/c; ).getText()br h $root.getRootElement().getChild(publish:link, http://a/b/c; ).getText()br i $root.getRootElement().getChild(link, publish).getText()br j $root.getRootElement().getChild(publish:link, publish).getText()br k $root.getRootElement().getChild(link).getText()br Try to get from getChild() directly ---br l $root.getChild(publish:link).getText()br m $root.getChild(link, http://a/b/c; ).getText()br n $root.getChild(publish:link, http://a/b/c; ).getText()br o $root.getChild(link, publish).getText()br p $root.getChild(publish:link, publish).getText()br q $root.getChild(link).getText()br /body /html
Re: JDOM and NOT using anakia ant task (figured out the Namespace problem)
Ok figured out the problem. I have to get an actual namespace object and pass it, versus just passing the namespace text. I can dump my JDOM and it shows the tree correctly. but I am having problems doing simple things like getting at elements. heres an example ... I'm TRYING to get output text for publish:link but no matter what I try I can't seem to get the element. sigh.. I suspect I'm running into a namespace problem. If I try to fetch foo it works, but if I try to fetch publish:link it doesn't. Any ideas?
anakia question and possible problem
Having problems getting anakia to transform $root.getChild calls.. I have the following xml data file ?xml version=1.0 encoding=UTF-8? document foo name=waka test /foo /document And the following vsl file (marked by !!! problem is here) html head META content=text/html; charset=UTF-8 http-equiv=Content-Type/ title Main Title /title link href=mystyle.css rel=stylesheet type=text/css/ /head body img src=overview_banner.jpg/ p class=LargeTitle !-- PROBLEM IS HERE !! -- title$root.getChild(foo).getText()/title /p /body /html and finally the following java code - . SAXBuilder builder; Document root = null; builder = new SAXBuilder(org.apache.xerces.parsers.SAXParser ); root = builder.build( XMLFile ); ... //Stuff the Document (or root Element) into the context: VelocityContext context = new VelocityContext(); context.put(root, root ); Template template = null; template = Velocity.getTemplate(templateFile); . BufferedWriter writer = writer = new BufferedWriter( new FileWriter(./output/thePage.html)); if ( template != null) template.merge(context, writer); writer.flush(); writer.close(); .. -- When I execute the code and debug, I see the files get loaded and the merge, flush and close work fine. However, my output html still has the literal string $root.getChild(foo).getText() embedded in it. when I check the log I see the following message reference : template = StartPage.vsl [line 10,column 17] : $root.getChild(foo).getText() is not a valid reference. I have tried every variation of xml and $root command I can think of and they all give me the same error. The only thing that doesn't produce an error is if I just have $root. any Idea why my getChild() call isn't working? thanks for any help here... Also, anyone have any other examples of using anakia, I can only find one that comes with the SDK...bah.
