Re: Struts and XSL ?
I don't have a particular framework or extension to recommend, but I will add
that XSLT and JSP can happily be used *together*. JSP is not just HTML.
Depending on what you want to do, you can easily use JSTL to do XSLT:
%-- xslt is a scoped variable of type String, Reader or
javax.xml.transform.Source --%
x:transform xslt=${xslt}
%-- dynamically generated XML here --%
/x:transform
Or many other possibilites...

RE: Struts and XSL ?
I believe the point Kris was trying to make is that, in addition to using JSP to dynamically generate HTML, you can also use JSP to dynamically generate your XSLT stylesheets.

Re: Re: Struts XML - XSL
I am trying to explain as to what exactly do I want to achieve: We are developing an HTML front-end application. But some of our screens require to interact with certain electronic devices. We shall achieve that with the help Java Swing at the Client side. This leads to the fact that some screens may be required both in HTML and Java Swing. We wish that same framework at the backend could be used for this purpose. What I want to discuss here is that how to use struts to generate an HTML and XML both, depending upon type of user. ( Not how will I send the generated XML to Swing through Socket or instead use RMI etc etc). You are right in saying that javaworld has published a good solution, and I sent a link to that approach in my first mail. What I am loking for is that craig said they shall discuss this in developer's forum to develop such a feature in struts. Has this been developed in sturts ? In that mail Craig has suggested number of approaches, the one we liked most is Quote Write a custom tag that you would use to surround all the rest of your JSP page (which would then presumably be generating XML instead of HTML). The nested text would then be passed through an XSL stylesheet specified as an attribute; something like this: struts:xsl stylesheet=x.xsl ... original body of your JSP page ... /struts:xsl This approach has the disadvantage of requiring you to modify every JSP page to include the surrounding tag, but it would be fairly easy to implement. There is a similar tag in the jakarta-taglibs xsl library that we can use as a starting point.

RE: Struts - XML - XSL
Following are the procedures that can used to apply the style sheet
Once we have already parsed the XML document, the getDocument method from
the parser instance (e.g. DOMParser) should return an object of type
Document (which is actually a DOM representation of the XML). This will be
the starting point.
To apply the XSLT transformation, you perform the following steps:
1. Create a DOMSource object and implicitly cast it to a SAX InputSource
object. The constructor takes in the Document object as a parameter.
InputSource source = new DOMSource(document);
2. Instantiate a StyleGenerator object and pass the fully-qualified class
names of the XML and XSL parsers you want to use.
StyleGenerator stylegen = new StyleGenerator(Consts.SOURCEDOC_PARSER,
Consts.STYLESHEET_PARSER);
Where:
SOURCEDOC_PARSERcom.sengen.utils.DOMParserExtension
STYLESHEET_PARSER org.apache.xerces.parsers.SAXParser
You can plug-in any DOM / SAX compliant parser you like. In this case we are
using two different parsers: a DOM parser for the XML and a SAX parser for
the XSL. The setup does not have to be this way. This is also the reason why
we have to implicitly casting in step one.
3. Lastly, call the StyleGenerator's applyStylesheet method. Originally, it
only deals with filenames but I overloaded it to accomodate InputSource and
streams. The resulting or transformed XML document is either written to a
file or returned as a byte stream.
public void applyStylesheet(String sourceFileName, String styleFileName,
String outputFileName) throws Exception
public ByteArrayOutputStream applyStylesheet(String sourceFileName, String
styleFileName) throws Exception
public void applyStylesheet(InputSource sourceInput, String styleFileName,
String outputFileName) throws Exception
public ByteArrayOutputStream applyStylesheet(InputSource sourceInput, String
styleFileName) throws Exception
Where:
sourceFileName XML filename
styleFileName XSL filename **
outputFileName filename of the resulting (transformed) XML
sourceInput InputSource object created in step 1
** any type of stylesheet like XSL-2-HTML, XSL-2-FO, XSL-2-whatever
-lines 3 and 4 correspond to steps 1 and 2 above.
-In line 7, he used the fourth version of the applyStylesheet method and
converted the byte array to a
string. This string is now the HTML transformation of the XML document.
1. public String getPresentation() {
2.
3. InputSource source = new DOMSource(getDocument());
4. StyleGenerator stylegen = new
StyleGenerator(KmpPdfgenConsts.SOURCEDOC_PARSER,KmpPdfgenConsts.STYLESHEET_P
ARSER);
5.
6. try {
7. return
stylegen.applyStylesheet(source,getStylesheet()).toString();
8. } catch(Exception e){
9. //
10. }
11.
12. return ;
13. }
Hope this helps.

know how to call the transformation of the XML data with a XSL file to
build my final html layout.
Can you help me ?

re: Struts - XML - XSL
Hi, I don't know if this is what you are looking for but I just purchased a book from Orielly press that deals with Java and XSLT: http://www.oreilly.com/catalog/javaxslt/ I don't know how I can implement this with Struts. Hope this is helpful. Alex
RE: Struts XML/XSL
Yes, We are using XSL as our output format instead of JSP. Here's what we've done: 1) We created a "Message" object that is an ActionForm. All of our ActionForms inherit from this object. This way we enforce that the "Message" object is present for each action and is either in session or request scope and we get all the functionality of Struts' ActionForms. The message object encapsulates and enforces our XML Source Document format. The source document is rendered as a DOM within this object and is used as the source for the XSLT transform. An action's data is copied into this DOM as it is created. 2) We have one JSP that all actions forward to. This JSP contains the XSLT Processor. The JSP pulls the source doc out of the Message object, sucks in the XSL file off the disk, performs the transform and spits out HTML. Advantages - 1) Flexibility. Our clients (or page designers) could write their own pages if they know XSL. They don't have to know Java or JSP or understand our beans or anything like that. We tell them our source doc format and they go off and write pages. We could also support JSP in a combined environment if need be. 2) Productivity. Not having written any JSP tags, I'm not really in a position to say this, but it seems that XSL templates are a lot easier to write than custom tags. And they accomplish most of the same purposes, at least within what we do. Before XSL, we used to write a load of Java scriptlets in our JSP, and XSL works a lot better for us. Plus you can test it in a static environment without the web server running. That's harder to do in JSP. Issues --- 1) Performance. It seems to take longer for the XSLT processor to run than the JSP "processor". We cache our pages so that it works similarly to the JSP compiler. If all of your page data is not in XML you have to DOMify it or otherwise get it into XML before running your page. This can cause performance hits as well. 2) Design. Perhaps the "Message" object could be better designed. It is really only needed at request scope, but since it is an ActionForm, it is usually held at session scope. So it has to be reinitialized on every request to keep stale data out. Maybe it would work better if it was some sort of static thing, or something that was stored in the request to be made available to the JSP. 3) Perhaps the biggest disadvantage in the way we've implemented it is deviation from the Struts architecture. When using Struts the way it was designed you have access to all the custom tags, automatic form population, and other things that we had to try to create on our own. Conclusion --- For us it's worked out well. Our data comes from the backend in XML so it makes sense to leave it there and use XSL to transform it. It also allows us to be very flexible in how we develop our pages and interact with other apps. Performance could be better, but we have yet to test it in a real environment. That will come soon. If we could do it all again (and I'm sure we will eventually) we'd probably make some tweaks in the design, but my opinion is that you can make Struts work very well with XSLT, even if you have to make some extensions to the system to do it right. Hope that helps. Greg -Original Message- From: [EMAIL PROTECTED] Sent: Tuesday, April 03, 2001 12:22 PM To: [EMAIL PROTECTED] Subject: Struts XML/XSL Has any one integrated struts with XML/Xsl?

Re: struts and XSL
[EMAIL PROTECTED] wrote: There are many competing technologies to embrace the Model 2 pattern. I get the feeling that XML/XSL and Struts are mutually exclusive. Is this a valid concern ?? I'm not sure that they are mutually exclusive, but there is a choice you ned to make for the "outermost" controlling architecture for your web application. If your application is primarily content publishing, with data based primarly in XML, you owe it to yourself to consider a framework like Cocoon, which is aimed at precisely this type of environment. That doesn't prohibit you from using the Struts custom tag library (if your presentation is in JSP pages), but you probably will not need the Struts controller environment. If your application is primarily a dynamic business app, you owe it to yourself to consider the controller framework inside Struts. This doesn't prohibit you from using XML, XSLT, and XSP -- you can still use them to create portions of the content of your pages -- but you probably will not need the Cocoon site map capabilities.
