Re: [OT] What layer does an XSL transform belong to

[Jeff Kyser]

Thanks Simon.

One of the first difficulties I encountered was with the xsl transform
itself. I posted this (below) earlier, and didn't get any bites. See
<EARLIER POST>...</EARLIER POST> below.  I kept getting
handlePageException in PageContextImpl in later versions of
Tomcat/Resin and could only make the following work instead.
(It of course worked fine under Tomcat 4.1.10 and Struts 1.0 and
whatever else is in the production environment, but I needed to  
upgrade...
And that (new stuff) started to look a lot like code that did not  
belong on a JSP,
hence my question...

(what I have working now)

        <html:form action="/cart/ShoppingCartAction?method=process">
        <nested:define id="doc" property="xmlDoc" type="java.lang.String"/>
	<%
	    String xslFile = getServletContext().getRealPath("") +  
"/xsl/PrintShoppingCart.xsl";
	    if (doc != null && doc.trim().length() > 0) {
	        TransformerFactory tFactory =
	            TransformerFactory.newInstance();
	        Transformer transformer =
	            tFactory.newTransformer(new StreamSource(xslFile));
	        transformer.transform(new StreamSource(new StringReader(doc)),  
new StreamResult(out));
	    }
	%>
	</html:form>

Sorry, as I know this is off-topic, but been banging on
it most of the day and can't find much on the web either.
Have experienced the same basic problem on:

        Tomcat 4.1.24
        Resin 2.1.6,8,9
Can take an XML document, apply an XSL stylesheet to
it using command-line java tool:
	java org.apache.xalan.xslt.Process -IN foo.xml -XSL foo.xsl -OUT  
foo.html

that works great.

Now, I take the same libraries - xalan.jar, xml-apis.jar, put them in
my web app, and when I hit the jsp that does the same thing, I get:
----- Root Cause -----
javax.servlet.ServletException: org/apache/xalan/xslt/XSLTInputSource
        at  
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContex 
tImpl.java:536)
        at  
org.apache.jsp.BrowseCatalog_jsp._jspService(BrowseCatalog_jsp.java:130)
        at  
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:137)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)

Now, from what I can tell, XSLTInputSource is deprecated from an earlier
version of xalan.jar
So, I take the xalan.jar file from a Tomcat 4.1.10 install that *does*  
work, and
I get another lovely exception, failing to find  
org.apache.xalan.xslt.Process.getDefaultLiaison.
(or something like that...)

Can't seem to isolate this.

anybody seen this, or have any suggestions?

TIA,

-jeff
