JSP include - unwanted xml attribute value display

Hello,

I have a issue with jsp include. I'm including this servlet which gives output as XML.  This XML output is something like this:

[-------]
   <ServerCpuUsage Status="normal" Value="1" />
- <FanStatus Status="normal">
  <Fan DisplayName="Fan 1" Status="normal">on</Fan>
  </FanStatus>
- <PowerSupplyStatus Status="critical">
  <PowerSupply DisplayName="Power supply 1" Status="critical">off</PowerSupply>
   </PowerSupplyStatus>
[-------]


MY JSP code:

[--------------------]
<jsp:include page="/resource/Document" /> [THIS IS SERVLET WHOSE OUTPUT IS ABOVE]
 <%  
 
         ServletContext context = getServletContext();
         Document doc1 = (Document)context.getAttribute(id+":"+ServletConstants.DOC);  
         TransformerFactory tFactory = TransformerFactory.newInstance();
         InputStream is = context.getResourceAsStream("/stylesheets_new.xsl");
         Transformer transformer = tFactory.newTransformer(new StreamSource(is));
         Source source = new DOMSource(doc1);
         transformer.transform(source, new StreamResult(out));
%>
[--------------------]

When I run my JSP, using stylesheet the output is correct, but I'm getting extra with stuff bcoz of jsp include: Like this:

OUTPUT:
===================
onoff
[correct stylesheet output.....]
===================

I dont want that "onoff" which is attribute value from <fan> and <powersupply> if you can see the XML output.
Is there any way to get rid of this "on" and "off" from attribute <fan> and <powersupply> of auto generated servlet. Do I need to replace jsp include with something else ?? Please help

Regards,

XSL is to large and u may get confuse, to make it easy, I hv copied below the xsl part which reflects the above Question. This is the XSL.

<xsl:for-each select="Inventory">

    <xsl:for-each select="ServerCpuUsage">
    <xsl:for-each select="@Value">
    <xsl:value-of select="." /> %
    </xsl:for-each>
    </xsl:for-each>

      <xsl:for-each select="Fan">
      <xsl:value-of select="@DisplayName"/>
     <xsl:value-of select="@Status"/>
     </xsl:for-each>

      <xsl:for-each select="PowerSupply">
      <xsl:value-of select="@DisplayName"/>
     <xsl:value-of select="@Status"/>
     </xsl:for-each>

</xsl:for-each>
Let me tell you XSL is has notthing to do with "onoff" display stuff. Because when I tried my JSP code below, there was no "onoff" extra display. And the stylesheet was same. Its only bcoz of change of JSP code and additing the jsp include.

My Old JSP code which displayed correctly with no extra display of "onoff" ...
<%
   String childUrl = "/resource/Document";
   StringBuffer reqURL = request.getRequestURL();
   String contextURL = reqURL.substring(0,reqURL.lastIndexOf(request.getServletPath()));    
   URL url = new URL(contextURL + childUrl );  
       
   HttpURLConnection conn = (HttpURLConnection)url.openConnection();            
   conn.setDoInput(true);                
   TransformerFactory tFactory = TransformerFactory.newInstance();
   Transformer transformer = tFactory.newTransformer( new StreamSource("stylesheets_new.xsl") );
   transformer.transform(new StreamSource(conn.getInputStream()), new StreamResult(out));
%>
Errrr...  the line:

<jsp:include page="/resource/Document" />

will put the words

    onoff

At the top of the page, as the browser will try to render the XML as HTML, so strip out all the tags (as they are not valid HTML tags), and display the results...

If you view the source of the page, the XML will be there (at the top of the page), but in the browser, it will just look like "onoff"

Why do you include an XML document into your JSP?
ie:  get rid of the line:

<jsp:include page="/resource/Document" />

:-)
hi TimYates,

Dont you think it would be easy for me to get rid of that include, I hv to include in order to run this line
" Document doc1 = (Document)context.getAttribute(id+":"+ServletConstants.DOC);" which is in JSP code.


Is the XML dumped into the page when you view source on the HTML?

what does

<jsp:include page="/resource/Document" />

actually include?
I'll explain in my own terminology.
That include,  includes the Servlet Output which gives XML.
If you dont include <jsp:include page="/resource/Document" />
this will not work as said earlier: " Document doc1 = (Document)context.getAttribute(id+":"+ServletConstants.DOC);"

Now what this doc1 has is, the DOM XML which is produce by include servlet.
Why I need doc1, bcoz transformation need, xml and stylesheet. Stylesheet file name you can see in the code above. And XML is what we getting after including the include tag and in doc1 gettting from ServletContext.

Is there any other way to replace include tag, something like <servlet name="" class=""... ???
I GOT THE ANSWER MYSELF THRU OTHER RESOURCES:

Simply replace <jsp include> code with
<SERVLET NAME="Servlet" CODE="Servlet.class" CODEBASE="url">
</SERVLET>
Cool :-)
