[jdom-interest] Transformation Issue

Fri Jan 19 06:34:50 PST 2007

Thanks - I'm now able to see what the difference is:

  The DOCTYPE, declared in the "xsl:output" element is produces two slightly different Strings (depending on whether I'm in Tomcat with JDK 4 or Websphere with JDK 5). The difference being whether or not there is a space between the System ID and the Public ID

  The correct version (in Tomcat):
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 

  The incorrect version (in Websphere):
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

  It looks like this was a known issue and eventually fixed(?)

  Thanks again for your help!

  Why not try to use some other output than JDOM (like a StreamResult) and then compare the output from the two configurations?
Since JDOM complains in one case but not the other, there has to be a difference.

   I'm running into a strange issue and am hoping someone here has some advice on how to best troubleshoot the problem.  

   I have a very simple XSLT operation (producing HTML), using the XSLTransformer class:

   XSLTransformer transformer = new XSLTransformer(xsl);

   Document doc2 = transformer.transform(doc);

   When I run this in a JDK 1.4 / Tomcat configuration, the Document is returned that looks exactly as I would expect it (an HTML document).  When I use the same code in a JDK 5 / WebSphere configuration, the Document object doesn't contain any elements (so when I try to display with an "toString" or "XMLOutputter", I get the following exception message: 'A DocType cannot be added after the root element').   

   My guess is that this is ultimately related to some Xalan / Transformer issue, but I'm not sure what the best way is to determine what's being used (vs. what should be used).

   Any advice is appreciated.
