The problem I am experiencing could be my misunderstanding of the DOM, objects and servlets - so I was/am looking for guidance on how to narrow the problem down, because as you can tell I am pretty clueless. - When I parse a DOM Document I put it into a variable. - Then I want to set one j2ee-servlet-container-webapp's context attribute (name=object pair that is available in the servlet container). - When I set it equal to anything other then the parsed document I get what I expect. - When I try to put the parsed document in the context attribute I always get null. Should I be able to store a parsed document in a ServletContext attribute? ----- Original Message ----- From: "Gary L Peskin" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, July 26, 2001 7:08 PM Subject: Re: xalan d7 build bug? was - Re: help - java - Basic DOM parse > Scott, Don -- > > I think Rob is talking about a problem with the documentation at > http://xml.apache.org/xalan-j/usagepatterns.html#plug > > It does state that all three files are in xalan.jar. > > Gary > > [EMAIL PROTECTED] wrote: > > > > > But when I look in the xalan.jar there is only: > > > javax.xml.transform.TransformerFactory > > > org.apache.xalan.processor.TransformerFactoryImpl > > > > I think I am confused as Edwin about your problem. > > > > I am guessing that you are expecting to see javax.xml.parsers.* stuff and > > implementation in Xalan.
