[remember] -I haven't no exception in servlet, just a blank page; -my isolated class test worked just fine with the output expected; [my test] -I put my classpath in my isolated class test exactly with the same classpath as tomcat gets when it starts. [result] - An exception occurred: javax.xml.transform.TransformerConfigurationException: Namespace not supported by SAXParser [why...] Why there is no exception in servlet? I just don't know!?! [What I did...] -I edited my "tomcat.sh" script I just after the definition of CLASSPATH, I redefined the CLASSPATH with xerces.jar (the one that came with xalan) in the beginning and the rest after. [what happened...] -Works ok... [conclusions...] -Why there is no exception in servlet since in any exception I write in log and I write to outputstream of response??? -What is the conflict jar of tomcat with xerces.jar, since when I use xerces it works just fine. thanks, Pedro Salazar

Doesn't getServletContext().getResourceAsStream ("/WEB-INF/classes/login.xml")); have to be getServletContext().getResourceAsStream("/login.xml")); ? - fs |+---> || Pedro Salazar| || | || | || 06/27/2001 10:34 AM | || Please respond to| || tomcat-user | || | |+---> >| | | | To: [EMAIL PROTECTED] | | cc: (bcc: Fernando Salazar/CAM/Lotus) | | Subject: SERVLET : transform XSL+XML ->OUTPUT = blank page | >| Greetings, I made a servlet where I try to produce a result to output stream of the response object that came from a transformation of XML + XSL.

SERVLET : transform XSL+XML ->OUTPUT = blank page
Greetings, I made a servlet where I try to produce a result to output stream of the response object that came from a transformation of XML + XSL. But, I just get a blank page in output...!?
