Hi!
My platform is windows xp 32 bit, and right now I'm using Tomcat 7.0.2
I found a strange bug, using dom objects in JSP. Since Tomcat 6 and
higher JSP page compiler throws Exception: The method
getElementsByTagNameNS(String, String) is undefined for the type
Element. How can it be? Method getElementsByTagNameNS must be define and
it is define in Xerces Parser (last version), for example. I can use
method getElementsByTagName, instead, but problem stay... plenty of code
need to rewrite... can you help?
Log is in attachment. Source code of test JPS-page also attached.
