Hi, I have installed jaxp-1.0.1 in /usr/local/jaxp-1.0.1. I have set CLASSPATH=/usr/local/jaxp-1.0.1 in my /etc/profile file. When I type ./build.sh in the tomcat directory I get the following: Buildfile: build.xml BUILD FAILED No JAXP compliant XML parser found. See http://java.sun.com/xml for the reference implementation. --- Nested Exception --- java.lang.ClassNotFoundException: javax.xml.parsers.SAXParserFactory at org.apache.tools.ant.Main.runBuild(Main.java) at org.apache.tools.ant.Main.main(Main.java) Total time: 0 seconds Can anyone help with this, I really need to get this compiled under SCO Openserver.
