Subject Weird JAXP problem at Tomcat startup
Date Mon, 04 Jan 2010 17:43:04 GMT
Sometimes, when starting Tomcat I get an error when JAXP is trying to
load the DocumentBuilderFactory. Tomcat does not start completely.  This
doesn't always happen, and when it does I can restart the server and it
is fine.  I turned on JAXP debugging and noticed that when I had the
problem, JAXP was finding a system property specifying that xerces
should be used:

INFO: Starting Coyote HTTP/1.1 on http-8580
JAXP: find factoryId =javax.xml.parsers.DocumentBuilderFactory
JAXP: found system property,
value=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl

When Tomcat loads fine, it appears that system property is not set and
it is (successfully) falling back on the default:

INFO: Initializing Coyote HTTP/1.1 on http-8580
Jan 4, 2010 8:58:29 AM org.apache.catalina.startup.Catalina load
INFO: Initialization processed in 460 ms
JAXP: find factoryId =javax.xml.parsers.SAXParserFactory
JAXP: loaded from fallback value:
com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
JAXP: created new instance of class
com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl using
ClassLoader: null
Jan 4, 2010 8:58:29 AM org.apache.catalina.core.StandardService start
INFO: Starting service Catalina
Jan 4, 2010 8:58:29 AM org.apache.catalina.core.StandardEngine start
INFO: Starting Servlet Engine: Apache Tomcat/5.5.28

I have only one webapp in this instance of Tomcat.  It does have xerces
JARs in its WEB-INF/lib directory, but of course Tomcat doesn't look
there when it is loading.  I can't figure out how the system property is
being set.

I am using Tomcat 5.5.28, Java 1.6.0_07 64-bit on Oracle Linux (RHEL)
5.2.

Any help is appreciated.
