Linux, sun's java 1.5.0_11-b03

jmat-5.0.jar contains service folder in the META-INF :

META-INF/services/javax.xml.parsers.DocumentBuilderFactory
META-INF/services/javax.xml.parsers.SAXParserFactory
META-INF/services/org.apache.xerces.xni.parser.XMLParserConfiguration
META-INF/services/org.xml.sax.driver

javax.xml.parsers.DocumentBuilderFactory contains org.apache.xerces.jaxp.DocumentBuilderFactoryImpl

That might be the source of the problem - java can not find needed classes.
Since the only thing used by NR from jmat is math for double arrays by now I just delete service directory from jmat-5.0.jar

there is no JMAT any more: it was integrated into the JMATHTOOLS Project http://jmathtools.sourceforge.net/doku.php?id=start .
The functionality NR uses is in the: JMathArray: simple linear algebra for double[][] arrays using static methods

But the it uses static methods, not objects, so it could take some time. And because of the way data saving done there will be data compatibility issues
