[javaCompiler-users] compiles and executes but throws java exception --help

[Steven B. <dud...@gm...>]

hi
i have used JNC to compile a java app that does some xml parsing and
transformation.
my app references the javax.xml.parsers and javax.xml.transform, nothing
fancy in there.
it compiles fine but whenever i try to instantiate a SAXTransformerFactory
in my java code, i get the following error (Trs_Main is the .exe)
Exception in thread "main"
javax.xml.transform.TransformerFactoryConfigurationError:
gnu.xml.transform.TransformerFactoryImpl
at java.lang.VMThrowable.fillInStackTrace(Trs_Main.exe)
at java.lang.Throwable.<init>(Trs_Main.exe)
at javax.xml.transform.TransformerFactory.newInstance(Trs_Main.exe) // i
guess this is where the error comes from
at asy.TrsToXML.split(Trs_Main.exe)

also when i try to instantiate a SAXParserFactory object using
"SAXParserFactory factory=SAXParserFactory.newInstance();"
i get another error, probably related :
Exception in thread "main" java.lang.NoClassDefFoundError:
gnu.xml.stream.SAXParserFactory
at javax.xml.parsers.SAXParserFactory.newInstance(Trs_Main.exe)

im using jdk1.4.12

does this occur because JNC supports gnu's and not sun's SAX implementation?
please tell me what to do, do i have to use gnu's SAX in order to get it to
work?
and if so please tell me where to find it.
Thank you.
Steven
