RE: File:New generates error

Thanks lot for pointing me in right direction. In the code base system
property for transformation factory is set to "null" that's why processor uses
sun's transformation packages(XSLTC) instead of saxon which gives error. I
realized that com.sun.org.apache.xalan.internal.xsltc.compiler.Variable
present in rt.jar which is part of JDK. This does not occur always, becos the
part of code setting system property for transformation factory to null is
executed in *Some* conditions.
