ERROR: 'Could not compile stylesheet' FATAL ERROR: 'java.lang.NullPointerException'

Question

Apologies as i know this question has been asked before but i've tried doing what was said with still no luck. I am getting this error everytime:

java.lang.NullPointerException
at test.XSLTransformer.main(XSLTransformer.java:35)
ERROR:  'Could not compile stylesheet'
FATAL ERROR:  'java.lang.NullPointerException'

It is not clear how your XSLT code looks but you have tagged the question as XSLT 2.0 while the classes in the stack trace, like `com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl`, suggest you are using the built-in Xalan XSLT 1.0 processor. So perhaps Xalan just can't compile your XSLT code as it is not XSLT 1 but rather XSLT 2, for which in the Java world you would need to use Saxon 9 (or I think in the IBM Websphere world, a package specific to that environment). — Martin Honnen, Feb 13 '20 at 07:20
