Xmlgen and java version

Question

trying to figure out which jars need to be in my classpath.
Using 1.4.2 I get
911@file:/C:/sgml/NISO/2005/05Std/dtbook121a.dtd
generating document #1
Exception in thread "main" java.lang.NoClassDefFoundError: org/w3c/dom/ranges/Do
cumentRange
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:539)
at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:12
3)
etc,
with 1.5 I get
Exception in thread "main" java.lang.NullPointerException
at com.sun.msv.generator.DOM2toSAX2.convertAttributes(Unknown Source)
at com.sun.msv.generator.DOM2toSAX2.onElement(Unknown Source)
at com.sun.msv.generator.DOM2toSAX2.traverse(Unknown Source)
at com.sun.msv.generator.Driver.run(Unknown Source)
at com.sun.msv.generator.Driver.main(Unknown Source)
1. Which jars are needed please?
I currently have
set x=/myjava/xmlgen
set cp=%x%/xmlgen.jar;%x%/msv.jar;%x%/xerces.jar;%x%/xercesImpl.jar
2. Which version of java has it been proven with please?
TIA, DaveP

Answer 1

Further information.
Using the provided xerces.jar, recent xmlParserAPIs.jar and java 1.4.2
the error reduces to
java -cp /myjava/xmlgen/xmlgen.jar;/myjava/xmlgen/xmlParserAPIs.jar com.sun.msv.generator.Driver -dtd dtbook121b.dtd -root {}book
parsing a grammar: dtbook121b.dtd
