NoClassDefFoundError for NamespacePrefixMapper in Java 1.6

[anonymous]

Running docx4j 2.5.0 with Java 1.6 which uses its own JAXB implementation throws a NoClassDefFoundError? because com.sun.xml.bind.marshaller.NamespacePrefixMapper? is now internal.

If you are building docx4j from sources, prior to  http://dev.plutext.org/trac/docx4j/changeset/1196 you had to have both Java 6 and the JAXB reference implementation.

Since  http://dev.plutext.org/trac/docx4j/browser/trunk/docx4j/src/main/java/org/docx4j/jaxb/NamespacePrefixMapperUtils.java?rev=869 you should be able to run docx4j binaries using either the Java 6 or JAXB reference implementations.

See comment at top of  http://dev.plutext.org/trac/docx4j/browser/trunk/docx4j/src/main/java/org/docx4j/jaxb/NamespacePrefixMapperUtils.java?rev=1196 for gotchas.

I suggest you try a docx4j nightly build.

If you have any further problems, please raise them in the forum first.
