Hello
I downloaded hyperjaxb.jar and jaxb-verification.jar and put them
under jaxb/lib, then i modified my build file according (I think)
to your sample ; when i run ant, i get a java.lang.NullPointerException
when building sources at the first line where i specify xjc :
<xjc schema="configuration_test.xsd"
package="meteorage.jobs.params.configuration" target="../gen-src">
<produces dir="../gen-src" includes="../gen-src/**/*.java" />
<arg line="-nv"/>
<arg line="-extension"/>
<arg line="-Xverification"/>
<arg line="-Xequality"/>
<arg line="-use-runtime meteorage.jobs.jaxbruntime.impl.runtime" />
</xjc>
is there a mistake, sth missing ?
some source files are generated under a folder "verification"
at the same level as "impl" ; it contains files "...Verifier.java"
definig ckeck.. methods ; in folder "impl" methods
equals(java.lang.Object obj) are generated
in files ...impl.java ; all seems ok except this NullPointerException
which prevents
from compiling sources
thanks in advance
