I've added some code for local resolving of entities to the optional
XMLValidateTask. Following is an example, how to use it:
<xmlvalidate failonerror="false" lenient="false" warn="true">
<fileset dir="${etc}" includes="*.xml"/>
<dtd publicId="-//DCTSS//DTD service//EN"
location="${lib}/dtd/service_1_0.dtd"/>
<dtd publicId="-//DCTSS//DTD juna-service//EN"
location="${lib}/dtd/juna-service_1_0.dtd"/>
<dtd publicId="-//Sun Microsystems, Inc.//DTD J2EE Client 1.2//EN"
location="${lib}/dtd/application-client_1_2.dtd"/>
<dtd publicId="-//DCTSS//DTD juna-client//EN"
location="${lib}/dtd/juna-client_1_0.dtd"/>
</xmlvalidate>
I'de love committing it myself, but I don't have write access to the
repository ..
