Hi, I have Ant build file which works perfectly outside oXygen. For various reasons both Saxon9 and Saxon6 has to be called during the build process, so xslt task always specifies which transformer to use using factory: <xslt ...> <factory name="net.sf.saxon.TransformerFactoryImpl"> <attribute name="http://saxon.sf.net/feature/xinclude-aware" value="true"/> </factory> <classpath location="${saxon9.jar}"/> </xslt> or <xslt ...> <factory name="com.icl.saxon.TransformerFactoryImpl"/> <classpath> <pathelement location="${saxon.jar}"/> </classpath> </xslt> Problem is that in oXygen (12.2, Windows/Linux) such Ant task produces the following error message: BUILD FAILED .....\build.xml:126: java.lang.ClassNotFoundException: com.icl.saxon.TransformerFactoryImpl I suppose that's because oXygen uses special classloader. Do you have any idea how to overcome this issue? I need to run same Ant script from oXygen and standalone as well.
