xep-support: RE: [xep-support] Servlet Connector issue

Actually I think I have a better solution now:

        TransformerFactory tf = new com.icl.saxon.TransformerFactoryImpl();
        Transformer trns = tf.newTransformer(style);
        FOTransformer transformer = new FOTransformer(trns,xep);

The advantage is that the System properties are left alone for other
applications running in the same JVM.

Cheers,
Morten

Hi Khachik,
That worked like a charm, thanks a lot!
The solution was to keep xep.jar at the end of the WebLogic classpath, and
add the line of code mentioned below to my servlet.
Cheers,
Morten

Hello,

add the following to your code, before calling the transformer:
System.setProperty("javax.xml.transform.TransformerFactory",
"com.icl.saxon.TransformerFactoryImpl");

This will set saxon as an explicit transformer.

Best Regards,
Khachik
