Synapse 1.2 XSLTMediator cannot work with Saxon in non-DOM mode

Hi guys,
   We are trying to use Synapse 1.2 using Saxon 8.9 transformer provider
(instead of Xalan) but we getting an exception when using the XSLTMediator
in stax mode.

We tried to run the Synapse 1.2 core tests setting
javax.xml.transform.TransformerFactory to
"net.sf.saxon.TransformerFactoryImpl" to see whether they will work, but the
XSLTMediatorTest fails with the same exception:

Running org.apache.synapse.mediators.transform.XSLTMediatorTest
- Fatal error occured in the XSLT transformation :
net.sf.saxon.trans.DynamicError: The SAX2 parser does not support setting
the 'namespaces' feature to true
- Error performing XSLT transformation using : xslt-key
net.sf.saxon.trans.DynamicError: The SAX2 parser does not support setting
the 'namespaces' feature to true

        at net.sf.saxon.event.Sender.sendSAXSource(Sender.java:241)
        at net.sf.saxon.event.Sender.send(Sender.java:142)
        at net.sf.saxon.event.Sender.send(Sender.java:43)

        at
org.apache.synapse.mediators.transform.XSLTMediator.mediate(XSLTMediator.java:177)
        at
org.apache.synapse.mediators.transform.XSLTMediatorTest.testTransformXSLTCustomSource(XSLTMediatorTest.java:88)

It seems that by default these tests are run using the Xalan transformer and
the problem does not appear, but if adding the system property in the Maven
surefire plugin configuration you should be able to reproduce it:

<systemProperties>
     <property>
         <name>javax.xml.transform.TransformerFactory</name>
         <value>net.sf.saxon.TransformerFactoryImpl</value>
     </property>
</systemProperties>

The problem seems to be that when configuring the parser (which in stax mode
seems to be an instance of
org.springframework.xml.stream.StaxStreamXmlReader), Saxon is trying to set
the following features:

- http://xml.org/sax/features/namespaces
- http://xml.org/sax/features/namespace-prefixes

Unfortunately Spring's StaxStreamXmlReader always throws a
SAXNotRecognizedException in its setFeature method:

See the javadocs:
http://static.springframework.org/spring-ws/sites/1.5/apidocs/org/springframework/xml/stream/AbstractStaxXmlReader.html#setFeature(java.lang.String,%20boolean)

Hi Andreas,
   Thanks, I tried the trunk and it works fine with Saxon, the new
SourceBuilder functionality looks great, I'm glad to see that you removed
the Spring dependency from the core module, it was causing inconsistency
with Axis2 since they use Spring 2.5.1.

Regards,
   Detelin

Detelin,

The XSLT integration has been completely reworked after the 1.2
release. If you look at the unit tests in trunk, you will see that we
now fully support Xalan and Saxon.
