[oXygen-user] Problems in Ant transform, xslt task and manually specified TransformerFactory

[Jirka Kosek]

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.

Thanks,

Jirka

Hi Jirka,

The ANT process started by Oxygen for an ANT transformation scenario is
a separate process and does not use the Oxygen available libraries or
class loaders.

But if you edit the ANT transformation scenario, in the "Options" tab
you have a "Libraries" button which you can use to add additional
libraries to the started process class path. You can add for example the
Saxon 6 libraries which come in the Oxygen installation "lib "directory.

In your case I also see you have a classpath reference in the <xslt>

<classpath location="${saxon9.jar}"/>

In the ANT scenario edit dialog, in the "Parameters" tab did you set a
value for the "saxon9.jar" parameter name?

Regards,
Radu

I see, but there are still some strange things happening because Ant run
from oXygen behaves slightly differently then when invoked from
command-line. But I'm using standalone ant from command line, not one
bundled with oXygen (but same version 1.8.2).

Thanks, I was hoping that it will be possible to make it work without
it. But adding libraries this way solved problem.

Sure, I was just extracting snippet from more complex build.xml.
Property is correctly set.

Anyway thanks,

Hi Jirka,

Basically the "ant.bat" usually has some class paths and parameters
specified before starting the ANT process.
As the Oxygen ANT transformation scenario starts the Java process
directly all these settings need somehow to be added as options to the
ANT scenario.

So yes, there are differences, Oxygen does not start ANT by invoking the
"ant.bat" executable.

Radu
