    I'm writing my own JBI component. It requires Saxon B 9.0.0.8 as XSLT engine instead the default one provided with Petals CDK. Saxon B 9.0.0.8 is required to get the feature about reflexive Java functions no more available in Saxon HE (only available in Saxon PE or EE). So I exclude Saxon from the transitive dependencies of Petals CDK and I add my own version of Saxon.

    At runtime Saxon B is not used until I replace Saxon HE provided by Petals ESB container (in $PETALS_HOME/lib) by the default XSLT engine of the JVM (renaming Saxon HE jar file, and removing system property javax.xml.transform.TransformerFactory in Petals ESB start-up script.

The problem was with petals-log bringing Saxon-HE with it.

PETALSDISTRIB-147 is the solution.

The SL is available in Maven Repository as SNAPSHOT version.

To configure the SE XSLT to use the SL, just edit the component JBI descriptor adding the tag shared-library as following:

...
   </bootstrap-class-path>
   <shared-library version="1.0-SNAPSHOT">petals-sl-saxonB-9.0.0.8</shared-library>
   <ns2:acceptor-pool-size>3</ns2:acceptor-pool-size>
   ...

Sorry and could you also provide step-to-step for configuring the XSLT SE with this SL? I'm not familiar with it

Wait a minute, I'm writing and committing it.

Sorry, seems to be on trunk as stated in PETALSESBCONT-333

And something is not clear to me, is it with the trunk version of petals or with 4.3?

This problem can be reproduced using SE XSLT:

  • Remove the Saxon jar file included in Petals SE XSLT,
  • Configure it with the shared library petals-sl-saxonB-9.0.0.8,
  • Deploy a SU containing an XSL with a reflexive Java function.
