----------------------------------------

             Summary: Enterprise Feature of Saxon is Disabled in Camel 3.x versions.
                 Key: CAMEL-18492
                 URL: https://issues.apache.org/jira/browse/CAMEL-18492
             Project: Camel
          Issue Type: Bug
          Components: camel-saxon, camel-xslt
    Affects Versions: 3.0.0
            Reporter: Harish Annamalai


Hi All, 

We use Camel-Saxon for one of our product. We use Saxon Enterprise Edition 9.9.1.6. 

We are migrating our product from camel 2.x to camel 3.x (2.24 to 3.15 to be exact). 

We use a paid feature of Saxon; Invoking *External Java Functions* in XSL Transformations.

We also *Extension Functions,* which we pass to camel-xslt-saxon component. 

What we have observed in camel 3.x versions and above, In class {{{*}XsltSaxonEndpoint{*}.java}} During the registration of extension functions, at line 202, {{registerSaxonExtensionFunctions}} method of {{{*}XsltSaxonHelper{*}.java}} is called. 

 

In XsltSaxonHelper.class, the method, {{{}registerSaxonExtensionFunctions{}}}, at line 55, sets a feature of {*}XMLConstants.FEATURE_SECURE_PROCESSING{*}.

Unfortunately, Setting this Feature disables the External Java Function calls. 

We checked in Camel 2.x versions, this Feature is not set and therefore the External Java Calls work fine. 

 

We see this as a bug - The Feature *XMLConstants.FEATURE_SECURE_PROCESSING* is being introduced in 3.x and breaks a paid/Enterprise feature of Saxon.

 

Sample Code to test:

{{import javax.xml.XMLConstants;}}
{{import javax.xml.transform.Transformer;}}
{{import javax.xml.transform.TransformerException;}}
{{import javax.xml.transform.TransformerFactory;}}
{{import javax.xml.transform.stream.StreamResult;}}
{{import javax.xml.transform.stream.StreamSource;}}
{{import java.io.File;}}

{{public class SaxonTransformationTester {}}

{{ public static void main(String[] args) throws TransformerException {}}

{{ String foo_xml = "src/main/resources/in.xml"; // input xml}}
{{ String foo_xsl = "src/main/resources/transf.xml"; // input xsl}}

{{ EnterpriseTransformerFactory eef = SaxonEEConsumerFactory.getEnterpriseTransformerFactoryInstance();}}
{{ eef.getConfiguration().getConfigurationProperty(Feature.ALLOW_EXTERNAL_FUNCTIONS);}}
{{ eef.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true); //This causes External Functions to break}}
{{ eef.getConfiguration().setConfigurationProperty("http://saxon.sf.net/feature/trace-external-functions", false);}}
{{ Transformer transformer = eef.newTransformer(new StreamSource(}}
{{ new File(foo_xsl)));}}
{{ transformer.transform(new StreamSource(new File(foo_xml)),}}
{{ new StreamResult(System.out));}}

{{ }}}
{{}}}
