XML Schema validation in Talend ESB 8.0.1

Hi,

I want to use a schema validation in my talend route like this (cMessagingEndpoint)

"validator:xsd/myschema.xsd"

This works in the Talend 8 studio, but deploying it to the Talend runtime generates an error:

Blueprint Event Dispatcher: 1 | rocessor.validation.SchemaReader 186 | 144 - org.apache.camel.camel-xml-jaxp - 3.11.1 | Property 'http://javax.xml.XMLConstants/property/accessExternalDTD' is not recognized.
org.xml.sax.SAXNotRecognizedException: Property 'http://javax.xml.XMLConstants/property/accessExternalDTD' is not recognized.

The same route works in Talend 7.3.1. There I had to add a cConfig component for deployment with the following code:

//Fix for XSD bug on deployment
java.util.Map<String, String> properties = new java.util.HashMap<String, String>();
properties.put("CamelXmlValidatorAccessExternalDTD", "true");
camelContext.setProperties(properties);

How to make it work in Talend 8 ?

Regards, Marius

Hello,

Could you please try to deny reference to external schemas to see if it works?

You could set system property "javax.xml.accessExternalSchema=false" to deny references to external schemas;
System property can be set in Runtime configuration file "{runtime}/etc/system.properties"

Feel free to let us know if it helps.

Best regards

Sabrina

Hello,

Thanks for your response

Unfortunately that system property didn't work. The same error occurs.

I have added the full error in the attachment test.log

Best regards

Hi,

I just noticed that it's a warning. Not an error 😞 apologies.

Unfortunately the official support article doesn't suppress the warning.

I will also respond to that article

Best regards,

Marius

To suppress these warnings in Talend ESB 8 so that they don't fill up the tesb.log files, edit the RUNTIME-HOME/etc/org.ops4j.pax.logging.cfg file and add the following lines:

log4j2.logger.validatingProcessor.name = org.apache.camel.support.processor.validation.ValidatingProcessor log4j2.logger.validatingProcessor.level = ERROR log4j2.logger.schemaReader.name = org.apache.camel.support.processor.validation.SchemaReader log4j2.logger.schemaReader.level = ERROR
