[jboss-dev-forums] [Design of JBoss ESB] - Validation of incoming message

[viralshah72]

1. Is validating the incoming message to ESB a standard/best practice or it should not be done?
2. We are having a existing webservice exposed as a proxyservice via HTTP router. The client is calling the proxy webservice. We need to validate the incoming XML using Schema.
3. Tried using the inbuilt SchemaValidationAction 
like

		
	    

When valdiation is failing it is generating Exception which is directly getting shown on JBOSS console.
17:53:59,321 ERROR [SchemaValidationAction] SAXExcption while trying to validate against schema '/re
quest.xsd'
org.xml.sax.SAXParseException: cvc-datatype-valid.1.2.1: 'somestring' is not a valid value for 'integer'.

        at com.sun.org.apache.xerces.internal.jaxp.validation.Util.toSAXParseException(Util.java:109.....

Question is how to and where to catch this exception ? Since this is inbuilt action, when & where in the actionpipeline can we catch the validation exception so that required steps can be taken.
