java.lang.Object

All Implemented Interfaces:

MuleContextAware, Initialisable, Filter

public class JsonSchemaValidationFilter
extends SchemaValidationFilter
implements MuleContextAware

Validate a JSON string against an XML schema. Note: Ideally, this would call the Validator using STAX. Unfortunately, 1. xalan.jar is needed to avoid bugs in the version of Xalan built into the JRE 2. Xalan does not work with STAX 3. Having Xalan in the classpath overrides the default (STAX-compliant) factories for transformations, validators, etc with ones that aren't STAX-compliant The result is that, while the ideal would be to implement this class by validating a STAXSource, that won't be possible until either we can assume a JRE with bith STAX and a working Xalan fork, or there';s a xalan.jar that supports StAX.
