setFullSchemaChecking

public void setFullSchemaChecking(boolean fullSchemaChecking)

Enable full schema grammar constraint checking, including checking which may be time-consuming or memory intensive. Currently, particle unique attribution constraint checking and particle derivation restriction checking are controlled by this option.

see property http://apache.org/xml/features/validation/schema-full-checking

Default value

false

setThrowException

public void setThrowException(boolean throwException)

Should the XmlValidator throw a PipeRunexception on a validation error. If not, a forward with name 'failure' must be defined.

Default value

false

setReasonSessionKey

public void setReasonSessionKey(String reasonSessionKey)

If set: key of session variable to store reasons of mis-validation in

Default value

failureReason

setXmlReasonSessionKey

public void setXmlReasonSessionKey(String xmlReasonSessionKey)

Like reasonSessionKey but stores reasons in xml format and more extensive

Default value

xmlFailureReason

setValidateFile

public void setValidateFile(boolean b)

If set true, the input is assumed to be the name of the file to be validated. Otherwise the input itself is validated

Default value

false

setCharset

public void setCharset(String string)

Characterset used for reading file, only used when validateFile is true

Default value

utf-8

setWarn

public void setWarn(boolean warn)

If set true, send warnings to logging and console about syntax problems in the configured schema('s). Alternatively, warnings can be switched off using suppression properties , and

Default value

true

setIgnoreUnknownNamespaces

public void setIgnoreUnknownNamespaces(Boolean b)

Ignore namespaces in the input message which are unknown

Default value

true when schema or noNamespaceSchemaLocation is used, false otherwise

setIgnoreCaching

public void setIgnoreCaching(boolean ignoreCaching)

If set true, the number for caching validators in appConstants is ignored and no caching is done (for this validator only)

Default value

false

setXmlSchemaVersion

public void setXmlSchemaVersion(String xmlSchemaVersion)

If set to 1.0, Xerces's previous XML Schema factory will be used, which would make all XSD 1.1 features illegal. The default behaviour can also be set with xsd.processor.version property.

Default value

1.1
