Examples of org.xmldb.api.base.XMLDBException

org.xmldb.api.base.XMLDBException
XMLDBException is thrown for all errors in the XML:DB API. It contains two error codes one an XML:DB error code as defined in ErrorCodes and one vendor specific. If the error being thrown is only vendor specific then errorCode MUST be set to ErrorCodes.VENDOR_ERROR. @see org.xmldb.api.base.ErrorCodes
