[jboss-as7-dev] Question about Async logging

I have looked over the JBoss logging XSD, and believe I have configured asynchronous logging correctly, but I'm getting a parse error. Here is my configuration: <subsystem xmlns="urn:jboss:domain:logging:1.0"> <periodic-rotating-file-handler name="FILE" autoflush="true"> <level name="INFO"/> <formatter> <pattern-formatter pattern="%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%E%n"/> </formatter> <file relative-to="jboss.server.log.dir" path="server.log"/> <suffix value=".yyyy-MM-dd"/> </periodic-rotating-file-handler> <async-handler name="ASYNC"> <level name="INFO"/> <queue-length>1024</queue-length> <overflow-action>block</overflow-action> <subhandlers>FILE</subhandlers> </async-handler> <logger category="com.arjuna"> <level name="WARN"/> </logger> <logger category="org.apache.tomcat.util.modeler"> <level name="WARN"/> </logger> <logger category="sun.rmi"> <level name="WARN"/> </logger> <root-logger> <level name="INFO"/> <handlers> <handler name="ASYNC"/> </handlers> </root-logger> </subsystem> Here is the exception: Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[51,13] Message: Missing required attribute(s): FILE_NAME at org.jboss.as.controller.parsing.ParseUtils.missingRequired(ParseUtils.java:115) at org.jboss.as.logging.LoggingSubsystemParser.parseAsyncHandlerElement(LoggingSubsystemParser.java:259) at org.jboss.as.logging.LoggingSubsystemParser.readElement(LoggingSubsystemParser.java:149) at org.jboss.as.logging.LoggingSubsystemParser.readElement(LoggingSubsystemParser.java:84) at org.jboss.staxmapper.XMLMapperImpl.processNested(XMLMapperImpl.java:100) at org.jboss.staxmapper.XMLExtendedStreamReaderImpl.handleAny(XMLExtendedStreamReaderImpl.java:69) at org.jboss.as.controller.parsing.StandaloneXml.parseServerProfile(StandaloneXml.java:309) at org.jboss.as.controller.parsing.StandaloneXml.readServerElement(StandaloneXml.java:163) at org.jboss.as.controller.parsing.StandaloneXml.readElement(StandaloneXml.java:87) at org.jboss.as.controller.parsing.StandaloneXml.readElement(StandaloneXml.java:75) at org.jboss.staxmapper.XMLMapperImpl.processNested(XMLMapperImpl.java:100) at org.jboss.staxmapper.XMLMapperImpl.parseDocument(XMLMapperImpl.java:59) at org.jboss.as.controller.persistence.XmlConfigurationPersister.load(XmlConfigurationPersister.java:105) ... 5 more I far as I can see there is no FILE_NAME required attribute, and the line and column number it gives is the start of the async-handler tag in the configuration above. Any ideas? Thanks. Andy
