While trying to to set the pool size for an MDB I made the following discoveries. 1. The annotation is not PoolClass it is just Pool 2. Setting it from the xml is very difficult. I did as the instructions stated and I get the following stacktrace. Any ideas on how to get past this? | Caused by: org.jboss.xb.binding.JBossXBException: Failed to parse source: Failed to resolve schema nsURI= location=aop | at org.jboss.xb.binding.parser.sax.SaxJBossXBParser.parse(SaxJBossXBParser.java:203) | at org.jboss.xb.binding.UnmarshallerImpl.unmarshal(UnmarshallerImpl.java:168) | at org.jboss.deployers.vfs.spi.deployer.JBossXBDeployerHelper.parse(JBossXBDeployerHelper.java:199) | at org.jboss.deployers.vfs.spi.deployer.JBossXBDeployerHelper.parse(JBossXBDeployerHelper.java:170) | at org.jboss.deployers.vfs.spi.deployer.SchemaResolverDeployer.parse(SchemaResolverDeployer.java:132) | at org.jboss.deployers.vfs.spi.deployer.SchemaResolverDeployer.parse(SchemaResolverDeployer.java:118) | at org.jboss.deployers.vfs.spi.deployer.AbstractVFSParsingDeployer.parseAndInit(AbstractVFSParsingDeployer.java:256) | at org.jboss.deployers.vfs.spi.deployer.AbstractVFSParsingDeployer.parse(AbstractVFSParsingDeployer.java:239) | at org.jboss.deployers.spi.deployer.helpers.AbstractParsingDeployerWithOutput.createMetaData(AbstractParsingDeployerWithOutput.java:330) | ... 24 more | Caused by: org.jboss.xb.binding.JBossXBRuntimeException: Failed to resolve schema nsURI= location=aop | at org.jboss.xb.binding.sunday.unmarshalling.SundayContentHandler.startElement(SundayContentHandler.java:313) | at org.jboss.xb.binding.parser.sax.SaxJBossXBParser$DelegatingContentHandler.startElement(SaxJBossXBParser.java:401) | at org.apache.xerces.parsers.AbstractSAXParser.startElement(Unknown Source) | at org.apache.xerces.impl.xs.XMLSchemaValidator.startElement(Unknown Source) | at org.apache.xerces.xinclude.XIncludeHandler.startElement(Unknown Source) | at org.apache.xerces.impl.XMLNSDocumentScannerImpl.scanStartElement(Unknown Source) | at org.apache.xerces.impl.XMLNSDocumentScannerImpl$NSContentDispatcher.scanRootElementHook(Unknown Source) | at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source) | at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) | at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) | at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) | at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) | at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) | at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) | at org.jboss.xb.binding.parser.sax.SaxJBossXBParser.parse(SaxJBossXBParser.java:199) | ... 32 more View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4207141#...
