Alex, Here are two examples. I would expect loadClasspathResource to find this first one using the sysid. However, it isn't in the jar as just wxBase.xsd. It is in myAppPrefix/OGC/int/eurocontrol/wx/1.1.0. I noticed there's an extra .0 there that isn't in the pub. I put a version of the file with a path of myAppPrefix/OGC/int/eurocontrol/wx/1.1 as well, but that doesn't help either. 2009-10-28 15:17:51,156 DEBUG [org.jboss.ws.core.utils.JBossWSEntityResolver] resolveEntity: [pub=http://www.eurocontrol.int/wx/1.1,sysid=wxBase.xsd] 2009-10-28 15:17:51,156 TRACE [org.jboss.util.xml.JBossEntityResolver] resolvePublicID, publicId=http://www.eurocontrol.int/wx/1.1 2009-10-28 15:17:51,156 TRACE [org.jboss.util.xml.JBossEntityResolver] resolveSystemID, systemId=wxBase.xsd 2009-10-28 15:17:51,156 TRACE [org.jboss.util.xml.JBossEntityResolver] resolveClasspathName, systemId=wxBase.xsd 2009-10-28 15:17:51,156 TRACE [org.jboss.util.xml.JBossEntityResolver] Mapped systemId to filename: wxBase.xsd 2009-10-28 15:17:51,156 TRACE [org.jboss.util.xml.JBossEntityResolver] resolveSystemIDasURL, systemId=wxBase.xsd 2009-10-28 15:17:51,156 TRACE [org.jboss.util.xml.JBossEntityResolver] Trying to resolve systemId as a URL 2009-10-28 15:17:51,156 TRACE [org.jboss.util.xml.JBossEntityResolver] SystemId is not a url: wxBase.xsd java.net.MalformedURLException: no protocol: wxBase.xsd at java.net.URL.(URL.java:567) at java.net.URL.(URL.java:464) at java.net.URL.(URL.java:413) at org.jboss.util.xml.JBossEntityResolver.resolveSystemIDasURL(JBossEntityResolver.java:403) at org.jboss.util.xml.JBossEntityResolver.resolveEntity(JBossEntityResolver.java:266) at org.jboss.ws.core.utils.JBossWSEntityResolver.resolveEntity(JBossWSEntityResolver.java:65) at org.jboss.ws.metadata.wsdl.xmlschema.JBossXSEntityResolver.resolveEntity(JBossXSEntityResolver.java:79) at org.apache.xerces.impl.XMLEntityManager.resolveEntity(Unknown Source) at org.apache.xerces.impl.xs.XMLSchemaLoader.resolveDocument(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDHandler.resolveSchema(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDHandler.constructTrees(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDHandler.parseSchema(Unknown Source) at org.apache.xerces.impl.xs.XMLSchemaLoader.loadSchema(Unknown Source) at org.apache.xerces.impl.xs.XMLSchemaLoader.loadGrammar(Unknown Source) at org.jboss.ws.tools.JavaToXSD.parseSchema(JavaToXSD.java:182) at org.jboss.ws.tools.wsdl.WSDL11Reader.processTypes(WSDL11Reader.java:401) at org.jboss.ws.tools.wsdl.WSDL11Reader.processDefinition(WSDL11Reader.java:178) at org.jboss.ws.tools.wsdl.WSDLDefinitionsFactory.parse(WSDLDefinitionsFactory.java:128) at org.jboss.ws.metadata.umdm.ServiceMetaData.getWsdlDefinitions(ServiceMetaData.java:295) at org.jboss.ws.metadata.builder.jaxws.JAXWSClientMetaDataBuilder.buildMetaData(JAXWSClientMetaDataBuilder.java:86) at org.jboss.ws.core.jaxws.spi.ServiceDelegateImpl.(ServiceDelegateImpl.java:140) at org.jboss.ws.core.jaxws.spi.ProviderImpl.createServiceDelegate(ProviderImpl.java:64) at javax.xml.ws.Service.(Service.java:81) ... 2009-10-28 15:17:51,156 DEBUG [org.jboss.util.xml.JBossEntityResolver] Cannot resolve [publicID=http://www.eurocontrol.int/wx/1.1,systemID=wxBase.xsd] 2009-10-28 15:17:51,156 DEBUG [org.jboss.ws.core.utils.JBossWSEntityResolver] Cannot resolve entity: [pub=http://www.eurocontrol.int/wx/1.1,sysid=wxBase.xsd] For completeness, I'm posting the xsd file that is causing the above: <schema targetNamespace="http://www.eurocontrol.int/wx/1.1" xmlns:wx="http://www.eurocontrol.int/wx/1.1" xmlns="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified" version="1.0"> ...
