Hi, I'm trying to migrate my Spring-based webapp from JBoss AS 4.2.3.GA to JBoss AS 5.1.0.GA. I'm running into the following on startup: Caused by: org.jboss.xb.binding.JBossXBException: Failed to parse source: Failed to parse schema for nsURI=http://www.springframework.org/schema/context, baseURI=null, schemaLocation=null Caused by: org.jboss.xb.binding.JBossXBRuntimeException: Failed to parse schema for nsURI=http://www.springframework.org/schema/context, baseURI=null, schemaLocation=null Caused by: org.jboss.xb.binding.JBossXBRuntimeException: -1:-1 1:55 White spaces are required between publicId and systemId. Would anyone here know why? This is the header of for example applicationContext.xml: <?xml version="1.0" encoding="UTF-8"?> | <beans | xmlns="http://www.springframework.org/schema/beans" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xmlns:context="http://www.springframework.org/schema/context" | xmlns:aop="http://www.springframework.org/schema/aop" | xsi:schemaLocation=" | http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd | http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd | http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"> Many thanks for your support, Nes View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4262103#...
