环境：JDK1.6+JBoss5.1.0+Struts2.1.8+Spring2.5.6+Hibernate3.3.2

将war包放入“JBOSS安装目录/server/default/deploy”目录，直接启动，报如下错误：
view plain
1. 09:24:46,890?ERROR?[JBossContextConfig]?XML?error?parsing:?context.xml??
2. org.jboss.xb.binding.JBossXBRuntimeException:?Failed?to?create?a?new?SAX?parser??
3. ????????at?org.jboss.xb.binding.UnmarshallerFactory$UnmarshallerFactoryImpl.newUnmarshaller(UnmarshallerFactory.java:100)??

分析可能与JBoss4.2.3版本类似，存在classloader问题，参考JBoss社区资料（http://community.jboss.org/wiki/classloadingconfiguration），设置Web应用加载时使用JBoss统一的classloader。具体操作方法为：在WEB-INF下增加jboss-web.xml：
view plain
1. <!DOCTYPE?jboss-web?PUBLIC?"-//JBoss//DTD?Web?Application?5.0//EN"?"http://www.jboss.org/j2ee/dtd/jboss-web_5_0.dtd">????
2. <jboss-web>????
3. ????<class-loading?java2ClassLoadingCompliance="true">??
4. ????????<loader-repository>??
5. ????????????com.example:archive=?unique-archive-name??
6. ????????????<loader-repository-config>??
7. ????????????????java2ParentDelegation=true??
8. ????????????</loader-repository-config>??
9. ????????</loader-repository>??
10. ????</class-loading>??
11. </jboss-web>??

??? 说明：com.example:archive=unique-archive-name代表jar仓库的对象名objectName?，其中,com.example可以随意取，unique-archive-name?就用部署包的名字即可，例如com.example:archive=demo.war，保证这一串唯一即可。
??? 详细说明可以通过google搜索“JBoss类隔离”。重启JBoss，上述错误不再出现，但又报如下错误：
view plain
1. 14:24:15,406?ERROR?[ContextLoader]?Context?initialization?failed??
2. org.springframework.beans.factory.BeanDefinitionStoreException:?I/O?failure?during?classpath?scanning;?nested?exception?is?java.io.FileNotFoundException:?C:/JavaPro/jboss-5.1.0.GA/server/default/deploy/demo.war/WEB-INF/lib/demo.jar/com/demo?(系统找不到指定的路径。)??

参考https://jira.springframework.org/browse/SPR-5120，下载jboss-as-sprint-int-5.0.0.GA.jar和jboss-spring-int-vfs.jar，拷贝至Web应用的lib下，修改web.xml，加入：
view plain
1. <context-param>??
2. ?<param-name>contextClass</param-name>??
3. ?<param-value>org.jboss.spring.vfs.context.VFSXmlWebApplicationContext</param-value>??
4. </context-param>??
重新启动，上述错误不再出现，但报如下错误：
view plain
1. 14:42:49,484?ERROR?[ContextLoader]?Context?initialization?failed??
2. org.springframework.beans.factory.parsing.BeanDefinitionParsingException:?Configuration?problem:?Invalid?relative?resource?location?[applicationContext-hibernate.xml]?to?import?bean?definitions?from?Offending?resource:?FileHandler@21170058[path=demo.war/WEB-INF/classes/spring/applicationContext.xml?context=file:/C:/JavaPro/jboss-5.1.0.GA/server/default/deploy/?real=file:/C:/JavaPro/jboss-5.1.0.GA/server/default/deploy/demo.war/WEB-INF/classes/spring/applicationContext.xml];?nested?exception?is?java.io.IOException:?Error?listing?files:?C:/JavaPro/jboss-5.1.0.GA/server/default/deploy/demo.war/WEB-INF/classes/spring/applicationContext.xml??

4. Caused?by:?java.io.IOException:?Error?listing?files:?C:/JavaPro/jboss-5.1.0.GA/server/default/deploy/demo.war/WEB-INF/classes/spring/applicationContext.xml??

修改spring的配置中类似?<import resource="applicationContext-xxx.xml"/>?的内容，改成<import resource="classpath:applicationContext-xxx.xml"/>。我的demo中spring配置文件在classes的spring文件夹下，因此，应该改成：<import resource="classpath:spring/applicationContext-xxx.xml"/>重新启动，不再报任何错误，访问首页正确显示，并能登录成功。
