Question

我正试图从spring 2.5.6升级到Spring 3.0.5。我们正在使用josso进行单点登录。 JOSSO（1.8.2）在jboss（4.2.2）服务器lib文件夹中安装spring 2.5 libs。我们在ear lib文件夹中有spring libs，因此我们在jboss服务器库和ear libs之间存在冲突。我试图用spring 3.0.5替换jboss服务器库，但是我收到了以下错误：

任何指针，出了什么问题？

Answer 1

错误消息是：

schema_reference.4：无法读取架构文档“http://www.josso.org/schema/josso-jboss42-agent.xsd”，因为1）找不到该文档; 2）文件无法阅读; 3）文档的根元素不是。

如果使用额外的spring命名空间，在启动spring时找不到xsd，则会收到此类消息。

你可以做两件事：

1）修复网址，或

2）创建一个自己的jar文件，将xsd放入其中，并将spring.schemas文件添加到其META-INF目录中。 spring.schemas文件是一种属性文件：key是xsd url（你必须转义'：'！），值是jar中xsd文件的位置例如：

http\://www.josso.org/schema/josso-jboss42-agent.xsd=org/josso.sechma/josso-jboss42-agent.xsd

Answer 2

JOSSO XML Schema XSD存在问题。 Spring 3.0引入了严格的XML验证，因此JOSSO给出了错误。我们通过配置应用程序上下文来禁用Spring XML验证。请参阅此link。

Answer 3

我想知道JOSSO安装到JBoss的Spring JAR是否以某种方式被修改，例如添加JOSSO的Spring配置样式所需的自定义模式文件。这与堆栈跟踪一致，这表明Spring试图加载应用程序上下文并因为无法找到模式而失败。 Spring约定是将给定XML配置文件的模式文件放在JAR文件中。

查看原始Spring JAR文件，在META-INF目录中查看是否可以看到任何与JOSSO相关的模式文件。如果你这样做，那么你将不得不尝试与Spring 3 JAR一起重建相同的信息，这是一项非常重要的工作。
