Maven 2 Apache Commons EmailValidator和SeamListener异常（未部署）

通过Maven使用Apache Commons EmailValidator时，我遇到以下问题，无法部署我的应用程序：

Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener
java.lang.LinkageError: loader constraints violated when linking org/xml/sax/EntityResolver class

我在pom.xml中使用了以下代码：

<dependency>
 <groupId>commons-validator</groupId>
 <artifactId>commons-validator</artifactId>
 <version>1.3.1</version>
</dependency>

一个帮助？

commons-validator-1.3.1.jar工件拉取xml-api-1.0.b2.jar，如下所示：

$ mvn dependency:tree [INFO] Scanning for projects... [INFO] Searching repository for plugin with prefix: 'dependency'.

您正在使用mvn部署吗？部署是如何配置的？可能还涉及其他组件，但我在这里看不到它们，因为您没有添加POM。
