Jboss 7.1 Seam 2.2.1 JSF 1.2项目环境中的javax.servlet.ServletException

Question

我们已经使用Jboss 7.1 + Seam 2.2.1.Final + JSF 1.2 + Richfaces 3.3.3.Final和JBoss Maven Integration 1.0开发了一个Web应用程序。 我们已成功将.war文件部署到应用程序服务器。 但是，一个动作完成后，我们希望对.xhtml页面之一进行重定向操作。 但是浏览器抛出以下异常。 我们已经调试了代码，似乎异常发生在接缝的响应阶段。 此外，没有任何导致此异常的原因，因此我们无法得出该异常的主要原因。 有谁有主意吗？

我使用此链接http://lucasterdev.altervista.org/wordpress/2011/06/14/working-with-seam-2-2-and-jboss-as-6/解决了问题

作为记录：在您的Web项目的pom.xml中，将servlet-api和jboss-seam-jul工件从jboss-seam-ui依赖项中排除，如以下代码片段所示：

<dependency>
    <groupId>org.jboss.seam</groupId>
    <artifactId>jboss-seam-ui</artifactId>
    <version>${seam.version}</version>
    <exclusions>
        <exclusion>
            <artifactId>servlet-api</artifactId>
            <groupId>javax.servlet</groupId>
        </exclusion>
        <exclusion>
            <groupId>org.jboss.seam</groupId>
            <artifactId>jboss-seam-jul</artifactId>
        </exclusion>
    </exclusions>
</dependency>
