Richfaces el-api和Tomcat7“无法解析表达式”

Question

我正在将旧的Tomcat6应用程序（JSF 1.2和RichFaces 3.3）迁移到Tomcat7。现在我收到以下错误（底部的完整堆栈跟踪）：

Sep 01, 2015 11:18:57 AM com.sun.facelets.FaceletViewHandler handleRenderException
SCHWERWIEGEND: Error Rendering View[/pages/packageComponents.xhtml]
com.sun.facelets.tag.TagAttributeException: /pagecomponents/content/packageComponentsContent.xhtml @147,108 value="#{package.cmPackageComponent.cmPackage.packageId}" Failed to parse the expression [#{package.cmPackageComponent.cmPackage.packageId}]
    at com.sun.facelets.tag.TagAttribute.getValueExpression(TagAttribute.java:259)

我认为问题是旧的应用程序使用了自己的el-api库：  而Tomcat7有自己的el-api：开箱即用，而且这两者可能存在冲突。

问题是：

• 有没有机会告诉服务器使用旧的 “el-ri.jar”而不是新的？
• 旧的“el-ri.jar”会不会 与Servlet 3.0兼容吗？
• 如何解决这个问题？

提前致谢！

PS：“-Dorg.apache.el.parser.SKIP_IDENTIFIER_CHECK = true”无法解决问题，因为未来的查询也不会有效。

据我所知，除了从tomcat的lib文件夹中删除已打包的文件夹并将其放在那里之外，我无法告诉你使用你的el jar（风险很大，很有可能它会破坏某些东西）否则在容器功能中。）

执行此操作的正确方法可能是将任何不符合要求的表达式迁移到新EL。关于具体表达，正如您已经提到的-Dorg.apache.el.parser.SKIP_IDENTIFIER_CHECK=true可以解决/解决方法。如果在应用此项后您遇到其他表达方式的困难，请分享，社区可以帮助那里。
