我正在將一箇舊的Tomcat6應用程序（JSF 1.2和RichFaces 3.3）遷移到Tomcat7。現在，我得到以下錯誤（在底部全堆棧跟蹤）：Richfaces el-api和Tomcat7「解析表達式失敗」
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)
我認爲問題是，舊的應用程序中使用它自己的EL-API庫： 
而Tomcat7都有自己的EL-API ：
開箱即用，而這兩者顯然有衝突。
的問題是：
- 是否有任何機會，告訴服務器使用舊 「EL-ri.jar」，而不是新的？
- 舊的「el-ri.jar」是否與兼容於Servlet 3.0？
- 任何進一步的想法如何解決這個問題？
在此先感謝！
PS：「-Dorg.apache.el.parser.SKIP_IDENTIFIER_CHECK = true」不能解決問題，因爲將來的查詢不會起作用。
