whenever I use a c:foreach tag in my jspx files I'm getting below error 

Caused by: java.lang.NoSuchMethodError: javax.servlet.jsp.PageContext.getELContext()Ljavax/el/ELContext;
    at javax.servlet.jsp.jstl.core.LoopTagSupport.unExposeVariables(LoopTagSupport.java:587)

    at org.apache.tiles.servlet.context.ServletTilesRequestContext.forward(ServletTilesRequestContext.java:241)

How can I solve this? This is only related to c:forEach. All other tags are working fine. I have follwing jar files in APP-INF/lib folder of EAR and tiles-jsp-2.2.0.jar and jstl-1.2.jar in my WEB-INF/lib of WAR file. web.xml version - 2.4

tiles-api-2.2.0 tiles-core-2.2.0 tiles-jsp-2.2.0 tiles-servlet-2.2.0 tiles-template-2.2.0

Please help, Thanks in advance

此异常表明 JSTL API 的版本比 JSTL impl 更新。事实上，Weblogic 已经捆绑了 JSTL。它显然比您的 webapp 中的版本旧。较新的 JSTL API 是从您的 webapp 加载的，但较旧的 JSTL impl 是从 Weblogic 加载的。

从您的 webapp 中删除 JSTL 库，以便 webapp 将只使用 Weblogic 自己的库。
