我有一個彈簧控制器,我在其中返回一個名爲「model」的Map;模型包含一些值,但重要的還包含一個ArrayList
。現在我將這個Map返回給我的JSP,而在我的JSP中使用JSTL來獲取ArrayList
它會拋出錯誤。使用JSTL訪問從Spring Controller到JSP的映射時出錯
<c:forEach items="${model.result}" var="data" varStatus="status"> <!-- result is my ArrayList -->
<c:out value="${data.url}" /> <!-- here url is data inside my result arraylist -->
</c:forEach>
產生的錯誤是:

java.lang.NoSuchMethodError: javax.servlet.jsp.PageContext.getELContext()Ljavax/el/ELContext;

它的工作原理Tomcat服務器上的罰款,但是當我Weblogic上部署它(9.2)服務器它給人的錯誤。我的類路徑條目:

更新:我已刪除了JSTL-1.2.jar現在我得到一個編譯錯誤:
searchsuccess.jsp:1:5: No tag library could be found with this URI. Possible causes could be that the URI is incorrect, or that there were errors during pa
rsing of the .tld file.
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

另外,我看到的地方....不使用JSP-api.jar文件,但它不是的情況下我,因爲我沒有任何jsp-api.jar在我的web應用程序..:P – GOK
