javax.servlet.jsp.JspException:Tomcat 5.5中的javax/el/ValueExpression

Question

javax.servlet.jsp.JspException:Tomcat 5.5中的javax/el/ValueExpression

我的Spring应用程序(webapp ver 2.5)在Tomcat 6.0上运行良好.但是,在我将其转换为webapp ver 2.4以在Tomcat 5.5上运行之后,我遇到了以下异常:

正如我从其他帖子中了解到的,它与jstl有关,而且jstl-1.2.jar是不兼容的.但是,使用jstl-1.1.2,jstl-1.1.1和jstl-1.1.0我收到错误找不到"http://java.sun.com/jsp/jstl/core"中的标记库描述符 JSP.我认为这可以通过添加c.tld和其他tld文件并在web.xml中引用这些文件来解决.为此我想我需要将它们添加到我无法访问的tomcat文件夹(我在共享的Tomcat上).

我根据需要添加/删除了下面的罐来解决这个问题,但是有一个例外或者另一个例外.

el-api-6.0.20.jar

jstl-1.1.2.jar

从您的/WEB-INF/lib列表中:

jstl-1.2.jar
Run Code Online (Sandbox Code Playgroud)

此JAR包含两者的JSTL 1.2 API和实现,这又需要一个最小的Servlet 2.5/JSP/EL 2.1.该javax.el包是在JSP/EL 2.1中引入的,但Tomcat 5.5不支持它,因此解释了您在问题中发布的异常.

standard-1.0.4.jar
Run Code Online (Sandbox Code Playgroud)

此JAR包含JSTL 1.0实现和taglib.这实际上需要一个JSTL 1.0 API JAR文件.JSTL 1.0的taglib URI也不同,它不包含/jsp在URI中,因此解释了在用JSTL 1.1 API替换JSTL 1.2 API/impl时得到的taglib URI错误(不,JSTL 1.1 API库不包含impl!).

Tomcat 5.5是一个Servlet 2.4容器,仅与JSTL 1.1一起使用.您需要删除上述两个 JAR(JSTL 1.2 API/impl和JSTL 1.0 impl),然后将其替换为JSTL 1.1的两个JAR,您可以在此处下载.它是jstl.jar和standard.jar你可以中找到/libZIP文件文件夹中.
