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

时间：2011-11-15 07:13:15

标签： java spring jstl tomcat5.5

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：

我参考了JSTL库，如下所示：

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

我的图书馆有以下的罐子：

asm-3.1.jar
cglib-2.1.jar

org.springframework.web.struts-3.0.6.RELEASE.jar
standard-1.0.4.jar
velocity-1.6.jar

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，对于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/的标记库描述符核心“在jsp中。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文件夹中（我在共享的Tomcat上）。

我根据需要添加/删除了以下jar以解决此问题，但是有一个例外或另一个例外。 

el-api-6.0.20.jar
jstl-1.1.0.jar
jstl-1.1.2.jar
jstl-1.2.jar
jstl-api-1.2.jar
jstl-impl-1.2.jar

有人知道解决方案吗？

感谢。

答案 0 :(得分：9)

从/WEB-INF/lib列表中

jstl-1.2.jar

此JAR包含两者 JSTL 1.2 API和实现，而这又需要最少的Servlet 2.5 / JSP / EL 2.1。 {/ 1}}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。

javax.el

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，它在URI中不包含standard-1.0.4.jar ，这解释了在用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。您需要删除两个上面提到的JAR（JSTL 1.2 API / impl和JSTL 1.0 impl），然后将它替换为JSTL 1.1的两个JAR，您可以下载here。您可以在ZIP文件的/jsp文件夹中找到jstl.jar和standard.jar。
