我正在学习 Struts2，并在托管我的应用程序时遇到以下问题。index.jsp页面，具有/struts-tags 示例 <s:form>, <s:url>等，在托管应用程序时抛出异常。

项目中使用的 jar :

common-lang3.jar
commons-fileupload-1.3.jar
commons-io-2.0.1.jar
commons-logging-1.1.3.jar
commons-logging-api-1.1.jar
freemarker-2.3.19.jar
javassist-3.11.0.GA.jar
ognl-3.0.6.jar
struts2-core-2.3.15.3.jar
xwork-core-2.3.15.3.jar

异常堆栈跟踪:

    **HTTP Status 500 - An exception occurred processing JSP page /index.jsp at line 12**
    **type** Exception report
    **message** An exception occurred processing JSP page /index.jsp at line 12

    **description** The server encountered an internal error that prevented it from fulfilling this request.

    **exception**

    14:       <s:textfield name="age" label="Age" size="20" />
    15:       <s:submit name="submit" label="Submit" align="center" />

请建议我如何解决此问题。

最佳答案

您的项目中似乎部署了不完整的库 jar。尝试从 Maven 存储库下载所需的 jar 或在 struts 发行版 lib 文件夹中查找它们。 

commons-lang3-3.1.jar

缺失。
