displaytag 1.2 安装问题的解决

2010-09-18 17:06

 

1、首先在网页上下载 http://displaytag.sourceforge.net/

2、参照 http://displaytag.sourceforge.net/1.2/install.html 中的安装向导，把displaytag加入我们的工程中：

下载包中包含以下内容：


           文件名                                           描述
           displaytag-1.2.jar                         main taglib jar
           displaytag-export-poi-1.2.jar              optional excel export module
           displaytag-portlet-1.2.jar                 adapt displaytag for use in JSR-168 portals
           displaytag-examples-1.2.war                web application with examples
将displaytag-examples-1.2.war 放入tomcat目录下\webapps下，重启tomcat服务器会出现以下错误信息：

严重: Error processing TLD files for context path /displaytag-examples-1.2
javax.servlet.ServletException: Exception processing TLD at resource path /WEB-I

解决方法： 把displaytag-1.2.jar中的displaytag.tld文件解压到D:\apache-tomcat-6.0.20\webapps\displaytag-examples-1.2\WEB-INF目录中并重命名为 displaytag-11.tld后能启动服务

3、安装后的试运行

在浏览器地址栏输入： http://localhost:8080/displaytag/    则可以看到displaytag的运行示例页面，表示安装成功。
