JBuilder2005实战JSP之特殊页面(5)_MySQL
JBuilder
欢迎页面welcome.jsp
当用户录入正确的密码后，switch.jsp控制JSP页面导向welcome.jsp欢迎页面，在这节里，我们来开发这个welcome.jsp页面。因为welcome.jsp需要使用到一个第三方的标签库，所以在开发welcome.jsp之前需要在JBuilder中作一些配置引入这个标签库。
将第三方标签库配置到JBuilder中
Apache开源组织提供了许多有用标签库，欢迎页面welcome.jsp需要使用一个来源于Apache的datetime标签库，可以用这个标签库在JSP中提供各种时间的显示，下载的地址是：http://apache.justdn.org/jakarta/taglibs/datetime/binaries/jakarta-taglibs-datetime-1.0.1.zip。
标签库一般包括两个文件，其一是类包JAR文件，其二是以.tld为扩展名的标签符描述文件。从下载的压缩文档中解压后，我们将taglibs-datetime.jar和taglibs-datetime.tld文件放到＜工程目录＞/datetimeTag目录下。
要在工程中使用第三方的标签库，必须事先在JBuilder中配置这个标签库，并在工程中引用它。配置标签库和配置类库相似，也是通过Configure Libraries对话框来完成。JBuilder类库及标签库都列在Configure Libraries对话框中左边的树中，类库显示为
图标，而标签库显示为
图标。下面我们来将datetime标签库配置到JBuilder中。
1．Tools-＞Configure-＞Libraries-＞Configure Libraries对话框。
点击Configure Libraries对话框的左下角的Add...按钮，弹出New Library Wizard对话框，如下图所示：
