1.情景展示
在eclipse下,启动成功后,项目网页能正常打开,但是在服务器的tomcat上运行时,报错:
2.问题分析
主要原因:项目需要jstl标签库,在jsp页面引入jstl时报错
在eclipse中为什么不会报错?
调用jstl标签库需要引入jstl的jar包,在eclipse下web项目需绑定tomcat,
tomcat的lib目录下有jstl.jar包,eclipse会自动将lib下的jar包绑定到项目当中
所以,项目可以正常访问。
3.解决方案
添加jar包并构建到项目当中。
第一步:jar包
方式一:
jstl1.1版本 由2个必要包构成:standard-1.1.jar和jstl1.1.jar;
方式二:推荐使用
jstl1.2版本 只有一个必要包jstl1.2.jar。
tomcat6.0既支持jstl1.2版本,也支持jstl1.1版本
然后,将所需jar包拷贝到WEB-INF/lib目录下
第二步:构建项目
选中jar包-->右键Build Path-->Add to Build Path
