usebean在eclipse中使用mysql的Java连接包不适用于jsp页面

我在eclipse中制作了一个包，用于连接到wamp服务器的mysql，以执行我对jsp页面的sql查询。同样的代码在netbeans上运行得非常好，但在eclipse上却不行。我认为这是因为我在netbeans上使用了glassfish服务器，在eclipse上使用了tomcat。我的包位于eclipse中java包的src文件夹下

这是我的javabean对象

<jsp:useBean id="c1" scope="page" class="sql.connect" />

假设“connect”是您的类（嗯，名字很奇怪，您确定在sql.connect之后没有遗漏什么吗？），您是否尝试过使用简单导入而不是直接bean导入？我不工作。它在netbeans中工作得非常好，但在eclipse中不行。
