我刚刚开始使用jsp，但到目前为止还有一些问题。我正在尝试使用bean但收到错误并且不确定如何修复它。
我在/ WEB-INFO / lib文件夹中添加了以下Jar文件： servlet.jar和javax.servlet.jsp-api.jar
Bean Path = /T_04_JSTL_01_Bean/src/MyPackage/Bean1.java
Bean Location = C：\ Users \ Dave \ My_WorkSpace \ Eclipse_Workspaces \ workspace-jsp \ T_04_JSTL_01_Bean \ src \ MyPackage \ Bean1.java
JSP文件代码：
<jsp:useBean id="userBean" class="MyPackage.Bean1" />
错误：
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: [52] in the generated java file: [C:\Users\dave\My_WorkSpace\Eclipse_Workspaces\workspace-jsp\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\work\Catalina\localhost\T_04_JSTL_01_Bean\org\apache\jsp\ex01_005f2_jsp.java]
