我想自定义 liferay 停靠栏 view.jsp 页面并想添加一个来自 bean java 文件的文本(项目版本)。但问题是我想初始化java类时出错。我对liferay很陌生,也不知道是否可以在liferay jsp页面中创建外部类对象。这是我的代码::
<%@page import="net.simplyfiIT.bean.UserManagementBean"%>
<%
String version;
UserManagementBean bean=new UserManagementBean();
version=bean.getVersion();
%>
错误信息:
Only a type can be imported. net.simplyfiIT.bean.UserManagementBean resolves to a package
An error occurred at line: 342 in the jsp file: /html/portlet/dockbar/view.jsp
UserManagementBean cannot be resolved to a type
339:
340: <%
341: String version;
342: UserManagementBean bean=new UserManagementBean();
343: version=bean.getVersion();
344:
