在我的jsp页面中，我有以下代码片段。在我的流程中，这个页面以递归的方式进行。我在流程中间执行jsp时遇到重复的bean id错误。你能帮助我如何检查bean id是否已经存在以下代码？

正如您所说This page is coming recursive way during my flow.
尝试将scope="page"更改为scope="request"
或尝试将beanId重命名为"orbinfra1"
<jsp:useBean id="orbinfra1" scope="session" class="com.ubsw.risk.Creation.web.OrbinfraBean" >
<jsp:setProperty name="orbinfra1" property="propertiesFile" value="<%=path%>"/>
</jsp:useBean>
