我的 Web 应用程序中出现以下错误。我已经在 JSF 上工作了一段时间了，但是我找不到这个错误的解决方案。
Nov 27, 2013 11:00:52 PM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: servlet.service() for servlet Faces Servlet threw exception
org.apache.jasper.el.JspMethodNotFoundException: /CustomerPFM.jsp(70,2) '#customerPfmBean.MakeConnections}' Method not found: bean.CustomerPfmBean@1900abac.MakeConnections()
这是我的 JSP
