ssh 报 could not inspect JDBC autocommit mode

这几天做SSH时，在刷新页面和多次跳转时经常报一个异常，如下：

javax.servlet.ServletException: could not inspect JDBC autocommit mode
 org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:545)
 org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:486)
 org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:274)
 org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482)
 org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:525)
 javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
 javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

不知道怎么解决，请各位前辈指教！！
