java.lang.IllegalArgumentException: No bean specified at org.apache.commons.beanutils.PropertyUtilsBean.getPropertyDescriptor(PropertyUtilsBean.java:751) at org.apache.commons.beanutils.BeanUtilsBean.setProperty(BeanUtilsBean.java:937) at org.apache.commons.beanutils.BeanUtilsBean.populate(BeanUtilsBean.java:811) at org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:298) at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:493) at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:805) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:203) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1194) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:432) at javax.servlet.http.HttpServlet.service(HttpServlet.java:709) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:667) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:595) 解决办法: 没有知道相对应的formbean.需要在对应的form当中实例化一个出来 在这里我是用的是动态的上传附件在form当中定义了一个private list myFiles; 需要在form空的构造函数当中实例化一个myFiles;请看: public myForm() { myFiles = new List(); *****下面是你自己所需要的了*** } 呵呵。成功了! 声明:ITeye文章版权属于作者,受法律保护。没有作者书面许可不得转载。
