Hi, I try to do an iteration on a vector. When this vector contains only Strings, the iteration works well. For that, I use the following piece of code:
><logic:iterate id="elt" name="listform" scope="session" property="vect"> > <bean:write name="elt" /><BR> ></logic:iterate> But, when I try with a vector containing custom objects, it doesn't work :( For example, I have a Vecor of Element. Element is a bean which contains 2 attributes (2 String named: id and name) To iterate on that vector, I use the following piece of code: ><logic:iterate id="elt" name="listform" scope="session" property="vect" >type="be.stluc.info.struts.Element"> > <bean:write name="elt" property="name"/><BR> ></logic:iterate> That doesn't work, and the following exception is thrown: >Apache Tomcat/4.0.1 - HTTP Status 500 - Internal Server Errortype >Exception reportmessage Internal Server Errordescription The server >encountered an internal error (Internal Server Error) that prevented it >from fulfilling this request.exception java.lang.ClassCastException: >java.lang.String > at org.apache.jsp.ListNames$jsp._jspService(ListNames$jsp.java:178) > at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) > at > org.apache.jasper.servlet.JspServlet$JspServletWrapper.service(JspServlet.java:202) > at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:382) > at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:474) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) > at > org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:679) > at > >org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:431) > at > >org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:355) > at > org.apache.struts.action.RequestProcessor.doForward(RequestProcessor.java:970) > at > >org.apache.struts.action.RequestProcessor.processActionForward(RequestProcessor.java:404) > at > org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:269) > at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1099) > at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:468) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:760) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) > at > >org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247) > at > >org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:193) > at > org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:243) > at > org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) > at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) > at > org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:201) > at > org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) > at > org.apache.catalina.valves.CertificatesValve.invoke(CertificatesValve.java:246) > at > org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) > at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) > at > org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2344) > at > org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:164) > at > org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) > at > org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve.java:170) > at > org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) > at > org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:170) > at > org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) > at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) > at > org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:163) > at > org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) > at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) > at > org.apache.catalina.connector.http.HttpProcessor.process(HttpProcessor.java:1011) > at > org.apache.catalina.connector.http.HttpProcessor.run(HttpProcessor.java:1106) > at java.lang.Thread.run(Thread.java:536) Could somebody please show me the right way to acomplish the iteration ?
