小编use*_*966的帖子

我收到以下错误:

装配WAR时出错:需要webxml属性(如果在更新模式下执行,则为预先存在的WEB-INF/web.xml)

我到web.xml了正确的地方projectname\src\main\webapp\WEB-INF\web.xml

可能是什么导致了这个？

我想将时间戳2011-03-10T11:54:30.207Z转换为10/03/2011 11:54:30.207.我怎样才能做到这一点？我想将ISO8601格式转换为UTC,然后UTC应该是位置感知的.请帮忙

String str_date="2011-03-10T11:54:30.207Z";
DateFormat formatter ;
Date date ;
formatter = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss.SSS");
date = (Date)formatter.parse(str_date);
System.out.println("output: " +date );

例外:java.text.ParseException:Unparseable date:"2011-03-10T11:54:30.207Z"

PrimeFaces中的数据表中的排序不起作用.请建议.

请参阅下面的.xhtml文件

<h:form>

  <p:dataTable style="width: 60%" id="dt1" value="#{bean.list}" var="entry" first="0" paginator="true" rows="10" paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}" rowsPerPageTemplate="5,10,15" emptyMessage="No cars found with given criteria" >

    <f:facet name="header">
      <h2>Cars View</h2>
    </f:facet>

    <p:column sortBy="#{entry.carno}" filterBy="#{entry.carno}">
      <f:facet name="header">
        <h:outputText value="Car Number" />
      </f:facet>
      <h:outputText value="#{entry.carno}"></h:outputText>
    </p:column>

    <p:column sortBy="#{entry.carsettings['car-model']}" filterBy="#{entry.carsettings['car-model']}">

        <h:outputText value="Car Color"/>
      </f:facet>
      <h:outputText value="#{entry.carsettings.color}"></h:outputText> …

我使用Primefaces 2.2.1和JSF 2.0有数据表的问题.

我在数据表中使用了过滤和分页.当我尝试过滤时,显示所选数据,当我删除过滤器时,显示整个数据.但在此之后,当我尝试使用分页然后suddendly所有行变为空白(空)请参见下面的截图

有什么建议.请帮忙.
