提交后 JSP 页面从浏览器中消失

这是我第一次使用 struts (1.2)

在我的 jsp 页面中，我有一个表单，用户需要提供 IP 地址和文件名，一旦他提交页面，该数据就会传递到一个连接到的 Web 服务设备并收集给定文件名中的数据。

现在的问题是，当我在一段时间后使用按钮提交页面时（在 IExplorer 上大约 1-2 分钟，在 Firefox 上大约 4-5 分钟），我的应用程序页面消失了；我在应用程序日志或 weblogic 日志中没有看到任何错误。

这是一个同步请求，用户必须在 UI/网页上等待最终结果显示，大约需要 30-40 分钟下面是 struts-config.xml 中的片段

    <action 
        path="/Collect"
        type="com.aqura.project.struts.fileMgt.CollectResultAction"
        validate="false">
          <forward name="Collect" 
                   path="/jsp/collect.jsp"/>
    </action> 

    <action
        path="/CollectDisplay"
        type="com.aqura.project.struts.fileMgt.CollectResultAction"
        name="collectForm"
        scope="request"
        validate="true"
        input="/jsp/collect.jsp">
          <exception
              key="exception.prodconn.error"
              type="com.aqura.project.service.prodConnect.ProductConnectException"
              path="/jsp/ctError.jsp" />
          <forward name="FileTransferDisplay"
                   path="/jsp/fileTransferDisplay.jsp" 
                   redirect="true"/>
          <forward name="FileResolve" 
                   path="/FileResolve.do" 
                   redirect="true"/>
    </action>

。collect.jsp 是此操作的 jsp 文件，用户必须在此页面上等待，直到我们成功获取文件，一旦收到文件，我们将检查它是否存在并且需要将其删除。重命名，否则它将存储在用户 a/c 中。

逻辑写在 CollectResultAction.java 上，我们在其中映射了操作。

在过去的一周里，我一直在为这个问题苦苦挣扎，却一无所获。

我尝试使用 <%c:out /> 在 JSP 上放置一些日志但这也不起作用。我不知道如何调试这个问题。任何帮助将不胜感激。

另一个更新：我在.jsp文件中添加了html刷新标签，现在FireFox页面上的此更改一直保留到显示最终结果，但在IE上我仍然看到这个问题，我已经尝试过IE6和IE8 。

原文

This is the first time I am working with struts (1.2)

In my jsp page I have a form, user needs to provide IP address and filename, once he submit the page, this data is passed on to a web service which does connection to the device and collects data in the given file name.

Now the problem is, when I submit the page using the button after a while(around 1-2 minutes on IExplorer and 4-5 minutes on firefox) my application page disappear's; I don't see any error's in my application logs or weblogic logs.

This is a synchronous request and user had to wait on the UI/webpage for the final result display which takes around 30-40 minutes
below is the snippet from the struts-config.xml

    <action 
        path="/Collect"
        type="com.aqura.project.struts.fileMgt.CollectResultAction"
        validate="false">
          <forward name="Collect" 
                   path="/jsp/collect.jsp"/>
    </action> 

    <action
        path="/CollectDisplay"
        type="com.aqura.project.struts.fileMgt.CollectResultAction"
        name="collectForm"
        scope="request"
        validate="true"
        input="/jsp/collect.jsp">
          <exception
              key="exception.prodconn.error"
              type="com.aqura.project.service.prodConnect.ProductConnectException"
              path="/jsp/ctError.jsp" />
          <forward name="FileTransferDisplay"
                   path="/jsp/fileTransferDisplay.jsp" 
                   redirect="true"/>
          <forward name="FileResolve" 
                   path="/FileResolve.do" 
                   redirect="true"/>
    </action>

collect.jsp is the jsp file for this operation and user has to wait on this page until we get a file successfully, once file is recieved we will check if it exist and needs to be renamed otherwise it will stored in user a/c.

logic is written on CollectResultAction.java, where we have action mapped.

I have been struggling with this issue for the past one week, and not able to make anything out.

I tried to put some logs on the JSP using <%c:out />
but that also didn't work. I am not sure how to debug this issue. Any help would be appreciated.

Another Update:
I have added html refresh tag in the .jsp file, with this change now on FireFox page stays till final result is displayed, but on IE I am still seeing this issue, I have tried with IE6 and IE8.
