Struts form which submit many times...

[Serge Montet]

Hello, I am a beginner in Java technologies...
I am working on a Struts project with J2EE.
It's a web site which is creating with Xen API some virtual machines.
There is a create machine form which asks for example the OS wanted, memory size, etc. Then it is executed by JMS in a queue.

Here are Struts actions for creating a machine :

<action
      path="/prepareCreateVirtualServer"
      type="com.virt.presentation.action.create.PrepareCreateVirtualServerAction">
      <forward name="success" path="/createVirtualServer.jsp"/>
    </action>
 
<action
      path="/createVirtualServer"
      type="com.virt.presentation.action.create.CreateVirtualServerAction"
      name="virtualServerForm"
      scope="request"
      validate="true"
      input="/preparecreateVirtualServer.do">
      <forward name="success" path="/viewVirtualServers.do" redirect="true"/>
    </action>

Now I am being asked to make a validation workflow.
That is to say when someone asks for a virtual machine creation, the admin receives an email and click on it if all is ok.
Example for machine id=10

<a href="http://localhost:8080/validVirtualServer.do?id=10" target="_blank" rel="nofollow">http://localhost:8080/validVirtualServer.do?id=10</a>

Then the web page viewvirtualserver.jsp is launched, it displays all manipulation possible (start-up, shut-down etc).

For some technical reasons, this page is refreshing every 10s.
And now the problem : the creation form is submitted every 10s with the refreshing of that jsp page...!!!
I cannot see why :

The action of validation :

<action
      path="/validVirtualServer"
      scope="request"
      type="com.virt.presentation.action.control.ValidVirtualServerAction">
       <forward name="success" path="/viewVirtualServers.do"/>
    </action>

How can I avoid this problem in Struts or jsp code ??

Thanks a lot.
