How to access static resources in ear without specifing context-root

Question

Hello, i have a problem with my ear.
The war's structure is like this:
---/jsp
---/css
---/images/ViewRisposte.gif
---/xsl/Request.xsl
---/Common/data.xsl
/error.xsl
/input.xsl
xsl files reference css and images files that are contained in css and images dir.
I can't use the "../" to specify css and images path into xsl and jsp due to security policy setting on the Http server (and I can't change this policy).
In the ear's application.xml is specified the context root of the module web with the name SABEARWeb
<?xml version="1.0" encoding="ISO-8859-1"?>
<application>
<display-name>SABEARWeb module</display-name>
<module>
<web>
          <web-uri>SABEARWeb.war</web-uri>
          <context-root>SABEARWeb</context-root>
     </web>
</module>
</application>
For example with this following code (Request.xsl), how can i replace the "../" notation to access xsl and image resouces without write the context root? How i can insert the images and css references into xsl and jsp files?
<xsl:import href="../Common/data.xsl" />
<img align="center" width="20" src="../images/ViewRisposte.gif" id="viewXslRisp" title="Visualizza Risposta">...</img>
Thanks a lot

>>As I understand I should change View1 by handling command of button “Edit”, and then View 2 should be displayed, then I change data and then View1 should be updated. How to do it?
For information about how to handle a command, please refer to my blog post:
http://blog.magnusmontin.net/2013/06/30/handling-events-in-an-mvvm-wpf-application/
You could bind the Command property of the edit button to an ICommand property of VMMain. When this command is executed you could then send a message using an event aggregator or some kind of messenger. Please refer to my blog post for more information about
how to for example use Prism's event aggregator class to pass events between view model classes:
http://blog.magnusmontin.net/2014/02/28/using-the-event-aggregator-pattern-to-communicate-between-view-models/
Andy has written an example of how to use MvvmLight's Messenger class:
http://social.technet.microsoft.com/wiki/contents/articles/26070.communicating-between-classes.aspx
The concepts are the same but you will have to download and reference either Prism:
https://www.nuget.org/packages/Prism/
...or MvvmLight: https://www.nuget.org/packages/MvvmLight/
You then subcribe to this event or message in the main view model and change the value of the CurrentPageViewModel property whenever you recieve an event. Note that the class must implement the INotifyPropertyChanged interface and raise its PropertyChanged
interface for this to work:
https://msdn.microsoft.com/en-us/library/system.componentmodel.inotifypropertychanged%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396
This is how you are supposed to communicate between different view model classes.
Hope that helps.
