[xwiki-users] Importing .xar in virtual wiki

Hello, I am trying to install a virtual wiki by following the steps given in "Creating a virtual XWiki environment" - everything worked fine except the very last step - for some reason I cannot import the .xar file in the virtual wiki. I select it and it appears in the list under "Select the file you wish to import", but when click on the file name, instead of seeing all the objects with the checkboxes, I get an error message "The page cannot be displayed" and in the address of the opened page: javascript:void() Any idea how to solve this problem? (I had the .xar file successfully imported in the main wiki (the controller). Thanks, Darina
