This can be done, but it requires manual editing of a JSP file. You will need to do the following:
1) Configure a process that would display the url:
DISPLAY URL boContact.WebDirectoryURL
2) Define a menu item that would run this process
This will only display the url in the same window. To get Aware IM to display it in a new window you will need to edit the file that starts with "BAS_MenuV...".jsp and located in the AwareIM/Tomcat/webapps/AwareIM directory.
You will need to find the line starting with
<menu:menuitem ...
corresponding to the item that starts the process and edit this line to add the following:
<menu:menuitem target="_blank" ...
An alternative solution is to use a completely custom menu with a hyperlink that starts the process. At the HTML level the hyperlink would also have a target="_blank" attribute.
You can look up sample applications that contain examples of such menus.
