Yes, but you will need to provide custom HTML or jsp page. A very crude example of such a page is shown below. You can take this file or modify it or provide your own HTML file (if you do this then the URL that you will need to specify for the Logon button or link is http://localhost:8080/AwareIM/logonOp.jsp).
You will need to specify the name of the page as the parameter for the Logout menu item (assuming that your page is in AwareIM/Tomcat/shared/webapps/AwareIM directory):
<html>
<head>
</head>
<body >
<table border="0" width="100%" >
<tr>
<td align="center">
Logout successful. Good-bye.
</td>
</tr>
<tr>
<td align="center" >
<a href="http://localhost:8080/AwareIM/logonOp.jsp" >
Logon
</a>
</td>
</tr>
</table>
</body>
</head>
</html>
