WebSphere managed variables are defined at three different scopes: Cell, Node, and Server. I have seen only one example of accessing WebSphere variables from a Servlet, and that was done through JMX, accessing WebSphere management classes. It was not a perfect solution; symbolic references in variables were not automatically substituted, for one thing. There are variables.xml files in the $WAS_HOME/config directory under the cell_name, node_name, and server name directories. It is probably not a good idea (security, complexity) but you may be able to write something to read those files to find the variable value you need.
