You need to register a 

javax.servlet.ServletContextListener

in your web.xml like this: 

<listener>
    <listener-class>com.my.Servlet</listener-class>
</listener>

From that, you can get the ServletContext on which you can call getContextPath().

You can get the absolute path to to your webApp/WEB-INF/classes directory as below:

URL resource = getClass().getResource("/");
String path = resource.getPath();

This will return you an absolute path like this:

/C:/SERVERS/x/y/x/yourApp/WEB-INF/classes

And from this you can get the path to the yourApp directory:

path = path.replace("WEB-INF/classes/", "");

which you can use to specify paths like /Rod1/thermalMap.exe, by appending to this path.

Have you try this?

 String path = new File(".").getCanonicalPath();
