Abstract: In the jsp page document obtained absolute path

Well, jsp pages can connect to:
String strurl = "jdbc: odbc: driver = (Microsoft Access Driver (*. mdb)); DBQ = D: \ \ Tomcat 5.0 \ \ webapps \ \ zz3zcwbwebhome \ \ WEB-INF \ \ cwb.mdb";
But this will be the path hard-coded resources in the code, once we have the WEB application move, or change directory, we will have to look for these resources include all jsp to change path. Solution is added directly to each of WEB application to / URL prior to the start. This is not hard-coded name. But the use of getServletContext (). GetRealPath ("/") methods identified in the implementation of this title.
