jsp reads the parameters of the connection database from web.xml

jsp or servlet page code:

String driver = application. getIni tParameter ("driver") ; 
String url = application.getInitParameter("url"); 
String user = application.getInitParameter("user"); 
String pass = application.getInitParameter("pass");

web.xml need to read:

<context-param> 
<param-name>driver</param-name> 
<param-value>com.mysql.jdbc.Driver</param-value> 
</context-param> 
<context-param> 
<param-name>url</param-name> 
<param-value>jdbc:mysql://localhost:3306/j2ee</param-value> 
</context-param> 
<context-param> 
<param-name>user</param-name> 
<param-value>root</param-value> 
</context-param> 
<context-param> 
<param-name>pass</param-name> 
<param-value>32l47</param-value> 
</context-param>
