Approach 1 : (Using sc.getInitParameter(-) method)
String s1=sc.getInitParameter("dbpwd");//gives Context Param values
- Here we must know the context param name to get its value.
Approach 2: (Using sc.getInitParameterNames() method)
java.util.Enumeration e=sc.getInitParameterNames();
while(e.hasMoreElements()){
//get each context parameter names
String name=(String)e.nextElement();
//get value of each context param
String val=sc.getInitParameter(name);
pw.println("param name is "+name+", value "+val);
}
Here we get all the context param names and values.
