applicationScope in EL

[Srinu Nanduri]

The following is a mock exam question from Javabeat.

28) The Deployment Descriptor for a Web Application looks like this,
<context-param>
<param-name>maxConnections</param-name>
<param-value>37</param-value>
</context-param>
Which of the following EL expressions rightly access the value of the parameter
'maxConnections'?
a. ${applicationScope.maxConnections}
b. ${applicationScope["maxConnections"]}
c. ${applicationScope['maxConnections']}
d. All the above

I dont think any of the above four is a right answer. All that we can access through the applicationScope are just the attributes bound to the application scope. Is my understanding right?

another one in the same line..

32) Which of the following are equivalent forms for the Scriptlet?
String gradeValues[] = request.getParameterValues("grades");
String value = gradeValues[0];
a. ${requestValues.grades['0']}
b. ${requestValues.grades.0}
c. ${requestValues.grades['0']}
d. ${requestValues.grades."0"}
e. ${requestValues.grades["0"]}
f. ${requestValues.grades.'0'}
g. All the above

I wonder if there is an implicit object by name "requestValues"?

28) All wrong. They should use initParam instead of applicationScope.
32) You're right. They probably meant paramValues.

Thanks Christophe!
