Correction report

In explanation text first line ends like this:

.... In EL, a map's key-value pair can be accessed using either ${map.DBURL} or ${map.["DBURL"]).

Underlined

Code: Select all

${map.["DBURL"]}

is not valid EL.

And I'm ignoring the ) at the end which is obviously a typo.

[admin]

You are right. It should be ${map["DBURL"]}.

As per EL Specification section 1.6:

The EL follows ECMAScript in unifying the treatment of the . and [] operators.
expr-a.identifier-b is equivalent to expr-a["identifier-b"]; that is, the
identifier identifier-b is used to construct a literal whose value is the identifier,
and then the [] operator is used with that value.

This should be fixed asap.

thank you for your feedback!
