[JEXL] Creating map in JEXL 1.1 fails
Hi,
I am trying to use JEXL 1.1 embedded within a J2SE application.
I am trying to create a map in JEXL as described here
http://commons.apache.org/jexl/reference/syntax.html#Literals
My expression looks something like this:
String myExpression="[\"key1\"=>\"value1\",\"key2\"=>\"value2\"]";
However JEXL throws the exception below when I try to create the
expression object using:
ExpressionFactory.createExpression(myExpression);
How does my expression need to look like if evaluating the expression
should return a Map object.
Thanks in advance,
Seb
The exception:
--------------
org.apache.commons.jexl.parser.ParseException: Encountered "[" at line
1, column 1.
Was expecting one of:
<INTEGER_LITERAL> ...
<FLOAT_LITERAL> ...
"empty" ...
"(" ...
"size" ...
"-" ...
"~" ...
"!" ...
"not" ...
"null" ...
"true" ...

Does an assignment help,
e.g. "x = ...."

Yes, it is, as I mentioned below.
I will try to amend that (but it won't be for a couple of weeks
atleast, since I'm traveling).

Hi Rahul,
thanks for your answer. I downloaded the latest nightly build and it
works now. It is a bit unfortune that the website shows the API of a not
yet released version and the download section
(http://commons.apache.org/jexl/downloads.html) only lists the stable
releases with a smaller set of functionality.
Regards,
Seb

That bit of functionality was added after the 1.1 release (the docs
are for 1.1.1-SNAPSHOT -- unfortunately, I'm not sure if we have
retained the 1.1 docs anywhere on the site) i.e. you'll have to build
the trunk to try out the above.
