Jochen,
thank you. It appears that the setting of the variables in Form at the client side is OK.
At the server, I DO GET the string surrounded by "[ ]".
I am enclosing another image; this is at the server side where the parameter "fileList" (Java parameter inFileList) is received.
My service fails because of the enclosing [] when I loop through the list.
I am using JDK6. But I think the REST code at the server side is not handling the List<T> @FormParam as a List but as a T (String).

Hi Gisella,
are you sure you're not just misinterpreting the output of your debugger?
As far as I can see from your explanation and the screenshot, it should
be all perfectly fine.
Your debugger displays the items of Java collections in square brackets
("[" and "]").
So
| fromMillis -> [1234567890]
means that your HashMap contains an entry with the key "fromMillis" and
the value "1234567890".
| fileList -> [[C:\\N4\\sandbox...]]
accordingly means that your HashMap contains an entry with the key
"fileList" and that the value is a List which contains the value
"C:\\N4\\sandbox...". Thus the two pairs of square brackets.
If your List contained another Collection, you could also get something like
| fileList -> [[[foo], [bar]], [[foo2], [bar2]]]
If you anticipate to only get a flat string value (e.g. comma-separated)
for inFileList, you should not declare it as List<String> but as String.
HTH,
Jochen
