Re: [configuration] Re: Space or single quote as a value in properties files
Thank you Oliver, However with some simple tests that I've ran, I saw that even XMLConfiguration does not support this feature. It would be nice to see that as an option in the Apache configuration module, at least for me, its been many times that I need such values in a configuration file. thank you again, -- Asterios On Thu, Feb 4, 2010 at 10:18 PM, Oliver Heger oliver.he...@oliver-heger.dewrote: Am 04.02.2010 17:42, schrieb Asterios Katsifodimos: Hi all, I would like to know if there is a way to set the value of a variable (key) to be the space character in a PropertiesConfiguration file. for example variable = could I use the double quotes to do that?

Test for firsst Derivative in PolynomialFunction ERROR
I have written the attached test using our data for generating a curve function However the first derivative test fails see: testfirstDerivativeComparisonFullPower Either my test is in error or there is a bug in PolynomialFunction class.

[math] Re: Test for firsst Derivative in PolynomialFunction ERROR
Hi Roger, First of all, could you add the [math] marker in the subject line (like I have done) when posting to this list about the commons-math component ? This list is shared among all Apache commons components and such markers help people filtering messages. roger.b...@creoss.com a écrit : I have written the attached test using our data for generating a curve function However the first derivative test fails see: testfirstDerivativeComparisonFullPower Either my test is in error or there is a bug in PolynomialFunction class. The list removes attachements. If you think you have found a bug, please open a Jira issue at http://issues.apache.org/jira/browse/MATH. Once the issue is opened, you will be able to attach your example code to it.

This can be achieved by adding the xml:space attribute on an XML element. Have a look at the following example extracted from our unit tests: space xml:space=preserve blanc /blanc /space The value of the space.blanc property will be a space character. (Note that the xml:space attribute is a standard XML attribute, not a specific extension for XMLConfiguration).
