Hi Samisa, When you take the parameters from the request they are not type bound. they will be always String, and if you are sure that some parameter is an Integer you can cast it to a Integer and do math operations on it.
It goes same for Java HTTPServletRequest [1] [1] http://docs.oracle.com/javaee/6/api/javax/servlet/ServletRequest.html#getParameter(java.lang.String) Regards, /Nuwan On Tue, Mar 6, 2012 at 8:07 AM, Ruchira Wageesha <ruch...@wso2.com> wrote: > I don't think it is possible to differentiate request parameters as > strings, integers, floats etc. i.e. when we pass something as a request > param from the client side, we don't consider their types. > > If I have understand your question properly, what is would be > the rationale behind identifying params in [1] as numbers and [2] as > strings? > > Thanks & Regards, > Ruchira > > [1] http://foo.com/calc?param1=1¶m2=2 > [2] http://foo.com/search?param1=hello¶m2=world > > On Mon, Mar 5, 2012 at 8:29 PM, Samisa Abeysinghe <sam...@wso2.com> wrote: > >> Reason I am saying is that I wrote a cal to demo session and >> the param could not be added out of the box.
