You should edit the question and add more info in it. – Luiggi Mendoza Nov 20 '12 at 01:57
Also, the web methods should contain the ways to access the data, not the Web Service constructor. If you want/need to load the `sales` attribute only once, make it `final static` and load it in a `static` code block. – Luiggi Mendoza Nov 20 '12 at 02:00
how can grant access for my data to the webmethod? – Mahmood Majadly Nov 20 '12 at 14:22
Move the code from the constructor (that will never be called like that) to your `getOpenSales` method. If you only need to load the data once, use a [Static Initialization Block](http://stackoverflow.com/q/2420389/1065197). – Luiggi Mendoza Nov 20 '12 at 14:28
