How to Post JSON Data using AJAX Call in SAP UI5

Hi Experts,

Please help me.

I am using the NWDS 7.30 for SAP UI5 development.I am stuck in the below mentioned case.Please help me on this.

My requirement is I need to post or get JSON Data from my database. So that i have used JAVA-JSON jar to implement the case.But when I am run the project it will throw an error that "500 internal server error" for the JQuery ajax json post/get to the servlet. When i check the error log it says that org/json class not found exception.But I have already maintained in java builder path.

In the eclipse i have there have a option "Deployment Assembly"(If we use json jar to fetch some data from server we have to maintain in that area)

But in NWDS there are no such option like that.I need to develop application  in NWDS 7.30 only.

Please help me on that.

Thanks & Regards,
