Problem in opening UI API

Hai expertise,

I am trying to open UI API, after installing client copy. I have executed <b>SAPbouiCOM.exe</b> file in the path mentioned below <b>"C:\Program Files\SAP Manage\SAP Business One\"</b>.

It is showing a dialouge box with the following feilds Form ID, Item Num, Row, Col and MenuUID and OK buttionin UI API. I am unable to type anything in that feilds??

Is it the licensing issue.. can we use UI API in trail version of 30 days period???

Can we write code in java to access database objects of SBO using DI API???

Where to use JCo to connect to mySAP solution??? If we are using JCo to connect to other server, will we need to register the file as add-on???

Regards,
