How to integrate non-sap application with sap netweaver trial abap

Hi, I currently have with me SAP Netweaver ABAP trial and Mini SAP BASIS 4.6 D. What i want to do is to see how can i integrate my non-SAP application with SAP.

I am confused as to if using SAP Netweaver ABAP trial, will i be able to establish that. Can anyone guide me in this regard.I want to connect using JCO basically, want to write a java client that will be talking with the SAP application. Provide me a starting point.

Will i require a Deployed SAP application as well to do this, or will Netweaver ABAP Trial do the job, will i also have to expose the business objects using BAPI.

Please help.

Please point out the right forum to post the question if this is not the right one.

Thanks
