Dear sirs,

I am quite new to Jasper Report , i am making a desktop application , and i use oracle database.

all what i need from jasper to preview the search results or the ResultSet -all results already in a table- in Jasperviewer in order to print it,

please notice that i cannot even run the attached samples which came with the package, i always get that exception:
