Wolud u any one please clarify my questions.. How I need to prepare for interview on Jasper reports.
Thak You,
Naresh...

Sub reports provide more layout options (like report headers, groups, more than one detail line, etc, etc), than an embedded table. Subreports do seem to be slower than embedded tables.
I created a report with 6 embedded tables, and then had to change them all to sub reports, when I didn't like the lack of error handling in the tables. I wanted a message that read "No detail records found" (when that occurred) and the table could not handle it, but the sub report did.
