error with HelloWorld report :(

[tuansandman]

Hi there

I've just create a very simple report (by iReport) with only one static text. When I export to RTF file, the only thing I receive is just a blank file. Does anyone know why. Please help me, it's very urgent

Thank you :)

here is my ReportUtils.java

here is my design file (create by iReport) - http://www.box.net/shared/7r87dkbccg

                                                                                    	    	        	                                	                                                        [/code]

Since the text you want to see is placed on the detail band, you'll need to pass some data when filling the report. Try something like
