Subreports and datasets not showing

[vandana.gck]

Hello people, I am having an issue with including subreports, lists and table datasets in the main report using jasper reports since i want to include two separate sql queries in my report. I am using the same connection to my database for both the main report and the other dataset. The problem is that when i preview the report using the iReport designer it shows everything i want to see, but when i use the php-jasper library in my php script to call the .jrxml file and output a pdf it does not show the sub-report, lists or table datasets i have put. If anyone could tell me how the php-jasper library works or a solution to my problem, i would greatly appreciate that.
