Hi,  
First, lets say that I am not using ireports from jasper, I am using  
BIRT on glassfish and have it integrated through html links.  
I would first check out the database statement that you are issuing,  
as sometimes if data on joins it may not bring back anything.  
If that sql statement gives you a result set, I would try running the  
report on a local machine where the repository is, to see if you get  
results.  
If you are successful with running the report on the db machine, run  
it on another machine outside of your program.  
If successful there run it on that machine, check to see if your  
program can connect to the database.

I know that jasper, like birt , is a java program and it needs to be  
run on a java server. Integration is usually done through links, but  
can be fully integrated if you use jRuby. If you do it through html  
links, take a look at the servers log files, they usually are a gold  
mine of information.

i think you should check your log info.  
if not,check the component size,assure it is proper in the band.
