Ok - I think I figured this out, or at least worked around it. I had the table inside a Frame element. Maybe I didn't have the frame configured properly. Once I removed the table from the frame and republished the report, it worked without error.

After more investigation... Could this be an issue with UUID settings in the jrxml file? How/when are these UUIDs generated? What are they used for within the context of JasperServer?

I'm trying to get my first report working. I *think* I have the report setup correctly - simple table being fed by a remote Postgres database. When I preview the report in Eclipse, the results appear with no problem. I then upload the report to my Tomcat container and receive the following error, pasted below. Worth noting, I'm running JasperStudio 5.5.0, JasperServer 5.5.0, Tomcat 6.0.29, and Postgres 8.4.

I looked in the TableUtil code and tried to trace backwards... I don't have any group data in my table - if I need to provide more info about my table configuration, I can do that as well.
