My report works fine in the eclipse prevew, but when I load it into the web
viewer, I always get:java.lang.NullPointerException: dataSource param cannot
be nullWhat does this mean? I have tired passing in all the report
parameters on the URL, but still get this error.Dont know where to look.The
tutorial sample reports work fine.Thanks,Birt.

I think a data source parameter is actually a data set parameter. I have
set these up correctly, and they worked fine with 2.0.0 viewer and in
preview, but dont seem to work at all with 2.1.0M5.

I ahve something like:

shopid Any params["rp_shopid"]

In my data set binding for the list.

Have you defined some default values for your parameters on the Edit Data
Set window?
