Edit: Can not filtering in query since it result in less no of rows. I like to show row even if column value is 0.

Answer 1

You can't remove the entire column in jrxml after the report have been filled, hence what you need means that the report has to be filled first (need to loop all records to see if all is 0).
Your solutions are:
Finding the correct query sql with correct filter (where) that allow you to keep the records but not include the value that is generating the column.
Using pre query's (in example java) to understand how the final query should be pass this query to jasper report via parameter.
Use dynamic-reports or dynamic-jasper, generating the report dynamically first looping datasource to find which columns need to be included.
Post elaborate the Jasper Print before export, deleting and moving objects.
