Well I check that, but that only allows to show/hide columns that are already part of report. What if I have a list of 100 possible fields that can exist in the universe but based on run time parameter selection only 20 need to appear as columns. Additionally some of the users would want the report made available as PDF and dont want any interactive viewer. Both these scenario's are not taken care by the table component. Is there really no way to define a JRXML with dynamic columns?

Appreciate if you could share a tutorial/instructions or a sample web app which calls a JRXML report deployed on Jasper server via URL and then embeds the Jasper report viewer in a webpage.

I have created a Domain report(with table component and sub-reports) using the iReport Professional and is working fine. However I have a requirement to create different variations of this report with different column selection/sort/filter/group by. One of my options to start with was to create report with all the columns in the report and then based on runtime parameter trying to hide columns which don't need to be displayed (using Print When Expression) but this leaves blank columns. Not sure there is way to remove these blank columns. Additionally, this also does not solve my other problem of having to possibly based on runtime parameters change sort/filter/group by. The other option I was thinking was to some how get the JasperDesign Object java code generated from the JRXML. Based on that I can create multiple variations of the report (saw the No-XML design sample). I havn't seen any way I can generate the java code (Jasper Design) based on the JRXML? I was thinking to create mulitple reports programmatically based on the requirements. Could you please guide me how I can achieve my requirement to have these variations of the same base report with out having to create each time using the iReport professional?

I designed a domain and had numerous report created using it? At some point later needed to change the domain definition like adding new column, changing filter, updating column names etc. How will impact the existing reports? Will I need to redo all my existing reports?

Domain reports created using Table component need domain query to be defined manually by copying the xml instead of using a wizard. Users would need to be trained in doing so. Even the query filters need to be defined in xml (no easy way to say field is NULL for domain query filter string) Is there any easier way to do this since lot of our operations users will be using it?

Domain reports cannot be previewed in the IReport designer without publishing them to the server . This is slows down the user from checking the report changes with ease. Is there anyway to do this? Additionally, on previewing the domain report on the server if user needs to update. Currently looks like there seems to be no way to update the report. The report needs to be published again as a new report.

Datasource based reports can be Junit tested with appropriate mock data source implementation. But how can one Junit test Domain reports?

How can I have dynamic queries through Domain Query language in reports using Ireport designer? Looks like I can parameterize the queries but what if want to pass as parameter a fragment of the query including doing checks like is Null etc? I am looking to do this using Ireport designer.

How can I define a report in Ireport designer which based on certain input parameters can hide or display columns? I went through forums and see that most users are talking of using dynamic Jasper but we want this ability to be available to users designing reports through Ireport designer who not necessarily know programming.

How can I reuse parts of JRXML across reports like page header/footer etc? Jasper Community doesn’t talk much about it. The one link I found speak of some imports which tend to break Ireport designer interface. Is there a simpler way to do this without breaking Ireport desginer? http://community.jaspersoft.com/questions/534092/templates-reusing-jrxml-parts
