Using dynamic pojos to generate BIRT reports at runtime?

dj-method-x

I have an RCP application where a user basically fills out a form and clicks a save button. When they click the save button I want to generate a birt report.
 
How can I accomplish this?
 
Right now I create a pojo model object that contains all of the form data that the user has entered as strings.
 
I have a report designed using a table.
 
Right now I am trying to use a ScriptedDataSetEventAdapter implementation to generate the data in the report by overriding the fetch method and assigning values using the pojo to each column of each row.
 
But my problem is that I have no way of getting the pojo to my ScriptedDataSetEventAdapter implementation. 
 
I have another class that sets up the Report Engine, opens the report design, and runs the report. This class gets has the pojo, but I cannot figure out how to get the pojo to my ScriptedDataSetEventAdapter implementation since it seems like this class is instantiated and called from the report design.
 
Is there an easier way to do what I'm trying to describe?

You could use the Design Engine API (DEAPI) to create and/or modify the report design.
 
Take a look over this documentation on DEAPI: <a data-ipb='nomediaparse' href='https://www.eclipse.org/birt/documentation/integrating/deapi.php'>https://www.eclipse.org/birt/documentation/integrating/deapi.php</a>

I already have a report design. All I want to do is pass the table the data that's in the pojo. I shouldn't have to change the design of the report to do this right?

i do provide my data via a scripted data source from my dynamic pojo's. (the pojo data source did not work for my purpose)
i doubt that you do need to change the report. i'd just change the way the data gets in (scripted data source)

I overlooked the fact that ScriptedDataSetEventAdapter has a beforeOpen method that has a ReportContext as a parameter. I was able to inject a map containing all of my form data into my AppContext and then I get the AppContext from the ReportContext. From there I just loop through everything and assign the row column data. Pretty simple stuff

do you use birt in an OSGi Service?
because i do something similar and run into problems see <a data-ipb='nomediaparse' href='http://developer.actuate.com/community/forum/index.php?/topic/36280-birt-osgi-service-problem-bug/'>this thread</a>
could you check if you do it the same way and let me know if you have the same problem?
 
if you do not have this problem could you create a small example (alter mine?) which demonstrates how you do it?

This actually will be in an OSGI bundle, but is not yet. If I have problems I will report back and let you know!

lumo

please also report back if you got it working, because i got the problem that generating the report does not work (though preview works without problems) probably you 'solve' my problem just by posting how you did it. (code)
 
thanks!
