Custom datasource parameters

2003-12-30 22:57

Could anyone provide a suggestion on how to deal with this...

 

I am using a custom datasource returning a JRDatasource. It works fine. What bothers me is that I have to create a new Datasource in the Connections/Datasources window for each new Report that I have. What I would rather have is one JRDatasourceFactory, to which I can pass some parameters when the report is generated.

 

For example, for direct JDBC datasources, I set up one datasource to a particular database. Then, for each report, I just re-use the datasource, and use a different query. However, for the custom datasource, I really can't do that. I was wondering if anyone has tried passing parameters to the DataSourceFactory method that returns the JRDatasource.

 

Any suggestions ? I am willing to implement such a feature in iReports if it is not already there...

 

 

Thanks in advance,

 

Alex K

Alex, I'll be happy if you implements a special connection that can be driven using a set of parameters. iReport implements only a proof of concepts of this feature that you have sufficently understood...

I would thinks this functionality already exist somewhere, just a matter of how to say it. I have the same problem. A custom DataSource, and in iReport I create some new report PARAMETERS:

*METHODNAME

*METHODVARIABLE1

*METHODVARIABLE2

...

I have those parameters defined, but what methods would one use from iReport to get those PARAMETER values? Misc.nvl()?

Hi Alex,

 

I am in front of the problem you described. I have seen in the cource code and i think that the problem is inside the method JRCustomDataSourceConnection.getJRDataSource.

Could you tell me if i am on the right way and if you succeed to implement this feature in iReport ?
