passing params to custom datasource

2006-01-03 19:19

I have a custom datasource used by a subreport. I would like to pass the db connection string, username, and password to the main report as parameters, then pass them on through as method parameters to the custom datasource constructor, such as...

 

new customDS($P{connStr},$P{username}, $P{password})

 

when I do this, the parameters always come through to the constructor as null. If I hardcode them, everything works fine.

 

I'm using iReports 0.5.2 and JasperReports 1.1.1.

 

Thanks in advance!
