question about parameter usage

[juvenzh]

I'm using jasperserver to generate report. There are some existing  java library  in our system to  retrieve data. So I want to use JavaBean datasource or Custom Datasource  to wrap the existing library.

Now the question :when I create a datasource in jasperserver,  how to  pass  a parameter  to the datasource? or  pass parameter  to the bean method? for there are 50M reccords in the datasource ,  

can the static method to retrieve the JRDataSource   has parameters? such as  createDatasource($P{customerState})   ?

or the bean Method   like  get($P{customerState})    ?

or some other solution?

thanks
