Using JRMapCollectionDataSource

[yapkm01]

In short:

1. Master report has 1 subreport.

2. The master report has 1 field (hashmap). This field in ireport equivalent to the pojo java program as shown below:

private HashMap <String, Object> reportingType = new HashMap <String, Object>();

3. I need to pass this field reportingType to the subreport and use is in the subreport.

4. In the master report under data source expression, i used JRMapCollection new

net.sf.jasperreports.engine.data.JRMapCollectionDataSource ($F{reportingType}.values())

Questions:

How do i access that $F{reportingType} in the subreport? I dont find much information on the usage of JRMapCollectionDataSource. Please advice.

Hi yapkm01,

I know it has certainly been a while now... Nonetheless, I wanted to know if you were able to find out how to access the $F{reportingType} in the subreport?

If so, could you please tell me how you managed to do it?

 

Thank you so much for your advice in advance...
