How can I pass an arbitrary object to jasper report as parameter?

Question

I would like to pass as a parameter to my .jrxml an arbitrary object of my domain, e.g a Person.

InputStream reportFile = MyPage.this.getClass().getResource         


        

Answer 1

Yes, it is possible exactly the way you explained. Just make sure you have the correct classpath when compiling the jrxml and be careful with the case - either lowercase (person) or uppercase (PERSON) in all places.

Answer 2

Yes, you can pass any Java object, but you should make sure to import that object in the JRXML.

Inside the jasperReport tag. You can use the tag import, like:

 <jasperReport...>
      <import value="org.justfortest.Person">

However, you can use JRBeanCollectionDataSource and populate the report with a list of your object, without needing to store arbitrary objects in the params map.
