How to call jasper API and set employee object to parameter?

Perhaps try using the Employee object as a JavaBean datasource?

To send an object as a parameter, you have to:

• Define the parameter name and the type of the object in the .jrxml file
• Send a Map with the parameter HashMap parameters = new HashMap<>(); parameter.put("object", new Object());
• In the .jrxml file you can use the parameter as following: <textFieldExpression><![CDATA[$P{object}.getValue()]]></textFieldExpression>

It works for me
