How to access a parameter in jrxml file and Print it?

Question

My query is, I have set a parameter in my java file like given below

Map<String, Object> parameters = new HashMap<String, Object>();
parameters.put("ReportTitle", "MRSG Quarterly Report");

How to access this in my jrxml file and Print it as a text?

Answer 1

You need to declare the parameter in your jrxml

 <parameter name="ReportTitle" class="java.lang.String"></parameter>

Then call it in a text field

<textField isBlankWhenNull="true">               
  <textFieldExpression class="java.lang.String"><![CDATA[$P{"ReportTitle"}]]>
  </textFieldExpression>
</textField>
