Hi gabri,

Your problem is in the jrxml file with the definition of the fields. You have created three fields but no description is defined for them so the report does not know where to get the values from. and it shows null. I made the following modification in the definition of the fields:

 <field name="nombre" class="java.lang.String">
    <fieldDescription><![CDATA[nombre]]></fieldDescription>
  </field>
  <field name="edad" class="java.lang.String">
    <fieldDescription><![CDATA[edad]]></fieldDescription>
  </field>
  <field name="domicilio" class="java.lang.String">
    <fieldDescription><![CDATA[domicilio]]></fieldDescription>
  </field>

I have tried it with your source code and it works ok. I attach the corrected jrxml file.

Hope this helps

Regards.

OH!!! Thank you very much. It is working.

 

the problem then was when I made the jrxml file with IReport tool.
