I m using tibco jaspersoft studio to generate a report

droping fields in the detail band is getting all data but when I try to use a table I m getting two empty pages.

the printing option is set to print all sections no details

here is my data json file

 "clientName" : "SEMMOUD Abderrazak",
 "clientPhone" : "043303854",
 "codeExterne" : "CLI201801",

What should I do to fix this issue?

Your table dataSet is not actually linked to any data, at runtime. A quick fix is to:

1. Export your JSON Data Adapter to a file on the same level as your report, let's say refcliJsonAdapter.xml
   


2. 
   

   Add the net.sf.jasperreports.data.adapter property to your table dataSet, something like:

   
   
   

   <subDataset name="jsonRefClient" whenResourceMissingType="Empty" uuid="1dcb37f4-96e4-472a-aadb-309de9d05089">
    ...
    <property name="net.sf.jasperreports.data.adapter" value="refcliJsonAdapter.xml"/>
    ...
   </subDataset>
   

   
   



3. Preview the report against the One Empty Record built-in Data Adapter if you don't want repeating tables.
