 Hi Adia,

Hi have exactly the same problem. I run the put request in a REST extension in chrome and I have the same problem

Invalid resource descriptor


I am able to run other requests normally. Am I missing something?


Thank you!

I'll answer to myself,

I managed to run the report. I'll explain what I did. My report is called test.

I found valuable information here:



1. You must be previoulsy logged (there is a POST request for logging, see the manual) if not you must do basic authorization in each GET, PUT, POST request.


2. Run a GET request for getting the reportUnit source descriptor in XML




when this is done, the response is an XML file with the source descriptor for the report "test" (in this case).


3. Run a PUT request for generating the report



Here there is the keypoint that was causing the error: You have to copy the xml text (ENTIRELY) of the previous GET response into the body of the request


Optionally, you can add any parameter value by adding anywhere inside the wsType="reportUnit" environment


<parameter name="NAME">VALUE</parameter>


This is an example (only first lines) of a resource descriptor for tet report where the parameter "a" has been set to 2.

 <resourceDescriptor name="test" wsType="reportUnit" uriString="/reports/test" isNew="false">

        <parameter name="a">2</parameter>


The response contains the report UUID


<file type="application/pdf"><![CDATA[report]]></file>


4. Finally you have to run a get request to load the resulting report file. You hace to use the UUID provided in previous step




This can be done from any webbrowser, the report in pdf should load.


Hope it helps!!

 I am not sure I understand how to format the request body.  I am a bit of newb with this stuff and am working with creating a custom REST client in my Rails app.

I am able to get the resource for the report, but what exactly am I doing in the HTTP request to the report service with it?  Is it a field value that gets set in the put request?

 Hi Marco and cpuguy83,

I'm not an expert but I guess that you need to send HTTP comands through the net and manipulate responses. It depends on the language you use. For example, I'm using PHP, and I use curl for constructing and sending http commands (get and put).


Similar libraries should exist in other languages as Java.

So, what you need is to construct your GET command, send it and store the response. Then you have to include that response directly in the body of the PUT command,

Take a look to this thread. It also includes some wokring code in PHP.


If you do not modify the file descriptor, Jasperserver will create a report with default parameters (if any in the report). If you want to specify some values for the report you must modify the xml file descriptor using some XML manipulator library. For example in PHP take a look at:


I don't know for other languages but the pilosophy should be similar.

First of all I want to thank Sergio for his help, I followed the steps and that worked perfectly to export an HTML report. But when I tried to export a PDF one, the PDF downloaded is Blank. But the number of pages in that PFD file is the same as when I export the report in Ireport or Jasperserver.

Do you have an idea how to get the PDF report generated?
