You will find what you need there : http://community.jaspersoft.com/documentation/tibco-jasperreports-server-web-services-guide/v62/v2jobs-service

As well if SQL you can convert from the query + you have the choice with Java current casting methodology or using the JasperReports built-in functions for Date & Time in the expression Editor.

You can setup Oauth authentication from JasperReport Server side : http://community.jaspersoft.com/wiki/configuring-oauth-20-tibco-jasperreports-server-v61 Then depending on the way you embed JRS using APIs you will always find a way to use it.

community version?

You are not obliged to use a configuration file. But if you wish to , in your code you will need to use : https://github.com/Jaspersoft/jrs-rest-java-client#loading-configuration-from-file Or a manual way : https://github.com/Jaspersoft/jrs-rest-java-client#creation-of-manual-configuration It is pretty well explain in the readme of the github project...

What version of jasperreports server are you using ?

It is in the documentation, when you use the package manager to install Tomcat you need to define in the default_master.properties file of the buildomatic the following : # Tomcat app server root dir # appServerDir = C:\Program Files\Apache Software Foundation\Tomcat 7.0 # appServerDir = /home/devuser/apache-tomcat-7.0.26 # if linux package managed tomcat instance, set two properties below CATALINA_HOME = /usr/share/tomcat6 CATALINA_BASE = /var/lib/tomcat6

yes but I dont think you need the double quotes around the $P

Do you have the same Headers as POSTMAN ? URL properties as well? Did you configure the kind of request properly (POST, GET) ? Authentication as well?

Can you explain clearly what is the use case you want to setup !?

Try to use the "Print When Expression" properties of the reports components to display/hide them regarding conditions ie. parameters values .

You should find a way to pivot your data to get something like : Categorie;Value A;123 B;234 If using SQL , a CASE WHEN will do the Job.

Add "technical_specifications" as root node. Then inside nodes as fields.

If you want to use REST as a datasource : http://community.jaspersoft.com/project/web-service-data-source

You can use this plugin : http://community.jaspersoft.com/project/web-service-data-source If you need to process modification to data just use variables.
