How to call report that have data sources other than jdbc

[hossam-houssien]

some times we need to have json or xml data source into jasper report, which we can do, however we can't find a way to call such report from JasperReportsIntegration

here is an example report

<?xml version="1.0" encoding="UTF-8"?>

</jasperReport>

in above example there is variable $P{jsonSource} which have a default value for a path of a .json file like test.json

the data in json file (for the example) is

{
"name":"hossam",
"id":45
}

when we run this example in jasperdoft studio v6.1.1, it works fine.

we can't find a way to deploy it to JasperReportsIntegration (in reports dir) , each time we try to call it from the test page (removing the datasource name value) it gives:-

Could not connect via JDBC: IO Error: The Network Adapter could not establish the connection

Is there any way to bypass the name of the data source, so it pick up the provided in report? or is there a way to configure and use another data source type?

we are using JasperReportsIntegration v 2.4.0.0

Interesting.

This use case was never intended. The main use case is to use an Oracle database connection. But you can also connect to any JNDI data source, here you can connect to other (mostly) sql databases. You configure that directly in Tomcat.

In your case I would probably:

• set up a dummy Oracle connection with a query like select null from dual or something similar.
• create a second data source in the same report and use $P{jsonSource} as the data source there.

Something along those lines.

The use case is interesting, I like the idea of passing the data via xml or json directly to the report engine.
