Overview of a Report Unit

This documentation is an older version of JasperReports Server User Guide. View the latest documentation.

In the server, a report unit is the collection of elements used for retrieving data and formatting output. Anatomy of a Report Unit shows these elements:

•

The data source and the query that retrieves data for the report.

•

The main JRXML that determines the layout and is the core of the report unit.

•

The main JRXML defines other elements in one of the following ways:

•

Creating definitions internally

•

Referring to existing elements in the repository using the repo: syntax

•

The input controls and other resources.

For more information about the report unit, refer to the JasperReports Server Ultimate Guide.

Adding a Simple Report Unit to the Server

This section presents an example of uploading a JRXML to the server. The report only has two image resources. The example defines a custom query for the report unit.

To add the simple report unit to the server, you need access to the following sample data installed with the server:

•

<js-install>/samples/reports/AllAccounts.jrxml

•

<js-install>/samples/images/logo.jpg files
