What is JasperReports

JasperReports is a Java reporting tool used to write content to the printer, onto the screen, or into a variety of files like PDF, XLS, RTF, CSV, XML, HTML, ODT, and TXT. It is an open-source Java class library that adds reporting capabilities to Java-enabled applications such as Java EE or web applications to generate dynamic content. 

Introduction to Report Template 

In General, the layout that is adopted to generate reports by popular commercial reporting tools are as follows -

These were the elements present in the layout of commercial reports. Let us learn about them one by one. 

  • Title - This band appears only once at the starting of the report. It can be used by setting the attribute - isTitleNewPage='true'
  • page header - This element appears at the top of every page and may contain information on data, time, or organization name. It excludes the first page if the title band is used and the last page if this summary band is used with setting isSummaryWithPageHeaderAndFooter="false"
  • Detail - It specifies the entries of the specific fields that the column header lists.
  • ColumnHeader - It is used to list out the name of the specific fields like “Starting hour”, “Finishing hour”, “Author name”etc., depending upon what the user wants to display in the report.
  • ColumnFooter - It displays the summation of the listed field in the column header.
  • PageFooter - It is used to count and display the number of instant pages out of total pages.
  • Summary - It contains the concluded information from the "detail" element in a pie chart or graph to get a clear vision.

Lifecycle of JasperReports

Designing the report:

This is the first phase of the Jasper Report Lifecycle, where we have to create the JRXML file, an XML document that stores the definition of the report layout. We can use any text editor or report designer to create it manually. If we are using iReportDesigner, the layout will be designed visually, and therefore the real structure of JRXML can be ignored.

Compiling the report:

In this phase, the JRXML file created in the first phase is compiled, and a binary object with the .jasper extension is generated. Jasper files are shipped along with the application to run the reports

Executing the report:

In this step, data from the application is sent to the compiled report. A class called net.sf.JasperReports.engine.JasperFillManager offers the necessary functions to fill the data in the reports. Then a jasper print file is created, which can be used to print or export the report. 

Exporting the report to the desired format:

It is the last phase of the JasperReport lifecycle in which we need to export the Jasper print file using the class JasperExportManager. 

What are the Disadvantages of using JasperReports?

Here are some drawbacks of using JasperReports.

  • Editing the lines and creating the cross tabs is a very challenging task.
  • Making changes in any part of the package, such as removing features, it becomes difficult to again get to the default package setting.
  • JasperReports must be compiled first before they run, which forces developers to install the entire Java SDK.
  • Sometimes, after editing the report, it may show up different previews as unlike on the web.
