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.
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'
PageHeader - 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 columnHeader 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 ColumnHeader.
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.

A report is designed and created using the below-mentioned steps -
Step 1. Create JRXML file in Jaspersoft studio
Ste2. Selecting the desired template.
Step3. Selecting a parent folder.
Step4. In the Data Source window, tap on "New" button and create a new data adapter.
Step5. Select a data adapter.
Step6. Fill up data adapter details and select factory class.
Step7. Enter the prefix or pattern.
Step8. Define the factory class and add the path to jar files.
Step10. Congratulations! You are done with adding all important report creation information successfully. Now, click on the "Finish" button.
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 iReportDesigner 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.
In this phase, the JRXML file created in the first phase is compiled, and a binary object with .jasper extension is generated. Jasper files are shipped along with the application to run the reports
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.
It is the last phase of JasperReport lifecycle in which we need to export the Jasper print file using the class JasperExportManager.
Here are some drawbacks of using Jasper Reports.
