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.
There are many reasons for using a Jasper report tool:
Here are significant features of the JasperReports tool:
Step1. Click on "Download Now" option to install the JasperReports Community edition
Step2. Select Jaspersoft Studio CE
Step3. Click on the Download button
Step4. After that, the given screen will appear; select I agree button
Step5. Then click on the install button
Step6. Once the download is done, tap on the finish button
Step7. Then click on the get started option and start working.
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 the "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 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.
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
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 the JasperReport lifecycle in which we need to export the Jasper print file using the class JasperExportManager.
Here are some drawbacks of using JasperReports.
