How to Generate PDF Report in Java
A PDF report generator is a software tool that allows users to easily and quickly create professional-looking reports in PDF format. This type of tool is particularly useful for businesses and organizations that need to create reports on a regular basis, such as financial reports, sales reports, or project status reports. With a PDF report generator, users can input data and information into a template, which is then automatically formatted into a polished and visually appealing PDF report. This can save a significant amount of time and effort compared to manually creating reports from scratch. Overall, a PDF report generator is an efficient and effective tool for creating professional-grade reports quickly and easily. There are many PDF Java libraries available to manipulate PDF using Java. In this article we will use IronPDF to create PDF reports.
1. IronPDF for Java PDF library
IronPDF for Java is a Java PDF library that allows developers to easily create, manipulate, and render PDF documents in their Java applications. With IronPDF, developers can generate high-quality PDFs from HTML, CSS, and JavaScript, as well as from other file formats such as images, Word documents, and Excel spreadsheets.
IronPDF is designed with simplicity and flexibility in mind, making it easy for developers to integrate PDF functionality into their Java applications. It provides a rich set of features, including support for adding text, images, and other media to PDF files, as well as the ability to add digital signatures, watermarks, and other security features. Additionally, IronPDF provides advanced PDF manipulation capabilities such as merging, splitting, and extracting pages from existing PDF documents.
2. Prerequisites
In order to Generate a PDF Report using IronPDF, there are certain prerequisites that need to be met. These prerequisites include:
- Java must be installed on your system, and its path must be set in the environment variables. If you haven't installed Java yet, you can download and install it from the official Java website link.
- An Integrated Development Environment (IDE) such as Eclipse or IntelliJ is required to write and execute your code.
- Maven, a build automation tool, should be integrated with your IDE to manage dependencies and build the project. If you're not familiar with Maven or need help integrating it with your IDE, you can refer to the official Maven website for guidance.
Once these prerequisites are met, you can proceed with setting up your project and using IronPDF to Generate PDF in your Java application.
3. IronPDF for Java Installation
To get started, open JetBrains IntelliJ IDEA and create a new Maven Java project.
Upon starting a new project in JetBrains IntelliJ IDEA, a prompt will appear in a new window, asking for the project's name and location. After entering a suitable name and location, you may proceed by clicking the "Finish" button.
Once you have clicked the "Finish" button, a new project will be opened in JetBrains IntelliJ IDEA, and you will be presented with the pom.xml file. This file will be used to add dependencies required for the Maven project.
Add the following dependencies in the pom.xml file.
<dependency>
<groupId>com.ironsoftware</groupId>
<artifactId>com.ironsoftware</artifactId>
<version>2024.3.1</version>
</dependency>After you have successfully added the above dependencies to the pom.xml file, you will notice a small icon appears in the top right corner of the file.
Simply click on this icon to install dependencies. This process should only take a few minutes, depending on the speed of your internet connection. After that create a new Java file or Java class files and start writing your code.
4. Create PDF Reports using IronPDF
With IronPDF, developers can quickly and easily create customized reports from a wide range of data sources, including databases, APIs, and other sources. One of the key benefits of using IronPDF for report generation is its ability to generate PDF reports from HTML. This means that developers can use familiar HTML and CSS markup to design their reports.
4.1. Create PDF Report from HTML
You can directly create a PDF report from HTML Report and save as PDF files at the same time using renderHtmlAsPdf method, this method takes HTML code as input and generates PDF instance as output. It uses the SaveAs method to save data as a new document at a specified location.
The source code is given below:
import com.ironsoftware.ironpdf.License;
import com.ironsoftware.ironpdf.PdfDocument;
import com.ironsoftware.ironpdf.Settings;
import java.io.IOException;
import java.nio.file.Paths;
public class main {
public static void main(String[] args) throws IOException {
PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("\n" +
"\n" +
"\n" +
"\tSample Report\n" +
"\t\n" +
"\t\tbody {\n" +
"\t\t\tfont-family: Arial, sans-serif;\n" +
"\t\t\tfont-size: 14px;\n" +
"\t\t}\n" +
"\t\ttable {\n" +
"\t\t\tborder-collapse: collapse;\n" +
"\t\t\twidth: 100%;\n" +
"\t\t}\n" +
"\t\tth, td {\n" +
"\t\t\tpadding: 8px;\n" +
"\t\t\ttext-align: left;\n" +
"\t\t\tborder-bottom: 1px solid #ddd;\n" +
"\t\t}\n" +
"\t\tth {\n" +
"\t\t\tbackground-color: #f2f2f2;\n" +
"\t\t}\n" +
"\t\th1 {\n" +
"\t\t\tfont-size: 24px;\n" +
"\t\t\tmargin-bottom: 16px;\n" +
"\t\t}\n" +
"\t\tp {\n" +
"\t\t\tmargin-bottom: 8px;\n" +
"\t\t}\n" +
"\t\n" +
"\n" +
"\n" +
"\tSample Report\n" +
"\tThis is a sample report generated with HTML.\n" +
"\t\n" +
"\t\t\n" +
"\t\t\t\n" +
"\t\t\t\tID\n" +
"\t\t\t\tName\n" +
"\t\t\t\tAge\n" +
"\t\t\t\tEmail\n" +
"\t\t\t\n" +
"\t\t\n" +
"\t\t\n" +
"\t\t\t\n" +
"\t\t\t\t1\n" +
"\t\t\t\tJohn Doe\n" +
"\t\t\t\t30\n" +
"\t\t\t\tjohn.doe@example.com\n" +
"\t\t\t\n" +
"\t\t\t\n" +
"\t\t\t\t2\n" +
"\t\t\t\tJane Smith\n" +
"\t\t\t\t25\n" +
"\t\t\t\tjane.smith@example.com\n" +
"\t\t\t\n" +
"\t\t\t\n" +
"\t\t\t\t3\n" +
"Mike Johnson\n" +
"40\n" +
"mike.johnson@example.com\n" +
"\n" +
"\n" +
"\n" +
"" +
"");
myPdf.saveAs(Paths.get("html_saved.pdf"));
}
}Just simply write HTML code directly in your Project, and it will generate a PDF file from it in an instant.
4.2. Create PDF Documents Report from RTF Code
Using IronPDF, you can also render RTF code using a Java program. Below is the sample code for converting RTF into PDF report. In this example we will use renderRtfAsPdf methods to render RTF code as a PDF instance and in the end use saveAs method to save PDFs.
import com.ironsoftware.ironpdf.License;
import com.ironsoftware.ironpdf.PdfDocument;
import com.ironsoftware.ironpdf.Settings;
import java.io.IOException;
import java.nio.file.Paths;
public class main {
public static void main(String[] args) throws IOException {
PdfDocument myPdf = PdfDocument.renderRtfAsPdf("{\\rtf1\\ansi\\deff0\n" +
"{\\fonttbl{\\f0 Arial;}}\n" +
"{\\colortbl;\\red0\\green0\\blue0;\\red255\\green0\\blue0;}\n" +
"\\pard\\plain\\fs24\\cf1\n" +
"\\cbpat8\n" +
"\\qc\\ul\\i\\cf2\\expndtw2\\charscalex120 Sample Report\\line\n" +
"\\ulnone\\i0\\cf1\\charscalex100\\expndtw0\\par\n" +
"\\pard\\plain\\fs18\\cf1\n" +
"This is a sample report generated with RTF.\\par\n" +
"\\par\n" +
"\\pard\\plain\\fs16\\cf1\n" +
"\\cbpat0\n" +
"\\qc\n" +
"{\\b Table 1: Sample Data}\\par\n" +
"\\par\n" +
"{\\pard\\plain\\fs16\\cf1\n" +
"\\qc\n" +
"{\\*\\shppict{\\pict\\pngblip\\picw98\\pich36\\picwgoal441\\pichgoal162\\hex5b5d5c5f5d5c5d5e5c5e5f5d5c5e5c5f5c5f5d5d5c5f5e5e5d5e5d5d5f5c5e5e5c5e5d5d5c5e5c5f5e5f5d5d5c5e5c5f5e5d5c5f5d5e5d5d5c5f5e5e5d5d5c5f5d5e5c5f5d5c5f5d5c5e5e5d5c5e5f5d5e5e5d5c5e5d5c5f5d5c5e5c5f5e5d5d5c5e5c5f5e5f5d5d5c5e5c5f5e5d5c5f5d5e5d5d5c5f5e5e5d5d5c5f5d5e5c5f5d5c5f5d5c5e5e5d5c5e5f5d5e5e5d5c5e5d5c5f5d5c5e5c5f5e5d5d5c5e5c5f5e5f5d5d5c5e5c5f5e5d5c5f5d5e5d5d5c5f5e5e5d5d5c5f5d5e5c5f5d5c5f5d5c5e5e5d5c5e5f5d5e5e5d5c5e5d5c5f5d5c5e5c5f5e5d5d5c5e5c5f5e5f5d5d5c5e5c5f5e5d5c5f5d5e5d5d5c5f5e5e5d5d5c5f5d5e5c5f5d5c5f5d5c5e5e5d5c5e5f5d5e5e5d5c5e5d5c5\n");
myPdf.saveAs(Paths.get("html_saved.pdf"));
}
}
