PHP uses PHP/JAVABridge to call JasperReport report _ PHP Tutorial

PHP calls the JasperReport report through PHPJAVABridge. This article describes how to use the PHP-Java-Bridge technology to output JasperReportweb reports. JasperReport (jasperge.org) is a powerful and flexible report generation tool that demonstrates how to use PHP-Java-Bridge technology to output JasperReport web reports.

JasperReport (http://jasperforge.org/) is a powerful and flexible report generation tool that displays rich page content and converts it to PDF, HTML, or XML format. This library is fully written in Java and can be used to generate dynamic content in various Java applications, including J2EE and Web applications.

The attached report design tool is iReport (free of charge). This tool can implement visual report design and output common reports in PDF, HTML, and WORD formats. the saved files are. jrxml suffix, which can run normally only in the Java environment. PHP cannot be called directly.

Since PHP cannot be called directly, it has to rely on PHP-Java-Bridge technology. See http://php-java-bridge.sourceforge.net/pjb/index.php for details

1. install tomcat. if you select the exe installation version, the jre environment will be automatically installed during installation. if it is a compressed version of tomcat, you need to install the java environment, which is more complicated to configure, install tomcat is recommended.

Configure tomcat Port 6000. the default port 8080 is occupied. The site root directory is webapps under tomcat.

2. download the php-java-bridge package.

3. install ireport3.0 (with updated version) copy all content in C: \ Program Files \ JasperSoft \ iReport-3.0.0 \ lib, copy to tomcat webapps/JavaBridge/WEB-INF/lib, these packages must be found by JavaBridge.

4. copy the java directory from the generated JavaBridge directory to the PHP site (or find php. in the ini file, change the allow_url_include parameter to on and directly reference java/java in JavaBridge. inc ). Download the report file http://www.rjohnson.id.au/download/jasper/test.jrxmland put it under the PHP site.

Create a PHP file under the PHP Site

Ireport. php (the port involved in the code should be changed according to your personal situation)
