PHP calls Jasperreport report via Php/java Bridge

This article is about using Php-java-bridge technology to implement the output of the Jasperreport Web report.

Jasperreport (http://jasperforge.org/) is a powerful and flexible report generation tool that can display rich page content and convert it to pdf,html, or XML format. The library is written entirely in Java and can be used to generate dynamic content in a variety of Java applications, including J2ee,web applications.

The accompanying report design tool is ireport (free), the tool can realize the visual report design, can output Pdf,html,word Common format report, save the file as. jrxml suffix, need the Java environment to be able to run normally, PHP cannot call directly.

Since PHP cannot be called directly, this has to be aided by Php-java-bridge technology. Refer to http://php-java-bridge.sourceforge.net/pjb/index.php for details

1, install Tomcat, if you choose EXE installation version, installation will automatically install the JRE environment, if it is compressed version of Tomcat, need to install another Java environment, configuration is more cumbersome, recommend the installation version of Tomcat.

The tomcat port is configured with 6000, the default 8080 port is occupied, and the site root directory is webapps under Tomcat.

2, download Php-java-bridge package, address http://php-java-bridge.sourceforge.net/pjb/ download.php, unzip after download, there is a Javabridge.war file, copy this file to Tomcat WebApps, after running http://localhost:6000/JavaBridge/, A Javabridge directory will be generated in WebApps.

3. Install ireport3.0 (with updated version) copy all contents of C:\Program files\jaspersoft\ireport-3.0.0\lib, copy to Tomcat webapps/javabridge/ web-inf/lib/, these packages need to be javabridge to find out.

4, from the generated Javabridge directory to copy the Java directory under the PHP site (or find php.ini this file, the Allow_url_include parameter is changed to ON, directly refer to Javabridge under the Java/java.inc). Download the report file Http://www.rjohnson.id.au/download/jasper/test.jrxml under the PHP site.

Then build a php file under the PHP site

Ireport.php (the code is related to the port, you need to change according to personal circumstances)

5, visit PHP site, http://localhost:8080/ireport.php, you can export PDF documents.
