How to Configure Chromium JS Engine to Download Reports in PDF Format - JasperReports Server V9.0.0 or V8.0.2
If you are using JasperReports Server V9.0.0 or V8.0.2, to download/export reports in PDF format, you must need to configure the Chromium JavaScript engine into the JasperReports Server.
Navigate to the <Jasper Installation Location>\apache-tomcat\webapps\jasperserver-pro\WEB-INF and open the js.config.properties.
Specify the chrome.path property value in the location for Chromium JavaScript engine to support the Chromium configuration.
Example: chrome.path = C:\\Program Files(x86)\\Google\\Chrome\\Application\\chrome.exe
For information about configuring Chromium in JasperReports Server, see the TIBCO JasperReports Server Administrator Guide > Configuring a JavaScript Engine for Graphical Report Rendering section.
