I’m running a test using Apache+PHP, Tomcat and JavaBridge to try to load BIRT and render a document. This is the PHP file:

Once I access it through Apache+PHP i receive the following error:



Fatal error:  Uncaught [[o:Exception]:"java.lang.Exception:

127.0.0.1:8081 is Tomcat server. It seems it isn’t able to find “org.eclipse.birt.php.birtengine.BirtEngine” class. I copied birt-runtime-3_7_2/lib folder’s contents to JavaBridge’s WEB-INF/lib but it doesn’t help. I’ve tried searching for the answer on various sites, but the only one, I think actualy the same problem with no answer is here: LINK. Does anyone know a solution to this problem or how to make that JavaBridge would see that class?

  1. I’m not certain require_once takes URL as parameters. Have you tried an absolute path to the file instead? Mine looks like this: “C:/Program Files/Apache Software Foundation/Tomcat 7.0/webapps/JavaBridge/java/Java.inc” and it works.

    Also, you might want to look at this article which details the proper configuration steps:

    Anyway, best of luck to you, I know I lost quite a few hair when I had to do this configuration.
