Birt + Java class

Migrateduser

<p>hello,<br><br>
I wish to make a call to a Java classes from my BIRT Interface .<br><br>
But this class will not change the report.<br><br>
My report correspond to lines of information contained in the database ,including a field LIEN_XML.<br><br>
My Java class take in parameter the link to an XML file, who correspond to the value of the button i clicked.<br><br>
The class will transform the XML file with an XSL stylesheet, and create an HTML file .<br><br>
Then the class will be used to open this HTML File With Desktop.browse .<br><br><br>
My Java class Works wonderfully , but I can not make the connection between BIRT and class.<br><br>
I saw the existence of class events manager which could maybe correspond to my expectations .<br><br>
But despite of my research, I can not find any good informations about his use.<br><br>
Things I 'd like to know :<br><br>
-Do you have any links to good tutorials on the class event manager?<br>
-Do you know how to do what I am looking for ? (If so,do you have a little time for an explanation ? )<br><br>
Best regards,<br>
