hello,
i want to create a birt report with a simple java application.
i found some code examples on the internet but my problem is, how do i use the classes and methods?
i thought there would be a libary (jar-file) which i have to include,
but there is not (or i just did not found it)
is there an other way how to include the classes and methods which i need to create a birt report in a java project?
thx!

BTW the code sample was for BIRT 3.7.
