Hi Rob,
You can add BIRT 2.3.1 Libraries using the below steps:
1) Right click on the project and select “Build Path–>Configure Build Path…”.
2) It will open Properties wizard for that particular project and right side you’ll find “Libraries” tab in between “Projects” tab and “Order and Export” tab. Select Libraries tab.
3) Click on “Add Library” button, It will open “Add Library” wizard.
4) Select “MyEclipse Library” and click “Next” button.
5) In the second page of Wizard, you’ll find all Libraries of MyEclipse, select “Report Web Library (MyEclipse 7.0 / BIRT 2.3.1)” by scrolling down or type “Report” in the text field available at the top.
6) check the check box of Library you want to add to the project and click “Finish” button.
Please let me know If you need anything else.
Thanks,
Chakri Vedula.
