JavaDoc for BIRT Report Engine

OneWorld

Hey there,<br />
<br />
I am used to develop software in Eclipse with integrated JavaDoc. When hovering over methods, a description will pop up. That speeds up development a lot.<br />
<br />
Unfortunatly I Code descriptions weren't included in the files I downloaded from: <a class='bbc_url' href='http://download.eclipse.org/birt/downloads/build.php?build=R-R1-2_6_2-201102191842'>http://download.eclipse.org/birt/downloads/build.php?build=R-R1-2_6_2-201102191842</a><br />
<br />
<ul class='bbc'><li><a class='bbc_url' href='http://www.eclipse.org/downloads/download.php?file=/birt/downloads/drops/R-R1-2_6_2-201102191842/birt-runtime-2_6_2.zip'>runtime (report engine, that I need)</a></li><li><a class='bbc_url' href='http://www.eclipse.org/downloads/download.php?file=/birt/downloads/drops/R-R1-2_6_2-201102191842/birt-report-framework-sdk-2_6_2.zip'>report framework sdk (supposedly with doc)</a></li></ul>
<br />
I tried both (added all JARs to build path). However, in the Pop Ups it still says "Note: This element neither has attached source nor attached Javadoc and hence no Javadoc could be found."<br />
<br />
Any help? Thank you!
