Why we need to provide Data adapter for reading attributes from Java Bean in Jasper studio?

[narayana.vr]

Unlike in Jasper I report 5.1.0, Jasper studio is not reading all the attributes from the bean after we provide the Name of the bean in the Dataset and Query editor dialog,

Pre requisite : we added the Jar file containing the classes to the Library through Add External Jars option provided in the Java Build Path of Project Properties Menu.

Jasper Studio Version : TIBCO Jaspersoft® Studio 6.6.0 

No Exception occurs and No attributes listed. Can any one face this situation Please do the Needful, Thanks.

Did you restart Jaspersoft Studio after adding the class?

I can't reproduce what you've mentioned.

[narayana.vr]

Yes Mr. Hozawa, we tried by re-starting the Jasper studio, still nothing happens.

We now Found the Exact problem which caused this situation.  There is vaadin frame work dependent jars missing, so added those dependent jars, now its listing the attributes.

but new problem is how to drill down to the inner most attribute of a nested class.

[hozawa]

JasperReports doesn't use vaadin framework. The problem seems local to your project.

Hozawa,  that problem was identified and resolved.

But new problem is how to drill down to the inner most attribute of a nested class. can you pls provide any solution for this. Thank you.
