I have resolved this issue by adding jar file path.

Now I have created JRXML with static and dynamic fields

Outline -> Right Click and choose Dataset and Query Dialog -> Java Bean tab -> Enter the class name which holds fields name

Fields are not listing out and its showing as Class not found: com.xxx.StudentScore

Can anyone help me to list out the fields

Hi,
can you please give a look at the following discussion: https://community.jaspersoft.com/questions/1072651/i-cannot-read-java-bean-data-source-jar
There is a similar issue, moreover it is strongly adviced to move to JSS 6.4.3 (recently released) that contains improvements in terms of classpath handling.

Regards,
Massimo.
