Problem - Wrong selection of jdbc driver on spagoBI-studio side

Solution -
create datasource with correct driver

In my case
1. i create datasource with option selection ""JDBC database connection with query builder""
2. Deployed BIRT report from studio to server
3. when execute report from server side
it throws above error
4. i deleted the data source created in step 1
5. recreate data-source with option "JDBC Data Source"
6. need to recreate dataset
7. deploy it again
