Here’s the translation of your request into English:

For example:
`java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDataSource`
```java
public class Task {
private Long id;
private String desc;
@ManyToOne
private Role role;
}
public class Role {
private Long id;
}
```
My question is, how can I perform a paginated query for tasks under a specific role based on the `role` ID? I referred to the Hibernate official documentation but couldn't find a solution. It seems like an issue related to reading or writing protected memory.

### Solution Proposals:
#### Solution 1:
Is this what you're asking about?
`from Task s where s.role.id = :roleid`
---
#### Solution 2:
It's recommended to define a `one-to-many` relationship in the `Role` class. This way, it will be much easier to query role information using the `roleid` and retrieve all associated tasks as a set. If you stick with the original design, you can use projection queries instead. I hope this helps you.
