```
public class ClientSession
extends org.eclipse.persistence.internal.sessions.AbstractSession
```
Purpose: Acts as a client to the server session.
Description: This session is brokered by the server session for use in three-tiered applications. It is used to store the context of the connection, i.e. the login to be used for this client. This allows each client connected to the server to contain its own user login.
Responsibilities:
- Allow units of work to be acquired and pass them the client login's exclusive connection.
- Forward all requests and queries to its parent server session.
This class is an implementation of Session. Please refer to that class for a full API. The public interface should be used.

    INTERNAL: Execute the call on the correct connection accessor. Outside of a transaction the server session's read connection pool is used. In side a transaction, or for exclusive sessions the write connection is used. For partitioning there may be multiple write connections.

  - getAccessor
```
public org.eclipse.persistence.internal.databaseaccess.Accessor getAccessor()

    INTERNAL: This should normally not be used, getAccessors() should be used to support partitioning. To maintain backward compatibility, and to support certain cases that required a default accessor, if inside a transaction, then a default connection will be allocated. This is required for sequencing, and JPA connection unwrapping, and ordt mappings. Outside of a transaction, to maintain backward compatibility the server session's accessor will be returned.

```
    INTERNAL: Returns the appropriate IdentityMap session for this descriptor. Sessions can be chained and each session can have its own Cache/IdentityMap.

    Overrides:
    
    getParentIdentityMapSession in class org.eclipse.persistence.internal.sessions.AbstractSession
    
    Parameters:

    getProperty in class org.eclipse.persistence.internal.sessions.AbstractSession
  - getExecutionSession
```
public org.eclipse.persistence.internal.sessions.AbstractSession getExecutionSession(DatabaseQuery query)
```
    INTERNAL: Gets the session which this query will be executed on. Generally will be called immediately before the call is translated, which is immediately before session.executeCall.
    Since the execution session also knows the correct datasource platform to execute on, it is often used in the mappings where the platform is needed for type conversion, or where calls are translated.
    Is also the session with the accessor. Will return a ClientSession if it is in transaction and has a write connection.
    
    Overrides:
    
    getExecutionSession in class org.eclipse.persistence.internal.sessions.AbstractSession
