Module 09: Session Resume

Load and resume existing sessions.

What You’ll Learn

Using client.loadSession() to resume a session by ID
LoadSessionRequest and LoadSessionResponse structure
Session state persistence across load operations

How It Works

loadSession() tells the agent to resume a previously created session. The agent looks up its stored state for that session ID and restores the conversation context. Whether state actually persists depends on the agent implementation — the demo includes a StatefulAgent that stores session history in a ConcurrentHashMap.

The Code

This example creates a session, sends messages to build history, then loads the same session by ID. After loading, the agent has access to the previous conversation context:

// Create a session and send some messages
var session = client.newSession(new NewSessionRequest(".", List.of()));
client.prompt(new PromptRequest(session.sessionId(),
    List.of(new TextContent("Remember: my favorite color is blue."))));

// Later: resume the same session by ID
var loadResponse = client.loadSession(
    new LoadSessionRequest(session.sessionId(), ".", List.of()));

// Continue the conversation with context preserved
client.prompt(new PromptRequest(session.sessionId(),
    List.of(new TextContent("What is my favorite color?"))));
// The agent remembers the previous conversation
