## 6. Integration with Existing Code

### 6.1 Modifying Smb2CreateRequest
```java
// In Smb2CreateRequest.java
public void addLeaseContext(Smb2LeaseKey key, int requestedState, boolean isV2) {
    Smb2LeaseContext leaseContext = new Smb2LeaseContext();
    leaseContext.setLeaseKey(key);
    leaseContext.setLeaseState(requestedState);
    if (isV2) {

                createReq.addCreateContext(reconnectCtx);
                
                // Add lease context if associated
                if (info.leaseKey != null) {
                    createReq.addLeaseContext(info.leaseKey, 
                        Smb2LeaseState.SMB2_LEASE_NONE, false);
                }
                
                // Send create request
