Why do we need to use stateful mode in service package?Is there any particular usage of this?As we already have stateless.

Stateful mode exists for specific, session‑based integration scenarios where successive service calls must share the context.

can you please help with an example to explain me in layman’s term

When you need to maintain the requestor’s session and clipboard context across multiple, sequential service calls.

Real time example:

Think of a Shopping cart application where the service instance keeps the cart state for that user/session:

  • Add items to cart

  • Validate Shipment address

  • Process Payment

This is more natural when the interaction is ongoing.

Stateful is mainly needed when you want to maintain session/context across multiple service calls.

In stateless, every request is independent - no clipboard or session is retained. That’s why it’s preferred for most integrations.

Stateful comes into picture when:

  • You have multi-step interactions

  • Need to reuse clipboard data/auth context across calls

  • Or there is some conversation-based processing

In my opinion:
Use stateless by default. Go for stateful only if your use case truly depends on maintaining context
