These topics provide information about developing WebSphere application components to use transactions

The way that applications use transactions depends on the type of application component, as follows:

A session bean can either use container-managed transactions (where the bean delegates management of transactions to the container) or bean-managed transactions (component-managed transactions where the bean manages transactions itself).
Entity beans use container-managed transactions.
Web components (servlets) and application client components use component-managed transactions.

Use the following tasks to develop WebSphere application components that use transactions:

Configuring transactional deployment attributes. This task determines whether EJB components use container- or bean-managed transactions by setting an appropriate value on the Transaction type deployment attribute. You can also configure other transactional deployment descriptor attributes.
Using component-managed transactions. If you want a session bean, Web component, or application client component to manage its own transactions, write the code that explicitly demarcates the boundaries of a transaction. There are some limitations to the transaction support available to application client components, as described in Client support for transactions
