Difference Between Session and Entity Beans

Difference Between Session and Entity Beans: "The EJB specification supports both transient and persistent objects. A transient object is referred to as a session bean, and a persistent object is known as an entity bean."

Difference Between Stateful and Stateless Session Beans

Difference Between Stateful and Stateless Session Beans: "Session beans can either be stateful or stateless. With stateful beans, the EJB container saves internal bean data during and in between method calls on the client’s behalf. With stateless beans, the clients may call any available instance of an instantiated bean for as long as the EJB container has the ability to pool stateless beans. This enables the number of instantiations of a bean to be reduced, thereby reducing required resources."

if, if...else and switch statements in C with samples

if, if...else and switch statements in C with samples: "The if..else statement is a two way branch: it means do one thing or the other. When it is executed, the condition is evaluated and if it has the value `true' (i.e. not zero) then statement1 is executed. If the condition is `false' (or zero) then statement2 is executed. The if..else construction often saves an unnecessary test from having to be made."

Formatting with printf in C

Formatting with printf in C: "We could right justify our output using the format specifiers. The field-width specifier tells printf( ) how many columns on screen should be used while printing a value(as in %wd),here the value is right justified and is padded with blanks on the left.

RMSCookieConnector - Using Cookies in J2ME

RMSCookieConnector - Using Cookies in J2ME: "The RMSCookieConnector class stores cookies in an RMS record store. An RMS record store is accessed by its name, rather than reference, and can persist between soft resets, or reboots. That ensures an old session remains valid when a user later returns to an application after previously quitting it. Considering most people use their mobile information devices for many different tasks simultaneously, cookie persistence is a desired feature."

Datagrams in J2ME (UDP Programming sample)

Datagrams in J2ME (UDP Programming sample): "It is quite possible for someone to have worked with Java for some time without ever needing to understand or use datagrams. For mobile devices, however, datagrams offer some advantages in that they are rather lightweight when compared to TCP-based connections such as sockets. User Datagram Protocol, UDP, is one of the more common datagram protocols. However, because most datagram protocols follow the same basic principals as to their usage, the GCF is able to support datagrams generically."
