Ans: Life cycle management is a service that one must take from application server for the EJB components. That's why the programmer will never define any method related to life cycle management of the EJBs. But then he/she has to declare those methods and let the ejb container implement the same. Home interface is used for declaring such methods. Ex: crate, find, remove etc. The reason that we need to declare these methods is to specify the list of input and output parameters. See similar questions...

The main reason is because there is a clear division of roles and responsibilities between the two interfaces. The home interface is your way to communicate with the container, that is that is responsible of creating, locating even removing one or more beans. The remote interface is your link to the bean that will allow you to remotely access to all its methods and members. See similar questions...

The principal difference is that an abstract class is used when you have a type/subtype relationship. An interface does not imply a type/subtype hierarchy; it merely forces a class to have some methods with a given signature. That allows some other code to rely on being able to call those methods. You want to subclass abstract classes when you are making subtypes that define the abstract behavior. The subclass should have a "kind of" relationship to the superclass. See similar questions...

A Cluster is very similar to a Context. There are certain operations found in a Context that are not relevant to a Cluster. For example, it doesn't make sense binding a context to a Cluster. A Cluster is supposed to contain a set of object references, not contexts. However, a Cluster interface shares many of the same operations with the Context interface, such as bind, rebind, resolve, unbind and list operations. This common set of operations pertains to operations on a group. See similar questions...

The two GISMO interfaces contain different data products. The Pathfinder Interface contains the NASA gridded Polar Pathfinder data sets (SMMR, SSM/I, AVHRR, and TOVS). The SNODAS Interface contains the Snow Data Assimilation System (SNODAS) Data Products at NSIDC data set. See similar questions...

V5.1 uses only one 2.048 kbit/s link whereas V5.2 may use up to sixteen (16) 2.048 kbit/s links on one interface. V5.1 does not support concentration whereas V5.2 is inherently designed to support it using a dedicated protocol known as the Bearer Channel Connection (BCC) protocol. V5.1 does not support ISDN primary rate access user ports whereas V5.2 does. V5.1 has no concept of communication channel protection whereas this function is available for V5.2 when that particular V5. See similar questions...

Most distance learning specialists recommend that your course be complete on the day the course starts. This gives students the sense of your course as a whole. It also allows you to participate fully with the students rather then trying to plan your next lesson. There are many options and resources available in an online asynchronous environment to provide a rich learning experience for your students. See similar questions...

Handcrafted log homes are limited to single stories due to shrinking issues. A handcrafted log home is much more natural looking than a milled log home and is generally a little more costly for the initial shell. To learn more about handcrafted log homes click here. Milled or machine built log homes are generally built from dead standing timber and are therefore not subject to as much shrinking. See similar questions...

Appraisal & a Professional Home Inspection are both completely different evaluations of the property. The appraiser establishes an estimated 'market value' of the property; comparing it to similar homes within the listing neighborhood. While a Real Estate Inspector evaluates the actual physical condition of the structure and all of the related components of the house that you are buying. See similar questions...

LabPro has all the features of our Universal Lab Interface (ULI) and many more. It features automatic sensor recognition with six independent channels: four analog and two digital. LabPro can be used with a computer or a TI graphing calculator. It can also be used as a stand-alone data logger. When used with a computer, it can be connected to the serial port or a USB port. It collects data faster than our ULI and supports analog output. LabPro is also less expensive than the ULI! See similar questions...

a general rule, we follow native MS Windows conventions as much as possible. 21.4 is a fairly complete Windows application, supporting native printing, system file dialog boxes, tool tips, etc. In cases where there's a clear UI conflict, we currently use normal Unix XEmacs behavior by default, but make sure the MS Windows "look and feel" (mark via shift-arrow, self-inserting deletes region, Alt selects menu items, etc. See similar questions...

per the specifications, there can be 'ZERO' or 'MORE' create() methods defined in an Entity Bean. In cases where create() method is not provided, the only way to access the bean is by knowing its primary key, and by acquiring a handle to it by using its corresponding finder method. In those cases, you can create an instance of a bean based on the data present in the table. All one needs to know is the primary key of that table. I.e. See similar questions...
