Abstract

An apparatus for assembling EJB components is provided. The apparatus includes a composite palette for browsing and managing the EJB components, and an architecture diagram editor module for dragging and dropping the EJB components shown in the composite palette or new component and connector icons to visually generate the architecture based on the C2 style. The apparatus further includes a component property editor module for describing properties and specifications of the EJB components in an architecture, and a glue code and composite EJB generator module for generating composite EJB component code and related glue code.

Claims

1. An apparatus for assembling EJB components, comprising:

a composite palette for browsing and managing the EJB components;

an architecture diagram editor module for dragging and dropping the EJB components shown in the composite palette or using the component and connector icons in order to visually build an architecture for a composite component according to the C2 style;

a component property editor module for setting the properties of EJB components in an architecture, and describing a component specification which has information about interfaces and behaviors of each EJB component; and

a glue code and composite EJB generator module for automatically generating composite EJB component code and glue code.

2. The apparatus of claim 1, wherein the composite palette browses and manages the EJB components (EJB packages) provided by a third party or in-house developed, architecture model files which are visually modeled, component specification files, and EJB wrapper files used as glue codes for converting the EJB components to C2 components, enabling the modeling of the architecture in the architecture diagram editor.

3. The apparatus of claim 1, wherein the architecture diagram editor module enables to assemble visually components into the architecture based on the C2 style by dragging-and-dropping the components selected from the composite palette, and check whether or not a syntax, a semantic and a topology of the architecture conform to the C2 style.

4. The apparatus of claim 1, wherein the component property editor module includes:

a property editor module for setting and showing a name of the component and component context information describing hierarchy information of the component in the architecture, link information on a component specification file which specifies interfaces and behaviors of the component with an Architecture Description Language, link information on an EJB wrapper file which is used as a glue code for converting the EJB components to C2 components based on the component specification information, and EJB package (Jar) information of the component; and

a specification editor module of the wizard type for being used to generate a specification file for describing interfaces and behaviors of the EJB components in the architecture.

5. The apparatus of claim 1, wherein the glue code and composite EJB generator module includes:

a glue code generator module for extracting the behavior information of the component from specification information built by an Architecture Description Language based on the C2 style and, then, automatically generating an EJB wrapper file that is used as a glue code for converting the EJB components to C2 components in the architecture based on the extracted behavior information; and

a composite EJB generator module for defining a home/remote interface of a composite EJB, designating the name of a new file by using a composite EJB interface editor module, and then automatically generating the home/remote interface, a session bean file and a bean glue code file of the composite EJB.

6. The apparatus of claim 4, wherein the specification editor module generates the specification file for describing interfaces and behaviors of each component if ‘

Top’

/‘

Bottom’

interface, method and behavior information of each component are inputted by a wizard.

7. The apparatus of claim 5, wherein the glue code generator module automatically generates the EJB wrapper file that is used as the glue code for converting the EJB components to C2 components in the architecture using the interface and behavior information of the component made by the specification editor, wherein said EJB wrapper file has a Request/Notification message processing logic for each component and a home/remote interface searching logic according to an application server to be used.

8. The apparatus of claim 5, wherein the composite EJB generator module includes:

a composite EJB interface editor module for generating the composite EJB for the whole architecture by providing a list of specification information on a bottommost component of the architecture in order to define the home/remote interface of the composite EJB, and for allowing the user to specify the file name to be generated; and

a composite EJB code generator module for creating the home/remote interface of the composite EJB, the session bean file, and a glue code file of a session bean for connecting the composite EJB to the architecture.

9. A method for assembling EJB components, comprising the steps of:

generating a new architecture diagram;

dragging an EJB jar from a composite palette and dropping the EJB jar to an architecture diagram editor;

editing the architecture diagram;

editing property and specification information of each component;

generating an EJB wrapper file for each EJB component using the edited property and specification information; and

generating a composite EJB for the architecture.
