Abstract

A set of groupware portlets can be deployed on an enterprise portal in order to add groupware functionality thereon. The groupware portlets can provide an abstract user interface to groupware functionality provided by several collaboration servers and can also allow users to navigate to specific groupware functionality provided by a collaboration server. The portlets can connect to the various collaboration servers by implementing a personal messaging application programming interface. The interface can include a schema for defining groupware functionality and a set of providers for instantiating the connections to the various collaboration servers. The providers can be implementations of the schema that allow the groupware portlets to interact with the collaboration server. New schemas can be defined to extend existing schemas to enable more specific functionality provided by each collaboration server. The new schemas can be supported by the providers due to Java class inheritance.

Claims

1. A system for integrating groupware functionality into a portal, comprising:

one or more microprocessors;

a groupware portlet deployable on the portal, wherein the groupware portlet executes on the one or more microprocessors, and allows one or more users to access groupware functionality on the groupware portlet;

a plurality of collaboration servers, wherein each collaboration server provides the groupware functionality for the groupware portlet;

an application programming interface that includes a schema and one or more provider components,

wherein the schema defines the groupware functionality provided by the plurality of collaboration servers used at the groupware portlet,

wherein a particular one of the one or more provider components is used by the schema to interact with one of the plurality of collaboration servers to allow the groupware portlet to access the groupware functionality provided by the one of the plurality of collaboration servers, and

wherein each collaboration server is associated with one of the one or more provider components, and wherein each provider component is a specific implementation of the schema for one of the plurality of collaboration servers, and wherein the groupware portlet connects to any one of the plurality of collaboration servers via the schema by using one of the one or more provider components; and

wherein the groupware portlet switches from a first collaboration server of the plurality of collaboration servers to a second collaboration server of the plurality of collaboration servers for groupware functionality by replacing a first provider component associated with the first collaboration server, with a second provider component associated with the second collaboration server.

2. The system according to claim 1, wherein the schema includes an item class for representing entities on one of the plurality of collaboration servers and a container class for storing one or more items or other containers.

3. The system according to claim 2,

wherein the particular one of the one or more provider components implements a stub to create a connection to the one of the plurality of collaboration servers and to map method calls from the groupware portlet as defined by the schema to the groupware functionality provided by the one of the plurality of collaboration servers.

4. The system according to claim 1, wherein a new schema is implemented to extend the schema, and wherein the new schema exposes method calls that are specific to the groupware functionality in a particular collaboration server.

5. The system according to claim 4, wherein the application programming interface is further adapted to allow the one or more users to access the groupware functionality provided by the particular collaboration server as exposed by the new schema.

6. The system according to claim 1, wherein the groupware portlet makes WebDAV calls directly to one of the plurality of collaboration servers in order to access the groupware functionality.

7. The system according to claim 1, further comprising:

an intermediary collaboration service computer that receives HTTP calls from the groupware portlet and translates the HTTP calls to specific interface calls on one of the plurality of collaboration servers.

8. The system according to claim 1, wherein:

the groupware portlet connects to a virtual content repository adapted to manage and deliver content from multiple, heterogeneous repositories through a federated content management application programming interface.

9. The system according to claim 1, wherein:

the application programming interface is a personal messaging interface that is associated with a plurality of schemas, wherein the plurality of schemas are hierarchically related in a schema hierarchy, and wherein a developer can write code at any level of the schema hierarchy to allow the one or more users to access functionality at different levels of the schema hierarchy.

10. The system of claim 1, wherein the schema defines the groupware functionality using a hierarchy of items that includes one or more properties that are implemented as key-value pairs.

11. A computer implemented method for integrating groupware functionality into a portal, the method comprising:

deploying a groupware portlet on the portal, wherein the groupware portlet executes on one or more microprocessors and allows one or more users to access groupware functionality using the groupware portlet;

providing a plurality of collaboration servers, wherein each collaboration server provides the groupware functionality for the groupware portlet;

providing an application programming interface that includes a schema and one or more provider components;

defining, via the application programming interface, the groupware functionality using the schema, wherein a particular one or the one or more provider components is used by the schema to interact with one of the plurality of collaboration servers to allow the groupware portlet to access the groupware functionality provided by the one of the plurality of collaboration servers;

associating each collaboration server with one of the one or more provider components, and wherein each provider component is a specific implementation of the schema for one of the plurality of collaboration servers;

connecting the groupware portlet to any one of the plurality of collaboration servers via the schema by using one of the one or more provider components, wherein the groupware portlet switches from a first collaboration server of the plurality of collaboration servers to a second collaboration server of the plurality of collaboration servers for groupware functionality by replacing a first provider component associated with the first collaboration server, with a second provider component associated with the second collaboration server; and

allowing, via the application programming interface, the groupware portlet to access the groupware functionality provided by the second collaboration server.

12. The method according to claim 11, further comprising:

including in the schema an item class for representing entities on one of the plurality of collaboration servers and a container class for storing one or more items or other containers.

13. The method according to claim 11, further comprising:

implementing, via the particular one of the one or more provider components, a stub to create a connection to the one of the plurality of collaboration servers and to map method calls from the groupware portlet as defined by the schema to the groupware functionality provided by the one of the plurality of collaboration servers.

14. The method according to claim 11 further comprising:

implementing a new schema to extend the schema, and wherein the new schema exposes method calls that are specific to the groupware functionality in a particular collaboration server.

15. The method according to claim 14 further comprising:

adapting the application programming interface to allow the one or more users to access the groupware functionality provided by the particular collaboration server as exposed by the new schema.

16. The method according to claim 11 further comprising:

making WebDAV calls directly to one of the plurality of collaboration servers in order to access the groupware functionality.
