Abstract

In accordance with embodiments, there are provided mechanisms and methods for sharing sessions between web-based applications. These mechanisms and methods can enable embodiments to provide sharing sessions between web-based applications. A method embodiment includes receiving a request to access a second web application from a user currently accessing a first web application. Session information from a first session between the user and the first web application is provided to a second session established between the user and the second web application. Access to the second web application is provided responsive to the user'"'"'s request, using session information from the first session.

receiving an invocation of the method to obtain session information at the sharable wrapper object,

returning session information from the session object associated with the session in response to said invocation, and

providing access to the different one of the plurality of web applications using the session information from the session object; and

wherein the user accesses the plurality of web applications using the session information from the session object.

2. The method of claim 1, wherein receiving during the accessing of the one of the plurality of web applications, a request to access a different one of the plurality of web applications comprises:

receiving, from a user currently accessing the one of the plurality of web applications, a request to access a different one of the plurality of web applications, the one of the plurality of web applications and the different one of the plurality of web applications associated with a common container.

3. The method of claim 1, further comprising:

establishing, from a viewpoint of the user, the sharable wrapper object with the different one of the plurality of web applications, the sharable wrapper object having context data from the session with the one of the plurality of web applications.

4. The method of claim 1, wherein providing the session information further comprises:

establishing inheritance by the sharable wrapper object of context data from the session.

5. The method of claim 1 wherein the one of the plurality of web applications and a different one of the plurality of web applications are disparate and unassociated web applications, and wherein the session is currently active.

6. The method of claim 1, further comprising:

looking up one or more objects directly within the sharable wrapper object of the different one of the plurality of web applications wherein said one or more objects are inserted during interactions with the session of the one of the plurality of web applications.

7. The method of claim 1, wherein the set of delegated methods include one or more of the following:

a method to obtain an object bound to the session, a method to obtain all objects bound to the session, a method to obtain a creation time of the session, a method to obtain an identifier assigned to the session, a method to obtain a last access time of the session, a method to obtain the maximum time the session will be open, a method to invalidate the session, a method to remove an object bound to the session, a method to bind an object to the session, and a method to specify a time between client requests before the session will be invalidated.

8. The method of claim 1, wherein the plurality of web applications are executing on one or more application servers.

9. A non-transitory computer-readable storage medium carrying one or more sequences of instructions for sharing sessions between web-based applications, which instructions, when executed by one or more processors, cause the one or more processors to carry out the steps of:

accessing one of the plurality of web applications on an application server by a user, wherein each of the plurality of web applications are disparate and unassociated web applications, and wherein upon accessing the one of the plurality of web applications a session and a session object are created, and wherein said session object stores session information associated with the session in a computer readable storage medium, and wherein the one of the plurality of web applications is designated as a parent web application for the session object;

receiving, during the accessing of the parent web application, a request to access a different one of the plurality of web applications by the user;

determining that the user has already established the session with the parent web application by a sharable session manager;

generating by the sharable session manager a sharable wrapper object associated with the session object of the parent application responsive to said request if the session has been determined to have already been established, said sharable wrapper object containing a method for obtaining session information and a set of delegated methods, and wherein the session information is accessible to each web application accessed by the user through the sharable wrapper object;

providing the session information from the session to the sharable wrapper object wherein the sharable wrapper object delegates all method invocations to the session object except for the method to obtain servlet context information, wherein if the method to obtain servlet content information is invoked, then the current context corresponding to the different one of the plurality of web applications that the session is being accessed in is provided to the client, otherwise if the delegated method to obtain session information is invoked, then providing the session information to the different one of the plurality of web applications includes

receiving an invocation of the method to obtain session information at the sharable wrapper object,

returning session information from the session object associated with the session in response to said invocation,

providing access to the different one of the plurality of web applications using the session information from the session object; and

wherein the user accesses the plurality of web applications using the session information from the session object.

10. The non-transitory computer-readable storage medium as recited in claim 9, wherein the instructions for carrying out the step of receiving during the accessing of the first web application, a request to access a second web application include instructions for carrying out the step of:
