Abstract

In accordance with an embodiment, described herein is a system and method for determination of partition identifiers in an application server environment. An exemplary method can begin with providing, at one or more computers, including an application server environment executing thereon, together with a plurality of deployable resources which can be used within the application server environment, one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain, and a component invocation context manager, the component invocation context manager comprising a stack. The method can set one or more component invocation contexts. The partition-aware container can perform one of registering or looking up a current component invocation context at the component invocation context manager. The current component invocation context can be associated with a current partition. The method and system can be utilized in multitenant as well as non-multitenant application server environments.

a plurality of deployable resources which can be used within the application server environment, and

one or more partitions including a targeted partition, wherein each partition provides an administrative and runtime subdivision of a domain, and is associated with a partition identifier, and wherein the targeted partition defines values of configuration data for a collection of the deployable resources for use with the targeted partition, and binds the collection of deployable resources to the defined values for use with the targeted partition;

a partition-aware container that determines that a target resource of a request is included in the collection of deployable resources of the targeted partition, and sets a component invocation context that is associated with the partition identifier of the targeted partition;

a component invocation context manager, the component invocation context manager including a stack for maintaining component invocation contexts;

wherein the partition-aware container performs one of registering the component invocation context that is associated with the partition identifier of the targeted partition by pushing the component invocation context that represents the request onto the stack, or looking up a current component invocation context at the component invocation context manager by requesting the current component invocation context from the stack.

2. The system of claim 1, wherein registering the component invocation context that is associated with the partition identifier of the targeted partition comprises:

receiving, at a front end component, the request including target information, the target information indicating the targeted partition; and

wherein pushing the component invocation context that is associated with the partition identifier of the targeted partition onto the stack includes making a call, by the partition-aware container, to an application programming interface of the component invocation context manager.

3. The system of claim 2, wherein the partition-aware container is configured to, after registering the component invocation context that is associated with the partition identifier of the targeted partition at the component invocation context manager, and upon completion of the request, unregister the component invocation context that is associated with the partition identifier of the targeted partition at the component invocation context manager, the unregistering comprising:

unregistering, by the partition-aware container via the application program interface, the component invocation context that is associated with the partition identifier of the targeted partition at the component invocation context manager.

4. The system of claim 1, further comprising

a work manager,

wherein registering the component invocation context that is associated with the partition identifier of the targeted partition at the component invocation context manager by the partition-aware container comprises passing instructions by the partition-aware container to the work manager to register the component invocation context that is associated with the partition identifier of the targeted partition at the component invocation context manager.

5. The system of claim 1, wherein looking up the current component invocation context comprises:

setting, as the context within the partition-aware container, the current component invocation context.

6. The system of claim 1, wherein the targeted partition is a global partition, the global partition being associated with the domain.

7. The system of claim 1, wherein the application server environment comprises a multi-tenant application server environment, and wherein the system can associate the one or more partitions with a tenant, for use by the tenant.

8. A method for determination of partition identifiers in an application server environment, comprising:

providing, at one or more computers, an application server environment executing thereon, together with

a plurality of deployable resources which can be used within the application server environment,

one or more partitions including a targeted partition, wherein each partition provides an administrative and runtime subdivision of a domain, and is associated with a partition identifier, and wherein the targeted partition defines values of configuration data for a collection of the deployable resources for use with the targeted partition, and binds the collection of deployable resources to the defined values for use with the targeted partition, and

a component invocation context manager, the component invocation context manager comprising a stack for maintaining component invocation contexts;

determining, at a partition-aware container, that a target resource of a request is included in the collection of deployable resources of the targeted partition;

setting, at the partition-aware container, a component invocation context that is associated with the partition identifier of the targeted partition;

performing, by the partition-aware container performs, one of

registering the component invocation context that is associated with the partition identifier of the targeted partition by pushing the component invocation context that represents the request onto the stack, or

looking up a current component invocation context at the component invocation context manager by requesting the current component invocation context from the stack.

9. The method of claim 8, wherein registering the current component invocation context that is associated with the partition identifier of the targeted partition comprises:

receiving, at a front end component, the request including target information, the target information indicating the targeted partition; and

wherein pushing the component invocation context that is associated with the partition identifier of the targeted partition onto the stack includes making a call, by the partition-aware container, to an application programming interface of the component invocation context manager.

10. The method of claim 9, wherein the partition-aware container is configured to, after registering the component invocation context that is associated with the partition identifier of the targeted partition at the component invocation context manager, and upon completion of the request, unregister the component invocation context that is associated with the partition identifier of the targeted partition at the component invocation context manager, the unregistering comprising:

unregistering, by the partition-aware container via the application program interface, the component invocation context that is associated with the partition identifier of the targeted partition at the component invocation context manager.

11. The method of claim 8, further comprising:
