Abstract

In accordance with an embodiment, described herein is a system and method for supporting the use of connectors in an application server environment. The method can provide, a plurality of deployable resources which can be used within the application server environment, and one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain. The methods and systems can associate one or more deployed partition-level resource adapters to the one or more partitions, each of the one or more deployed partition-level resource adapters associated with one of the one or more partitions. Finally, the methods and systems can determine, by a connector container, a partition scope of one of the one or more deployed partition-level resource adapters.

Claims

1. A system for supporting use of connectors in a multitenant application server environment, comprising:

one or more computers, including an application server that enables deployment and execution of software applications, wherein the application server is associated with a domain configuration that is used at runtime to define a domain for execution of the software applications, and a plurality of partitions,

wherein each of the plurality of partitions is associated with a partition configuration, and wherein each partition provides a subdivision of the domain and includes one or more resource groups of a plurality of resource groups, wherein the one or more resource groups are defined by one or more resource group templates;

one or more deployed partition-level resource adapters, each of the one or more deployed partition-level resource adapters being deployed in a resource group of a partition of the plurality of partitions;

a connector container, wherein the connector container determines a partition scope of the one or more deployed partition-level resource adapters, wherein the partition scope is used to identify a partition identification (partition ID), based on a component invocation context, of a partition of the plurality of partitions within which a partition-level resource adapter is deployed; and

a partition classloader, the partition classloader deploying the one or more deployed partition-level resource adapters, the one or more deployed partition-level resource adapters being an instantiated version of a deployable resource adapter;

wherein, based upon the identified partition ID of partition of the plurality of partitions within which the partition-level resource adapter is deployed, access to the partition-level resource adapter is restricted to applications and resources within the partition associated with the identified partition ID.

2. The system of claim 1, wherein each of the one or more deployed partition-level resource adapters is scoped to their respective partition.

3. The system of claim 2, wherein access to each of the one or more deployed partition-level resource adapters is restricted to their respective partition.

4. The system of claim 1, wherein each of the one or more deployed partition-level resource adapters is scoped to their respective partition.

5. The system of claim 4, wherein access to each of the one or more deployed resource adapters is restricted to their respective partition.

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

7. The system of claim 1, further comprising a domain-level resource group, the domain level resource group comprising a domain-level resource adapter.

8. The system of claim 7, wherein access to the domain-level resource adapter is restricted to applications within the domain.

9. A method for supporting use of connectors in a multitenant application server environment, comprising:

providing, at one or more computers, including an application server that enables deployment and execution of software applications, wherein the application server is associated with a domain configuration that is used at runtime to define a domain for execution of the software applications, a plurality of partitions,

wherein each of the plurality of partitions is associated with a partition configuration, and wherein each partition provides a subdivision of the domain and includes one or more resource groups of a plurality of resource groups, wherein the one or more resource groups are defined by one or more resource group templates;

deploying, by a partition classloader, one or more deployed partition-level resource adapters, each of the one or more deployed partition-level resource adapters being deployed in a resource group at a partition of the plurality of partitions, the one or more deployed partition-level resource adapters being an instantiated version of a deployable resource adapter; and

determining, by a connector container, a partition scope of the one or more deployed partition-level resource adapters, wherein the partition scope is used to identify a partition identification (partition ID), based on a component invocation context, of a partition of the plurality of partitions within which a partition-level resource adapter is deployed;

wherein, based upon the identified partition ID of the partition of the plurality of partitions within which the partition-level resource adapter is deployed, access to the partition-level resource adapter is restricted to applications and resources within the partition associated with the identified partition ID.

10. The method of claim 9, wherein each of the one or more deployed partition-level resource adapters is scoped to their respective partition.

11. The method of claim 10, wherein access to each of the one or more deployed partition-level resource adapters is restricted to their respective partition.

12. The method of claim 9, wherein each of the one or more deployed partition-level resource adapters is scoped to their respective partition.

13. The method of claim 12, wherein access to each of the one or more deployed resource adapters is restricted to their respective partition.

14. The method of claim 9, further comprising:

providing a domain-level resource group, the domain level resource group comprising a domain-level resource adapter.

15. The method of claim 14, wherein access to the domain-level resource adapter is restricted to applications within the domain.

16. A non-transitory computer readable storage medium, including instructions stored thereon for supporting use of connectors in a multitenant application server environment which when read and executed by one or more computers cause the one or more computers to perform steps comprising:

providing, at the one or more computers, including an application server that enables deployment and execution of software applications, wherein the application server is associated with a domain configuration that is used at runtime to define a domain for execution of the software applications, a plurality of partitions,

wherein each of the plurality of partitions is associated with a partition configuration, and wherein each partition provides a subdivision of the domain and includes one or more resource groups of a plurality of resource groups, wherein the one or more resource groups are defined by one or more resource group templates;

deploying, by a partition classloader, one or more deployed partition-level resource adapters, each of the one or more deployed partition-level resource adapters being deployed in a resource group at a partition of the plurality of partitions, the one or more deployed partition-level resource adapters being an instantiated version of a deployable resource adapter; and

determining, by a connector container, a partition scope of the one or more deployed partition-level resource adapters, wherein the partition scope is used to identify a partition identification (partition ID), based on a component invocation context, of a partition of the plurality of partitions within which a partition-level resource adapter is deployed;

wherein, based upon the identified partition ID of the partition of the plurality of partitions within which the partition-level resource adapter is deployed, access to the partition-level resource adapter is restricted to applications and resources within the partition associated with the identified partition ID.
