Abstract:
A system has at least one requesting application residing upon a requesting application server, a cluster of processing message servers, a resource adapter in the form of executable code being executed by a processor on a first computer, the resource adapter to receive a request from the requesting application; transmit the request to the cluster of processing message servers; monitor processing of the request on the cluster of processing message servers; handling any exception in the processing of the request; and responding to the requesting application when the processing is complete. The system also includes an interposed transaction manager in the form of executable code being executed by a processor, the interposed transaction manager to receive transactional operations associated with the requests, and providing transaction guarantees related to the transactional operations.
Abstract:
A system and method can provide a scalable data storage in a middleware environment. The system can include a cluster of replicated store daemon processes in a plurality of processing nodes, wherein each machine node can host a replicated store daemon process of the cluster of replicated store daemon processes. Additionally, the system can include one or more replicated stores associated with an application server the processing node. The replicated store daemon cluster can persist data from a replicated store to another node, the other node also being associated with the replicated store daemon cluster. The system and method can additionally support a messaging service in a middleware environment. The messaging service can use the replicated store to store a copy of a message in the local processing node and on another processing node associated with the same replicated store daemon cluster.
Abstract:
In accordance with an embodiment, a system and method provides a messaging service in a multitenant application server environment. Deployable resources are usable within the multitenant application server environment and groupings of resources are defined by resource group templates within a domain. One or more partitions are provided, with each partition providing an administrative and runtime subdivision of the domain that can be associated with a tenant. Java message service (JMS) resources are defined within a resource group template or a resource group, and instantiated within a partition to enable messaging for applications deployed within the partition and between partitions. Integrating JMS in a multitenant application server environment further includes a foreign JMS server feature which maps remotely hosted JMS connection factories and JMS destinations into a local partition's JNDI, so that bridges and applications in turn gain access to these resources by looking them up in this name-space.
Abstract:
A computer-controlled method of handling proprietary features in a messaging system includes receiving an object from a requesting application, determining that the object invokes proprietary features of a messaging system, accessing a wrapper library and wrapping the object in an appropriate wrapper for the messaging system to produce a wrapped object, the wrapper to preserve the proprietary feature, and transmitting the wrapped object to the messaging system.
Abstract:
In accordance with an embodiment, described herein is a system and method for supporting object-based security features for use with messaging services in an application server environment. Credentials can be associated with a JNDI initial context or a JMS connection instead of a thread. For JNDI operations, a lookup call from the initial context can use a security subject in an initial context regardless of a security subject attached to a current thread of the lookup call. For JMS operations, the object-based security model can be enabled on a JMS connection factory, which is used to create a JMS connection associated a security subject based on credentials supplied to create the JMS connection. The JMS connection performs a plurality of JMS operations on different threads using the security subject. The object-based security model is automatically enabled for JMS connection operations once the JMS is accessed using an OBS-enabled JNDI context.

Abstract:
In accordance with an embodiment, a system and method provides a messaging service implementing a unit-of-order guarantee in a multitenant application server environment. The system and method of implementing unit-of-order utilizes an improved path service for routing all messages having a particular unit-of-order to the same member of the cluster. The improved path service allows for scalability of the cluster and reduced resource utilization, thereby improving the performance of a clustered computing system providing the messaging service.
Abstract:
In accordance with an embodiment, a system and method provides a messaging service in a multitenant application server environment that includes a domain configuration defining an application server domain for execution of the software applications, and one or more partitions of the domain. Each partition is associated with a partition configuration and provides a subdivision of the domain. One or more resource groups enable partition-specific information for one or more deployable resources. Java message service (JMS) resources are defined within a resource group, and instantiated within a partition to enable messaging for applications deployed within the partition and between partitions. A custom store is defined within each of the resource groups for use by the JMS resources. Components of the custom store are fully partition scoped.
