    • Middleware application for managing communication between a client and a web service so that changes in the web service information, such as a change in the web service location, are addressed by the middleware application is disclosed. A developer registers web services in a repository. The middleware application generates a web service proxy based on web service information entered in the repository, and generates a new web service proxy when the web service information changes. The developer can then write code for client applications without the need to change code when changes are made in the web service information. Responsive to a client request, the middleware application accesses the repository to match the request with a web service. The middleware application transmits the request through the web service proxy to the web service. The method for using the middleware application comprises entering web service information in a repository, generating a web service proxy for a web service registered in the repository, and storing the web service proxy, so that changes in web service information, such as the web service location, will cause a new web service proxy to be generated.
    • 公开了用于管理客户端和web服务之间的通信的中间件应用程序,以便web服务信息的改变,诸如web服务位置的改变,被中间件应用程序所解决。 开发者在存储库中注册Web服务。 中间件应用程序基于在存储库中输入的Web服务信息生成Web服务代理,并在Web服务信息更改时生成新的Web服务代理。 然后,开发人员可以为客户端应用程序编写代码,而无需在Web服务信息中进行更改时更改代码。 响应于客户端请求,中间件应用程序访问存储库以将请求与Web服务相匹配。 中间件应用程序通过Web服务代理将请求发送到Web服务。 使用中间件应用程序的方法包括在存储库中输入Web服务信息,为存储库中注册的Web服务生成Web服务代理,并存储Web服务代理,以便Web服务信息(如Web服务) 位置,将导致生成新的Web服务代理。

    • A method, system, and computer program product for improving the performance of distributed object systems. A remote object is replicated to the node of the distributed system from which it is accessed. The scope of the replication is a transaction. Thereafter, method invocations on the object occur locally, avoiding the performance overhead of frequent round trips to the remote persistent object store. Changes made to a replicated object by a transaction are represented using a tree structure that is internally managed by the application. When an application or application user has made modifications to a replicated object and requests to commit the modifications, a determination is first made as to whether committing the modifications will result in an unacceptable data conflict. If no unacceptable data conflict will occur, and after resolution of those conflicts that can be resolved, the modifications are committed. Nested transactions are supported, where each child transaction may commit or roll back independently.
    • 一种用于提高分布式对象系统性能的方法,系统和计算机程序产品。 远程对象被复制到被访问的分布式系统的节点。 复制的范围是一个事务。 此后,对象上的方法调用本地发生,避免了对远程持久对象存储的频繁往返的性能开销。 使用由应用程序内部管理的树结构来表示由事务对复制对象所做的更改。 当应用程序或应用程序用户对复制对象进行修改并请求提交修改时,首先确定提交修改是否会导致不可接受的数据冲突。 如果不会发生不可接受的数据冲突,并且在解决可以解决的冲突之后,修改将被提交。 支持嵌套事务,每个子事务可以独立提交或回滚。

    • A technique for providing a transaction management subsystem for an enterprise computing environment in which multiple concurrent and/or nested transactions may access the same Enterprise JavaBeans (EJBs) simultaneously. The transaction management subsystem provides a view for each transaction which includes an independent version of an EJB's business logic and its instance data. When an application or application user has made modifications to an EJB version and requests to commit the modifications, a determination is first made as to whether committing the modifications will result in an unacceptable data conflict with other versions of the same EJB. If no unacceptable data conflict will occur, and after resolution of those conflicts that can be resolved, the modifications are committed. The management subsystem also supports nested transactions, where each subtransaction may have an independent view of an EJB. Subtransactions may commit or roll back independently. Changes made by a transaction are represented using a tree structure that is internally managed by the application.
    • 一种用于为企业计算环境提供事务管理子系统的技术,其中多个并发和/或嵌套事务可以同时访问同一企业JavaBeans(EJB)。 事务管理子系统为包含EJB业务逻辑及其实例数据的独立版本的每个事务提供一个视图。 当应用程序或应用程序用户对EJB版本进行修改并请求提交修改时,首先确定提交修改是否会导致不可接受的数据与同一EJB的其他版本冲突。 如果不会发生不可接受的数据冲突,并且在解决可以解决的冲突之后,修改将被提交。 管理子系统还支持嵌套事务,每个子事务可以具有EJB的独立视图。 子交易可以独立提交或回滚。 使用由应用程序内部管理的树结构来表示事务所做的更改。
