摘要： Methods, systems, and articles of manufacture consistent with the present invention limit access to parts of a shared software library by using a class loader that generates a selective interface between an external process and a program file (such as a class definition) in the shared library. This prevents external processes from loading parts of the shared library that were meant to remain private or internal to the library. Methods, systems, and articles of manufacture consistent with the present invention load a program file, such as a class definition, from the shared library and generate an interface (such as an object) to the loaded program file. A determination of whether the program file can be exported is performed based upon a status indicator associated with the interface. The interface limits access to the program file if it is determined that the program file cannot be exported.

摘要： A method and apparatus for operating a local server computer of a client-server network includes a technique to receive a request from a client computer of the client-server network. A determination is made whether the request requires dynamically generated information from a servlet object of the client-server network. If so, a specified servlet object corresponding to the request may be uploaded from a remote server computer of the client-server network. The specified servlet object is then executed to obtain dynamically generated information corresponding to the request.

摘要： In a computer system having a data processing unit, memory, and a multitasking operating system that supports multiple threads of execution in a shared address space, a resource allocation subsystem includes an initialization procedure for initializing monitors, a notify procedure and a wait procedure. Each monitor has an associated event data structure denoting the status of the monitor as Signaled or Unsignaled. Each monitor also stores a waiters value indicating how many threads are waiting on the monitor, a tickets value indicating how many of the threads are to receive notifications, and an epoch counter value. The notify procedure updates any specified monitor to the Signaled status, updates the specified monitor's tickets value to indicate how many waiting threads are to receive notifications, and updates the epoch counter to indicate an epoch value associated with the updating of the specified monitor's status to Signaled. The wait procedure blocks execution of a calling thread until a specified monitor's status is updated to Signaled and the monitor's epoch information indicates an epoch value distinct from the epoch value when the calling thread called the wait procedure. The wait procedure unblocks the calling thread when monitor's tickets value is non-zero, and decrements the tickets value to indicate that the calling thread has consumed one ticket.

摘要翻译： 在具有数据处理单元，存储器和支持在共享地址空间中的多个执行线程的多任务操作系统的计算机系统中，资源分配子系统包括用于初始化监视器的初始化过程，通知过程和等待过程。 每个监视器都有一个关联的事件数据结构，将监视器的状态表示为“信号”或“无信号”。 每个监视器还存储指示监视器上等待多少个线程的服务器值，指示有多少线程要接收通知的票值以及时期计数器值。 通知程序将任何指定的监视器更新为信号状态，更新指定的监视器票据值，以指示接收通知的等待线程数量，并更新历元计数器，以指示与指定监视器状态的更新相关联的时期值到信号 。 等待程序阻止调用线程的执行，直到指定的监视器的状态更新为Signaled，并且当调用线程调用wait过程时，监视器的历元信息指示与epoch值不同的时期值。 当监视器的门票值不为零时，等待程序将取消阻塞调用线程，并减少票值值以指示调用线程已消耗一张票。
