    摘要： A method for pre-verification of a code module when the code module is installed or updated in a virtual machine, comprising: loading codes in the installed or updated code module; performing code verification on the codes in the code module; if the code verification is passed, generating a certificate of the code module; and storing the code module passing the code verification and its certificate. The present invention also discloses a method for verification of a code module at runtime of the code module in a virtual machine, comprising loading codes in the code module; generating a certificate of the code module based on the loaded codes; if the generated certificate of the code module and a pre-stored certificate of the code module are identical, verifying the code module to be valid; otherwise performing a pre-verification on the code module.

    摘要： A data processing system corrects handprinted character input represented as a sequence of points described by a writing path of a pointing device. The system receives a writing path signal from a pointing device in the data processing system, describing a first hand printed character input. The system performs character recognition on the writing path signal to provide a first character string. The system then displays the first character string in an edit pad area. The system then receives a correcting writing path signal in the edit pad area from the pointing device, describing a correction to the first hand printed character input. The system then performs character recognition on the correcting writing path signal to provide a second character string.

    摘要： Broadcast information is classified in categories to facilitate user selection and filtration of the broadcast information which is processed for presentation to the user. The broadcast information is transmitted in the form of a meta frame and one or more category frames which are repeated in a continuous cycle. Meta frames and category frames are distinguished and identified by major and minor codes following a frame starting delimiter. The meta frame contains a description of each of the available categories, together with an identification of respective category major and minor codes, the frequency on which the respective category frame is transmitted if multiple frequencies are employed, and the relative position of the respective category frame within transmission cycle. If multiple frequencies are employed, the meta frame may be repeatedly broadcast on a base frequency while subsets of the category frames are transmitted on different frequencies, or the meta and category frames may be repeated in sequence on all frequencies but with varying offsets. Upon user selection of a category, the category information within the meta frame is employed to construct or key a filter for the broadcast information. The selected category frame data is received and added to a local database, formatted, and presented to the user.

    摘要： Innovative managers of persistent data are provided. As an example, in a client/server environment, a persistent manager object may be initialized on both the client and server subsystems. The persistent manager objects may be instances of the same persistent manager class. The persistent manager object on the client subsystem may receive a request to store persistent data and the persistent manager object on the client sends the request to the persistent manager object on the server subsystem. The persistent manager object on the server subsystem may then store the persistent data to make it subsequently be available for the client subsystem.

    摘要： A system and method are provided to allow demand loading and discarding of Java executable image (JXE) files. The virtual machine allocates an address space for a requested JXE program. The read-only portion of the JXE file is memory mapped from its nonvolatile location to the allocated memory space using read-only mapping and the read/write section of the JXE file are loaded into memory. When a page of the JXE program is needed, a page fault occurs if the read-only portion has not been loaded into memory. The operating system's page fault handler retrieves the needed page(s) from the nonvolatile storage location based upon the mapping data that resulted from the previously performed memory mapping. Because the read-only section of the JXE file is memory mapped using read-only mapping, the operating system's paging process is free to discard previously loaded memory pages that contain read-only portions of the JXE file.

    摘要翻译： 提供了一种系统和方法来允许需求加载和丢弃Java可执行映像（JXE）文件。 虚拟机为所请求的JXE程序分配一个地址空间。 使用只读映射将JXE文件的只读部分从其非易失性位置映射到分配的存储空间，并将JXE文件的读/写部分加载到内存中。 当需要JXE程序的页面时，如果只读部分尚未加载到内存中，则会发生页面错误。 操作系统的页面错误处理器基于从先前执行的存储器映射产生的映射数据，从非易失性存储位置检索所需的页面。 由于JXE文件的只读部分是使用只读映射进行内存映射，因此操作系统的分页过程可以放弃先前加载的包含JXE文件只读部分的内存页面。
