An application processing method and apparatus, a storage medium, and a computer device are provided. The method includes: displaying a first child application page of a first child application; and acquiring, by using the first child application, a second child application identifier corresponding to a second child application to be jumped to. The first child application is run by a parent application. The method also includes: the parent application running the second child application when a jump is made from the first child application to the second child application; transferring page data corresponding to the second child application identifier to the second child application; and generating, according to the page data, a second child application page over the first child application page, and displaying the second child application page.

Techniques are disclosed for providing an application programming interface (API) as a service. In embodiments, a client provides code to be executed along with a configuration file for that code. Based on that, virtual machine(s) and load balancer(s) may be selected, a domain name service configured, and throttling and scaling configured. Through this, an API as a service may be provided on behalf of a client with minimal configuration required by the client or an administrator of a web service platform that provides the API as a service.

A computer architecture providing enhanced JVM security and a method of providing enhanced security for a JVM are disclosed. The host computer runs a single, first, trusted JAVA API library above which is located a hypervisor software layer, and then at least one untrusted JAVA API library. The code of each second, upper, untrusted JAVA API library is modified at, or before runtime to call the hypervisor software layer instead of the JVM to thereby create a silo corresponding to each of the second, upper, untrusted JAVA API libraries. Each silo extends between the host computer and the corresponding second, upper, untrusted JAVA API library. The hypervisor software layer is operated to only permit communication between each of the second, upper, untrusted JAVA API libraries and a corresponding portion of the memory and functional assets of the host computer. Consequently, each of the second, upper, untrusted JAVA API libraries cannot communicate with all of the host computer memory and/or all of the host computer functional assets. A computer program product is also disclosed.

An Internet of things (IoT) controller may execute a first IoT application, associated with operating an IoT device, and a second IoT application associated with operating the IoT device. The IoT controller may load an IoT application program interface (API) associated with the first IoT application and the second IoT application, and may identify a first set of functions including a first function, associated with the first IoT application, and a second function associated with the second IoT application. The IoT controller may translate, based on the IoT API, the first set of functions to a second set of functions including a third function, associated with the first IoT application, and a fourth function associated with the second IoT application. The IoT controller may cause the IoT device to operate, based on the second set of functions, during the execution of the first IoT application and the second IoT application.

The invention relates to blockchain technologies such as the Bitcoin blockchain. The invention uses a novel technique to decompose the functionality of a blockchain transaction script into several chunks or functional parts, and to use the output of a chunk as the input of the next chunk. Advantageously, this allows the blockchain to be used for ever complex tasks and computations while minimising script size, and also provides a novel architecture for the distributed execution of computational processes. The invention comprises a method of using a plurality of blockchain transactions to execute a computer implemented task, the method comprising the steps: using an unlocking script (ULS1) in a blockchain transaction (Tx2) to present at least one data item to a locking script (LS1) of another transaction (Tx1) so as to provide a result on a stack; generating a further unlocking script (ULS2) which comprises the result provided on the stack; presenting the further unlocking script (ULS2) to a further locking script (LS2) such that the result from the stack is provided as input to the further locking script.

Body lumen occlusion apparatus and methods are described.

A method for a java application to access an intelligent key apparatus. The apparatus comprises: a java application calling a JNI interface; obtaining a corresponding lower level interface function according to a correspondence table of a JNI interface function and the lower level interface function; converting a source parameter list of the JNI interface function into a target parameter list of the corresponding lower level interface function according to the target parameter list of the lower level interface function; calling a lower level interface; accessing an intelligent key apparatus; obtaining a returned result; and returning a value of the returned result to the java application. By means of the method in the present invention, it is not easy to obtain a source code by decompiling a java application, thereby improving the security of the java application accessing an intelligent key apparatus.

In one implementation, systems and methods are provided for developing a computer-implemented digital experience application having a first and a second micro-application. Each micro-application includes a front end interface configured to receive and display information. The first micro-application includes a first event manager configured to detect an application event belonging to a category, and a first state manager configured to detect an application state belonging to the category. The digital experience application further includes a driver application configured to host the first and second micro-applications, an event hub configured to receive the detected application event from the first micro-application, and a state store configured to store the detected application state received from the first micro-application. The second micro-application includes a second event manager configured to receive the detected application event from the event hub, and a second state manager configured to receive the detected application state from the state store.

Methods and systems for program code conversion for cross-platform compatibility are disclosed. A plurality of original function calls are identified in an original program. The original program is targeted to a first platform, and the original function calls comprise invocations of a plurality of functions implemented on the first platform. It is determined whether individual ones of the original function calls correspond to alternative function calls in an index. For the original function calls that correspond to the alternative function calls in the index, the original function calls are replaced with corresponding alternative function calls in a modified program. The modified program is targeted to a second platform, and the alternative function calls comprise invocations of a plurality of functions implemented on the second platform.

The electronic device may invoke a host application. The device may display a first host user interface on the display, the first host user interface including a first host user interface component associated with a child application. In response, the device may invoke, using the host application, the child application executed at the electronic device. The device may transmit, using the host application, a request for data associated with a child user interface component to the child application. The device may transmit, using the child application, the request for data associated with the child user interface component to a child application server, wherein the data associated with the child user interface component is inaccessible by the host application. The device may receive, using the child application, the data associated with the child user interface component from the child application server. The device may display the child user interface component.
