Abstract

A virtual application packaged for a specific executing environment may be executed on a processing device having an executing environment different from the specific executing environment. A reference, included in extracted installer metadata, to one or more key paths of a hierarchically-structured data store may be modified according to a set of rules related to the executing environment detected in the processing device. The modified extracted installer metadata may be provided to an installer for installing the virtual application. During execution of the virtual application, a request to read, write, or modify the hierarchically-structured data store may be intercepted and changed, such that a first key path included in the request may be mapped to a second key path, based on the detected executing environment. Similarly, a response to the request, which may include the second key path, may be intercepted and modified, to the first key path.

Dependent claims

A machine-implemented method for executing a virtual application on a processing device having a first executing environment different from a second executing environment for which the virtual application was packaged, the machine-implemented method comprising:

extracting, on the processing device, installer metadata associated with the virtual application, the installer metadata including information with respect to at least one first key path of a hierarchically-structured data store;
automatically modifying, by the processing device, one or more of the at least one first key path included in the extracted installer metadata to one or more of at least one corresponding second key path of the hierarchically-structured data store based on the first executing environment on the processing device;
providing the modified extracted installer metadata to an installer;
intercepting, by the processing device during execution of the virtual application, a request including a reference to one of the at least one first key path;
automatically modifying, by the processing device, the one of the at least one first key path referenced in the intercepted request to a corresponding one of the at least one second key path based on the first executing environment;
and
releasing the intercepted request referencing the corresponding one of the at least one second key path for further processing.

A processing device configured to execute a virtual application packaged to execute in a first executing environment which is different from an executing environment of the processing device, the processing device comprising:

a first interceptor configured to automatically intercept a request from the virtual application to read, write, or modify a first portion of a hierarchically-structured data store and to modify the request to produce a modified request to read, write, or modify a second portion of the hierarchically-structured data store, instead of the first portion, before the request is processed, the request being modified by changing a first key path of the hierarchically-structured data store, referenced in the request, to a second key path of the hierarchically-structured data store based on a set of executing environment rules that matches the executing environment of the processing device and maps the first key path to the second key path;
and
a second interceptor configured to automatically intercept a response to the modified request to read, write, or modify the second portion of the hierarchically-structured data store and to modify the response to produce a modified response to the request of the virtual application to read, write or modify the first portion of the hierarchically-structured data store, before the modified response is delivered to the virtual application, the response being modified by changing the second key path referenced in the response to the first key path based on the set of executing environment rules that matches the executing environment of the processing device.

At least one item selected from a group of items consisting of a random access memory, a read only memory, a disk, and an optical disk, the at least one item having instructions recorded thereon for a processor to perform a method comprising:

detecting an executing environment of a processing device;
determining a mapping from a first key path referenced by a virtual application packaged for execution in a second executing environment to a second key path based on the detected executing environment;
automatically modifying a request from the virtual application for accessing a first portion of a hierarchically-structured data store defined by the first key path of the hierarchically-structured data store referenced in the request to a modified request for accessing a second portion of the hierarchically-structured data store defined by the second key path of the hierarchically-structured data store referenced in the automatically modified request based on the determined mapping;
processing the modified request for accessing the second portion of the hierarchically-structured data store defined by the second key path;
and
automatically modifying a response to the modified request to be a response to the request from the virtual application for accessing the first portion of the hierarchically-structured data store, the automatically modifying the response including modifying the second key path referenced in the response to the first key path referenced in the automatically modified response based on the determined mapping;
and
providing the modified response to the virtual application.
