The POCOPRO C++ Frameworks are used by leading companies worldwide.

Remoting for C++

Web services, Microservices, REST APIs and Remote Methods/RPC for C++.

Web services, REST APIs and microservices have significantly changed the way complex software systems are designed, built and deployed. POCOPRO Remoting makes these technologies and concepts available to C++ developers.

Multi-Protocol Stack and Code Generator

Remoting for C++ is a web services and remote method call framework for C++. Remoting supports different communication protocols. This includes JSON-based REST APIs, JSON-RPC, SOAP and a highly efficient binary protocol.
Remote services are implemented as C++ classes, annotated with special comments. The Remoting code generator takes care of the rest. There is no need to maintain a separate interface definition using an interface definition language (IDL).

SOAP and WSDL/XSD-to-C++ Code Generation

Remoting also includes a tool for generating C++ code from WSDL 1.1 (document/literal wrapped) and XML Schema (XSD) documents. This makes it possible to build C++ clients for SOAP 1.1 and 1.2 web services built with Java, Microsoft .NET, or other middleware technologies.

Remoting Features

Cross-Platform & Interoperability

Easily communicate between different hardware and operating system platforms. Or clients and servers built in other programming languages and environments such as Java or .NET.

Multi Protocol Support

Remoting supports sockets, HTTP, REST, JSON-RPC and SOAP. Thanks to a flexible and modular design, other protocols can be added by implementing a new protocol library.

Code Generator

The RemoteGen code generator generates protocol independent, human-readable communication code from annotated C++ header files.

Extensive C++ Type Support

All standard C++ types and some STL collection types (including enumerations, std::string, std::vector, std::set and std::multiset), as well as user-defined classes and structures are supported as method arguments and return types.


Implement REST API endpoints in C++. Supporting different forms of parameter passing (path, query string, header, body, JSON) as well as authentication, CORS, etc. Or generate client code to call external REST APIs.


Implement microservices in C++ exposing REST APIs for best interoperability. Or use the super efficient binary transport protocol for communication between C++ applications.


Generate C++ client and server code for SOAP web services from WSDL documents. Implement SOAP 1.1/1.2 web services in C++ that can be called from Java and .NET WCF applications with support for MTOM, HTTPS, HTTP compression (gzip content encoding) and HTTP Basic and Digest authentication.

Remote Events

Support for events in remote interfaces enables implementation of server-pushed asynchronous notifications or publish-subscribe messaging patterns.


The following code snipped shows an example for how to define a RESTful API with Remoting. This definition is specific to the Remoting REST transport. Note how the method names correspond to HTTP methods. Also note the special comments. The Remoting code generator (RemoteGen) parses these definitions and generates C++ code that implements serialization, deserialization and remote invocation.

//@ serialize
struct User
    Poco::Optional<std::string> name;
    Poco::Optional<std::string> password;
    Poco::Optional<std::set<std::string>> permissions;
    Poco::Optional<std::set<std::string>> roles;

//@ remote
//@ path="/api/1.0/users"
class UserCollectionEndpoint
    User post(const User& user);
        /// Create a new user.

    //@ $maxResults={in=query, optional}
    //@ $start={in=query, optional}
    std::vector<User> get(int maxResults = 0, int start = 0);
        /// Return a list of user objects, starting with
        /// the given start index, and return at most
        /// maxResults items.

//@ remote
//@ path="/api/1.0/users/{name}"
class UserEndpoint
    //@ $name={in=path}
    User put(const std::string& name, const User& user);
        /// Update a user (calls patch()).

    //@ $name={in=path}
    User patch(const std::string& name, const User& user);
        /// Update a user.

    //@ $name={in=path}
    User get(const std::string& name);
        /// Retrieve a user by name.

    //@ $name={in=path}
    void delete_(const std::string& name);
        /// Delete a user.

Remote Method Sample

The following code snipped shows an example for a remote methods-based service that can use the efficient binary Remoting transport over sockets or HTTP, the JSON-RPC or the SOAP transport. Again, note the special comments. The Remoting code generator (RemoteGen) parses these definitions and generates C++ code that implements serialization, deserialization and remote invocation.

//@ serialize
struct User
    std::string name;
    Poco::Optional<std::string> password;
    Poco::Optional<std::set<std::string>> permissions;
    Poco::Optional<std::set<std::string>> roles;

//@ remote
class UserManager
    void addUser(const User& user);
        /// Create a new user.

    void updateUser(const User& user);
        /// Update a user.

    User getUser(const std::string& username);
        /// Retrieve a user by name.

    //@ $maxResults={optional}
    //@ $start={optional}
    std::vector<User> getUsers(int maxResults = 0; int start = 0);
        /// Return a list of user objects, starting with
        /// the given start index, and return at most
        /// maxResults items.

    void deleteUser(const std::string& username);
        /// Delete a user.

Open Service Platform

Dynamic C++ module system, nanoservices and application server.

Today's applications are becoming ever more complex. A large part of this complexity stems from the need to support different configurations, e.g. for different devices, operating system environments or customer needs. Huge monolithic applications like the ones developed in the past do not (or only at an enormous cost) provide the necessary flexibility required today.

Build, deploy and manage dynamic, modular C++ applications

Open Service Platform (OSP) enables the creation, deployment and management of dynamically extensible, modular applications, based on a powerful plug-in and (nano-) services model. Applications built with OSP can be extended, upgraded and managed even when deployed in the field. At the core of OSP lies a powerful software component (plug-in) and services model based on the concept of bundles. A bundle is a deployable entity, consisting of both executable code (shared libraries) and the required configuration, data and resource files.

Plug-in and service-based architecture

Bundles extend the functionality of an application by providing certain services. A central Service Registry allows bundles to discover the services provided by other bundles. Bundles can be installed, upgraded, started, stopped or removed from an application (programmatically, or using a web- or console based administration utility) without the need to terminate and restart the application.

Open Service Platform

Simplify large-scale C++ application development and deployment

This component-based architecture of OSP addresses an increasing problem in software development: The large number of application configurations that need to be developed and maintained. The standardized OSP component architecture simplifies this configuration and deployment process significantly.

Open Service Platform Features

Plug-In and Services Architecture

Create dynamically extensible C++ applications based on a powerful plug-in/component and services architecture. Combine executable code (shared libraries), configuration files and other resources like web pages or images in bundles - easily manageable deployment units.

Dynamic Deployment & Lifecycle Management

Install, start, stop, upgrade or uninstall an application's bundles dynamically, at run-time. Without the need to restart the entire application.

Dependency Management

Automatically manage version dependencies between bundles. OSP makes sure that all dependencies are satisfied and that bundles are started or stopped in correct order.

Service Registry

Provide and find services in an application through a central ServiceRegistry. Dynamically react to availability of services through events or ServiceListener objects.

Management Console & CLI

Manage an application's bundles through a built-in web-based Bundle Administration Utility or through an extensible console based shell (CLI) administration service.

Web Application Server

An integrated web application server enables powerful dynamic C++ web applications. Routing, sessions, authentication, access permissions and CSRF protection can be configured using metadata and are handled by the framework, without the need for extra code.

Signed Bundles

Bundles can be cryptographically signed. Make sure bundles installed in your system come from a known publisher and have not been tampered with.

Standard Services

Readily available services for user authentication and authorization (including LDAP integration), preferences and configuration data, extension points, database access, email, network environment change detection, web events, etc.
