Traditionally, web-based applications and services have relied on non-standard interfaces to participate as first-class citizens in the DDS Global Data Space. RTI® Web Integration Service leverages the Web-Enabled DDS OMG standard to provide a simple generic standards-based interface that provides a transparent bridge between web-based services and unmodified DDS applications.
Simply set up Web Integration Service to create DDS entities associated with web-based client applications. No changes are required in the RTI Connext® DDS applications.
Key benefits of Web Integration Service:
Reduces the time and effort spent integrating web-based protocols with Connext DDS applications, providing a standards-based generic out-of-the-box solution.
Supports disconnected or stateless clients that would otherwise need to join a domain, discover remote entities, and ensure that subscribers receive the information they sent.
Enables interoperability between applications written in different programming languages and operating systems.
Provides access control mechanisms to ensure that only authorized applications can access the DDS Global Data Space.

1.2. Paths Mentioned in Documentation
This documentation refers to:
<NDDSHOME>This refers to the installation directory for Connext DDS. The default installation paths are:
Linux® systems, non-root user:
/home/your user name/rti_connext_dds-version
Linux systems, root user:
Windows® systems, user without Administrator privileges:
<your home directory>\rti_connext_dds-version
Windows systems, user with Administrator privileges:
You may also see
%NDDSHOME%, which refers to an environment variable set to the installation path.
Whenever you see
<NDDSHOME>used in a path, replace it with your installation path.
Note for Windows Users: When using a command prompt to enter a command that includes the path
C:\Program Files(or any directory name that has a space), enclose the path in quotation marks. For example:
Or if you have defined the
<path to examples>By default, examples are copied into your home directory the first time you run RTI Launcher or any script in
<NDDSHOME>/bin. This document refers to the location of the copied examples as
<path to examples>.
Wherever you see
<path to examples>, replace it with the appropriate path. Default path to the examples:
/Users/your user name/rti_workspace/version/examples
/home/your user name/rti_workspace/version/examples
your Windows documents folder\rti_workspace\version\examples. Where
'your Windows documents folder'depends on your version of Windows. For example, on Windows 10 systems, the folder is
