Deploy Import API applications

The Application Deployment System (ADS) provides the functionality used to deploy your custom Import API applications. It automatically deploys a subset of the .NET assemblies files used by an application, such as OAuth2, logging, and telemetry. At this time, you do need to manually post specific assemblies but enhancements to this process are planned for future releases.

Note: While you can implement a variety of custom import utilities, the Import API doesn't support calls made to it from within event handlers.

General deployment guidelines

Verify that your application follows these general guidelines before deploying it to Relativity:

• Verify that the NuGet package for the Relativity.DataExchange.Client.SDK is installed in your Visual Studio project. See Get started with the Import API.

The NuGet package installation lists all the required dependencies for this SDK as shown in the following screenshot:

• Verify that you can export your application from your development environment as a RAP file for deployment in production environments. By building your custom application through the Application Deployment System (ADS), you can ensure all the dependencies, including the Import API SDK with all required dlls, are included in the RAP file. See Build applications and Step 10 - Finalize and export application.

Required .NET assemblies and binaries

The following table lists the .NET assemblies and binaries that are required for a custom Import API application based on how it is deployed to Relativity.

*Indicates that you are deploying a custom application through an agent or a custom page built on the ADS framework.

**Indicates that you are deploying a custom application built outside of ADS, such as a console or desktop application, web service, or other implementation.

Additional information about .NET assemblies and binaries

Review the following sections for additional information about how to ensure that your specific type of custom application includes the required .NET assemblies and binaries.

Custom pages

When you deploy your custom application through a custom page, your .NET project should reference the SDK package, which ensures all required assemblies and native binaries are copied to the target folder. Use the information in the following sections to verify that your custom page includes all the required .NET assemblies and binaries.

To locate the required assemblies, compile your Visual Studio project. Navigate to <OutPath> for your .NET project. For example, if you compile a release build, these files are located in this path:

1
<Path to .NET custom page project>\<OutPath>

Next, verify the .NET assemblies and native binaries as described in the following sections are in your custom page project.

Agents

When you deploy your custom application through an agent, you need to add the required assemblies listed in the following sections as resource files. For more information, see Resource files on the Relativity Documentation site.

.NET applications

For custom .NET applications using the Import API, you need to add the required assemblies listed in the following sections as resource files. For more information, see Resource files on the Relativity Documentation site.

Relativity.DataExchange.Client.SDK .NET assemblies

For a custom page or .NET application, the target folder must contain Relativity.DataExchange.Client.SDK .NET assemblies. Verify that these files exist in this folder. If necessary, add them to the folder.

For an agent, add the following assemblies as resource files to Relativity. See Resource files on the Relativity Documentation site.

• FreeImage.dll (native binary) - not required for agents.
• FreeImageNET.dll - not required for agents.
• Relativity.DataExchange.Client.SDK.dll
• Relativity.DataTransfer.MessageService.dll - not required for the Relativity.DataExchange.Client.SDK v1.7.6 and above.

Relativity.Transfer.Client .NET assemblies

For a custom page or .NET application, the target folder must contain Relativity.Transfer.Client .NET assemblies. Verify that these files exist in this folder. If necessary, add them to the folder.

For an agent, add the following assemblies as resource files to Relativity. See Resource files on the Relativity Documentation site.

• Relativity.Transfer.Client.Aspera.dll
• Relativity.Transfer.Client.Core.dll
• Relativity.Transfer.Client.dll
• Relativity.Transfer.Client.FileShare.dll
• Relativity.Transfer.Client.Http.dll
• Renci.SshNet.dll
• Polly.dll
• FaspManager.dll

Outside In binaries

For a custom page or .NET application, the target folder must contain the Outside In binaries in the oi subfolder. Verify that these files exist in this folder. If necessary, add them to the folder. You may need to add configuration information for the OI libraries to your project's .csproj setup file

Note: Make sure that the version for the oi.dll matches the version of the other native binary files for Outside In. In other words, all the Outside In binaries in your custom application must be the same version. Don't mix the versions of the file identification assembly and the other binaries. Inconsistent versions may cause file identification issues.

• oi.dll
• .\oi\cmmap000.bin
• .\oi\oilink.exe
• .\oi\oilink.jar
• .\oi\sccca-R1.dll
• .\oi\sccch-R1.dll
• .\oi\sccda-R1.dll
• .\oi\sccex-R1.dll
• .\oi\sccfa-R1.dll
• .\oi\sccfi-R1.dll
• .\oi\sccfmt-R1.dll
• .\oi\sccfnt-R1.dll
• .\oi\sccfut-R1.dll
• .\oi\sccind-R1.dll
• .\oi\scclo-R1.dll
• .\oi\sccut-R1.dll
• .\oi\wvcore-R1.dll

You should have entries like the following examples in your .csproj file (these entries may be located in different <ItemGroup> sections)
