# EJB Module Deployment Assistant --> Step 1 - Select Archive

Tasks Related Topics

## Overview

The EJB Module Deployment Assistant helps you deploy a new EJB to one or more servers in the domain. You can select either an archived EJB module (`.jar` file), or an EJB in exploded `.jar` format.

Use the links in the Location field to browse directories on the Administration Server machine and locate the EJB to deploy. If the EJB does not reside on the Administration Server machine, first use the upload link to upload the EJB `.jar` file. This places the archive in the Administration Server's configured upload directory, and automatically opens that directory in the Location field.

When the assistant detects an `.jar` file or exploded `.jar` directory in the current directory, it lists the archive or directory name as a selection beneath the Location field. Select the name of the archive or directory you want to deploy.

If your domain contains multiple WebLogic Server instances, click Target Module to deploy the EJB to a single server, or to multiple server instances or clusters.

In a single server domain, click Continue to automatically target the EJB to the available server instance.
