Running Multiple Custom Domains on GlassFish Server

Let’s see how to easily set up a few domain names for Java application hosted with GlassFish container servlet, which combines enterprise-class facilities and open-source cost efficiency. It’s an enterprise-ready application server with true interoperability and a wide range of features including superior documentation, configuration and administration.

To run multiple domains for your Java site on GlassFish server just follow the next simple steps.

1. Log into the platform dashboard and click Create environment button.

2. Pick GlassFish as an application server and specify the cloudlet limits for it. Then type your environment name and click Create button.

4. After that you need to add a CNAME record or set an A Record, as it is described in Custom Domains document.

5. For binding your custom domain names click the Settings button next to your environment and choose the Custom domains setting. Then enter your domains in the appropriate field (we will use and as examples) and click Bind button.

Note: We’ve put entries into our hosts file for local testing so this will work only from our machine, which has those hosts' entries.

6. When you created the environment, the platform sent you the link and credentials to GlassFish DAS node. Log in to the admin panel using these credentials and navigate to the Applications tab in order to deploy your application.
