You can add activities within the project after you have created a project. You can either create a new activity or edit an existing one. For example, let us suppose you are creating or editing an JMS Source activity.

Following are the steps to save this activity in a Project:

Click Configure > SOURCES > JMS Source.
Click CREATE JMS Source.
On Create JMS Source screen, provide the values in all the fields. For more information, click here.
Expand Advanced Properties.
Select the project from the Project drop-down list box.

By default, the Project drop-down list box displays the default project of the logged-in user as the selected project. If you do not add your activity in any of the listed projects then the activity will be added in the Default project of the logged-in user.
Click Save to save the JMS source activity.
Now, you can view the JMS source activity on the Projects page.
