# Creating and Updating JSF Libraries

To create or update a JSF Library, Windows -> Preferences -> Web and XML -> JSF Libraries
Initially your list of libraries may be empty unless there is a plugin-provided library present.

### New Library

To create a new JSF Library, select "New..." button.

On this dialog you must:

- provide a workspace unique name for the library
- using the "Add..." button choose one or more JAR files to be included in this library

Optionally you may:

- specify the JSF version that this collection of jars supports (At this time this is unused)
- mark this as an implementation using the "is JSF Implementation" checkbox

Click "Finish" button to create your new JSF Library

### Update JSF Library

There may be a need to update the jars associated with this library. This can occur if:

- you want to add or remove libraries, or,
- you need to update the location of a jar reference

To update the selected JSF Library, choose "Edit..."
There is currently no way to update a jar entry to locate a missing jar. You must first remove the missing jar and then add it back.
Changes will be saved after you click "Finish" button.
