The following image shows the architecture of the User Libraries repository.
To download and install some specific third-party Java libraries or database
drivers that are needed by Talend Studio, you need to connect to the User Libraries
repository (integrated within the Nexus artifact repository) and its embedded repository
When Talend Studio opens, the
external libraries missing from the local
repository are detected. You are prompted to download them from the remote Nexus
repository, hosted by Talend,
and install them.
Talend Administration Center is connected to Talend Studio and to the local repository and the installed libraries are shared automatically.
For more information on how to install external libraries, see Installing external modules.
