Those libraries or database drivers, known as external modules, may be required by some of Talend components or by some connection wizards or by both. Due to license restrictions, Talend may not be able to ship some of these external modules within Talend Studio since 6.0.
Have you tried to install required external module for your Studio to functional properly?
Here is online document about:TalendHelpCenter:Installing external modules
