You must have configured system bundle to export javax.servlet package
for embedded Felix. What class loader have you configured as the parent
class loader for embedded Felix? Try setting
org.osgi.framework.bundle.parent=framework
in your felix config file.
Having said that why would you embed Felix in your webapp deployed in
GlassFish v3 when GlassFish v3 is already deployed inside Felix? Your
web app can already be deployed as an OSGi bundle allowing it to take
advantage of both Java EE and OSGi APIs.
