The Oracle Application Framework provides the Link bean so that you can redirect the control to any other page once the Link bean has been clicked. The link bean item style creates an HTML link tag which can then be redirected to some other page as required.
To open a new browser on the click of the link bean from an OAF page you just need to make the target property of the link bean to _blank.
Corresponding web bean: OALinkBean
