Yeah, that's a real drag but I can't think of a better solution either. It will take some digging to figure out an API change or class that will distinguish a release. > Hermod > > > -----Opprinnelig melding----- > Fra: Mike Kienenberger [mailto:[EMAIL PROTECTED] > Sendt: 6. mars 2007 21:58 > Til: dev@shale.apache.org > Emne: Re: Determining the flavor of the JSF runtime > > Facelets has code to distinguish between JSF 1.1 and JSF 1.2. > > com.sun.facelets.util.FacesAPI. > > https://facelets.dev.java.net/source/browse/facelets/src/java/com/sun/facele > ts/util/FacesAPI.java > > As Kito mentioned, it also came up at one point that this should be > part of the JSF API. > > > > ---------- Forwarded message ---------- > From: Jesse Alexander (KBSA 21) > Date: Oct 28, 2005 9:15 AM > Subject: RE: How to find out which implementation is running > To: MyFaces Discussion , [EMAIL PROTECTED] > > > Well... > > I see two alternatives: > > 1) We add one/two method to javax.faces.application.Application > eg. getImplName() and getSpecVersion() > But that would require a spec change... > > 2) We ask that at startup one of the implementation classes adds > the information as a managedBean or a external-context variable > This could be added also without a spec change, just need to > agree with the RI-people on an identifier to use... > > regards > Alexander > > > -----Original Message----- > From: Martin Marinschek [mailto:[EMAIL PROTECTED] > Sent: Friday, October 28, 2005 4:07 PM > To: MyFaces Discussion > Subject: Re: How to find out which implementation is running > > Good question. > > If you devise something like this, there should also be a way to check > for the spec version of the jsf implementation running. > > regards, > > Martin > > On 10/28/05, Jesse Alexander (KBSA 21) > wrote: > > Hi > > > > When I want to write a component that must run under more than > > JSF-implementation, > > I often should know (runtime not development time) which > implementation > > is running, in > > order to use the correct base-classes. > > > > Has somebody devised a clever method to find out which JSF-runtime is > > active? > > Or should we add something to enable this? > > > > regards > > Alexander > > > On 3/6/07, Gary VanMatre wrote: > > > > I've been trying to determine a better strategy for detecting the supplier > and version of the JSF runtime.
