Hi This is exactly what I was talking about. Finding something in the code that distinguishes the versions. However this is only step one. Next is to figure out which implementation (MyFaces, RI). Here one only needs to try an do a class.forName on a class in each and check for exceptions.

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) <[EMAIL PROTECTED]> 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 <[EMAIL PROTECTED]> wrote: > > I've been trying to determine a better strategy for detecting the supplier and version of the JSF runtime. This has to do with a open JIRA ticket [1]. I attempted to create a utility class to determine the implementor of the runtime and the JSF spec version [2]. This was a real hack but I didn't see a better way and I'm still not sure the best way to dynamically extract this version information. Besides knowing the JSF version (1.1, 1.2), we need the implementation version (myfaces 1.1, 1.3...). I was thinking about trying to read the manifest but haven't figured out a good method. This seems like it should be part of the JSF API? > > > Any ideas? > > Gary > > > [1] https://issues.apache.org/struts/browse/SHALE-418 > [2] https://svn.apache.org/viewvc/shale/framework/trunk/shale-clay/src/main/java /org/apache/shale/clay/utils/JSFRuntimeTracker.java?view=markup
