{code}

and if i add

{code}
<dependency>
            <groupId>org.jboss.spec.javax.faces</groupId>
            <artifactId>jboss-jsf-api_2.1_spec</artifactId>
        </dependency>
{code}

then no error .

the difference is in the above case i will find the jar in EAR but with provided i will not . and actually m using manifest to put required jars on classppath so that EJB can use them from EAR.

if its provided then maven will not add that to manifest.

so what to do , to put jar in manifest when its provided in pom ??? or something else is the case ???

Please clear this doubt .

help !!

THanks

The JSF api's are only made available to web modules. If you reference them in EJBs or utility classes in the EAR you will get CNFEs.

If you have a look at AS71 Class Loading in AS7, you should be able to figure out how to make the module containing the JSF classes available to the rest of your application.

hi,

Thanks for the reply .

yes its correct , they are for web module . but if m referencing them in EJB , m also providing dependency .

and my concern was adding in pom with provided so not to add  in EAR package and put on manifest so it become available.

i will go through your link .

thanks

hi,

we can put a manifest entry for jsf-api in pom.xml to make it available as provided. THen only it will be given by jboss 7 . normally only provided to web- module.

Thanks
