Hi again, So to answer to people who could encounter the same problem as me: facelets is bundled with its ows JSTL implementation (you were right Volker ;-) that has nothing to do with the standard one except that it copies its syntax: https://facelets.dev.java.net/nonav/docs/dev/docbook.html#taglib-available-jstl .
The biggest probem is that where your <c:if goes when it's called isn't easy to follow at all. I realized it doesn't go into * com.sun.facelets.tag.jstl.core.**IfHandler* (added a breakpoint). A big mistake (in my opinion) is that facelets gives his implementation the same namespace as the one for standard JSTL: xmlns:c= http://java.sun.com/jsp/jstl/core This is a problem because the objective of namespaces is to distinguish between implementations of different types, it is amplified because wen you have a jstl jar in you classpath, the code is redirected to it (at least that's what happened to me) So even though I removed all my jars from my app jstl.jar (and standard.jar) files, JBoss has in its default libs jstl.jar that he puts for all applications. \JBoss\server\*default*\deploy\jboss-web.deployer\ (that is copied to JBoss\server\default\tmp\deploy) Even after removing this jar, my calls didn't redirect to *IfHandler*(surely another perverse jstl implementation somewhere) so to be radical I changed the namespace like this: I copied the init code in *JstlCoreLibrary *into my own library: package fr.into.common.functions; import java.lang.reflect.Method; import java.lang.reflect.Modifier; import com.sun.facelets.tag.AbstractTagLibrary; import com.sun.facelets.tag.jstl.core.CatchHandler; import com.sun.facelets.tag.jstl.core.ChooseHandler; import com.sun.facelets.tag.jstl.core.ChooseOtherwiseHandler; import com.sun.facelets.tag.jstl.core.ChooseWhenHandler; import com.sun.facelets.tag.jstl.core.ForEachHandler; import com.sun.facelets.tag.jstl.core.IfHandler; import com.sun.facelets.tag.jstl.core.SetHandler; public class CommonFunctionsTagLibrary extends AbstractTagLibrary { public static final String NAMESPACE = "http://www.into-i.fr/facelets/common/functions";; public static final CommonFunctionsTagLibrary INSTANCE = new CommonFunctionsTagLibrary(); public CommonFunctionsTagLibrary() { super( NAMESPACE ); try { Method[] methods = CommonFunctions.class.getMethods(); for( int i = 0; i < methods.length; i++ ) { if( Modifier.isStatic( methods[i].getModifiers() ) ) { addFunction( methods[i].getName(), methods[i] ); } } } catch( Exception e ) { throw new RuntimeException( e ); } this.addTagHandler( "if", IfHandler.class ); this.addTagHandler( "forEach", ForEachHandler.class ); this.addTagHandler( "catch", CatchHandler.class ); this.addTagHandler( "choose", ChooseHandler.class ); this.addTagHandler( "when", ChooseWhenHandler.class ); this.addTagHandler( "otherwise", ChooseOtherwiseHandler.class ); this.addTagHandler( "set", SetHandler.class ); } } see this link for creating your own libs: http://www.ibm.com/developerworks/java/library/j-facelets2.html So now I don't use the standard namespace anymore but it works.
