The messager I`m getting when I Rebuild my project with JDeveloper ----

Error(5): "http://java.sun.com/jsp/jstl/core" is not a registered TLD namespace
Error(9): Unable to instantiate tag: sql:setDataSource (class: org.apache.taglibs.standard.tag.rt.sql.SetDataSourceTag)  Make sure that the tag class is available and that the tag library containing the class is not excluded from this application.
Error(10): Unable to find class for bean: null defined by tag with class: org.apache.taglibs.standard.tag.rt.sql.SetDataSourceTag

Thanks

Looks like you haven't set the datasource properly

its nothing to do with jstl, you need to define a datasource name 'inventaire' on the machine that the app server is running on.
