JDT creating dynamic web project

I want to develop a plug-in in eclipse that create new dynamic web project. I create Java project and add project facet to convert it to dynamic web project, but it creates a static web project.

any help is appreciated

IJavaProject javaProject = createProject(projectName +"-web",new String[] {JavaCore.NATURE_ID});
       
        IFacetedProject facetedProject =
            ProjectFacetsManager.create(javaProject.getProject(), true, null);
       
        IProjectDescription description1 = javaProject.getProject().getDescription();
        description1.setNatureIds(new String[] {"org.eclipse.jem.workbench.JavaEMFNature",
                   "org.eclipse.wst.common.modulecore.ModuleCoreNature",
                   "org.eclipse.wst.common.project.facet.core.nature",
                   "org.eclipse.wst.jsdt.core.jsNature"});
       
        javaProject.getProject().setDescription(description1, null);

        IProjectFacet wstWebFacet = ProjectFacetsManager.getProjectFacet
        (IModuleConstants.WST_WEB_MODULE);

    facetedProject.installProjectFacet(wstWebFacet.getDefaultVersion(), null, null);
