[Solved]-Change EJB project to web app-eclipse

i was able to remove the java ee facets by manually editing the .project file, changing the natures to remove the java ee natures:

<natures>
    <nature>org.eclipse.jdt.core.javanature</nature>
    <nature>org.eclipse.m2e.core.maven2nature</nature>
    <nature>org.eclipse.mylyn.wikitext.ui.wikitextnature</nature>
</natures>
