Java EE (Java Enterprise Edition) General Discussion

Im using c:import and c:param together to include a jsp file. Like this:
<c:import url="/test/Includer/rubriker.jsp" >
<c:param name="rubrik" value="${text.rubrik}"/>
</c:import>

But when i print the param to the jsp import page some characters becomes unreadable. I get characters like +,% and so on...why?
