Calling function defined in JSP Page

I have defined a function something like below in the top of the jsp page

<%!
  public boolean isSkillSelcted(String Skill1)
  {
     ...
     .. 
     . 
     return true;
  }
%>

Now I want to call the Function in the Check box as below

<input name="chkSkills" type="checkbox" id="chkJava" value="Java" 
       <c:if test='${isSkillSelcted("Java") == true}'>Checked</c:if>>Java

If the function return true then the check box will be marked as checked.Its Displaying exception as below.

    org.apache.jasper.JasperException: /EditUser.jsp(73,71) 
The function isSkillSelcted must be used with a prefix when a default namespace is not specified

When i append fn at beginning fn:isSkillSelcted its complaining function undefined

enter image description here

The statement ${isSkillSelcted("Java")} is a call to an Expression Language function. When you use Expression Language function, you have to declare it in a .tld file, and to specify a prefix to use them. This is explained here.

If you declare your function in the JSP page, you have to call it like this :

  <input name="chkSkills" type="checkbox" id="chkJava" value="Java" 
  <% if (isSkillSelcted("Java")) { %>Checked<% } %> >
