How to invoke a function with arguments in JSTL expressions

Question

Hi ,
I want to know how to send arguments in the JSTL expression.
I have a scenario like this
for (int i=0; i<nicList.size(); i++)
                      NavigationItemControl nic = nicList.get(i);
                      ni = nic.getNavigationItem();
                      //scr
                      if (nic.isAvailable(Mask.SYSTEM))
                      { %>
                        <option value="<%=ni.getInternalHandle()%>"  <% if(pi.getNavigationItemHandle().equals(ni.getInternalHandle())) {%>selected<%}%> ><%=nic.getLabel()%></option>
                      <%
                    }   I was changed these code into JSTL ,the new one is
<c:forEach var="nic" items="${nicList}">                                             
                                             <c:set var="ni" value="${nic.navigationItem}"/>
                                             <c:set var="nicAvailableMaskSystem" value="${*nic.available*}"/>
                                             <c:set var="navigationItemHandle" value="true" />                                             
                                                  <c:if test="${nicAvailableMaskSystem}">
                                                       <option <c:if test="${pi.navigationItemHandle==ni.internalHandle}">  selected </c:if> value="${ni.internalHandle}" >
                                                                 ${nic.label}
                                                       </option>
                                                  </c:if>
                                        </c:forEach>in the above code I have problem with nic.isAvailable(Mask.SYSTEM),
Can any one help me on this how can I invoke a function in JSTL with arguments.

JSTL can only handle getter/setter methods. You can't pass parameters to the methods.
There are a couple of ways around this
1 - set up "mask" as a seperate attribute of the NavigationItemControl bean.
ie getMask() setMask()
and then have your isAvailable method as
  public boolean isAvailable(){
    return internalIsAvailable(getMask());
  }Another solution is to define a static function and invoke it as a function.
public static boolean navigationAvailable(NavigationItemControl, Mask);
What does the isAvailable() method do? How complicated is it?
Hope this helps,
