java - JSTL & Spring: Accessing methods with arguments

Question

I have an object with a method

  public boolean hasPermission(String role) {
   return permissions.contains(role);
  }

I want to do the equivalent of:

<c:if test="${row.hasPermission(role)}">
    <td></td>
</c:if>

But I cannot access the hasPermission method from within the JSP file. How can I do it?

Answer 1

The latest version of EL (in tomcat 7 for ex.) supports this (${obj.method(arg)})

If you have an older version you have two options:

• Make a custom JSTL function
• Use JBoss EL extension
