Can this be converted to use EL ? If so, how ?

Question

I am new to JSP / JSTL / EL. I am trying to convert existing code written by someone else from scriptlets to EL. (The code uses the displaytag tag library for tables.)
I cannot figure out how to convert line 122: mbeanServer.getAttribute() takes two parameters
Object      getAttribute(ObjectName name, String attribute)
Is it possible to convert getAttribute() with multiple parameters to EL... ?
If so can someone post an example of how to do it.
If not... can someone let me know
Any help is appreciated. I tried some things to convert
getAttribute( x, y ) but get error "The function xx must be used with a prefix when a default namespace is not specified"
Here is the code to convert to EL: ( 119-136)
52 <%
53 MBeanInfo mbInfo = (MBeanInfo)session.getAttribute(JmxAction.MBEAN_INFO);
54 ObjectInstance mbInstance = (ObjectInstance)session.getAttribute(JmxAction.MBEAN_OBJECT_INSTANCE);
55 MBeanServer mbServer = (MBeanServer)session.getAttribute(JmxAction.MBEAN_SERVER_ATTR);
56 MBeanAttributeInfo[] attributes = (MBeanAttributeInfo[])session.getAttribute(JmxAction.MBEAN_ATTRIBUTES);
57 request.setAttribute("attributes", attributes);
58 MBeanOperationInfo[] operations = (MBeanOperationInfo[])session.getAttribute(JmxAction.MBEAN_OPERATIONS);
59 request.setAttribute("operations", operations);
60 %>
119 <display:column
120 title="Value">
121 <%
122 Object value = mbServer.getAttribute(mbInstance.getObjectName(), (String)pageContext.getAttribute("attributeName")) ;
123 if(value != null && value.getClass().isArray())
124 {
125 Object[] values = (Object[])value;
126 for(int i = 0; i < values.length; i++)
127 {
128 out.print(values[i] + "<br>");
129 }
130 } else
131 {
132 out.print(value);
133 }
134 %>
135 </display:column>
136 </display:table>

Answer 1

Is it possible to convert getAttribute() with multiple parameters to EL... ? No, not directly.
EL can only access standard getter/setters. It can not call methods that take arguments.
Workarounds
- write a "wrapper" class that provides an interface to the MBeanServer object that EL can access
- if you have JSP2.0 you should be able to do it with a function
