Recuperar parametro da sessão na JSP

Olá, preciso recuperar um parametro que está na sessão coloca-lo em uma hidden...fiz desse jeito mas o resultado foi o erro abaixo... alguem sabe como posso fazer isso???
Grato.

Meu Codigo Atual:

&lt;%@ taglib uri=&quot;http&#58;//jakarta.apache.org/struts/tags-bean&quot; prefix=&quot;bean&quot; %&gt;
&lt;%@ taglib uri=&quot;http&#58;//jakarta.apache.org/struts/tags-html&quot; prefix=&quot;html&quot; %&gt;
&lt;%@ taglib uri=&quot;http&#58;//jakarta.apache.org/struts/tags-logic&quot; prefix=&quot;logic&quot; %&gt;

&lt;%@page contentType=&quot;text/html&quot;%&gt;
&lt;%@page pageEncoding=&quot;UTF-8&quot;%&gt;

&lt;html&#58;html&gt;

    &lt;head        
        &lt;title&gt;Inserir nova operação&lt;/title&gt;
    &lt;/head&gt;
    
    &lt;body&gt;

    &lt;jsp&#58;include page=&quot;cabeçalho.jsp&quot;/&gt;
    
    &lt;p align=&quot;center&quot;&gt;&amp;nbsp;&lt;/p&gt;
      
    &lt;p align=&quot;center&quot;&gt;&lt;b&gt;&lt;font face=&quot;Century Gothic&quot; size=&quot;5&quot; color=&quot;#FFFFFF&quot;&gt;
      Cadastrar nova Operação&#58;&lt;/font&gt;&lt;/b&gt;
    &lt;/p&gt;
     
    &lt;p align=&quot;center&quot;&gt;&amp;nbsp;&lt;/p&gt;
    
    
    
    &lt;html&#58;form action=&quot;/salvaInsereOpe.do&quot;&gt;
    
     &lt;%= session.getAttribute&#40;&quot;Id&quot;&#41;%&gt;
    
       &#91;b&#93;&lt;html&#58;hidden property=&quot;codUsuario&quot; value = &quot;&lt;%= session.getAttribute&#40;&quot;Id&quot;&#41;%&gt;&quot;/&gt; &#91;/b&#93;    
       Descrição&#58; &lt;html&#58;text property=&quot;descricao&quot;/&gt;
       
      &lt;html&#58;radio property=&quot;tipoOperacao&quot; value=&quot;1&quot;&gt;Despesa&lt;/html&#58;radio&gt;
      &lt;html&#58;radio property=&quot;tipoOperacao&quot; value=&quot;2&quot;&gt;Receita&lt;/html&#58;radio&gt;
      
      &lt;html&#58;radio property=&quot;ativo&quot; value=&quot;1&quot; &gt;Ativo&lt;/html&#58;radio&gt;
      &lt;html&#58;radio property=&quot;ativo&quot; value=&quot;2&quot; &gt;Inativo&lt;/html&#58;radio&gt;

                                
                          
                                
    &lt;/span&gt;&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
    &lt;p align=&quot;center&quot;&gt;&amp;nbsp;&lt;/p&gt;
  
    
    
    
    
    
     &lt;p align=&quot;center&quot;&gt;&lt;b&gt;&lt;font face=&quot;Century Gothic&quot;&gt;&lt;html&#58;submit&gt;Cadastrar&lt;/html&#58;submit&gt;&lt;/a&gt;&lt;/font&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt; 

    
                             &lt;%-- exibe os erros de validação --%&gt; 
                                  &lt;/font&gt;&lt;/b&gt;
                                &lt;logic&#58;messagesPresent&gt;
                                    &lt;/p&gt;
                                    &lt;ul&gt;
                                        &lt;font color=&quot;red&quot;&gt;&lt;font size=&quot;2&quot; face=&quot;Century Gothic&quot;&gt;
                                        &lt;html&#58;messages id=&quot;error&quot;&gt;
                                            &lt;li&gt;
                                            &lt;p align=&quot;center&quot;&gt;&lt;bean&#58;write name=&quot;error&quot;/&gt;&lt;/li&gt;
                                        &lt;/html&#58;messages&gt;
                                    &lt;/ul&gt;
                                &lt;/logic&#58;messagesPresent&gt;
    
    &lt;/html&#58;form&gt;
       
    &lt;/body&gt;
&lt;/html&#58;html&gt;
