How to change an html property depending on the value of a profile collected from java class

As I imagined it was simple, only that having no experience and not having touched this never happen these things. In the same jsp I import the library where I have the method with which I capture the profile:

    <%@ page import="java.util.*" %>
    <%@ page import="libreria.capturar.perfil.*"%>

This is the way to write java code in jsp and import libraries, we will continue to see it (I am referring to <%% > [I did not know it]).

Now I write the change that my code has suffered by knowing how to write java in jsp and how to capture the profile to make the condition:

    <tr>
        <td>
            <bean:message key="depen.insert.alas"/>
        </td>
        <td>
            <%String p = P.getP(request);
            if(p.equals("Admin")){%>
                  <html:text readonly="false" property="alas">
                  </html:text>
            <%}else{%>
                  <html:text readonly="true" property="alas">
                  </html:text>
            <%}%>
        </td>
    </tr>

I hope it can help someone lost as I help in the future.

Is your text box a input or a testarea ? In any case you have the property disabled that specifies whether it is enabled or not.

<input type="text" name="name" disabled>
<textarea disabled>Loren ipsum dolor sit..</textarea>

In jsp I think you have the property disabled and the property readonly that accept a boleado value.

<html:text readonly="true" disabled="true" ></html:text>

You can make a condition that checks the type of profile and enable or not depending on your needs. I have never worked with jsp, but I think it would work something like that.

var deshabitado = false
if (p === a) {
  deshabitado = true
} else {
  deshabitado = false
}
<html:text disabled="<%= deshabitado %>" ></html:text>
