<logic:iterate id="msgg" name="messages">
<tr>
<td>${msgg.messageNumber}</td>
<td>${msgg.from[0]}</td>
** <td><html:link action="msgbody?message=${msgg.message}">${msgg.subject}</html:link> </td>
<td>${msgg.sentDate}</td>

import org.apache.struts.action.ActionForm;

public void setMessage(Message message) {
this.message = message;

Of course it's a String. It's being passed as a request parameter. Request parameters are always Strings.
It looks like something needs to be held in the session maybe?
