To my casual glance, what you have seems workable.   It may be that your 
actual problem is generating the next page rather than collecting the data.  


In struts-config:
============
		<form-bean
            name="loginForm"
            type="org.apache.struts.validator.DynaValidatorForm">
            <form-property
                name="username"
                type="java.lang.String"/>
            <form-property
                name="password"
                type="java.lang.String"/>
		</form-bean
============

In my velocity page:
============
				<FORM method="POST" action="$link.setAction('LoginResult')">
					<strong>$msg.get("label.username"):</strong><BR /="">
					<INPUT type="text" name="username" value="$!{loginForm.username}" 
size="10" maxlength="32" class="login" id="userID" /><BR /="">
					<strong>$msg.get("label.password"):</strong><BR /="">
					<INPUT type="password" name="password" value="$!{loginForm.password}" 
size="10" maxlength="32" class="login" /><BR /="">
				</FORM>
============

In my Action, to read the data afterward:
============
		String userName = (String)((DynaValidatorForm)form).get("username");
		String password = (String)((DynaValidatorForm)form).get("password");
============


You can throw the following on your velocity page to see what's in the 
request context and verify that creationAdminOfForm exists:

<!-- request dump:
#foreach( $attribute in $request.attributeNames)
    $attribute
#end
-->
