Please, help with response.sendRedirect

[Eduardo Godoy <eg...@tekchile.cl>]

Please, I have been fighting with this code so long ...

<?xml version="1.0"?>
<?cocoon-process type="xsp"?>
<?cocoon-process type="xslt"?>
<?cocoon-disable-caching?>
<xsp:page languaje="java" xmlns:xsp="http://apache.org/xsp" xmlns:log="http://apache.org/xsp/log/2.0" xmlns:xsp-request="http://apache.org/xsp/request/2.0" xmlns:xsp-cookie="http://apache.org/xsp/cookie/2.0">

      <xsp:include>org.apache.cocoon.environment.Cookie</xsp:include>
      <xsp:include>org.apache.cocoon.environment.HttpEnvironment</xsp:include>
    </xsp:structure>
    <page>
        <header/>
        <title>Login</title>
        <content>
        <xsp:logic>
                String cookiename = "CM-Queue";
  String queue = <xsp-request:get-parameter name="queue_name"/>;
        if (!("".equals(queue))){
                <xsp-cookie:cookie>
                        <xsp-cookie:name><xsp:expr>cookiename</xsp:expr></xsp-cookie:name>
                        <xsp-cookie:value><xsp:expr>queue</xsp:expr></xsp-cookie:value>
                        <!--24*60*60-->
                        <xsp-cookie:setMaxAge>2*60</xsp-cookie:setMaxAge>
                </xsp-cookie:cookie>
               response.sendRedirect("http://www.yahoo.com");
          }
 </xsp:logic>
....
(the rest)
 </page>
</xsp:page>

If I comment the line 
response.sendRedirect("http://www.yahoo.com");
it works ... 

What's wrong about it?

Thanks
Eduardo.
