Hmm, why you need it so verbose?

I would create a small java helper class that is doing the conversion
(URLHexEncoder.java#encode(string)), then you can write an input module
that is using the helper to calculate the url encoding and/or using it
from a jx page.

URLHexEncoder.java

public class URLHexEncoder {
 public static String encode(String url){
  String resultUrl =3D null;
  //calculate your resultUrl and then
  return resultUrl;
 }
}

However there is org.apache.cocoon.util.NetUtils that may offer already
the decode/encode functionality you are looking for.

Then from an input module (URLHexEncoderModule.java)

public class URLHexEncoderModule extends AbstractInputModule {
  public Object getAttribute(String name, Configuration modeConf, Map
objectModel) throws ConfigurationException {
   return URLHexEncoder.encode(name);
 }
}

or from jx

<jx:set var=3D"hexUrl"
value=3D"${Packages.your.path.URLHexEncoder("URL")}"/>
