[jboss-dev-forums] [JBoss ESB Development] - Dynamic Routing by code via HttpRouter without ConfigTree po

[h.wolffenbuttel]

Hi,

The JBoss ESB has various routing possibilities, but no dynamicaly configurated HTTPRouter (as far as I know). I need contentbased message routing without having to declare each and every http-endpoint in the jboss-esb.xml. 

There are two options I see here without any ESB changes:
- Rewrite HttpRouter class and others to accept Properties instead of a ConfigTree.
- Rewrite ConfigTree class making it possible to programmaticaly add nodes
- Instantiate the HttpRouter with a hard coded xmlstring (See code example)


  |  public Message sendAnswer(Message message) throws ActionProcessingException{
  |     String responseUrl = (String)message.getBody().get("ResponseUrl");
  |     String responseOperation = (String)message.getBody().get("ResponseOperation");
  |     String responseSoapAction = (String)message.getBody().get("ResponseSoapAction");
  |     String xml = 
  |     "<action class=\"nl.gouwit.esb.actions.HttpDynamicRouter\" name=\"SendAnswerAction\" endpointUrl=\"" + responseUrl + "\"" 
  |     + " method=\"POST\" responseType=\"STRING\"\">"    
  |     + "<header name=\"SOAPAction\" value=\""+responseSoapAction+"\"/>"
  |     + "<header name=\"operation\" value=\""+responseOperation +"\"/>"    
  |     + "</action>";     
  |     try {
  |       ConfigTree config = ConfigTree.fromXml(xml);
  |       HttpRouter router = new HttpRouter(config );
  |       router.process(message);
  |     }
  |     catch (ConfigurationException e) {
  |       throw new ActionProcessingException(e);
  |     }
  |     catch (SAXException e) {
  |       throw new ActionProcessingException(e);
  |     }
  |     return message;
  |   }
  | 

This code works, but I prefer have a solution where I do not need to create a config by converting XML. I also don't prefer to write my own httprouter because I want to use the ESB functionality as much as possible. Also I don't want to miss out on any newly added functionality to the ESB.
