FormLoginDemo.java
Hello all,
I am a newbie to httpclient. I am trying to pass xml string from my struts web application to cocoon web application. Please note that they are two separate applications. I am using httpclient to connect them. I created a httpclient in my struts app action, set the host address of cocoon web application and try to connect. The result is that it will connect and the status code is OK. However, it will not start a browser with the destination URL. I am wondering whether httpclient does have the functionality of opening up a new browser window. I read more docs on httpclient and find that there is no mentioning of opeinging up a new browser window. My question is whether it will open a new browser window after I connect to the new url. Please help!!

As Ortwin said HttpClient does not provide any GUI functionality. It is
just a library for communicating over HTTP. If you want the end user's
browser to redirect to the URL returned from Cocoon you will need to
return a redirect from your Struts Action.execute() method. I'm
guessing this might have problems though as the client's browser will
not have the cookies used by HttpClient.

Yan,
HttpClient is a server side application without any graphical user
interface. It is supposed to transfer data to and from any Http Server.
The dealing with the data is considered the responsibility of the user
(you).
So your servlet will probably need to pass the output from cocoon
through to the ServletOutputStream.
