Hey, All...
I've been using Cocoon 2.0 for about a month & 1/2 now and
I've run into the following problem:
First off, refer to the Order example that comes with
cocoon which when you hit the submit, it will return the
xml typed into the textarea. Now, for testing, I've taken
my xml doc, modified the stream pipeline to use my
transform and then output html. Using the same form,
entered my xml text (cut & Paste from my text file) - hit
submit and it works like a charm - the generated HTML
comes back after the transform.
Now, the problem is in an application I'm writing that
needs to send the XML data as a parameter call to the
cocoon server and capture the resulting HTML. Using the
URL class and URLConnection class, I have to pass the
parameter (say "Foo") and the URLEncoder.encode value of
the parameter (URLEncoder.encode(some text))... The
problem is that the stream or cocoon doesn't see the
parameter passed in. Any ideas on how to get it to
understand the URLEncoded parameter.
Here's some example code:
StringBuffer uri = new
StringBuffer("http://localhost:8080/cocoon/request1";);
try {
URL url = new URL(uri.toString());
HttpURLConnection u_connect =
(HttpURLConnection)url.openConnection();
u_connect.setRequestMethod("POST");
u_connect.setDoOutput(true);
u_connect.setRequestProperty("Foo",
URLEncoder.encode(some text));
u_connect.connect();
// print out some results...
} catch (exceptions...) {}
Now, here's some of the output:
content length: 12341
content type : text/html
content encode: null
request method: POST
response code : 500
response mssg : Internal Server Error
e:java.lang.NullPointerException
So, in other words it gets there and then returns the
nullPointerException afterwards. Now, remember the text
is pure XML so that's why it needs encoding - the
URLConnection nor URL will accept it due to illegal
characters otherwise...
any help would be greatly appreciated...
peace. JOe...
