I am setting up my first Stripes application and got most things working
well. I am currently stuck trying to read JSON from a jQuery POST.
I have http://www.charlesproxy.com/ Charles setup and can confirm the POST
to localhost and can see the post content as the JSON string I am sending.
The correct Stripes ActionBean handler is getting invoked but unfortunately,
when I try to read the stream - I get nothing.
Does Stripes possibly filter something like this? I'm not explicitly setting
much on the jQuery side (type or anything).
Javascript (jQuery):
$.post(url, '[[0,"2"],["2",-1]]');
Java:
@HandlesEvent("update")
@DefaultHandler
public Resolution updateState()
{
final StringBuffer buf = new StringBuffer();
String line = null;
try {
final BufferedReader reader =
getContext().getRequest().getReader();
line = reader.readLine();
while (line != null) {
buf.append(line);
line = reader.readLine();
}
StateBeanAction.LOG.info("StateBeanAction.updateState: " +
buf.toString());
return new StreamingResolution(MimeTypes.JSON, "");
} catch (final IOException e) {
final String msg = "Error tring to parse JSON state string. "
+ e.getMessage();
StateBeanAction.LOG.error(msg, e);
}
return null;
}
Charles:

[[0,"2"],["2",-1]]
I can set breakpoints and see log entries to confirm that the ActionBean is
hit. It's just that reader.readLine() is returning null on the first read.
Any thoughts would be appreciated. Thanks,
