Proper way to get response with cometd java client in rc0.

[Thorbjørn Ravn Andersen]

I have a situation where I would like to push Java objects serialized
to XML across a cometd channel between two Java instances.

I have tried stripping the chat demo down to a simple program with a
MessageListener subscribing to a channel, and a sender routine. I
put the above XML string in a map and publish it. I get a map up in
the MessageLIstener with the proper key, but the value contains <
&gt; and &amp; instead of < > and &. This naturally causes the XML
deserialization to fail.

The full description with code snippets is on
http://stackoverflow.com/questions/1487126/proper-way-to-decode-response-in-dojo-cometd-java-client

I would like to know if I found a bug in the Java client or if I am
intended to decode the <, > and &'s myself? The libraries used is the
rc0 distribution.

Please advise,

Hi,

Please check that you're not using json filters: check for
WEB-INF/filters.json that does a bunch of default conversions, among
which the NoMarkupFilter.

It turned out I was not talking to the cometd web application I
thought I was, but to an earlier deployment of the chat room demo
server war, and _that_ used the NoMarkupFilter. Bummer :)

Thank you! That was a great help.
