[jbossweb-commits] JBossWeb SVN: r560 - trunk/test/java/org/apache/jboss/web/comet.
Author: remy.maucherat(a)jboss.com
Date: 2008-03-27 17:13:09 -0400 (Thu, 27 Mar 2008)
New Revision: 560
Added:
trunk/test/java/org/apache/jboss/web/comet/CometServletTest2.java
Log:
- Reader and writer seem to work fine with Comet [but using a really large char[] could
cause problems
with the current code; I don't know if it's really legitimate with Comet as a
huge amount of data has
to be buffered, which is very costly]. Tested with chunked input.
Added: trunk/test/java/org/apache/jboss/web/comet/CometServletTest2.java
