I have begun to include Java RPC components of qooxdoo for my website and
application and have encountered a peculiar error (at least peculiar to me,
being a novice at some of these issues). I have copied line-for-line the
Java RPC example in SVN and deployed the servlet via Eclipse 3.3 (where I
built the servlet) and Tomcat 6.x (where the servlet is served). To all
outward appearances the servlet is running. That is, the URL "
http://localhost:8080/qooxdoo/.qxrpc"; yields no errors or warnings and the
server displays a few lines of code when the URL is invoked (see included
below in the post scriptum, for reference). I have similarly copied the
sample RPC code from here <http://qooxdoo.org/documentation/0.8/rpc> into my
qooxdoo application, including the error-handling. I have properly re-built
the application to include the RPC classes (without incident), but upon load
of the webpage in Firefox qooxdoo attempts to make an asynchronous call to
qooxdoo.test (the test class included in the Java RPC example) and there is
an exception from the RPC handler (displayed in the alert box):
origin: 3; code: 0; message: Unknown status code
According to the origin number it would appear there is a problem with the
communication layer (qx.io.remote.Rpc.origin.transport), but I do not know
what would cause a code 0. Now, opening the webpage in IE 6 yields a more
coherent error:
origin: 3; code: 500; message: Server error
I do not know if it is a bug or not that IE and Firefox give different
errors (they certainly prefer to act differently enough all the time as it
is), or if the problem is on my end. Clearly there seems to be come problems
on my end with the server (and indeed that may be the whole problem), but I
wanted to ask the broader community about the two different messages for the
same to see if there might be anything else lurking under the surface that I
may have overlooked.
Best,
Joseph Gangestad
P.S.
The line output by Tomcat after invocation of "
http://localhost:8080/qooxdoo/.qxrpc"; in Firefox is:
if (!qx || !qx.core || !qx.core.ServerSettings)
{qx.OO.defineClass("qx.core.ServerSettings");}qx.core.ServerSettings.serverPathPrefix
= "http://localhost:8080/qooxdoo";qx.core.ServerSettings.serverPathSuffix
=
";jsessionid=00A44FA881EAAC9E83AF39939D12A1EE";qx.core.ServerSettings.sessionTimeoutInSeconds
= 1800;qx.core.ServerSettings.lastSessionRefresh = (new
Date()).getTime();
