I have an Ajax.Request call
new Ajax.Request(getURL()+''/context/className.finder'', {
method:''post'',
parameters:
''session=htc&tra=''+tra+''&curPg=''+$
(''curPg'').getValue()+
''&tabType=''+$(''tabType'').getValue()+
''&fiditcd=''+$(''fiditcd'').getValue()
+''&itcdqs=''+itcdqs,
requestHeaders: {Accept: ''application/json''},
evalJSON: ''force'',
onSuccess: function(transport){
var json = transport.responseJSON;
if (json != null) {
if (json.error == undefined) {
$(''main'').hide();
$(''listTable'').hide();
$(''add'').show();
var table FinderTable.buildTable(json);
$(''finderResults'').update();
$(''finderResults'').insert(table);
} else {
buildErrorScreen(json);
}
}
$(''loaderGif'').hide();
$(''copygen'').hide();
}
});
When hitting this Ajax call over an over again, using IE in a fast
unusual manner, Weblogic 9.2 will through the following Exception:
<Error> <Socket> <BEA-000403> <IOException occurred on
socket:
java.net.SocketException: Connection refused.
java.net.SocketException: Connection refused
at java.net.SocketInputStream.socketRead0(Native Method)
at java.net.SocketInputStream.read(SocketInputStream.java:129)
at
weblogic.socket.SocketMuxer.readReadySocketOnce(SocketMuxer.java:826)
at
weblogic.socket.SocketMuxer.readReadySocket(SocketMuxer.java:802)
at
weblogic.socket.DevPollSocketMuxer.processSockets(DevPollSocketMuxer.java:
120)
Truncated. see log file for complete stacktrace
I was wondering if anyone else has experienced this? The application
sees no ill affect but our log files are getting filled up.
This is my first time working with Prototype and I like how the Ajax
calls are easier to do. In my previous work with XMLHTTPRequest I
never had this issue.
Is there a way to handle a socket connections to open to only one port
and stay connected? Or should a new port be opened on every
connection? Any help would be appreciated thanks.

Re: Ajax.Request causing Socket Exception on Weblogic 9.2
Hi,> <Error> <Socket> <BEA-000403> <IOException occurred on socket: > java.net.SocketException: Connection refused.My suspicion is that this a weblogic thing rather than a Prototype thing. There''s something about what you''re doing that weblogic doesn''t like and so it periodically refuses the connection. This could be it rate-limiting individual clients, or being overloaded, or...> Is there a way to handle a socket connections to open to only one port > and stay connected?
