Subject: Re: question : encounter java.net.SocketTimeoutException: Read
timed out occasionally
Hi Johnny,
Yes, We are using ajax to make the post requests, and the header do
include
content-length information that was calculated by ajax automatically, but
the
strange thing is sometime it get stuck at the begin of uploading http
body(0
byte
was transfered always in this case) until AJP connector timeout, actually
we
have revised a little bit on tomcat source code, below is our finding we
made
the change on org.apache.catalina.connector.Request.java for your
reference
:
protected void parseParameters() {
: : : :
: : : :
if (actualLen == len) {
parameters.processParameters(formData, 0, len);
}
else { // added by me
context.getLogger().error("formData Len error len :" +
len + " <> actualLen :" + actualLen);
}
} catch (Throwable t) {
context.getLogger().warn
(sm.getString("coyoteRequest.parseParameters"), t);
}
}
}
Following was the Tomcat log, actualLen always return 0,
the first line showing the content-length is 32 but the returned
actual length is 0.
SEVERE: formData Len error len :32 <> actualLen :0
SEVERE: formData Len error len :379 <> actualLen :0
SEVERE: formData Len error len :32 <> actualLen :0
SEVERE: formData Len error len :41 <> actualLen :0
SEVERE: formData Len error len :60 <> actualLen :0
SEVERE: formData Len error len :74 <> actualLen :0
SEVERE: formData Len error len :145 <> actualLen :0
SEVERE: formData Len error len :60 <> actualLen :0
Thanks & Best Regards.

James... dont know... couple of thing you can do... get wire shark and
actually watch whats on the wire... if the header is coming in and no body
is sent, it aint tomcat...
My Ajax is stale... if you doing it yourself, then its very like a
javascript issue.... cant remember details but its not unusual in the Ajax
stuff to see...
... if(IE) do it all different...
... I think you working on the wrong side... its that Ajax, is my guess....
My guess is that it works with Firefox perfectly... but not on IE and you
dont have a debugger for that... welcome to Javascript ;) on diff browsers
its a nightmare ;)
Good luck, or maybe post the Ajax snippet and see if the guys can spot it...
