Using Tomcat 7.0.47 via TomEE 1.6.0 along with MyFaces 2.1.13 Recently, I have been experiencing the SocketTimeoutException when web application is serving resources to 'mobile clients'. Yesterday, user was attempting to login from mobile iPad via an internal wireless phone connection. Since my web application is accessed by mobile clients and since I started using TomEE (tomcat7 and myfaces), I have seen the 'Error trying to load resource ...' (below), but I have not seen the SocketTimeoutException until I recently started using Tomcat 7.0.47 and MyFaces 2.1.13.
I saved the first occurrence (Nov 8, 2013) of this exception on gist[1] and saved Nov 9, 2013 occurrence on gist as well. I do have a web/servlet filter in place, and I assume that I can catch the SocketTimeoutException (when client is mobile) to prevent the stacktrace in the log, but this exception is 'now' being logged to tomcat7-stderr, but this SocketTimeoutException was not logged with previous versions of Tomcat 7.0.x and MyFaces 2.1.x. I assume that this is new logging behavior of MyFaces 2.1.13 (or there is something new about Tomcat 7.0.47) but I may be mistaking. Please see all below, and advise how I can prevent this exception, if I can adjust some tomcat settings to increase the socket timeout value, or recommendations about serving resources to 'mobile clients'. I'm thinking that I can increase the expiration of client resources from my web/servlet filter, so this will not occur as often. This exception does not occur everytime, but i'm sure you can understand that this 'can' happen frequently and sporadically, depending on the connection between server and mobile-device-via-wireless-phone-connection. localhost_access_log shows the follow (please note the filenames and time difference between the 1, 2, and 3rd lines below) x.x.x.x - - [09/Nov/2013:13:08:25 -0500] "GET /webapp/javax.faces.resource/primefaces.css.jsf?ln=primefaces&v=4.0.3 HTTP/1.1" 200 10036 x.x.x.x - - [09/Nov/2013:13:09:00 -0500] "GET /webapp/javax.faces.resource/jquery/jquery.js.jsf?ln=primefaces&v=4.0.3 HTTP/1.1" 200 - x.x.x.x - - [09/Nov/2013:13:09:00 -0500] "GET /webapp/javax.faces.resource/jquery/jquery-plugins.js.jsf?ln=primefaces&v=4.0.3 HTTP/1.1" 200 - tomcat7-stderr Nov 09, 2013 1:09:00 PM org.apache.myfaces.application.ResourceHandlerImpl handleResourceRequest SEVERE: Error trying to load resource jquery/jquery.js with library primefaces :null ClientAbortException: java.net.SocketTimeoutException at org.apache.catalina.connector.OutputBuffer.realWriteBytes(OutputBuffer.java:413) Caused by: java.net.SocketTimeoutException at org.apache.tomcat.util.net.NioBlockingSelector.write(NioBlockingSelector.java:127) at org.apache.tomcat.util.net.NioSelectorPool.write(NioSelectorPool.java:174) at org.apache.coyote.http11.InternalNioOutputBuffer.writeToSocket(InternalNioOutputBuffer.java:163) Nov 09, 2013 1:09:00 PM org.apache.myfaces.application.ResourceHandlerImpl handleResourceRequest SEVERE: Error trying to load resource jquery/jquery-plugins.js with library primefaces :null ClientAbortException: java.net.SocketTimeoutException Caused by: java.net.SocketTimeoutException at org.apache.tomcat.util.net.NioBlockingSelector.write(NioBlockingSelector.java:127) at org.apache.tomcat.util.net.NioSelectorPool.write(NioSelectorPool.java:174) at org.apache.coyote.http11.InternalNioOutputBuffer.writeToSocket(InternalNioOutputBuffer.java:163) [1] https://gist.github.com/smithh032772/7380812
