OT: Connection timeout with HttpClient
One of our legacy applications is using Apache Commons HttpClient 3.1. POST call to one REST service is failing with "java.net.ConnectException: Connection timed out: connect" exception[1]. Timeout is occurring after one minute. To figure out where thread is spending all the time, I took multiple thread dumps. In all of them, thread is trying to create secure socket[2]. I am not seeing any thread pool issue. Also the target REST service is working properly with same payload while invoked from Postman. It is only failing consistently when going through the HttpClient. I am trying to figure out why it is taking so long in connecting to the socket. I am looking for suggestion on how to attack this one.

You should upgrade ASAP. The connection timeout you are seeing is on the client end: your client is connecting to another server and the server isn't responding fast enough. That's why your stack trace always shows the thread "creating a socket": it's trying to connect to the remote service and it's never completing. Since it's failing on "connect" and not "read", it's likely that there is a firewall between your client and the service you are trying to connect to which is dropping all packets instead of returning a "connection refused" response. So this isn't a problem with your code or with Tomcat. It's a problem between your client (which has the stack trace below) and the service that code is trying to call. - -chris > > [1] java.net.ConnectException: Connection timed out: connect at > java.net.TwoStacksPlainSocketImpl.socketConnect(Native Method) at > java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.jav a:350) > > at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImp l.java:206) > at > java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java: 188) > > at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) > at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at > java.net.Socket.connect(Socket.java:589) at > sun.security.ssl.SSLSocketImpl.connect(SSLSocketImpl.java:668) at > sun.security.ssl.SSLSocketImpl.(SSLSocketImpl.java:472) at > sun.security.ssl.SSLSocketFactoryImpl.createSocket(SSLSocketFactoryImp l.java:153) > > at org.apache.commons.httpclient.protocol.SSLProtocolSocketFactory.createSo cket(SSLProtocolSocketFactory.java:82) > at > org.apache.commons.httpclient.protocol.SSLProtocolSocketFactory.create Socket(SSLProtocolSocketFactory.java:127) > > at org.apache.commons.httpclient.HttpConnection.open(HttpConnection.java:70 7) > at > org.apache.commons.httpclient.HttpMethodDirector.executeWithRetry(Http MethodDirector.java:387) > > at org.apache.commons.httpclient.HttpMethodDirector.executeMethod(HttpMetho dDirector.java:171) > at > org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java :397) > > at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:3 23) > > [2] "http-apr-18100-exec-5" #327 daemon prio=5 os_prio=0 > tid=0x2efbf800 nid=0x2508 runnable [0x2e55d000] > java.lang.Thread.State: RUNNABLE at > java.net.TwoStacksPlainSocketImpl.socketConnect(Native Method) at > java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.jav a:350) > > - - locked <0x00071a984780> (a java.net.TwoStacksPlainSocketImpl) > at > java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketI mpl.java:206) > > at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:18 8) > at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) at > java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at > java.net.Socket.connect(Socket.java:589) at > sun.security.ssl.SSLSocketImpl.connect(SSLSocketImpl.java:668) at > sun.security.ssl.SSLSocketImpl.(SSLSocketImpl.java:472) at > sun.security.ssl.SSLSocketFactoryImpl.createSocket(SSLSocketFactoryImp l.java:153) > > at org.apache.commons.httpclient.protocol.SSLProtocolSocketFactory.createSo cket(SSLProtocolSocketFactory.java:82) > at > org.apache.commons.httpclient.protocol.SSLProtocolSocketFactory.create Socket(SSLProtocolSocketFactory.java:127) > > at org.apache.commons.httpclient.HttpConnection.open(HttpConnection.java:70 7) > at > org.apache.commons.httpclient.HttpMethodDirector.executeWithRetry(Http MethodDirector.java:387) > > at org.apache.commons.httpclient.HttpMethodDirector.executeMethod(HttpMetho dDirector.java:171) > at > org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java :397) > > at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:3 23) > > - > > To unsubscribe, e-mail: users

why is ContextListener.attributeAdded means?
Dear experts,
I need some help again.
I am trying to get a html page out on my browser, I changed my Tomcat server as
the previous one has some Ant script 'creeping in when I downloaded an
example'. However, I do not know why am I receiving an error message ?
Background :-
-
Netbean IDE
Windows OS
Tomcat 9.0.12
JEE
Error Message :
24-Jul-2019 10:03:27.271 INFO [main]

Can I know why there is a ContextListner:attributeAdded('StockTicer',
'async.Stockticker@4fa4f485') as appeared in the log ?
How do I make it go away so that I can run my webApp ?
Thank you for your help.

Re: why is ContextListener.attributeAdded means?
Hi Goh,
It’s part of standard tomcat logging for servlet ctx init audit.
Check logging.properties file in your conf/ directory. You should be able
to change the level and tune how much logging is needed.
And btw, it’s an INFO, not ERROR/FATAL/SEVERE.
Thanks,

But, in my WebApp I don’t have this at all? So how did it creep into the log?
Is there some kind of script lying somewhere, accidentally crept in without me
knowing n some how make its way inside Tomcat...I know this sound abit over
imaginative but I really can’t tell for sure this attributeAdded is something
that comes with Tomcat
Thanks,

This is coming from the examples that are shipped with Tomcat. In
particular, this appears to be from the Stock Ticker asynchronous example.
In other words, this is nothing to be concerned about.
. . . just my two cents.
