java - Jersey REST service throw Timeout exception -


we have jersey rest service, , rest client using spring's rest template, once in while noticed client got 500 internal server error rest service:

error: 500 internal server error; nested exception org.springframework.web.client.httpservererrorexception: 500 internal server error

when checking server's log found this:

org.apache.catalina.core.standardwrappervalve invoke severe: servlet.service() servlet [abc] in context path [] threw exception [javax.ws.rs.processingexception: java.net.connectexception: connection timed out (connection timed out)] root cause java.net.connectexception: connection timed out (connection timed out)     @ java.net.plainsocketimpl.socketconnect(native method)     @ java.net.abstractplainsocketimpl.doconnect(abstractplainsocketimpl.java:350)

i'm not sure problem here, server timeout or client got timeout? if it's client issue, can add retry, if it's server timeout?

the error connection timed out: means request did not response within specific time or in time period. , there many reasons time out our response bot in time period:

1) may ip address or port incorrect.

2) may ip address down.

3) server or host taking longer or more time specify time timeout.

4) may firewall of server or host blocking requests or port using.

5) internet access or local network issue or connectivity.

6) packet loss due wrong network configuration or traffic overload.

c) overloading of many requests issue @ host or server .

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

Why does math.random(999999999999) returns 1 in Lua? -

i tried: print(math.random(999999999999)) , has printed 1 . also math.random() includes 999999999999 printing same thing. examples: print(math.random(1.999999999999)) » 1 print(math.random(1999999999999)) » 1 for k,v in next,{math.random(999999999999), math.random(1999999999999), math.random(2.999999999999)} print(v) end » 1 local n = math.random(999999999999) print(n==1) » true then think understood (if know lua of course). can explain me? @edits: the lua version i'm using 5.2. i tried print(math.random(-999999999999)) , printed 111711452 . looks worked positive number. this problem surely because math.random treats input arguments passed in lua 5.1 and/or 5.2. [mathlib.c] 1 : as may know in c , standard int can represent values -2,147,483,648 2,147,483,647 . adding +1 2,147,483,647 , in use-case, overflow , wrap around value giving -2,147,483,648 . end result negative since you're multiplying positive negative number. ther...
