java - Quartz RMI remote server returning invalid hostname -

-

i have 2 processes on separate servers. 1 running quartz scheduler , want connect other manage triggers.

on scheduler server config is:

org.quartz.scheduler.rmi.export = true org.quartz.scheduler.rmi.createregistry = org.quartz.scheduler.rmi.registryhost = localhost org.quartz.scheduler.rmi.registryport = 1099 org.quartz.scheduler.rmi.serverport = 1100

on remote server config is:

org.quartz.scheduler.rmi.proxy = true org.quartz.scheduler.rmi.registryhost = ip-172-16-5-11.eu-west-1.compute.internal org.quartz.scheduler.rmi.registryport = 1099

when try , connect remote scheduler following error in log:

error [2016-07-28 09:10:23,017] xxxx: error communicating remote scheduler. ! java.net.connectexception: connection refused ! ... 83 common frames omitted ! causing: java.rmi.connectexception: connection refused host: log-emea-1; nested exception is: ! java.net.connectexception: connection refused

although host host on our network have no idea why being returned remote registry.

there no connectivity issues. if run tcpdump on remote machine can see connecting scheduler. it's scheduler returning invalid host:

09:19:02.047589 ip 172.16.5.11.1099 > 172.16.0.81.54065: flags [p.], seq 19:235, ack 105, win 210, options [nop,nop,ts val 1231389006 ecr 562121102], length 216 e.....@.@..........q.k.1}.z... ......c..... ie.n!.i.q....w..9.e2...v0.|...sr.$org.quartz.core.quartzscheduler_stub...........pxr..java.rmi.server.remotestub......e....pxr..java.rmi.server.remoteobject.a...a3....pxpw3. unicastref. log-emea-1...l/8.   .a.69.e2...v0.|....x

where quartz rmi registry getting hostname from? there no clues in hosts file or dns. appears random.

you start scheduler following jvm-flag

java -djava.rmi.server.hostname=...

(see rmi-faq or why java rmi keep connecting 127.0.1.1. when ip 192.168.x.x?)

Android volley - avoid multiple requests of the same kind to the server? -

-
i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response
