[Axis2] NullPointerException in OutInAxisOperationClient
Hi all,
I'm trying to send a message from a web service A to a web service B,
but I get this exception:
ERROR
ncl.qosp.controller.scheduler.weighted.WeightedAvgRespTimeServiceHandler
- java.lang.NullPointerException
at
org.apache.axis2.description.OutInAxisOperationClient.execute(OutInAxisOperation.java:260)
at org.apache.axis2.client.ServiceClient.sendRobust(ServiceClient.java:350)
at org.apache.axis2.client.ServiceClient.sendRobust(ServiceClient.java:330)
at
ncl.qosp.controller.scheduler.weighted.WeightedAvgRespTimeServiceHandler.client(WeightedAvgRespTimeServiceHandler.java:609)
at
ncl.qosp.controller.scheduler.weighted.WeightedAvgRespTimeServiceHandler.send(WeightedAvgRespTimeServiceHandler.java:560)
at
ncl.qosp.controller.scheduler.weighted.WeightedAvgRespTimeServiceHandler.addResource(WeightedAvgRespTimeServiceHandler.java:333)
at
ncl.qosp.controller.scheduler.weighted.WeightedAvgRespTimeScheduler.requireResources(WeightedAvgRespTimeScheduler.java:296)
at
ncl.qosp.controller.scheduler.weighted.WeightedAvgRespTimeServiceHandler.setOptimalValue(WeightedAvgRespTimeServiceHandler.java:284)
at
ncl.qosp.controller.scheduler.weighted.WeightedAvgRespTimeScheduler$ReminderTask.reallocateResources(WeightedAvgRespTimeScheduler.java:549)
at
ncl.qosp.controller.scheduler.weighted.WeightedAvgRespTimeScheduler$ReminderTask.run(WeightedAvgRespTimeScheduler.java:519)
at java.util.TimerThread.mainLoop(Timer.java:512)
at java.util.TimerThread.run(Timer.java:462)
The chunk of code generating the above exception is:
EndpointReference targetEPR = new EndpointReference(target);
Options options = new Options();
options.setTo(targetEPR);
options.setAction("urn:echo");
options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
options.setUseSeparateListener(true);
ServiceClient sender = new ServiceClient();
sender.engageModule(new QName(Constants.MODULE_ADDRESSING));
sender.setOptions(options);
try {
sender.sendRobust(r.request);
} catch (Exception e) {
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
e.printStackTrace(pw);
log.error(sw.getBuffer().toString());
pw.close();
}
Please note that this code works if a sendReceiveNonBlocking() call is
used instead of sendRobust().
Should I create a JIRA?

Yes please create a JIRA , to be honest , we need to improve sendRobest
invocation , its seems buggy .
