Ability to create new LocalLBPool without any members through iControl Java API
I've been using the iControl Java (assembly) API to manage/configure the BigIP LTM instance (the virtual edition trial version). The management console of BigIP allows creating a LTM pool without any (initial) members added and just passing a load balancing method and a pool name. However, trying to do the same via the iControl Java API as follows results in an exception which isn't informative on why it's failing: final LocalLBPoolBindingStub localLBPool = (LocalLBPoolBindingStub) new LocalLBPoolLocator().getLocalLBPoolPort(this.bigIpLoadBalancerURL); localLBPool.create(new String[]{poolName}, new LocalLBLBMethod[]{loadBalancingMethod}, new CommonIPPortDefinition[0][0]); Notice that I am passing an empty array as the 3rd param to the create method. It fails with: Caused by: (500)Internal Server Error at org.apache.axis.transport.http.HTTPSender.readFromSocket(HTTPSender.java:744) at org.apache.axis.transport.http.HTTPSender.invoke(HTTPSender.java:144) at org.apache.axis.strategies.InvocationStrategy.visit(InvocationStrategy.java:32) at org.apache.axis.SimpleChain.doVisiting(SimpleChain.java:118) at org.apache.axis.SimpleChain.invoke(SimpleChain.java:83) at org.apache.axis.client.AxisClient.invoke(AxisClient.java:165) at org.apache.axis.client.Call.invokeEngine(Call.java:2784) at org.apache.axis.client.Call.invoke(Call.java:2767) at org.apache.axis.client.Call.invoke(Call.java:2443) at org.apache.axis.client.Call.invoke(Call.java:2366) at org.apache.axis.client.Call.invoke(Call.java:1812) at iControl.LocalLBPoolBindingStub.create(LocalLBPoolBindingStub.java:2429) and no more information. 1) Should it be possible to use iControl API to create a new pool without any (initial) members? From a BigIP point of view, I think it's possible since the UI allows you to do that. 2) Is there a way I can figure out what exactly the problem is with that method call? The error message isn't too informative.
