> Changing a service name doesn't update its TypeTable struct
> -----------------------------------------------------------
>
> Key: AXIS2-5745
> URL: https://issues.apache.org/jira/browse/AXIS2-5745
> Project: Axis2
> Issue Type: Bug
> Components: kernel
> Affects Versions: 1.6.2
> Environment: Windows 8.1 x86-64, Tomcat 7.0.68 x86-64
> Reporter: Thorsten Schöning
> Priority: Major
> Attachments: WsAxis2SvcLc.java

>
> I have an implementation of ServiceLifeCycle in which I'm overriding startUp
> and change the name of my service in some special way to make my deployment
> easier. I'm simply implementing some kind of mandator mechanism based on
> exploded services and their unique name in the file system.
> This worked pretty fine the last years, but today I encountered that Axis2 is
> handling structures internally in which the service name is used as some
> component of a key. Those structures were built before startUp was called and
> were not updated on a changed service name. My service generated an exception
> for some reason, Axis2 tried to handle that and failed itself with a NPE,
> which made debugging pretty hard of course because the original exception was
> lost.
> The NPE was thrown in the following line 183 of RPCMessageReceiver and the
> not up to date structure was TypeTable for the service, that's why
> elementQName was null instead of a valid object. Gladly I was able to access
> that map in my ServiceLifeCycle implementation and update the generated keys
> and QNames with my new updated service name. I would have expected that if
> I'm able to change the service name, structs containing it would get updated
> automatically by Axis 2, which at least for TypeTable currently isn't the
> case.

> I'm currently unable to build Axis2 from src and am not sure where one would
> implement such a change, therefore can't provide patches, but instead I'll
> simply post my implemantation of the change for TypeTable in my
> ServiceLifeCycle. In my case, TypeTable contained the following data for my
> old service name "SoapAuth":
> {CODE}
> complexTypeMap HashMap<K,V> (id=165)
