Subject [jira] Commented: (AXIS2-4910) [ERR 0635] Sporadically from org.apache.axis2.wsdl.WSDL2Code followed by failing compilations using generated code

William Walsh commented on AXIS2-4910:
--------------------------------------

Hi Stamatis,  I have a PMR open with IBM and have given them a testcase where they have been
able to recreate the failure, but sporadically; e.g. 1 failure out of 1 or 2 thousand runs.
 You should open a PMR with IBM to pursue this as it seems your symptoms are more consistent
than my own and it might help IBM come up with a fix faster.  So, no, there is no fix as far
as I know at this time. (FP 7.0.0.13 means the WebSphere fix pack level, which IBM publishes
about every 3 months.  With that level is a JDK level, but that level can usually be upgraded/downgraded
separately from WebSphere.  This is an issue with the JDK levels at FP 11 & 13.)

Thanks,
William

> Not sure if this is an Axis2 bug (would have used question category if it was available
to me), but:
> We are invoking the Axis2 1.5.1 org.apache.axis2.wsdl.WSDL2Code tool via an Ant <java>
task and we're seeing sporadic failures where something - e.g. one attribute out of several
is not being included in the generated Stub code, or as below when a method was missing. 
When I say sporadic I'm guessing it's about 5 or 6 identified failures out of hundreds across
our automated nightly Anthill builders and our ClearCase builders.  This is using WSDL 1.1
input.
> I'm only considering the period of time in the last few months when this area of our
tests/builds has been stable and I have no reason to believe these errors are our internal
issues.  Unfortunately, all these builders wipe out the environment after the failure (unless
I take extraordinary action) and so I have only been able to do limited investigation.  I've
never seen the issue in my own development environments.  
> In one of the most recent failures I see our test code failing compilation as below because
it's referencing a class method that WSDL2Code did not generate:
> {quote}
> curam \ util \ test \ webservices \ Axis2WSConnectorTest.java: 268: can not find symbol

> On this same builder another test ran immediately following this failure (same source,
etc.) and did not fail.  The failing build was using the IBM V6 JDK and the non-failing build
was using the Sun V6 JDK.  Based on a google search (only 10 hits found) the above directed
me to this IBM site, which appears to identify xltxe-j as new functionality:

> At this point, with the limited data points I have I feel it's too early to say this
is an Axis2 or an IBM JDK issue, but would appreciate it if anyone has:
> * Further information on these symptoms
> * Thoughts on how I might gather more data when using the Axis2 tool to get for information
so I can pursue with IBM if that's appropriate.
> I admit that I have not yet spent the time pouring over Axis2 and related code, IBM support
site, etc.; but, given our project timelines I needed to get this entered to see if there
is any faspath to resolution.  So, apologies for that.
