Subject CXF Aegis data binding timeout
Date Mon, 02 Nov 2009 21:26:02 GMT

Using CXF 2.1.3, simple front end with Aegis databinding, all configured
through Spring.  When I make rapid-fire SOAP requests from within Eclipse to
test the end-point, from time-to-time I get the following exception:

org.apache.cxf.phase.PhaseInterceptorChain doIntercept

There appears to be a hard limit of 20 seconds timeout in the Aegis databind
step.  Can someone shed light how to increase the timeout or get around of
problem?  In my Google search I have seen indications that upgrade
xmlSchema.jar from 1.4.2 to 1.4.3+ will help.  Does anyone have experience
about it?

Thanks,

Eric
