XML-RPC stopped working after update?

[mrothrock]

I just updated to queuemetrics-15.10.6-20 from 15.02 and all my XML-RPC scripts stopped working.  All I did was yum update, nothing else.

I receive this -- Fault Code: 2 Fault Reason: Invalid return payload: enable debugging to examine incoming payload

Debug doesn't really tell me anything:

Any ideas? Thank you

It is almost identical to this old post -- http://forum.queuemetrics.com/index.php?topic=974.0

I also did a wget on my local xmlrpc.do and received the same results as that guy:

[root@x]# wget -O- http://x:8080/queuemetrics/xmlrpc.do

my XML-RPC pages return results as noted in previous note

And a bit of the catalina.log

One last note, if I yum downgrade queuemetrics-15.10.3-1029

Everything works fine again.

[mrothrock]

I fixed the issue after a brief email exchange this morning with support.  It seems that in 15.10.6-20 a file called "xerces.jar" in the WEB-INF/lib was not included anymore.  I copied this file from the older rpm into the new one and XML-RPC works again as expected.
