sophie commented on CXF-6931:
-----------------------------
What does that mean? Does one of your application already have javax packages
in another version， so it collides with xmlsec.jar? Does cxf official site
give any guideline or other related document? Thx

> This is related to the issue CXF-4603.
> We are having two EARs using xmlsec-1.5.8.
> WS Client works fine for the first time with one of the two applications.
> When we start using the second application we get the following error:
> java.lang.ClassCastException:

> Looks like client is trying to load the DOMXMLSignatureFactory from the JVM

> Can you please provide the steps to get rid of this error?.
> Thank you.
