Subject Re:Re: Re: Re: TransactionManager error when invoking multiple instances on two ODE engines
Date Tue, 18 Mar 2014 04:18:46 GMT
Hi Sathwik,

I don't have ode-axis2.properties file in my web-inf folder. I have axis2.xml file instead.
The two axis2.xml files content is like below, which only change their ports from "8080" to
"8180":
