Thanks for the reply but I tried changing the property as you suggested and it made no difference. I searched through the source code and the only reference to anything that included acquireTransactionLocks as a property is in ode-trunk\axis2-war\src\test\webapp\WEB-INF\conf.hib-derby\ode-axis2.properties. I don't know if that's even valid.
