Java Soap test request against our Php soap server

Hi,
we need a java application making a test call to our soap server with a list of configurations provided by you covering as many as possible all the options the protocol.
We give a soap wsdl and a curl test call to replicate.
Our server is working against php soap client, curl and soapUi but it fails against our customer java client for larger messages, so we need it to investigate the problem.
