Open Source Java SOAP Clients

Fronsetia (Free Online Service Testing Application) is a Java web application that allows testing webservices (REST and SOAP). No end-user installations required, just deploy the application on your server and pass the link so that users can use their usual browsers to access Fronsetia. You can think of Fronsetia as a simple version of SoapUI on the web, or a simple and free and open-source version of the "wls_utc" utility. See the project homepage https://fronsetia.sourceforge.io and the project Wiki in the menu above.
