Most of the samples have README files which describe their usage. Many also have batch files (testit.cmd and testit.sh) that will deploy and run the demos for you; these batch files assume your soap server is available at http://localhost:8080. Please see the directory each sample is contained in for the README files and for the "testit" batch files.
If you are new to Apache SOAP please make sure you pass the basic installation tests before attempting to go any further.
If you have any trouble while trying out the samples please see the troubleshooting page.
