I was trying out the LifeRay web services to create new user id. With eclipse you can actually generate the client class just by pointing it to the WSDL. And you use this generated class to access its functions. Also find out that by default only localhost can access the web services. To allow others to access you need change one of the properties in portal_ext.properties file. If not you will get error code 403.
liferay, anybody using this?
