i am trying to use jax-ws for my web service. i have to invoke a remote method that accepts a java.uitl.List(SecurityAttr is a user defined class) as one of the parameters. i would like guidance in this regard. 1) is it possible to use jax ws for this purpose? if so, how should the complex types and collection classes be serialised? 2) i dint find much guidance or tutorials in this regard. i would be really happy if i could be directed to some documents/samples. 3) as of now i have deployed the server side of the service and i try to connect using a jax rpc client. running wstools from the client, for wsdl to java generation, gives me a class called list along with the SEI and mapping files. i dont know how to use this. i am using the servicefactoryimpl class provided by jbossws to use the jaxrpc-mapping file, but the list class doesnt accept any parameters. hence if i connect from the client and try to pass a List, it doesnt help. Kindly guide me. Any help is much appreciated. Thanks in advance. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4013716#...
