if i test my webservice on Sun application Server it says
Method returned
java.util.List : "[net.java.dev.jaxb.array.StringArray@d8615f, net.java.dev.jaxb.array.StringArray@1e0be0d, net.java.dev.jaxb.array.StringArray@1dd55c7, net.java.dev.jaxb.array.StringArray@2a9c92, net.java.dev.jaxb.array.StringArray@18d6483, net.java.dev.jaxb.array.StringArray@1c20eb2, net.java.dev.jaxb.array.StringArray@1530691]"and the soap message it returns is this..

Answer 1

When startting from Java a WebService that has a method that returns
a multi-dimensional array like you have String[][] query(String, String)
maps to slightly different on the client side when importing the wsdl.
For example on the client side the SEI returns an interface to this method as follows:
public List<StringArray> myMethod(String, String)
So on your client you need to use:
List<StringArray> lsa = port.query("metals", "sntlaws");
This is assuming you used wsgen on your WebService Impl in a start-from-Java scenario to create your wsdl's and schema's to your webservice.
