Hi All,

I am programing on using the java script ot access web service. I follow the example of Amazon(http://www.mozilla.org/projects/webservices/examples/mozilla-wsdl/index.html), but have problem on interface which return ComplexType - the call back function cannot be called. I compare the wsdl of Amazon sample and mine, found in the part of defining complex type, amazon sample uses the <xsd:all> to enclose the element, but mine use the <sequence> tag. (My wsdl was generated by Apache Axis automatically from java class.) Then I changed my wsdl, replace the sequence with the xsd:all. And the callback can be called. But problem is the return value has error(ns_error_failure). Even when I call a interface which only return int, the return value is always 0. ( I check the log of server, the server call was made, but return value was wrong)

I tested this problem for nearly one week, but can not solve it. Can anyone kindly help me? Thanks in advance.

My js code is here: function getAMark () // test by the way amazon uses {

//var aValue = "chinese";

    if (!proxy) {
       var listener = {

         // gets called once the proxy has been instantiated
         onLoad: function (aProxy)
         {
           proxy = aProxy;
           proxy.setListener(listener);
           requestBookmarks(1);
         },

         // gets called if an error occurs
         onError: function (aError)
         {
           alert(aError);
         },

         // callback function is hardcoded to {methodname}Callback in 

1.4beta

         testCallback : function (aresult)
         {
         alert("enter callback, result="+aresult);
         alert("a="+aresult.a+", b="+aresult.b);
         }
       };
       createProxy(listener);
     }
     else {
       requestBookmarks(1);
     }

}

  function createProxy(aCreationListener)
   {
     try {
       var factory = new WebServiceProxyFactory();
     factory.createProxyAsync('http://localhost:8080/coreWeb/wsdl/Test2.wsdl', "Test2", "", true, aCreationListener);
     }
     catch (ex) {
       alert("test "+ ex);
     }
   }

  function requestBookmarks(vp)
   {
     if (proxy) {
       netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");

     proxy.test();

      alert("call complete!");
     }
     else {
       alert("Error: Proxy set up not complete!");
     }
   }
