Invoking ALDSP 3.0 Services using Axis

Question

Hi All,
I have exposed some services using ALDSP 3 studio which returns multiple records. These are the steps I followed:
1) Created a Physical Data Service using Relational DB (Oracle 9i). Imported some tables like CUSTOMERS, ORDERS etc.
2) Then opened ORDERS.ds and added a new Operation called getAllOrders() which returns all the orders in the DB.
3) I created a Web Service Map and tested the webservice in ALDSP. It works fine.
4) I created a WSDL out of it and then If I try to access it from Axis Web Service Client as shown below... It blows up with the exception
URL url = new URL("http://10.142.29.3:8001/RetrieveOrderProject/ALDSPWebService/DSP-INF/Logical/OrderDataService.ws");
OrderDataServiceSoapServiceLocator locator = new OrderDataServiceSoapServiceLocator();
OrderDataServicePT order = locator.getOrderDataServiceSoapPort(url);
DSP_INF._MSL_ORDER[] orderArr = order.getAllOrders();
At this point it throws:
AxisFault
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: java.lang.ArrayStoreException: [LDSP_INF._MSL_ORDER;

Any help in this regard is appreciated.

Thanks mreiche,
I have created a logical service with 3 operations and all the 3 operations returns array. The return type in ALDSP is of type SF_CUSOTMERS. This schema is generated by ALDSP for a table SF_CUSTOMERS. When I test this in ALDSP, all the 3 services gives me around 4 to 5 records.
However when I try to access this using axis, it fails.
One more strange thing is the WSDL generated from ALDSP has some bugs in it when I try to validate the WSDL in ALDSP studio. I will send you the WSDL to your personal mail ID. Can you please guide me further and help me in this.
Thanks,
Ram
