ERROR!! SAXParseException: Premature end of file.

[Harathi Rao]

I get the error

org.xml.sax.SAXParseException: Premature end of file.

when i try to retrive the results which returns a List from my service method at clent side.

public class TestService{
 
public static void main(String argv[]) throws RemoteException,ServiceException{

UsersServiceLocator serviceLocator = new UsersServiceLocator();
UsersService usersService = serviceLocator.getUsersService();
Object[] usersList = usersService.getUsers(10);
System.out.println(usersList); 
}
}

where the getUsers() returns a List


In the tomcat console i get

 
22:54:48,812 ERROR Message:530 - java.io.IOException:
AxisFault
 faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
 faultSubcode:
 faultString: java.io.IOException: No serializer found for class Contact in registry org.apache.axis.encoding.TypeMappingDelegate@1f6321  

where is the problem? Any kind os help !!

Thanks in advance,

Axis can't just serialize an object it doesn't know (like Contact). You need to provide a serializer/deserializer - have you done that? If yes, then it would seem that it isn't registered properly.
If you don't have one, look into whether you can use the built-in BeanSerializer. It can serialize objects that adhere to the Java Bean pattern.

hi thanks for the reply,
but the class Contact is returning a List in this fashion

public class TestService{
 
public static void main(String argv[]) throws RemoteException,ServiceException{
               
UsersServiceLocator serviceLocator = new UsersServiceLocator();
UsersService usersService = serviceLocator.getUsersService();
Object[] usersList = usersService.getUsers(10);// this returns a List
System.out.println(usersList); 
}
}
 

getUsers() returns a List

public List getUsers(int orgId) {
 
 Users users = new UsersList();      
 
 Contact c=new Contact ();
 
        c.setUsersList(users.getUsersByOrgId(orgId));
 
        return c.getUsersList(); // returns List
 
     }
 

Is the List object not recognised by Axis?

[Ulf Dittmer]

The error message says that it is trying to serialize the Contact class, so you might want to check your code if you are specifying that somewhere.

Looking at the two code snippets, it seems that the server sends a list, while the client seems to expect an array, so there's a problem right there. You can consult this article on how to serialize collections (basically, since List is unknown to SOAP, as arrays).

I was able to solve the problem when i tried to wrap the List in to a bean and have a bean mapping in the wsdd. which goes like this...

   <beanMapping qname="ns:Contact"    
    xmlns:ns="http://model.mycomp.net"
    languageSpecificType="java:net.mycomp.model.Contact"  />

Thanks for the article it was very useful to me.

Could you please to tell us, where did you put the snip code above exactly???
