NullPointerException with code generated from PayPal wsdl
---------------------------------------------------------
Key: XFIRE-915
URL: http://jira.codehaus.org/browse/XFIRE-915
Project: XFire
Issue Type: Bug
Components: Aegis Module
Affects Versions: 1.2.4
Environment: Linux/Gentoo, Java 1.6, eclipse 3.2
Reporter: Lado Kumsiashvili
Assigned To: Dan Diephouse
Attachments: generated.jar
I'd lige to use xFire FW for making PayPal SOAP API calls. So i've generated
Java classes from PayPal wsdl and i have wroten a small test class, that uses
this classes.
hier are links to PayPal wsdl and belonging XML Schemas:
PayPal Schema tps://www.sandbox.paypal.com/wsdl/PayPalSvc.wsdl
eBL Base Components https://www.sandbox.paypal.com/wsdl/eBLBaseComponents.xsd
Component Types
https://www.sandbox.paypal.com/wsdl/CoreComponentTypes.xsd
I use in my client(see code below) some dummy params. They do not really
matter. So i must receive some erros(Incorrect params, etc) as replay.
I have used debugger, and i receive a soap response, but then an
NullPointerException occures. So a can not read any errors or transaction
details in my programm.
.....
The code(I ve generated java classes with eclipse plugin and choose package
name jira.xfire. If you choose another package name, please change this name on
the test program too.
package jira.xfire;
import java.util.List;
import javax.xml.ws.Holder;
import xfire.jira.PayPalAPIInterface;
import xfire.jira.PayPalAPIInterfaceServiceClient;
import ebay.api.paypalapi.GetTransactionDetailsReq;

import ebay.api.paypalapi.GetTransactionDetailsResponseType;
import ebay.apis.eblbasecomponents.CustomSecurityHeaderType;
import ebay.apis.eblbasecomponents.ErrorType;
import ebay.apis.eblbasecomponents.UserIdPasswordType;
/**

public class Main {
/**

public static void main(String[] args) {
GetTransactionDetailsRequestType r = new
GetTransactionDetailsRequestType();
r.setVersion("1.0");
r.setTransactionID("87K78012VR671152J");// some dummy value
PayPalAPIInterfaceServiceClient cc = new
PayPalAPIInterfaceServiceClient();
PayPalAPIInterface api = cc.getPayPalAPI();
GetTransactionDetailsReq request = new GetTransactionDetailsReq();
request.setGetTransactionDetailsRequest(r);
CustomSecurityHeaderType requesterCredentials = new
CustomSecurityHeaderType();
UserIdPasswordType auth = new UserIdPasswordType();
auth.setUsername("sdk-seller_api1.sdk.com");// We use some dummy
// user and password.
// But response must
// come
auth.setPassword("12345678"); // and contain errors
requesterCredentials.setCredentials(auth);
Holder<CustomSecurityHeaderType> a2 = new
Holder<CustomSecurityHeaderType>();
a2.value = requesterCredentials;
// call
GetTransactionDetailsResponseType response = api.getTransactionDetails(
request, requesterCredentials, a2);
List<ErrorType> errors = response.getErrors();
if (errors != null && errors.size() > 0) {
System.out.println("\nERROR");
for (ErrorType error : errors) {
System.out.println("\nErrorCode: " + error.getErrorCode());
System.out.println("\nShortErrorMessage: "
+ error.getShortMessage());
System.out.println("\nLongErrorMessage: "
+ error.getLongMessage());
}
} else {
System.out.println(response.getPaymentTransactionDetails()
.getPayerInfo());// some dummy code
}
}
}
and the Stacktrace:

The problem occures beacuse in the Method public static Type
getReadType(XMLStreamReader xsr, MessageContext context, Type type, TypeMapping
tm)
null as type is passed. an then on the line 186 the code tries to read some
member of type(null)
i've fixed this problem temporary with replaceing line 186 code
if (!overrideTypeName.equals(type.getSchemaType())) with if ( type!= null &&
!overrideTypeName.equals(type.getSchemaType()))
but i do not know if this solussion is good.
P.S.
I habe also atteched the all the generated code incl. my test Program Main.java
So long,
Lado
