Axis error: java.lang.reflect.InvocationTargetException

Question

Hello!
I have seen this question, asked many times, but I couldn't find any suitable solution for my problem. I am deploying a web service with Apache Tomcat 5.5.27 and Axis 1.4
When I make a call to the service in this way:
try{
               call.setTargetEndpointAddress(new URL(endpoint));
               }catch(Throwable e)
                    System.out.println("ERROR: " + e.getMessage() + " CAUSE: " + e.getCause());
                    e.printStackTrace();
                    return;
               call.setOperationName(new QName("bookTicket"));
               call.addParameter("flightIDs",XMLType.SOAP_ARRAY, ParameterMode.IN);
               call.setReturnType(XMLType.XSD_STRING);
               String reservationID = null;
               try{
                    reservationID = (String)call.invoke(new Object[] {params});
               }catch(Throwable e)
                    System.out.println("ERROR: " + e.getMessage() + " CAUSE: " + e.getCause());
                    e.printStackTrace();
                    return;
               }I get the following error:

     at client.AirplaneServiceClient.main(AirplaneServiceClient.java:113)The signature of the method I am calling looks like this:
public String bookTicket(String [] flightIDs) My CLASSPATH is set corectly and all the jars are in the right places (or at least most of them), because when I call any other method of my service, it works.
If anyone has encountered the same problem, any help would be appreciated.
I have tried to look in tomcat logs, but I didn't find anything relevant.
Thanks and looking forward for some answers.
