    java-wsdl conversion for Custom Exception

    Aarti S Newbie

      Below is the scaled down version of a service that i am trying to develop. My service throws a custom exception. However, i get an error when trying to generate a WSDL for this SEI.

      SEI

      package com.testservice;
      
      import java.rmi.Remote;
      import java.rmi.RemoteException;
      
      import com.testservice.exception.MyCustomException;
      
      public interface ExceptionService extends Remote
      {
       public void throwCustomException() throws MyCustomException, RemoteException;
      }
      



      MyCustomException class

      package com.testservice.exception;
      
      public class MyCustomException extends Exception
      {
       private int errorCode;
      
       private String customMsg;
      
       private String[] arr;
      
       public MyCustomException()
       {
       super();
       }
      
       public MyCustomException(int errorCode, String customMsg, String[] arr) {
       super();
      
       this.errorCode = errorCode;
       this.customMsg = customMsg;
       this.arr = arr;
       }
      
       public String[] getArr() {
       return arr;
       }
      
       public void setArr(String[] arr) {
       this.arr = arr;
       }
      
       public String getCustomMsg() {
       return customMsg;
       }
      
       public void setCustomMsg(String customMsg) {
       this.customMsg = customMsg;
       }
      
       public int getErrorCode() {
       return errorCode;
       }
      
       public void setErrorCode(int errorCode) {
       this.errorCode = errorCode;
       }
      
      }
      



      ANT for generating stubs

       <target name="generate_stubs" depends="prepare">
       <taskdef name="wstools" classname="org.jboss.ws.tools.ant.wstools">
       <classpath refid="client.path"/>
       </taskdef>
       <wstools dest="${configs.dir}" config="${basedir}/wstools-config.xml"/>
       </target>
      



      WSTools Config XML

      <configuration xmlns="http://www.jboss.org/jbossws-tools">
       <java-wsdl>
       <service name="ExceptionService" style="rpc" endpoint="com.testservice.ExceptionService"/>
       <namespaces target-namespace="http://com.testservice" type-namespace="http://com.testservice/types"/>
       <mapping file="jaxrpc-mapping.xml"/>
       <webservices servlet-link="ExceptionService"/>
       </java-wsdl>
      </configuration>
      



      And the error i get on running the ANT is ...
      generate_stubs:

      (I have a JBoss-4.0.4 setup running on Java5)

      I can solve this problem if i change the order of parameters to parameterized constructor of MyCustomException as follows:
       public MyCustomException(String[] arr, String customMsg, int errorCode) {
       super();
      
       this.errorCode = errorCode;
       this.customMsg = customMsg;
       this.arr = arr;
       }
      


      I would like to know
      1) Is this an expected behavior or bug?
      2) If it is an expected behavior, are there any guidelines for the order in which parameters to a parameterized constructor are passed?
