4:11 a.m.
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:
| [wstools] log4j:WARN No appenders could be found for logger

| [wstools] log4j:WARN Please initialize the log4j system properly.

(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?
