java-wsdl conversion for Custom Exception
rt_s Jul 13, 2006 5:11 AMBelow 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 ...

(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?
