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?
