Class loading issue when deploying Axis1 services
-------------------------------------------------
Key: WSAS-802
URL: https://wso2.org/jira/browse/WSAS-802
Project: WSO2 WSAS
Issue Type: Bug
Components: axis1-deployer
Affects Versions: 2.3
Environment: winxp, jdk5
Reporter: Charitha Kankanamge
Assignee: Sameera Jayasoma
Priority: Highest
Attachments: SimpleMath.jar, SimpleMath.wsdd, SimpleMathResource.jar
I encountered the following class loading issue when deploying an Axis1 service
with dependencies.
I have a class called com.test.SimpleMath and it has a dependent class in the
package org.charitha.
i.e:-
package com.test;
import org.charitha.Area;
public class SimpleMath {
----
----
}
Then I used the SimpleMath class as service implemetation class in my wsdd as
follows.
<parameter name="className" value="com.test.SimpleMath"/>
Then I uploaded these 3 artifacts (*.wsdd, SimpleMath.jar and dependancy jar)
through WSAS management console.
Service deployed as faulty with the following exception.

I noticed that the service implementation class was replaced by the dependent
class after uploading the artifacts from WSAS management console. In other
words, org.charitha.Area (which was my dependency in this example) class has
been added to SimpleMath.jar instead of com.test.SimpleMath class.
This issue did not occur when I copied the dependency jar to WSAS_HOME/lib
directory. Therefore, something is wrong with the Axis1 service uploading
mechanism.
The relevant artifacts are attached here with.
