Davanum Srinivas resolved AXIS2-2484.
-------------------------------------
Resolution: Fixed
> IllegalArgumentException: Null InputStream is not a valid argument when
> loading axis client from URLClassLoader
> ---------------------------------------------------------------------------------------------------------------
>
> Key: AXIS2-2484
> URL: https://issues.apache.org/jira/browse/AXIS2-2484
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: kernel
> Affects Versions: 1.1.1
> Environment: Sun JDK 1.4.2, Axis 1.1.1, Windows 2000, ADB data binding
> Reporter: Jacques Desmazieres
>
> I have a application with a plugin feature. I have implemented an Axis 2
> service and generated both service and client using java2wsdl and wsdl2java.
> When invoking the service using the generated client, loaded in the
> classpath, everything is ok.
> But when I load the client in an URLClassloader, with all the Axis2 libraries
> specified in the url[] parameter, I have the following message:
> java.lang.IllegalArgumentException: Null InputStream is not a valid argument
> at
> com.ctc.wstx.stax.WstxInputFactory.createSR(WstxInputFactory.java:602)
> at

> at
> org.apache.axis2.deployment.FileSystemConfigurator.getAxisConfiguration(FileSystemConfigurator.java:109)
> After some investigation, it appears that the exception is raised beacause
> the FileSystemConfigurator class cannot find the default axis2.xml
> configuration file.
> I have found that the issue comes from the loading of the default axis2.xml
> config file in the org.apache.axis2.deployment.getAxisConfiguration() method
> line 106:
> ClassLoader cl = Thread.currentThread().getContextClassLoader();
> In my case, the classloader retrieved is the one of the calling application
> (not the plugin's classloader) and so the axis2 (and mainly
> axis2-kernel-1.1.1.jar) is not found.
> Why retrieving the context classloader ? Is there a reason for that ? Can I
> fix that with a proper configuration ? Deploying the axis2 kernel jar at
> application level is not an option.
> If you replace the source code line by the following fixes the problem:
> ClassLoader cl = getClass().getClassLoader();
> As we retrieve the service client's classloader, Axis is able to find the
> default configuration file.
