Custom Configurator

[Manuel Darveau]

Hi,

I am trying to write a custom Configurator since my deployment is a bit
special.
I don't want to rely on file system at all. My axis configuration will be
comming from a database and I want to load services programatically. All
service classes will already be in the classpath and the list of service
will be dynamic and controlled by a remote interface.

I created a MemoryAxisServlet  since everything will be deployed in embedded
Jetty:
public class MemoryAxisServlet extends AxisServlet{
  protected ConfigurationContext initConfigContext(ServletConfig config)
throws ServletException {
    ConfigurationContext configContext =
ConfigurationContextFactory.createConfigurationContext(new
MemoryAxisConfigurator());
    configContext.setProperty(Constants.CONTAINER_MANAGED,
Constants.VALUE_TRUE);
    return configContext;
  }
}

public class MemoryAxisConfigurator extends DeploymentEngine{
  public MemoryAxisConfigurator(){
            InputStream in = ...;
            populateAxisConfiguration(in);
  }

  public void engageGlobalModules() throws AxisFault {
      engageModules();
  }

  public AxisConfiguration getAxisConfiguration() throws AxisFault {
    // Load modules from classpath
    loadFromClassPath();
    axisConfig.setConfigurator(this);
    return axisConfig;
  }

  public void setConfigContext(ConfigurationContext configContext) {
    // setting ServletContext into configctx
    configContext.setProperty(HTTPConstants.MC_HTTP_SERVLETCONTEXT,
config.getServletContext());

    // TODO Is this property really needed?
    try {
      Parameter servletConfigParam = new Parameter();
      servletConfigParam.setName(HTTPConstants.HTTP_SERVLETCONFIG);
      servletConfigParam.setValue(config);
      configContext.getAxisConfiguration().addParameter(servletConfigParam);
    } catch (AxisFault axisFault) {
      log.error(axisFault.getMessage(), axisFault);
    }
    super.setConfigContext(configContext);
  }
}

My problem is that I get a:
java.lang.NullPointerException
    at
org.apache.axis2.deployment.DeploymentEngine.loadServices(DeploymentEngine.java:131)
    at
org.apache.axis2.context.ConfigurationContextFactory.createConfigurationContext(ConfigurationContextFactory.java:82)
    at
com.eightd.ftk.webservices.MemoryAxisServlet.initConfigContext(MemoryAxisServlet.java:70)
    ... 15 more

It seems that since I am using loadFromClassPath() in
getAxisConfiguration(), the repoListener variable is not set (in
DeploymentEngine) like it would be when using loadRepository(String
repoDir).
Does "new RepositoryListener(this, true);" in loadFromClassPath() should
simply be replaced by "repoListener = new RepositoryListener(this, true);"?

What about loadServicesFromUrl(), it does not even create a
RepositoryListener.

In the mean time, I can overridein my MemoryConfigurator loadServices() to
do nothing but I am not sure if I will have some side effects.

Thank you!

BTW, if you have a better solution for my context, I would be glad to hear
it!
