      Description

      Conditions for the error to occur:

      • use of the scripting module (ie. add "axis2-scripting-*.mar" to your modules/modules.list)
      • use of the "axis2.xml.url" web.xml parameter or packaging of the webapp into a WAR/EAR

      The problem is that during the initialization of the scripting module (ie. the call to org.apache.axis2.scripting.ScriptModule.init()) it checks for the repository in the axisconfiguration to be not null.
      The relevant code is:
      AxisConfiguration axisConfig = configContext.getAxisConfiguration();
      if (axisConfig.getRepository() == null)

      { log.error("AxisConfiguration getRepository returns null, cannot deploy scripts"); }

      else

      { ... // scripting module initialization }

      If ConfigurationContext.getAxisConfiguration().getRepository() returns null, then the scripting module logs an error and the module is not initialized.

      Now the problem causing this to happen is in org.apache.axis2.deployment.DeploymentEngine.loadRepositoryFromURL().
      The exact callstack will look like this (without line numbers, because I don't want to get version-specific):

      • DeploymentEngine.loadRepositoryFromURL(URL repoURL)
      • WarBasedAxisConfigurator.getAxisConfiguration()
      • ConfigurationContextFactory.createConfigurationContext(AxisConfigurator axisConfigurator)
      • AxisServlet.initConfigContext(ServletConfig config)
      • AxisServlet.init(ServletConfig config)

      If you take a look at WarBasedAxisConfigurator.getAxisConfiguration(), you'll see that depeding on the configuration it executes one of the following to load the repository:

      • DeploymentEngine.loadRepository(String repoDir)
      • DeploymentEngine.loadRepositoryFromURL(URL repoURL)
      • DeploymentEngine.loadFromClassPath()

      In case of loadRepository(String repoDir) there's a call to "axisConfig.setRepository(axisRepo.toURL())" which sets the repository reference in the axis configuration.
      In case of loadRepositoryFromURL(URL repoURL) there's no such call, which results in ScriptModule.init() in the error message I described earlier.

      The fix is easy: in org.apache.axis2.deployment.DeploymentEngine.loadRepositoryFromURL(URL repoURL) put a axisConfig.setRepository(repoURL) call before the axisConfig.validateSystemPredefinedPhases() call.

      As for DeploymentEngine.loadFromClassPath(), I don't know how to set the repository URL.
      Any idea? Or any other way to use the scripting module without an axis2.xml?
      My guess is that ScriptModule should be modified to handle the case, when repository is loaded from CLASSPATH. Ie. it should try to pick up the scriptServicesDirectory from the CLASSPATH as well.
      Currently it's hard-coded to look for the scriptServicesDirectory within a filesystem entry pointed to by a File object.

      P.S.: this bug is present in v1.4.1, v1.5.3 and in SVN trunk (at the moment of writing). I guess this has been around from the beginning.
