[jboss-jira] [JBoss JIRA] (WFLY-3262) WebServiceRef injection without explicit wsdl file fails during Servlet initialization

[R Searls (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-3262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13014654#comment-13014654 ] 

R Searls commented on WFLY-3262:
--------------------------------

The fundamental problem is that a servlet object is created for ServletLoadOnStartup
and EJB3Bean.  ServletLoadOnStartup is dependent on (servlet) EJB3Bean. ServletLoadOnStartup is defined explicitly by the user.  EJB3Bean is defined by WildFly as class org.jboss.wsf.spi.deployment.WSFServlet.  The user explicitly sets annotation @WebServlet attributes. WildFly class org.jboss.wsf.spi.deployment.WSFServlet does not use annotation @WebServlet, nor set related attributes.  The setting of ServletLoadOnStartup's WebServlet attribute loadOnStartup = 1 causes  this class to be started before the EJB3Bean servlet, hence this failure.

It is unclear if intelligence needs to be added to WildFly to detect this dependency 
relationship and set WSFServlet attributes in accordance with the (parent) or to document this as expected behavior.

> {code}
> If I change loadOnStartup parameter to -1, everything works fine, i.e. servlet gets instantiated and WS is injected correctly. Therefore, I suppose this is a bug.
> Another workaround exists - adding wsdl file to the deployment archive and using the 'wsdlLocation' parameter in @WebServiceRef (as can be seen in ServiceRefSevletTestCase).
