Servlet isn't loaded at startup

Question

I am trying to initial some classes via a SIP-servlet. For that I am using a sip.xml for my mss-2.0.0.FINAL-jboss-as-7.1.2 server.

Sip.xml:

<?xml version="1.0" encoding="UTF-8"?>  
    <sip-app xmlns="http://www.jcp.org/xml/ns/sipservlet" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
      xsi:schemaLocation="http://www.jcp.org/xml/ns/sipservlet" xmlns:javaee="http://java.sun.com/xml/ns/javaee"  
      xmlns:xs="http://www.w3.org/2001/XMLSchema" version="1.1">  


      <app-name>service.ngsi.multimediaconference</app-name>  


      <servlet-selection>  
      <servlet-mapping>  
      <servlet-name>multimedia-conference</servlet-name>  
      <pattern>  
      <equal>  
      <var>request.method</var>  
      <value>INVITE</value>  
      </equal>  
      </pattern>  
      </servlet-mapping>  
      </servlet-selection>  


      <servlet>  
      <servlet-name>multimedia-conference</servlet-name>  
      <servlet-class>com.abc.multimediaconference.ServletSipMultimediaConference</servlet-class>  
      <load-on-startup>1</load-on-startup>  
      </servlet>  


      <session-config>  
      <session-timeout>120</session-timeout>  
      </session-config>  
    </sip-app>

After that my module can be used and also the REST communication works but all variables/ object which should be initial via servlet on startup are null.

Someone an idea?

Answer 1

The SipServlet primary initialize some objects.

ServletSipMultimediaConfrence.java:

    @javax.servlet.sip.annotation.SipServlet
public class ServletSipMultimediaConference extends SipServlet {
    ...
    @Override
    public void init(ServletConfig config) throws ServletException {
        super.init(config);
        ctx = config.getServletContext();

        System.out.println("Init SIP Servlet!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");

        SipFactory sipFactory = (SipFactory) getServletContext().getAttribute(
                SipServlet.SIP_FACTORY);
        if (sipFactory == null) {
            getServletContext().log("SIP Factory is null");
        } else {
            getServletContext().log("SIP Factory set.");
        }
        ContextManager.getInstance().setSipFactory(sipFactory);

        getServletContext().log("SipServlet MultimediaConference initialized.");

        configureThirdPartyCallModule();
    }
...
}

If I try to invite a participant to a conference I got a NullPointerException cause my SipFactory is null!

MultimediaConferenceImpl.java:

@POST
@Path("/inviteParticipant")
@Override
public void inviteParticipant(@QueryParam("sessionId") String sessionId,
        @QueryParam("callSessionIdentifier") String callSessionIdentifier,
        @QueryParam("participant") String participant) throws PolicyException,
        ServiceException {

    CallSessionConference conferenceSession = getConferenceSession(null,
            callSessionIdentifier);
    if (conferenceSession == null)
        throw new ServiceException("No conference found using id: "
                + callSessionIdentifier);

    conferenceSession.inviteParticipant(participant);
}

This leads to following exception:

This happens cause my SipFactory is null when Call.java try to get it from servlet-context.

static {
        factory = ContextManager.getInstance().getSipFactory();
    }

ContextManager is a helper class:

public class ContextManager {

    private SipFactory factory;
//  private BundleContext bundleContext;

    private static ContextManager cm = new ContextManager();

    public static ContextManager getInstance() {
        return cm;
    }

    public SipFactory getSipFactory() {
        return factory;
    }

    public void setSipFactory(SipFactory factory) {
        this.factory = factory;
    }
}

My full log on DEBUG level here: https://community.jboss.org/thread/232864

You say the problem is that SipFactory is null. But the code you posted never initializes the SipFactory. Look at ServletSipMultimediaConference.init() method. You just check if the SipFactory is null, but you do not initialize it:

public class ServletSipMultimediaConference extends SipServlet {
...
@Override
public void init(ServletConfig config) throws ServletException {
    ...
    SipFactory sipFactory = (SipFactory)getServletContext()
        .getAttribute(SipServlet.SIP_FACTORY);
    if (sipFactory == null) {
        getServletContext().log("SIP Factory is null");
        //  -->  Maybe set up a new SIP Factory here?!  <--
    } else {
        getServletContext().log("SIP Factory set.");
    }
    ContextManager.getInstance().setSipFactory(sipFactory);
    ...
}
}

Can you provide DEBUG logs for org.mobicents category as well ? It seems your init method is not even called.

I see that the SIP Servlet is defined both in sip.xml and as an annotation, the annotation may take precedence here did you try to add loadOnStartup=1 to the @javax.servlet.sip.annotation.SipServlet annotation ?

the init method logging statement should be displayed in the logs on startup when the application is deployed

I found the problem. It was a maven/ a pom.xml failure! I forget to put into my maven plugin-config following entry: <warSourceDirectory>WebContent</warSourceDirectory>

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <warSourceDirectory>WebContent</warSourceDirectory>
        <failOnMissingWebXml>false</failOnMissingWebXml>
    </configuration>
</plugin>
