servletcontext.addservlet non è definito

Sto tentando di avviare manualmente il dispatcherservlet come esercizio. Il codice èservletcontext.addservlet non è definito

ServletRegistration.Dynamic dispatcher = container.addServlet("appServlet", new DispatcherServlet(appContext));

sto usando javax.servlet-api-3.0.1 (che ha addServlet), ma sto ottenendo un errore non definito metodo. Tuttavia, quando uso il codice completo, viene visualizzato il metodo addServlet, anche se eclissi IDE mi dice che il metodo non è definito per il tipo ServletContext. Uso anche eclipse juno con glassfish. Immagino di avere una sorta di conflitto di vasi - ma dove? L'errore piena quando si tenta di eseguire è la seguente:

java.lang.Exception: java.lang.IllegalStateException: ContainerBase.addChild: start:  org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException: java.lang.Error: Unresolved compilation problem:

Non del tutto sicuro perché questo sta accadendo, possibili conflitti? Comunque il mio pom è sotto, forse qualcun altro vede qualcosa?

Verificare quali altre librerie che avete sul vostro percorso di generazione. È possibile che uno di essi abbia una versione diversa di Javax.Servlet. Se non riesci a rimuovere il vaso aggiuntivo, prova a modificare l'ordine in cui sono caricate le librerie.

Ho affrontato lo stesso problema e poi trovato la versione precedente di servlet-api.jar nel mio percorso di classe, di risolvere il problema ho rimosso il file e ha aggiunto versione più recente del file da apache-tomcat-7.0.59 \ lib

Ehi ragazzi mi è stato anche affrontando lo stesso problema, ma ho trovato la soluzione:

stavo usando primavera 4.0.4 come la dipendenza e la mia servlet dipendenza stavo

 <dependency> 
      <groupId>javax.servlet</groupId> 
      <artifactId>servlet-api</artifactId> 
      <version>2.5</version> 
      <scope>provided</scope> 
     </dependency>

Questa dipendenza servlet non è compatibile con la molla 4.x. Per renderlo compatibile l'ho cambiato:

 <dependency> 
      <groupId>javax.servlet</groupId> 
      <artifactId>servlet-api</artifactId> 
      <version>3.1.0</version> 
      <scope>provided</scope> 
     </dependency>

Ora funziona. Spero che questo ti possa aiutare!

l'artefatto corretta è:
