integration-test with web server

I want created a integration-test with web server tomcat to launch integration test execute

mvn integration-test -Ptomcat 

to generate war file

mvn package

In a hand i have web server tomcat: to launch integration-test i have a this file pom.xml to start and stop tomcat web service

   tomcat
   
 
      org.codehaus.mojo
      tomcat-maven-plugin
      1.1
      
       true
       true
       /${project.build.finalName}
       ${project.build.directory}/${project.build.finalName}.war
       9876
      
      
       
        start-tomcat
        pre-integration-test
        
         run-war
        
       
       
        stop-tomcat
        post-integration-test
        
         shutdown
        
       
      
     

and the other hand i have the integration test

   
    maven-surefire-plugin
    
     true
    
   
   
    maven-failsafe-plugin
    2.7.2
    
     
      **/*Test.java
     
    
    
     
      integration-test
      integration-test
      
       integration-test
      
     
     
      verify
      verify
      
       verify
      
     
    
   
  

But I have a problem to add resources files. you need add this line in your pom.xml file

     
      src/test/resources
      
       app.properties
      
     
    

and add this line in pom.xml file to erase previous resources files generate with execute integration test

      org.apache.maven.plugins
      maven-clean-plugin
      2.5
      
       
        clean
        generate-resources
        
         clean

Make inference with pellet in Virtuoso

  set = new VirtGraph(GraphIri, "jdbc:virtuoso://" + uriServer + ":"
    + portJDBC + "", db_user, db_pass);
  vd = new VirtDataSource("jdbc:virtuoso://" + uriServer + ":" + portJDBC
    + "", db_user, db_pass);
  System.out.println("Start inference!");
  Reasoner reasoner = PelletReasonerFactory.theInstance().create();
  reasoner = reasoner.bindSchema(set);
  infModel = ModelFactory.createInfModel(reasoner, modelVirtuoso);
  System.out.println("Stop inference!");
  Model m2 = vd.getNamedModel(GraphIri);
  Model inferido = infModel.difference(m2);
  m2.add(inferido);
