}

@Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
      return builder.sources(DemoApplication.class);
   }

}

while deploying the application to the weblogic server, getting the below exceptions

Just add this dependancy ` javax.servlet javax.servlet-api 3.1.0 provided `. It is only needed at compile time, it will be provided runtime by the server container. So, that's why `provided` is added to pom dependency. — harshavmb, Jun 18 '17 at 14:28
@harshavmb getting the class not found exeception during the deployment of the application could u please help ? update the question with the exeception — user1245524, Jun 18 '17 at 14:42
Yeah. I understand. The original issue has been fixed. I need more details from your end. Have you exploded war and checked if you have all the dependencies. I suspect tomcat is also bundled into war which is why having the issue. — harshavmb, Jun 18 '17 at 15:10
please tell me what details you need, I don't know how to check the exploded war — user1245524, Jun 18 '17 at 15:16

@harshavmb the build issues got resolved , but other execeptions are coming — user1245524, Jun 20 '17 at 06:30

@harshavmb when I access the deployed war file its accessing credentials, and if i keyin the weblogic credentials its not accepting — user1245524, Jun 20 '17 at 07:57
@harshavmb all the issues got resolved I could see the index.html — user1245524, Jun 20 '17 at 09:37

Just add this dependency to your pom

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

It is only needed at compile time, it will be provided runtime by the server container. So <scope>provided</scope> is added to pom dependency.

Refer this link for more details.

Hope this helps!

This dependency is required because you are extending the SpringBootServletInitializer class :

@SpringBootApplication
public class DemoApplication  extends SpringBootServletInitializer {
  // ...
}

If you remove it, the build will succeed.

Otherwise, you need to add the javax.servlet-api dependency.
