Today, a Javaweb project was established using Eclipse+maven and the Web container JBoss EAP 6.2 was configured in Eclipse. Create a new JSP page and add a simple Java class. However, a "red" error message appears at the top of the JSP page: the superclass "Javax.servlet.http.HttpServlet" was notfound on the Java Build Path. The original Javaweb project class did not add the Web container runtime related classes caused.

Error message:

The workaround is simple, add the following configuration to the Pom.xml:

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

Add: If you are also prompted for an error, you can also try the following:

1. Right-click Web Project-"Properties or Build path-" Java build path->libraries-> Add libray...->server Runtime-"JBoss 7.1 runtime

2. Switch to Orader and Export in the Java Build path interface, select
