ok, updated based on comments, changed scope compile seems pass issue of class not found!

<dependency> <groupid>javax.servlet</groupid> <artifactid>javax.servlet-api</artifactid> <version>3.1.0</version> <scope>compile</scope> </dependency>

class not found @ runtime available @ compile time. need add together corresponding jar can found @ runtime. utilize ivy , in eclipse

project -> properties ->deployment assembly -> add together -> java build path enteries -> ivy -> finish

there must similar maven well.

also need javax.servlet-api during compile time container using run server provide actual apis @ runtime.

java spring junit
