I don't want to eat a big fat man, I just want to make a little progress every day.

<Project xmlns = "http://maven.apache.org/POM/4.0.0" xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi: schemaLocation = "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion> 4.0.0 </modelVersion> <groupId> com. ssh </groupId> <artifactId> mvn-ssh </artifactId> <version> 0.0.1-SNAPSHOT </version> <packaging> war </packaging> <dependencies> <! -- Servlet basics --> <dependency> <groupId> javax. servlet </groupId> <artifactId> servlet-api </artifactId> <version> 3.0-alpha-1 </version> <scope> provided </scope> </dependency> <dependency> <groupId> javax. servlet </groupId> <artifactId> jstl </artifactId> <version> 1.2 </version> </dependency> </dependencies> </project>
