Java Server-side development (II)

It's easier to write an uploaded servlet with eclipse + maven. There is only one place to look. If you do not want to configure the servlet-related jar package in the Pom file, you need to tick Apache Tomcat on the project---Properties->project facets->runtimes tab, to do so, is to add the jar package contained in the Tomcat container to the project's development environment so that the servlet is not reported to be unable to find the jar package error.
