Eclipse Import to Web project does not have run on server

Since the previous projects were developed using MyEclipse, it is now time to switch to eclipse. However, the project was imported into eclipse and found that the project was not a Web project and could not be deployed to Tomcat. This problem has been solved now.
First, make sure that eclipse on your machine is a Java EE version, or that you have installed the WTP plugin
Two. Close project first, and then modify the. project file under Eclipse Engineering:
Join in <natures> </natures>
<nature>org.eclipse.wst.common.project.facet.core.nature</nature>
<nature>org.eclipse.wst.common.modulecore.ModuleCoreNature</nature>
<nature>org.eclipse.jem.workbench.JavaEMFNature</nature>
Join in <buildSpec> </buildSpec>
<buildCommand>
<name>org.eclipse.wst.common.project.facet.core.builder</name>
<arguments> </arguments>
</buildCommand>
<buildCommand>
<name>org.eclipse.wst.validation.validationbuilder</name>
<arguments>
</arguments>
</buildCommand>
Three. Open project, and then refresh the project, right-click->properties->project facets->modify Project in projects, select Java and dynamic Web Module
Configure the context Root and content Directory and the source path. For more information, please refer to http://blog.csdn.net/hongchangfirst/article/details/7896283
