Eclipse Tomcat Add and remove engineering exception

1 after the Eclipse Import project, right-click the server Add and remove project, there is no resource:

Solution: Right-click the project, property-> Select Project facet-> tick Dynamic Web project (note the Web module version, different versions of Tomcat support the Web module differently. )

TOMCAT6 can only use 2.5 or return 2 of the wrong

2 deployment of the project appeared Tomcat version 6.0 only supports EE 1.2, 1.3, 1.4, and Java EE 5 Web modules error; The workaround is as follows:

Under the workspace project, under. Settings, there is a file named Org.eclipse.wst.common.project.facet.core.xml with various version information:

<?xml version= "1.0" encoding= "UTF-8"?>
<faceted-project>
<runtime name= "Apache Tomcat v5.5"/ >
<fixed facet= "Jst.web"/>
<fixed facet= "Jst.java"/>
<installed facet= "Jst.java" version= "5.0"/>
<installed facet= "Jst.web" version= "3.0"/>
<installed facet= "Wst.jsdt.web" version= "1.0"/>
</faceted-project>

Like the above error, you can download Tomcat 7. 0 solution, you can also change the <installed facet= "Jst.web" version= "3.0"/> To lower version version= "2.5"
