为什么Java动态服务器只能在独立的Tomcat上运行但不能在Eclipse上运行

Question

First of all, i don't know if i wrote the question correctly or not.

I have a dynamic web server that I developed on eclipse, and when I run it on eclipse, using Tomcat 8.0.33 i get this

however, if i compiled and build the project and extracted the war file, then put that war file into the work web apps folder into Tomcat installation directory, and then run Tomcat from terminal using startup.sh , it works perfectly, see please

i tried another version of Tomcat, 8.0.24, and the same problem happened.

i am using eclipse Luna Service Release 2 (4.4.2) on mac os El Captine

Update 1

Maybe because I deleted the web content folder and i am putting my files in src/main/webapp

and that is what I do in pom

<plugin>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.4</version>
                <configuration>
                    <warSourceDirectory>WebContent</warSourceDirectory>
                    <failOnMissingWebXml>true</failOnMissingWebXml>
                    <webResources>
                        <resource>
                            <directory>src/main/webapp</directory>
                        </resource>
                    </webResources>
                </configuration>
            </plugin>

Do you think so? if yes how to solve it please ?

If the project is webtools dynamic project, you can edit the file $PROJECT_HOME/.settings/org.eclipse.wst.common.component . Modify the attribute value of source-path of wb-resource element.

<?xml version="1.0" encoding="UTF-8"?>
<project-modules id="moduleCoreId" project-version="1.5.0">
    <wb-module deploy-name="SemanticRecommenderWebservices">
        <wb-resource deploy-path="/" source-path="/src/main/webapp"/>
        <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/java"/>
        <property name="context-root" value="SemanticRecommenderWebservices"/>
        <property name="java-output-path" value="src/main/webapp/WEB-INF/classes"/>
    </wb-module>
</project-modules>
