Deploy JSP Webapplication on Tomcat7 (via OpenShift with GIT)

Question

I have build a web appliation containing a Spring MVC project with a mysql database and a tomcat7 server. This is now published to GIT of OpenShift. But starting the server takes only 160ms and I can clearly see nothing is being loaded really.

How do I do a real deployment and connect the Openshift Tomcat to my project? I can code, but deployment-wise I am not a smart bulb.

My GIT repository looks like this:

What is wrong?

EDIT: As requested the pom.xml:

Answer 1

It seems that you have forgotten to add an openshift maven profile inside your pom.xml like bellow with proper maven-war-plugin configuration.

<profiles>
    <profile>
        <id>openshift</id>
        <build>
            <finalName>travel</finalName>
            <plugins>
                <plugin>
                    <artifactId>maven-war-plugin</artifactId>
                    <version>2.1.1</version>
                    <configuration>
                        <outputDirectory>webapps</outputDirectory>
                        <warName>ROOT</warName>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

Then your application structure seems unusual. Usually to build a WAR with maven you put your webapp content in src/main/webapp, your resources in src/main/resources your WAR specific classes in src/main/java.

Take a look at maven-war-plugin user guide here.

Finally, check these documentations that could help you to unterstand how to deploy your application to Tomcat with OpenShift:

• Host and Run Your Java Tomcat Application for Free on OpenShift’s PaaS
• Tomcat Application Hosting

If you follow properly steps described in these documentations, then any git push will trigger a build and application re-deployment to Tomcat

EDIT As you have a build compilation issue now (Java 8 not supported), you should take a look at this answer: invalid target release 1.8
