Deploy vaadin 7 war file in EC2

Question:

Tag: amazon-ec2,tomcat7,vaadin,war,vaadin7

I'm trying to deploy a Vaadin 7 example.war file in tomcat 7, using an EC2 server. I upload the file to /var/lib/tomcat7/webapps but then when I go to myIp:8080/example it doesn't find the resource.

Any idea why?

Thanks!


Answer:

Solved!...

To install the manager:

sudo yum install tomcat7-webapps tomcat7-docs-webapp tomcat7-admin-webapps

To solve the Java Version mismatch, org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/prueba2]]:

On Eclipse:

Preferences >> Java >> Installed JREs

On EC2 server:

sudo yum remove java-1.7.0-openjdk
sudo yum install java-1.8.0

Then reinstall Tomcat7 and restart

Thanks @BlunT for all the help!!
