java - INFO: No Spring WebApplicationInitializer types detected on classpath

Question

I have a spring project that runs fine on my tomcat7 server when I deploy from eclipse: Run As >> Run on server. In the eclipse tab "Servers" I see:

Servers
 Tomcat v7.0 Server at localhost [Started, Synchronized]
   my_project [Synchronized]
     spring-web-3.2.4-RELEASE.jar

My project:

• does not use web.xml, I use javaconf @ annotations.
• does not use maven, I use a User Library

I see that the project is in:

/srv/applications/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0

And, I also see the folders: conf,logs,temp,webapps,work,wtpwebapps

I confirm that all runs fine on my tomcat7 server when I deploy from eclipse!

In eclipse console I get:

Apr 08, 2014 3:26:59 PM org.apache.tomcat.util.digester.SetPropertiesRule begin
WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.j2ee.server:my_project' did not find a matching property.

Now: The problem It is when I deploy the same app (using a file .war) in the same tomcat7 server /var/lib/tomcat7/webapps

I can open the my initial page web BUT without data,

I see in the log:

INFO: No Spring WebApplicationInitializer types detected on classpath

When I restart tomcat7 I get in the log file:

Answer 1

I found the error: I have a library that it was built using jdk 1.6. The Spring main controller and components are in this library. And how I use jdk 1.7, It does not find the classes built in 1.6.

The solution was built all using "compiler compliance level: 1.7" and "Generated .class files compatibility: 1.6", "Source compatibility: 1.6".

I setup this option in Eclipse: PreferencesJavaCompiler.

Thanks everybody.
