Cannot deploy Google App due to errors

I have created a simple application using the Google App Engine

Environment

I was able to create a sample application and run it locally.

When I try to deploy it gives me an error

Error in eclipse

Deploying 'applicationname' to Google has encountered a problem. Unable to update app: The application contains Java 7 classes, but the --use_java7 flag has not been set.

See the deployment console for more details Unable to update app: The application contains Java 7 classes, but the --use_java7 flag has not been set.

The logs show

Unable to update: java.lang.RuntimeException: The application contains Java 7 classes, but the --use_java7 flag has not been set. at com.google.appengine.tools.admin.Application.createStagingDirectory(Application.java:576) at com.google.appengine.tools.admin.AppAdminImpl.doUpdate(AppAdminImpl.java:370) at com.google.appengine.tools.admin.AppAdminImpl.update(AppAdminImpl.java:53) at com.google.appengine.eclipse.core.proxy.AppEngineBridgeImpl.deploy(AppEngineBridgeImpl.java:433) at com.google.appengine.eclipse.core.deploy.DeployProjectJob.runInWorkspace(DeployProjectJob.java:148) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:53)

I see someone has encountered the same error before

Failed to deploy to Google App Engine because --use_java7 flag has not been set

I installed JDK 6 but I could not get the application to work either.

What are my alternatives to getting the application to work? - some thoughts...

You have to use JDK 6.

Java Overview Docs

App Engine runs Java applications using the Java 6 virtual machine (JVM). The App Engine SDK supports Java 5 and later, and the Java 6 JVM can use classes compiled with any version of the Java compiler up to Java 6.
