Question

I am trying to deploy Spring roo project on Heroku. Everything went just fine. The deployment process was successful. but after running it on server, I got Following error:

HTTP ERROR: 503

Problem accessing /. Reason:
Service Unavailable 
Powered by Jetty://

The application is working perfectly on localhost:8080. but it gives 503 error when run from heroku.

I am following this URL (step by step): https://github.com/heroku/devcenter-spring-mvc-hibernate

This is my logs:

Solution

Well, I got solution.. The issue was following error from my logs:

java.lang.UnsupportedClassVersionError: com/palak/domain/Visit : Unsupported major.minor version 51.0

java.lang.UnsupportedClassVersionError happens because of a higher JDK during compile time and lower JDK during runtime. My classes are built up using java 7. and I was running my app using openJdk 6 (default). All i need to do is to add new file to my root directory of project indicating that I want to use particular version of java,In my case, I want to use java 7, for instance.

So, I have to make new file "system.properties" and paste this line inside of it: java.runtime.version=1.7

Now reloaded application and uploaded again from git. Now Everything works Perfect. Hope this helps someone. Cheers. :)
