root@:~/apps/java# cf push java-test -p do_test.war

Hi,

It seems like a file system related error. Could you push the ruby test app included in cf_nise_installer?

I pushed the sinatra app successfully.

What could I be doing wrong with the java app?

Then the problem you got was caused by the java buildpack or your code.

Could you try to push a simpler java app?
