[Evan W. Patton]

So it looks like the server is starting okay. The stack trace is just a failure to check for a new version of the SDK, but it might be indicative of other permissions problems. One thing to check is whether SELinux is running and in enforce mode as it may be blocking Java from receiving requests on port 8888. If so you would need to either switch to permissive mode or add an SELinux allowance for that port. Another thing to check is run sudo netstat-ntlp | grep 8080 and verify that you see Java running on that port and not something else.

What is the output of the following commands?

sudo netstat -ntlp | grep java

curl http://localhost:8888/

Evan

[Jeffrey Schiller]

Also make sure you are using an older version of the App Engine SDK. Due
to a bug in Google’s later versions, you need to run a version of 1.9.27
or older.

thank  you very muck,now i can visit my server by disable update check,but i got new error: Server error: could not save one or more files. Please try again later!,

i have give appinventor and appengine dictionaries the most permission,but does not work.

Is this really the last item in the log:

>>> Sep 21, 2016 8:37:28 PM
>>> com.google.appengine.tools.development.DevAppServerImpl doStart
>>> INFO: Dev App Server is now running

The log should continue when you attempt to access the site. Such log
entries might provide clues as to what is going on.

This line:
>> https://appengine.google.com/api/updatecheck?runtime=java&release=1.9.42&timestamp=1468608347&api_versions=['1.0

causes me to believe that you are actually running version 1.9.42. That
version is too new and will not work.
