How to create a google app engine project doesn't work

[johnny]

Hello,

I followed your How to create a google app engine project.
When I start the server on my machine using dev_appserver.bat I got an
error:

java.lang.NoClassDefFoundError: java.io.FileOutputStream is a
restricted class. Please see the Google App Engine developer's guide
for more details. (development.clj:0)

Seems FileOutputStream is not on the whitelist. Is there a
workarround?

With regards

[johnny]

Can anyone help here?

The issue is the logging code in the config/environments/development.clj
file. Google app engine doesn't allow you to access the file system, but
the current logging code wants to write logging statements to the file
system.

You'll need to remove the code and replace it with the logging system in
Google App Engine. I've done it before, but apparently forgot to update
the wiki.

The easy solution is to set :use-logger? to false in your
config/environment.clj file.

P.S. Sorry for the delay replying. The holidays are screwing with my
ability to support Conjure right now.
