Can you use Java EE frameworks with the Google App Engine?

Question

I have been working on a small web app using the Stripes framework. Now that the Google App Engine has added support for Java, I am wondering if I can convert it to run in the Google App Engine to save costs on hosting.

Answer 1

Yes, it supports servlets, so it should support Stripes just fine.

According to the App Engine documentation,

App Engine uses the Java Servlet standard for web applications. You provide your app's servlet classes, JavaServer Pages (JSPs), static files and data files, along with the deployment descriptor (the web.xml file) and other configuration files, in a standard WAR directory structure. App Engine serves requests by invoking servlets according to the deployment descriptor.

Thanks for the quick answer. I assumed that the Google App Engine would have support for existing J2EE web frameworks, but wanted to make sure. – Jackdaw

Answer 2

There seems to be a little snag (and workaround) because of the missing access to a local temporary directory. You need to provide your own file upload facility (or disable the feature).
