Google App Engine for Java open for business

So it looks like since yesterday, you can hook up your favorite war file over at Google.  Before you pack it in and tell the local web master their job has just been automated … better look at some of the limitations.

App Engine Java Overview – Google App Engine – Google Code

App Engine runs Java applications using the Java 6 virtual machine (JVM). The App Engine SDK supports Java 5 and later, and the Java 6 JVM can use classes compiled with any version of the Java compiler up to Java 6.

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.

The JVM runs in a secured “sandbox” environment to isolate your application for service and security. The sandbox ensures that apps can only perform actions that do not interfere with the performance and scalability of other apps. For instance, an app cannot spawn threads, write data to the local file system or make arbitrary network connections. An app also cannot use JNI or other native code. The JVM can execute any Java bytecode that operates within the sandbox restrictions.

See Servlet Environment for more information.
