I'm a newbie to Google App Engine. I'm playing around with it since we're going to be using it in a college Java class. I have Eclipse Java EE IDE, Indigo release. I'm using jdk1.7.0_02, which is the latest one as far as I know, and GAE's 1.6.1 SDK.
I made a new web application named MyFirstApp, package name myfirstapp. Unchecked "Use Google Web Toolkit". I let it generate project sample code. This thing works perfectly fine locally. I can connect to localhost:8888 and see the index and use the servlet perfectly. The problem arises when I use it after deploying the app. This is my app's address: http://ist421tvj.appspot.com I changed appengine-web.xml's application line to include the ist421tvj and deployed it. The index works fine. The servlet does not. The error below appears in my logs. Any help would be appreciated, because I have no idea how to begin troubleshooting this. 1. 1. 2012-01-28 19:34:19.573 /myfirstapp 500 70ms 0kb Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.77 Safari/535.7 71.61.100.98 - - [28/Jan/2012:19:34:19 -0800] "GET /myfirstapp HTTP/1.1" 500 0 "http://ist421tvj.appspot.com/"; "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.77 Safari/535.7" "ist421tvj.appspot.com" ms=70 cpu_ms=163 api_cpu_ms=0 cpm_usd=0.004576 instance=00c61b117ce146242dc10134e4c575d18906 2.
