Google Web Toolkit throws java.security.AccessControlException

Question

I'm trying to read a sqlite db from the server side code in my gwt project. It throws AccessControlException. I looked a lot on the web and all solutions seems to be disabling Google App Engine, but when I do this, I can't run my project. I'm new to GWT and I have no idea where it runs when Google App Engine is shut down. I look for possibly this two solutions: Any setting that Google App Engine is set to be able to read any file, or other engine that I run my application on. Thanks

The problem is that Google App Engine (GAE) does not support sqlite (I assume you are reading it using JDBC).

If your intention is to make a GWT project that will not be deployed on GAE, you should create the project disabling this feature from the very beginning, because afterwards its a nightmare as you are experiencing right now.

If your intention is to deploy in GAE, you must use the google's persistence mechanisms (JDO) to store your data. SqlLite is off the table here.
