Db4o with Flex Data Services

I have just recently begun experimenting with Flex Data Services and db4o. db4o is an embedded object database for Java and .NET. I think using Flex with db4o would be very cool. It basically comes down to configuring the destination correctly.If anybody has sucessfully integreated these two technologies please post a comment about your experience.

FDS Project Template Update

I have update the FDS Project Template . I commented out the Tomcat specific library includes so that the build will work for those not using Tomcat. I have also changed the CATALINA.HOME property in the build.properties file to WEB.ROOT.

Java Application Server PE

If you are trying to use the Flex Data Services Project Template with the Java Application Server PE you might get the following error.

Error: java.security.AccessControlException: access denied (java.lang.RuntimePermission createClassLoader)
Cause: the default settings of the SUN server policy settings does not allow classloaders within webapplications.

Solution: Simply replace the policy file with one that contains the following grant entry:

edit: C:\Sun\AppServer\domains\domain1\config\server.policy

add: This towards the bottom of the policy file.

grant {
// Allow everything for now
permission java.security.AllPermission;
};

Flex Data Services Project Template

I just recently starting using Flash Develop 2.0. I was motivated by Keith Peter's ANT based project template that I created one for Flex Data Services. This tutorial is still in its early stages but I would like to get some feedback from other developer. This tutorial requires that you have Ant, Tomcat 5.5 and Flex Data Services installed.
