APIs in Action

There are a number of APIs released by various services everyday. I always "want" to play around with them and understand the possibilities that they provide but most of the time not do so. Ben Lisbakken over at Google has utilized his 20% of time to build a playground for Google APIs. I am sure lot of people are going to find it useful to understand possibilities and scenarios that Google APIs can enable. Also, the webapp itself is built on Google App Engine and released as a open source project.

MyEclipse HQL

Though it has been few versions since MyEclipse had support for Hibernate and HQL, I only had a chance to play with it recently. It has a nice feature set and the HQL editor is tied Dynamic Query Translator which gives on-the-fly translation for HQL queries. This provides for an easy way to debug queries and validate them.

In order to open a HQL editor you need to create a file with .hql extension and also have an active hibernate configuration file. This took me a while to figure out. In order create an active Hibernate Configuration use File -> New -> Hibernate Configuration File and setup the connection parameters for the database.
