App Engine SDK 1.3.3 released

Although the Eclipse plug-in has not updated yet, I have tried to download the zip file. This is only a minor updated version with limited features. One of the most important thing worth to pay attention is the SQLite support for Python. Despite of the official word "Note that this feature does not add SQL support to the App Engine SDK or service", it is a great advantage for developers to harness the benefits of SQLite. Just wondering when will they expand the support to Java field. It seems Java is always a step backward compared to the development team of Python.

New Warning Message on Google App Engine

I just noticed a pretty new warning appears in the log of App Engine:

"This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application."

Previously, there is no such thing highlighted the reason why sometimes a simple operation might take longer CPU hours than expected. Now with this handy warning, things are much clear and you don't have to worry about any internal coding issues with your project.

However, if Google can solve this issue, it will be much better. Currently, in order to avoid such re-loading time waste, I have to reduce my cron job frequency to once per minute. Yep, when it runs in 2/min, App Engine will complain every time, and the overall CPU cost is even higher than the more frequently job. Ironically, Ridiculously, huh?

I know some guys are working this issue now, hopefully it can be fixed in the near future.

Install spring 3.0 plug-in in Eclipse 3.5

Actually this should be a pretty old topic, since I have done the same thing more than 5 times. However, without note down all the details, each time I have to google to solve some issue. Every time I just wondered why in the first place I keep this details down, now finally I decide to write all this down in case next time I have to google again and again.

So what you need to do is simply use the install new software tool in the Help menu. The address of spring plug-in is:http://springide.org/updatesite .And actually all you need is pretty clearly written on the web site of http://springide.org/project/wiki/SpringideInstall.

However, there might be several issues you will encounter. In my situation, you will always get a complaint about the missing component of "package org.eclipse.ajdt.internal.ui.lazystart 0.0.0". This package belongs to AJDT (which stands for AspectJ Development Tools) could be downloaded through the site of http://download.eclipse.org/tools/ajdt/35/update, and relevant info is here: http://www.eclipse.org/ajdt/downloads/.

After that try the spring plugin once again, in my case no complain any more and you should be able to get dirty with Spring finally.

PS: I have tried this method both in Ubuntu 9.10 and Mac OS Snow Leopard. Haven't try on Windows so please forgive me if it fails with Microsoft.
