[appengine-java] Re: Cannot install app engine plugin in eclipse 3.5 (Galileo)
Hi Jason, thanks for your reply. I found the problem was not in the connection but in my sluggish hardware. The packages were downloaded but somehow, install process did not finish in time, so it has timed out. NOD antivirus (ekern.exe) ate 100% of my CPU during installation. Turning it off helped me resolve the problem. After several attempts to install the plugin, app engine and gwt my eclipse environment got corrupted. Plugin with SDKs was listed as installed but there were no options present in the GUI (no google icons in toolbar, no menu File/New/Web AppIication project,...). So I have removed .eclipse directory from home directory, restarted eclipse and then installed the plugin with SDKs again. It works now.

[appengine-java] Datanucleus initialization performance
Since Google App Engine will power down the app if there aren't any requests for ~10 minutes, it has to re-initialize your application often. Not a problem I was able to trim my app init down to about 1.5 seconds, so its reasonable, but datanucleus itself takes about 5 seconds on top of that (and I only have 5 persistent entities!). This is a real drag on my app and I almost want to keep it awake with a pinger... Any way to speed up initialization? I'm using JPA.

[appengine-java] Re: Querying by Category class
I have changed to
query.setFilter(tags.contains(' + aTagValue + '));
and it still works!
It took me a while to get into this concept, that although it's a
filter clause it's written in java object style and not SQL style, I
mean:
NOT tags contains tagParam BUT tags.contains(tagParam) as you wrote
Thanks

It may work, but is actually invalid JDOQL and you should always use
valid JDOQL syntax like
tags.contains(tagParam)
and your current query would fail in future releases.
