[appengine-java] Re: Set the Timezone
Is there a way to set the timezone for my application? TimeZone.setDefault(TimeZone.getTimeZone(GMT-8:00)); Have you actually *tested* this on App Engine? This should be inserted in the servlet initialization code? thank you, -g. If you use JSTL, try the following setup in web.xml: context-param param-namejavax.servlet.jsp.jstl.fmt.timeZone/param-name param-valueGMT-8:00/param-value /context-param You can change GMT-8:00 as you want.

Re: [appengine-java] Re: Set the Timezone
Hi George,
Is there a way to set the timezone for my application?
TimeZone.setDefault(TimeZone.getTimeZone(GMT-8:00));
Have you actually *tested* this on App Engine?
Yes.
This should be inserted in the servlet initialization code?
You can insert the code when the servlet initializes as follows:
@Override
public void init() throws ServletException {
TimeZone.setDefault(TimeZone.getTimeZone(GMT-8:00));
}
When I reply something, I always try it.
Hope this helps,

Hello, Some visibility on the roadmap would be great. I think in the last month GAE has already improved a lot. There are quite some open issues that are often listed against the use of GAE. I believe if we knew that they will be addressed at some point in time it might help. Personally I see two major things for my applications: - improve spin up or keep alive option - full fledged search I guess a good MVC framework and better Spring integration would be great as well.

[appengine-java] Re: blobstore lucene search index
My search engine is a full-text proximity based engine which you can check out in action in an Android add called NewsDroid. The indexer part indexes Reuters News semi-continuously and a user searching on Android will be shown query hits in matching news where as many keywords as possible were found together. This is, btw, an XML search engine -- in addition to keywords you need to specify in which elements to search for text passages. I am currently working on another application of the engine, beyond news. The original version of the search engine used a number of files to store indexes. As I ported the system to GAE I had to figure out ways to store and use indexes stored as blobs in the Datastore. Basically, any file can be split into chunks of up to 1,000,000 bytes. Things work OK, but not great on GAE. Loading indexes into memory is taking time when servlets are restarted.
