Google App Engine - Early Look at Java Language Support

[wartem]

Mind-blowing!

[VondaFoni]

The JAva language is kind of a complicated matter.

[Quaaludedude714]

Opend up my mind :) QC

[zeetu4u]

awesome tutorial

[yangliweng]

hi ,r u using eclipse or jcreator?

is eclipse free of charge?ty

[barizonte]

@yangliweng He is using Eclipse with Google App Engine Pluging for Eclipse. Both Eclipse and the plugin are completely free

[samilughmani]

From where can i get these 3 files that you put into your project?

[raywillway]

Bad

[NLstb]

this is for nerds.

[Marchof31Days]

Is it possible to have access to the example project? I have a presentation on this in which I only have to talk about how it works, not actually develop anything.

[skjoyner]

OK if u have perfect vision. Android sucks for the visually impaired folks. If you wear glasses buy iphone or BB. You will be able to read the screen without having to reach for glasses 100 times a day.ALL android phones have TINY TINY text and no way to enlarge it. iphone & BB care about the visually impaired & allow system wide font size large/exlarge etc, Android don't give a rat's ass for the visually impaired Complaints for 2 years fall on death ears, Google research it. It's the TRUTH

[blahmobile]

Was anyone else amused by their use of Firefox instead of Google Chrome?

[nbns]

@blahmobile no, care about your own browser and let everyone else use what they PERSONALLY prefer.

[tFuj18]

be easy to understand

[MuzeTV]

@tFuj18 he's like doing it on purpose! I didnt get much of what he's saying! that nerdy idiot!

[amazingmiki]

Anybody have those source files?

[nbns]

@amazingmiki yes, google this and it will be your first result (inside the tutorial): google app enginge tutorial java

[TheGayarP]

This is GR8

[nyeck500]

This video is the realy intoduction to the google new tecnologie provide.

[ken0624700]

Wish they provide traditional RDBMS supports like MySQL... GWT sucks...

[bhaktadn]

This is great!!

[jordanmicle]

awesome... by the typing speed...

[dan221081]

Looks very promising , Keep up the good work.

[Mscharneth07]

where's the url ?

[eclipsal2008]

I have to ask, can I run RED5 with app engine?

[rohanrawat99]

NICE JOB

[ashthegamer]

Where can I download Eclipse?

[MrBerttube]

Try writting "where can i download eclipse" in google search engine... :P

[FlightSimXtreme]

eclipse(dot)org

[peppeddu]

Heavily scripted.

If he reads from the teleprompter he needs to put the camera farther away.

His eyes are going left and right and he writes code like copy-n-paste.

[SkyWalker2233]

man, this guy writes code like a programmed robot,,

[froma2zi]

Wow , Thank you google i love it.

[durfee84]

I don't think he read the Terms of Service, haha

[TerryGilliam5]

lol. was he using firefox? in a Google video?

[bozurich]

this was published before chrome for mac

[TerryGilliam5]

ah. understandable, then

[Alfredofefe1]

sei lá google que tal vocês porem videos em pt-br assim ninguem vai querer se cradastrar no google sem saber a suas super boas funcionalidades

[IMMBBR]

legal

[JohnnySoftware]

This is one of the finest introductory videos to a new programming technology I have ever seen. I had more concerns than attractions to cloud-based computing before I watched this video. However, after viewing it and investigating the API support Google provides for popular web services, I am won over to cloud computing. JDO, JPA, JSP, JSTL, servlet, and GWT APIs are familiar and well-liked by Java programmers. App Engine is not a weird environment. It is an environment built from favorites!

[d00derman]

Ew, I like the tools but query code in the jsp?

[ricnanet]

amazing! you is the guy

[vichuiswizard]

hey i get an error!!!!>......

it says

Error 500:

javax.servlet.FilterChain is a restricted class. Please see the Google App Engine developer's guide for more details.

wad do i do now!!!!

[iuayfbujcwe]

try not using the blacklisted classes :)

[vichuiswizard]

could u be pls clear wad do u mean by blacklisted classes?!!!

[nyeck500]

How we can get the blacklisted classes?

[nbns]

@nyeck500 code.google.com/appengine/docs­/java/jrewhitelist.html

this is the "whitelist"

[KyLeMcFa]

yeah yeah mate but can u do a rubix cube drunk?

[ACSmartBoy1234]

voila!

[booooo201]

wtf y is voice weird?

[LinMathias]

How do you also deploy the data store with existing data on appspot? I noticed that when deploying the app (as shown in the video), the data store will be empty again.

[wesleyseidel]

Muito bom... rápida introdução ao conceito... gostei !

[gimmeshelter1969]

Actually I'm surprised this only rates 32k views; thought there were more java web developers out there who are looking for a way to get their webapps out to the "cloud".

Thanks Google - this is awesome!

[luisdanielmesa]

1:53 "Luckily AppEngine ships with a development webserver that mimics the production environment"

Actually i'm starting to think the development webserver is better than the production webserver... when i work and upload to the production server a few times, it goes crazy... I guess it doesn't update the cloud fast enough to notice my change in a particular JavaBean, which inevitably ends up throwing a UUID Exception telling me it's not the correct object.

[buletov]

You can do all this so much easily in Delphi using IntraWeb (and optionally Direct Oracle Access for data storage), by using data aware components and writing only minimal amounts of (clean) Delphi code.

[asterix040173]

only one thing... i whish i was a programer !

i love that staff. i`ll try anyway !!!

[gonzalochenzhen]

Thank you Google. Very great Move. Java is the best languaje that is one on one with design and easy to implement design patterns. Java is very easy and clear with a great amount of jar libraries that makes the work for you. And GWT, never for me has been that easy to create an ajax basic application.

[najolesor]

WOW looks like easier than using blueJ app

[stevenqirkle]

As a young developer, Google, Amazon, and Salesforce have me incredibly excited for the future of software development. Currently I'm working with Salesforce's "Apex" platform - and having great success at delivering functional code quickly at a fraction of the cost of traditional software development. (Unfortunately, this functionality comes at the cost of Salesforce's admittedly mediocre UI).

These services will allow individual developers to do amazing things.

[chiliconcarne2006]

CRAP..........

I spent 2 hrs figuring this out, i should have watched this vid.

[rwmtiger]

(o,O) hmm. what?????

[andrijaperovic]

hey everybody,

i am overriding to a different port because there is already a service on 8080? when i run it in my browser i still get a failed to connect to localhost:8081 even though it says the server is running on that port in eclipse...

[vilan]

Only good thing about the Java support is that you can now use Scala.

[bchi49]

Actor should work?

[ksjagan]

Probably. FYI, this guy says that he is the Product Manager of Developer Products at Google!

[srav953]

Is Python supported? Please, I need to know?

[luckydev89]

yes. That was the first language supported in google appengine :)

[chifufunie]

will spring be supported? if you don't support spring, i will not use it.

[zeo604]

amazing, cloud computing will rocks!!!

[CognosSquare]

Yes! Its already molesting basic grammar.

[bytedildo]

so basically i can create a grails project, create a war and upload it :D Nice!

[TiLeNpWneD]

It's realy awesome to know that App Engine will support an enterprise class language such as Java apart from Python.

[DragonMonkeySlayer]

That's nice to know - html templates used are much nicer than embedding query code etc into where html should be. But of course reusability is important :)

At the moment I'm writing a middle layer in python for accessing the database so that I don't couple my view with the db.

I will have to keep on top of this Java Support for app engine - Maybe I'll switch to it eventually :)

[wilsonferro]

Com certeza o Google conquistará a comunidade Java adicionando o suporte a linguagem Java no Google App Engine. Parabéns!

[DragonMonkeySlayer]

Cool stuff, but I have to say that python looks like it has much less overhead... no persistence factories and annotations...

Java is more popular than python though, so at least you might be able to find more programmers.

[ArchSaur]

The "overhead" here comes from the way examples are made, not that directly from Java itself.

IMO Java code here is more reusable/extensible compared to Python. But it doesn't have to be.

Factory class com.google.guestbook.PMF here is redundant and may not be used at all - it's a singleton wrapper. Just call JDOHelper.getPersistenceManage­rFactory(...). Minus one file.

You may not have JSP for view but use stringtemplate resulting in similar code to that in Python and ~same HTML template file.

[ddeveloperr]

Azure Rocks GoogleAppEngine Sucks

[enterneo]

this is spectacular, thank you google

[erazorx]

Wow very nice!

[udaiibhaskar]

That's what I wanted and many others wanted.... Good Work.

[theinfinityone]

Google keep stunning

[guilhermegrg]

At last ! finally with free hosting, Java web apps will hopefully grow in popularity !!!

And with support for Groovy/Grails/JRuby/JRails I just can't wait to see what developers will make!

Great move by google!

[robertjchristian001]

Great work. As simple as this is, it is much more complicated than the Python version!

[clementyew1]

Very wise move by Google indeed. Java really lacks a low cost, scalable and easy hosting platform.
