Google App Engine

One month after I started writing my first Google App Application I had reached more then 1000 Page View per one day!!!



One of the great advanatges of GAE over creating my own Web Server is that robutness of Google servers, My application is up 100% of the time, And after writing the application in correct way without consuming too much CPU per request and handling exceptions the application can be used anytime by the users.



The question is what would happen when GAE would support also Java, I realy don't know how I would be able to convert my application from Python to Java

Google App Engine in Java Language

As A Java Developer it is very hard to use Google App Engine.
As for now Google App Engine supports only Python Programming language, Trying learning and writing Python languages can be very frustrating when you are used to the good pleasing Eclipse IDE.

Then I found this nice project:

http://code.google.com/p/java2python/

You can write you Google App Engine Application in Java Language and then just convert it to Python and upload it to Google Servers!!!

Enjoy

Google App Engine and GWT

First there was GWT - Google Web Toolkit a very nice framework to develop Ajax applications in Java language which then translate to JavaScript, It worked with Tomcat Web Server. Then Google decide to release Google App Engine a service which provide the ability to develop applications in Python language and deploy them on their servers for free and provide datastore which is like DB to store data.

It seems like their is no syncrhonization at all with the two groups GWT and Google App Engine, once Google goes for Java and then for Python, Is there any direction to which Google wants to go to?

In their website they claim that they choosed Pyhton because it is secure language, There is no more secure lagnuage than Java, How would GWT developers would deploy their applications on Google App Engine, would they need now to convert their code to Python? I really confused

Why not using Google App Engine

After worked several days with Google App Engine, I was realy dissapointed, It seems that since it has just released and it is in "Preview Release" it contains some bugs and since Google choose Python as the programming language it make it hard to develop for programmers which don't know well Python, Here are the problems that I come with

• Python is VERY hard language to develop applications which required Unicode, Maybe for english applications its not so bad language but when you try writing something which is not english you need to find yourself using decode, encode, unicode and other awful methos.
• It seems that urlfetch method which retrieve data from other urls doesn't support unicode
• I tried to upload my datastore to the application server, when I do it locally it works, however when I try to upload the datastore remotly on Google Servers it fails.
• Datastore also doesn't support unicode characters, everything has to be in english
• Sometimes after uploading the application to the Google Servers it says error 500, However the application works just find locally
• Python language is the only programming language I know which requires not using Tabs inside the source code and it doesn't use { and } characters to define block but rather it looks on where the line begins. There are much more advance programming languages like Java which could fit more to be used with Google App Engine

In summary I think that I would wait some time before Google App Engine would have more stable versions.
