Google AppEngine Blog :

My name is Praveen Alavilli (@ppalavilli) and I work as a developer evangelist for PayPal's X Platform at PayPal.com. I want to take the opportunity to introduce you to our new open source toolkit for Google App Engine that provides an easy way to integrate your Java apps running on App Engine with the new PayPal'sAdaptive Payments API. Currently this is a Java toolkit explicitly for App Engine Java, but a Python version will be coming out soon.

Recently Apple released Safari 5, which included a bug where non-integral right-shifts were not being evaluated properly. There were several reports, both internally and externally, of GWT-based applications unexpectedly crashing when running in Safari 5 (including Google Wave). Upon further inspection of the crash, we determined that the bug is triggered when calling several of GWT's array sorting methods, which in turn perform non-integral right-shifts as part of the compiled code.

During the last few days we have been working on the base layout for our Discovr Administrator App. We have chosen GWT + AppEngine as our implementation platform and while getting things to work we found a few pitfalls implementing a flawless layout using GWT 2.0 and their new UiBinder approach.

On this post we wanted to share some of our experiences and will show you a couple of ways how you can use GWT + UiBinder to implement some basic web layouts.

Fastcall is a prove of concept electronic directory letting people find their contacts in less than 4 clicks. But, behind that, it's a web application based on the last technologies like GWT 2.0, HTML5, Objectify , CSS 3, Modding and deployed on Google's AppEngine. Moreover it can be used either on a simple web browser or a smartphone in two particular modes(online-offline), the benefit of the offline mode being: getting access to the application at anytime and quick navigation due to the cached mode of HTML5.

With GWT 2.1 Milestone 1, you are one step closer to being able to build business apps for the cloud as easily as ever. Using GWT’s new data presentation widgets and MVP framework, you can create great looking web apps that run fast, whether you’re interacting with 25 records or 25 million records. This is accomplished by designing the widgets to be extremely lightweight, using DIVs and HTML instead of composites and widgets, and an app framework that makes it easy to fetch only the data you need, when you need it.

If you're a web developer, you're certainly aware of all the buzz surrounding HTML5 : "the end of Flash", "the second coming of the thin client" and several other statements with varying degrees of hype and accuracy flood the web. Flame wars aside, HTML5 is finally coming, and that's really great news.

But HTML5 projects are far from being a reality, as the standard hasn't yet been released, so where to go for guidance ? And more importantly, what does HTML5 really mean for developers ? You could read the draft version of the specification but that would be overkill (seriously, you don't want to read 200 thousand words) or you could try to find a concise presentation of the noteworthy additions to the venerable HTML standard, with code examples if you're lucky.

Well, I have good news for you, such presentation exists, and it was made by a couple of Googlers (Marcin Wichary and Ernest Delgado), it's interactive, it has live code examples and most interestly, it is implemented with HTML 5. You can find it here.

But what if you're like us, a GWT developer, what about then ? How can you start enjoying from the nascent HTML 5 support in modern browsers ? Well, I have some more good news for you : we (Sfeir's employees) have made a GWT port, and deployed it on App Engine. You can browse and checkout the code at our Google Code repository.

The GWT version supports internationalization.

If you're more of the jQuery type, you might be interested a jQuery presentation, based on the original HTML 5 slides. They're not really about HTML 5 but they're a cool HTML 5 example nonetheless.

gwt-cal is a web-based calendar component similar to iCal, Microsoft Outlook or Google Calendar. It can be included in any Google Web Toolkit (GWT) web-application, and can be easily themed to resemble your favorite calendar tool.

It is getting better and better.
