As far as I learned there is no possibility to write directly to the filesystem on GAE.
Since the templates are stored in the app/view directory how do you solve the problem to have some interface that is used to editing the templates that are being used? Is it possible to have template editors who have access to the new version's template files, or they must work on a separate development server and when everyone is done then the app admin can upload the new version to GAE?
IMO the best solution is to store the templates directly in GAE? In the datastore itself or in the blobstore... I think nothing prevents Play! from extracting its VirtualFile from a datastore instead of the file system. But, you need to tweak a bit this part of Play! I don't think it's really terrible but it's not trivial.
You can save them in blobstore so it will slow. You could make a hybrid solution using Memcache + Datastore or play around with the Files API

Is it possible to upload files to a web browser application (such as Dropbox) directly from a document management system (DMS) such as iManage (aka Worksite, Filesite, HP Autonomy)?
If not, what are the best ways of getting around this and enabling simple upload of files from the DMS to web applications?
If you are trying to share documents via a dropbox like solution, you might want t consider LinkSite. It is more manageable, which is quite a positive aspect since you will probably working in a legal environment.
More info can be found here: http://www.irisecm.com/hp-linksite-the-secure-and-enterprise-alternative-to-dropbox/

By the way, LinkSite is rebranded and now called iManage Share.
If you are looking for a seamlessly integrated third party application you might want to consider Litéra Sync.
Our app is a sort-of self-service website builder for a particular industry. We need to be able to store the HTML and image files for each customer's site so that users can easily access and edit them. I'd really like to be able to store the files on S3, but potentially other places like Box.net, Google Docs, Dropbox, and Rackspace Cloud Files.
It would be easiest if there there some common file system API that I could use over these repositories, but unfortunately everything is proprietary. So I've got to implement something. FTP or SFTP is the obvious choice, but it's a lot of work. WebDAV will also be a pain.
Our server-side code is Java.
Please someone give me a magic solution which is fast, easy, standards-based, and will solve all my problems perfectly without any effort on my part. Please?
Not sure if this is exactly what you're looking for but we built http://mover.io to address this kind of thing. We currently support 13 different end points and we have a GUI interface and an API for interfacing with all these cloud storage providers.
I have created a GWT application and now want to deploy it outside GAE. The reason I wish to deploy outside the GAE is the Sandbox security feature of GAE, which disallows me from writing files to my system. I store my data in the form of an ontology (.owl file) under my '/war/WEB_INF' and I want the end user to be able to modify (write to / save) this file through the server.
I understand that GAE does not let me do this, but is there a paid Google Service (e.g. google apps) that would allow hosting a GWT application which would allow writing files to the system? For instance, like an add-on to GAE?
If not, what solution would you recommend to host a GWT application (that would let me write a file to the WEB-INF folder) on the web?
EDIT: I solved this by deploying the GWT project as a .war file and hosting in TomCat.
I'm very new to GAE, but in case you haven't looked at their experimental write/read blobstore services you can check that out here. They have a similar API for python I believe. It's ofcourse stored on the GAE blobstore and not under /war/WEB-INF/ directory but It does allow a possible solution to what you're looking for.
Also, if you're looking to run your own server (possibly on EC2 for example), then you might want to look into AppScale. But I, personally, would stay away from that as a solution because I highly doubt that AppScale performs as well as google's GAE web servers and furthermore lacks the same degree of support/development.
Have you ruled out something like creating an Owl Entity to hold your ontologies, and arranging for *.owl requests to be handled by using that as a key name to find and serve the corresponding Owl? That's really simple code.
GWT is primarily a client side technology. GAE is a server side technology. You seem to be getting GWT and GAE engine mixed up with each other. GAE can work with almost any client side technology, and GWT can connect to many different back end platforms.
Are you trying to move your back end code directly to a new platform? Are you planning on rewriting the back end for a new platform, but keep the GWT code? What is your goal for this application? To be used by you and a few friends, or by thousands of people? For free or paying customers?
If you want to move off of AppEngine, you can switch to pretty much any java hosting service that you want - anything from a tiny shared VPS up to a Amazon EC2 mini cloud of your own. I don't think google offers generic java hosting. I don't know how you have built your application's back end, but you probably used servlets, which you should be able to get working pretty much anywhere.
If you want to stay on AppEngine, you should think about whether or not you can break your owl file into smaller sections that can be stored as entities in the database.
Whichever platform you choose, if you are planning on serving more than a few people, you will need some way to prevent one giant owl file from becoming a huge bottleneck.
I am a newbie programmer and i dont yet have any idea of the WEB. I wish to start learning a technology that will allow me to build websites( database driven) i dont know which one to choose. I know some actionscript3 and flash.
Is it possible to create a database driven website using these alone? Or do i need to learn any other technology? If i do then what should i learn? I know j2se for the desktop and oracle SQL/MySQL
please show me a path. Also wanted to know if there is any technology like Wordpress for J2EE/flash
OK so i finally got the feeling that i need to learn PHP anyway along with css and javascript. So it is fine. Also another query. Which CMS should i consider? Wordpress or Joomla?
You can develop a database driven website using Flash, but only in the same sense that you can develop a database driven website using AJAX. That is, you can build the front-end using Flash/ActionScript but the back-end is built using other technologies. Just like working with JavaScript to develop a front-end, from ActionScript you would be communicating with Java or PHP or Python or something on the server using RESTful calls and then actually working with the database in the server-side scripts.
Honestly = this question is too broad and generic, and answers are easily found with some google searches.
That being said = of course you can build a data driven flash site. The one caveat here is that flash itself is fundamentally client-side technology, so we must rely on other remote tech to do the heavy data lifting. The options are profuse.
For example, a developer might create a front facing presentation in Flex, which is the streamlined, data-centric extension of pure flash. His database interactions are written in php, and these are constantly called upon to deliver content to the user.
So - what technologies to use? Whatever you know. And if you don't know, then learn the ones that are closest to what you know.
Finally, although I am a die-hard fan of flash, this type of project (you didn't specify what you had in mind) could be done with many different technologies. So - maybe flash is the right answer, but maybe javascript (ajax) could manage the same thing and do it without the need of plugins.
Yes you can develop database driven site in flash/action script but you still need and back-end technology i recommend you to check WebORB you can develop the back-end using Java, PHP, or .NET In addition you can use Flash Remoting technology Flash/Flex to communicate with a back-end
Flash can't be directly connected to database. You must use another technique which would be "mediator". I have developed Flash game with MySql database and PHP and I recommend you to use this combination. Here is visually presented this kind of communication: http://www.youtube.com/watch?v=gRi-oxjFfCU
yes, it is possible to crate database driven website with flash and action-script. You would get an XML file when you do action script in flash, so you can store nodes of that XML file into database(mysql). You can then create an Admin interface to manage your database contents, that would indirectly change your xml nodes. So basically you can edit the xml file and store it in the database.
I'm working on an app engine project (java). I'm using the jdo interface. I haven't pushed the application yet (just running at localhost). Is there a way I can totally wipe my datastore after I publish? In eclipse, when working locally, I can just wipe the datastore by deleting the local file:
appengine-generated/local_db.bin
any facility like that once published?
I'm using jdo right now, but I might switch to objectify or slim3, and would want a convenient way to wipe my datastore should I switch over, or otherwise make heavy modifications to my classes.
Otherwise it seems like I have to setup methods to delete instances myself, right?
Thanks
you can delete it from admin console if there are not much enitty stored in your app. go to http://appengine.google.com and manually do it. easy for less than 2000-5000 entity.
This question addressed the same topic. There is no one command way to drop an entire datastore's worth of data. The only suggestion I have beyond those give in that previous question, would be to try out the new Mapper functionality, which would make it easy to map over an entire set of entities, deleting them as you went.
