I'm developing a J2ME client that must upload a file to a Servlet using HTTP. The servlet part is covered using Apache Commons FileUpload protected void doPost(HttpServletRequest request, HttpServletResponse response) { ServletFileUpload upload = new ServletFileUpload(); upload.setSizeMax(1000000); File fileItems = upload.parseRequest(request); // Process the uploaded items Iterator iter = fileItems.iterator(); while (iter.hasNext()) { FileItem item = (FileItem) iter.next(); File file = new File("\files\\"+item.getName()); item.write(file); } } Commons Upload seems to be able to upload only

Coming from J2ME programming are there any similarities that would make it easy to adapt to Android API . Or is Android API completely different from the J2ME way of programming mobile apps. Alexandre Hauser Actually the Android API is much more powerful than the J2ME. It is much easier to create an application for the Android. Using the J2ME you are limited to simple forms due to the absent of swing-like libraries (though now there exists a library called LWUIT, avoiding the need to recreate from scratch a swing-like library). In Android you will be able to create complex form very quickly,

I have very little idea about mobile platforms, though I am interested to program for them. Would you please compare J2ME VS Android VS iPhone VS Symbian VS Windows CE . I would like to know: which one is better which one should I choose and why if there is any VM technology to test the programs is there any IDE, debugging facilities? Personally, I would like to code for open source, but any suggestions are welcome. I have preliminary knowledge on Java. I would also like to know, if there is anything else that you can recommend. Jeremy Logan There's several of these questions floating around

What mobile platform should I start learning? What matters is: ease popularity of the platform low cost of the SDK and actual handheld MicTech I think 3-4 platforms have a future. But it depends on what platform do you like and how you like freedom in distributing your applications :) Windows Phone 7 .NET and Silverlight through Windows Phone Marketplace Android Java through Android Market (fees) or like normal applications iPhone Objective-C or Java ( Developing iPhone Applications using Java ) through iPhone Market pay some fees ($99/year) The Incredible App Store Hype You need Mac (Mac OS)

I am beginning in java (I'm learning in microedition) and I got this error: "int cannot be dereferenced" in the following class: class DCanvas extends Canvas{ public DCanvas(){ } public void drawString(String str, int x, int y, int r, int g, int b){ g.setColor(r, g, b); //The error is here g.drawString(str, x, y, 0); //and here } public void paint(Graphics g){ g.setColor(100, 100, 220); g.fillRect(0, 0, getWidth(), getHeight()); } } What am I doing wrong here? Well I came from PHP and ECMAScripts where I was able to pass my function arguments this way so I really don't understand this error.
