None I have a simple "Hello World" midlet. I can compile the midlet fine but while running it I un into the error ALERT: java/lang/ClassFormatError: Bad version information.Attached is the console output.I am using WTK 2.2 and JDK 1.6 u2. I created this project as J2ME project with a single J2ME module. Just not sure what am I missing. The same thing works in NetBenas but NB is just not as much pleasure as Selena.Attachment(s):IdeaError.txt Facebook Twitter LinkedIn Google+ Date Votes 17 comments 0 Vinay Moharil August 03, 2007 04:21 Looks like I got the problem resolved but now I am running into another issue:I cannot call any static method on another class in the same package. All the classes in the package are public and all the methods in that class are public. It cannot find the class itself. But this happens only during module build - the editor shows all fine and is even able to do auto-complete etc.This is becoming just too painful to develop J2ME with IntelliJ. NB just seems to work right out of the box. 0 Vinay Moharil August 03, 2007 04:53 I think I found a work around but it's just wackythis is the code I have that does not workpublic class SomeClass{ public static void doSome() { InputStream is = SomeClass.class.getResourceAsStream("someFile"); }}this code workspublic class SomeClass{ public static void doSome() { InputStream is = new SomeClass().getClass().getResourceAsStream("someFile"); }}For another class' static method I had to do the same - create an instance and then call an instance method that calls the static method.Looks like something very basic wrong??? 0 Anna Kozlova August 03, 2007 12:14 Hello Vinay,Could you please provide "build" output as well as project example cause it works fine for meThank you-Anna KozlovaJetBrains Inc.http://www.intellij.com"Develop with pleasure!"Looks like I got the problem resolved but now I am running intoanother issue:I cannot call any static method on another class in the same package.All the classes in the package are public and all the methods in thatclass are public.
