I tested this code(copy-paste) in Orion and Tomcat and it works fine. I guess that this is not the full code you are executing since I see not used imports, the jsp without the <h:form> tag and a navigation rule that will never take place. Anyway try to deploy this to Tomcat or another AS to check if it running properly. I have seen ADF application running correct on Tomcat and not on Orion.

In last test, i'm using ktoolbar directly to build and execute midlet and all go ok.
So, My code is not problem.
I suppose that eclipseme corrupt my classes in build process.
SOLUTION:
My radical solution. I use eclipse without eclipseme, and i use ktoolbar to build, run, package, etc...

I use JRE 1.4.2_05! With JRE 1.5 I get a warning and then the JRE switches to his own SAX Parser.
How can I solve this???
GreetsThe error message says that the class file has a bad "magic number." Magic number is the first four bytes of a .class file and in a valid file they should be CA FE BA BE (in hex); "bad magic number" means that the first four bytes are something else and therefore it's not a valid Java .class file.

Java.lang.ClassFormatError: Bad major version number
Hi friends,
I am using JWS2.0(trial version). I have uploaded class files into servlet (and respective packages), every thing was working fine. one fine day i started getting the 404 - file not found error(JWS not yet expired). I uninstalled the jws, j2sdk1.4.0, jre1.4.0 but with no result.
I even formated the system and loaded all again. But still i am getting the same problem.
The servlet is the simple HelloWorld servlet.
Through the SunExample its working fine. But the uploaded servlet is not getting recognised.
Here is the ErrorLog

Hello all,
I'm writing a ClassLoader and the funniest things are happening. If I load a compiled class for the first time after compilation everything is ok. Once I change the class and recompile it, it starts putting out java.lang.ClassFormatError: (Truncated class file). If I alter the changes back to normal and recompile. It works again. Is there some sort of buffer which keeps the once loaded class in memory, even after rebooting?
Please help, I'm at a loss

I use JBoss 3.0.6 and sdk 1.4. In my program, classes are create and load on the fly. Then using Reflection API I called some
methods in the dynamically created class(this class not
write into a file and it is taken as a String variable).
I refferd this url as a guid to write class loader and compiler.(actually same thing i copied
from there and change it's name Pmat1 to StringCompiler)
http://forum.java.sun.com/thread.jsp?thread=347467&forum=4&message=1439418
When I run this as a normal application, it is work well. Then I try to run it in a jboss and it will give the above error.
In here I Wote some EJBs and struts also and i called the methodds in the StringCompiler(Pamat1) class in a EJB. Thilina is
the name of the dynamically created calss and StringCompiler is the class that includes the class loader and compiler methods
as in the above url. qVoiceManagerEJB has a getvxmlString method. Whithin this method
i called required the methods in the String compiler.
Can u some body help me. Thanx in advanced for any help.

Container c = getContentPane();

Could someone please help?
Also, as i'm new to the lang, could anyone just give me a small sample snippet as to how to produce a new frame/window on clicking a button, the new frame in turn having 2 more buttons which on being clicked generate a (distinct) frame each?

Java.lang.ClassFormatError
I have an ejb client application that works fine when deployed manually. I then decided to decided to deploy with Java Web Start, the deployment goes fine but some of the app. functions don't work and return an error on the console. Here is a copy of the error message.

The portion of my code responsible for this is:
final JTextField jtf = new JTextField(termAndYear[1]);
jtf.addKeyListener(new JTextFieldFormat(jtf,4));
jtf.addFocusListener(new java.awt.event.FocusAdapter() {
public void focusGained(FocusEvent e) {
jtf.setCaretPosition(0);
jtf.selectAll();
Apart from that action, the application works just fine. The interesting thing is, this does not happen if I run the application locally using the required jar files. It only happens when deployed with Java Web Start.
I'll appreciate any help. Thankshi,
it looks like the class you want to load is broken. Can you send more information what app server do you use, which jre use this app server, and which java compiler do you use and the exact line were the exception trows. -
Problem with:error: java.lang.ClassFormatError: Truncated class file
Hello, I created an simple applet writing "hello world". Now I would like to add *.class file to my serwer witch I've implemented on microcontroller P89C51RD2BN.
Serwer is programmed with hex file which is created after compiling C source files. In this case I converted .class file to array in C (using hexedit program). When I am (using IE ) browsing my serwer Html site is loading corectly and *.class file is send from serwer also corectly (define arrays are transfered corectly) but applet is not initiated. When I am runnig Java console I can see this:
error: java.lang.ClassFormatError: Truncated class file
When I am runnig the same site with the same class file on my PC everything is ok.
I would be greatfull for any help. Thx. (sorry for my English :P )Not too familiar with native compilation, which I believe you are trying to accomplish here. It would appear that you don't have any problems running your applet, more or less running it after being converted to legacy code. Try the "native methods" forum under "Fundementals/Key Classes", this may be helpful. Sorry for not being too helpful.

Java.lang.classformaterror: invalid index o in localvariabletable
Hi All
I am getting the next error : "java.lang.classformaterror: invalid index o in localvariabletable"l when compiling with aspectj1.1 and jdk 1.5. I have read in some forums that it was a bug uin jdk 1.5Beta; i Wonder if it has been solved or if it is possible to solve t somehow.
Thanks in advance,
GuadalupeHi,
I'm still on Java 1.4.2, but...... the local variable table is basically the "symbolic information" used for debugging purposes only.
As a workaround, you might be able to turn off the debugging information by including "-g:none" in your javac command line switch.
You may need to recompile all classes which give this error.

Java.lang.ClassFormatError: HTML (Bad magic number)
hi,
i have quite a strange problem:
when my applet tries to parse an XML file with SAX (no DTD-validation) i got the following error:
java.lang.ClassFormatError: <HTML> (Bad magic number)
Well i had some problems before with the ClassFormatError but they were because some class-files were corrupt. They were easy to fix because the defecitve class-file was written next to java.lang.ClassFormatError. This time i got the <HTML> expression next to the error. what does this mean?
thnx in advance!
marcBad magic Number. means the first 4 bytes did not equals CAFEBABE (0xCAFEBABE) But why do you see <HTML> after that is beyound me. Can you locate which class is foul and replace it?

ALERT: java/lang/ClassFormatError: Bad version information.
Hi all,
I'm developing a mobile application but I got this error: ALERT: java/lang/ClassFormatError: Bad version information.
I've read all the posts in the forum and searched for other ones with google, but still no luck :-( pls help.
The situation is the following:
IDE: netBeans 6.5
MIDP2.1
CLDC1.1
javac.source=1.3
javac.target=1.3
J2ME web services 1.0 loaded.
The application retrieves tracking data from a .net web service: I've created the stub with the sun official tool included in the WTK (Stub Generator).
When I run the jar with the sun device emulator, the splash screen is loaded but, when I retrieve data from the web service, the application crashes with the error ALERT: java/lang/ClassFormatError: Bad version information. No problem if there's no data to fetch.
Where am I wrong? pls help, thx,
have a i nica day,
MichelaHave you tried JSR172Demo application that is supplied with Netbeans? if yes, did it work?
Instructions on how to obtain this demo app are provided in [Netbeans help|http://i39.tinypic.com/k2h8og.jpg], section Importing Java ME Projects -> Sun Java Wireless Toolkit project -
I run a Japplet(AppletSame.class) ,found this Exception:
java.lang.ClassFormatError: AppletSame (Bad magic number)??****
what does it mean?how can i solve it?hi,
the problem comes if there is some kind of problem with the class file and therefore the JVM cannot read the class file, try recompiling the program..
