Bad Magic Numbers (Any Java Guys Around)

Hi,
I am not sure if this a right place to post my Query, but since lot of OAS Questions have been ansewered Here I am Putting This here.
I have created a applet that runs fine when run from a AppletViewer But if i try to run it from the browser. It gives a ClassFormatError Bad Magic Number.
When i try to look at the Log of the Carridge It says fileNot FoundExcepition.
I do not understand why my servlet should throw that exception. The Cartridge is considering the <filename.jar> as a package.
I have given a Sample of bot my Java COnsole Output and The Log File.
My Console Output Follows

JVM issue with applet - Duplicate Key in Parameter Table - Bad Magic Number

Hey, I have Googled this one to death and have seen a few vague references to this problem, but nothing I can relate back as solution.
I wonder if I need to tell the customer to reinstall the OS and, ultimately, the JRE. I'm just looking for a little guidance on what any of you may think. Am I missing a setting or something?
The user is trying to download an applet with IE with 1.3.1_16 and Firefox 1.07 with the Java Embeded Plug-in.
Even though JRE 1.3.1_16, 1.4.2_09 and 1.5 are all installed and Firefox has the JEP also installed, Firefox still wants to use 1.3.1_16 as does IE. I'm guessing that the JEP didn't work.
They can't use Safari which does seem to be using 1.4.2_09 because their RSA ID won't authenticate through it.
On my machine, when I run with the same OS,browsers, and Java 2 plug-ins, I can successfully load the applet.
This is the error that the user gets in the java console is:
Duplicate key in parameter table: code using the htmlAttribute.
first: com.ibm.eNetwork.HOD.HostOnDemand
second: com.ibm.eNetwork.HOD.HostOnDemand.class
java.lang.ClassFormatError: com/ibm/eNetwork/HOD/HostOnDemand (Bad magic number) at java.lang.ClassLoader.defineClass0(NativeMethod)
at java.lang.ClassLoader.defineClass(ClassLoader.java:488)...
Would you reinstall the OS and Java? or look at another setting? or look at the JEP installation again?
Thank you.

Without reading the full post (sorry for that) my guess is that the applet needed to be fetched through a
proxy, the proxy corrupts the applet because it's signed (finjan is one that does that).
The reason why a proxy would do so is because the default settings of sun jre will ask the user the
"do you trust" question to the user which could result in the user loading an applet that is allowed to do
anything the programmer wants (4us, spyware, nasty stuff).
Try to do the following:
1. create a html file locally with the following content:
rightclick and save target as
2. open the page, right click the link and save the file
3. apen the file with an unzip programm (winzip) and check if the content has changed.
4. If the content has changed than the proxy might have done this, contact the system administrator
It might allso have been done by a firewall installed locally.

[b] bad magic number [/b]

hallo,
first sorry for my bad english but i'm from austria.
i wrote a html-page in which a applet is called using object tag. if i click on this page open it with ie there is no problem, but when i return this page with an servlet i get the following stacktrace:
java.lang.ClassFormatError: spider/view/Graph (Bad magic number)

the client and the server are using jdk1.4 exactly the same cause I reinstalled it on both machines.
Also I recompiled it several times but it doesn't work anyway.
i get the stacktrace on client side. and my html page which the servlet returns is the following:

Java.lang.ClassFormatException : Bad Magic number Excpetion

Hi all
I am trying to hit an applet through an iplanet web connector.
The scenario is machine 1 is the web server (iplanet 4.1) . machine 2 is app
server (iplanet 6.0 sp2)
The web connector is configured for handling all the requests to machine2
that refer to the app server.
when i place my jar (containing the applet classes) on the app server and
then try to open it through a jsp on the app server itself , it
throws a
java.lang.ClassFormatError: com/niit/cliks/te/web/TestingEngine (Bad magic
number)
exception.
But if i try with the same jar file on the web server (the same as running
the app server( - i.e. machine 2 ) the jar works just fine.
can anybody put some light on the issue. I am in a very tight deadline
situation.
thanks and regards
raghav..
PS - the applet is not signed and i don't wish (and plan) to sign it.

Dear friend
But the same class file and jars are working (without any change in the jar) when i put them on the web server which is also on the same machine running the app server.
I may suspect my compiled files but i don't.
i have compiled them at least ten times from the moment i started getting the error.
any other guesses....
thanks for your consideration
regards..

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!
marc

Bad 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?

Are there any magic numbers in credit limits?

Wondering if different credit limits for an individual account, or overall total limit, has any impact on underwriting or on score.
Back when I had under six months of credit history, before I could get a FICO, the FAKO from Amex used to tell me one thing helping my score was "you have built a strong relationship with lenders" which I took to mean I had some high limit cards (I was able to get two based on my Canadian credit, at that time $8000 on an Amex and $11000 on my RBC visa).
Since then I have always wondered whether there are magic numbers in credit limits from a scoring or underwriting perspective.
I hear "high limit" described differently but a common number I hear is a limit over $5000. I hear that over $25000 on an Amex and you may be asked to verify income.
And are there any overall magic numbers? Do you wind up in a different bucket if your overall limit is $50k or $100k?
I know it impacts utilization but is there any other impact? What about fit human underwriting, any common practices there?
Thoughts?

Thoughts?I am not aware of any "magic numbers" for score based solely on credit limit $$$. They scores focus on % of credit utilized. On a side note, some posters have said that high limit cards (either over $35k or $50k) are excluded from card specific utilization calculations. See below table for getting a CL on a new card.

Java.lang.ClassFormatError: AppletSame (Bad magic number)??****

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..

Bad magic number in super-block while trying to open /dev/sda2

hello,
So I've a linux partition, and then I wanted to install a Windows copy. I've only 1 HDD with differents partition into it:
sda5 (swap)
sda6 /user
sda7/var
sda8 / (which contain the boot and root of course)
sda3 /home
sda2 NTFS (windows xp)
So, as I had linux installed before windows, I had to make my sda2 NTFS (87) under my cfdisk. Then, I went to install windows, everything worked fine, windows booted with his boot system, but I had to restore grub with my archlinux live cd:
grub> find /boot/grub/stage1
grub>root (hd0,7)
grub>setup (hd0)
everything worked successfully, my grub loaded till while booting archlinux I got this error:
couldn't find ext2 superblock, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/sda2
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
What I tried is to run the e2fsck -b 8193 /dev/sda2 but right after that, I thought about it, this isn't linux partition so of course, the superblock isn't the same as they are ntfs type from widnows?
I've read on some forum but unfortunately didn't solve my problem, if anyone has any suggestion before I format the NTFS partition, I'd really appreciate it.
best regards, maz

what I think it happened, is that after installing windows your partitions numbers got twisted a bit. What you have to do is to edit /etc/fstab, and check out your linux and swap partitions mounting entries, I believe you just have to change the number of /dev/sda[number] coresponding to your linux partition in fstab
If you can't solve it, post the output of
fdisk -l
and
cat /etc/fstab

This looks to be filesystem corruption. The reason the fsck's don't find anything is they are really _not_ doing any checking. In the filesystem is an unmounted-cleanly flag. This flag is set when the umount(1) is done. If the system were to crash with the filesystem still mounted, this unmounted-cleanly flag would not be set, so the system would consider the filesystem to need checking: no unmounted-cleanly flag, fsck has work to do; unmounted-cleanly flag set means fsck does nothing.
Be sure the filesystem is unmounted all around the cluster before attempting to repair the filesystem.
So do this:
    # fsck.ocfs2 -f /path/to/device/partition
The "-f" switch forces fsck.ocfs2 to ignore the state of the "unounted-cleanly" flag and actually perform its tests.
Does this repair the problem?

Image size and mime type.. non-java guy needs help

Image size, mime type.. non-java guy needs help
Im not at all familiar with java so this is really weird for me to work out. I?ve been doing it all day (and half of yesterday).
Im trying to write a custom clodFusion tag in java that gets the width, height, size and MIME types of a given file. I?ve been trying to get it to work on the command line first. I can get the width and height but cant get the size and the MIME type.
Here is what I got
/*import com.allaire.cfx.*;*/
import java.awt.image.renderable.*;
import javax.media.jai.*;
import com.sun.media.jai.codec.*;
import java.io.*;
import java.util.*;
public class ImageInfo {
private RenderedOp image = null;
private RenderedOp result = null;
private int height = 0;
private int width = 0;
private String type = "";
private String size = "";
public void loadf(String file) throws IOException
file = "80by80.jpg";
FileSeekableStream fss = new FileSeekableStream(file);
image = JAI.create("stream", fss);
height = image.getHeight();
width = image.getWidth();
System.out.println(height + "\n");
System.out.println(width);
System.out.println(type);
public static void main(String[] args) throws IOException {
ImageInfo test = new ImageInfo();
test.loadf(args[0]);
can anyone please help me out to modify the above so I can also print the mime type and the file size to screen.
thanks for any help

any suggestions?

Bad magic number

I have an applet that i am trying to load in a JSP
<applet name="MyTestApplet" code="mypackage.MyTestApplet.class" >
</applet>
mypackage/MyTestApplet.class is under the approot/pages directory and the jsp is also in the same directory.
whenever the jsp is called and applet does not get inited and the error i see is a ClassFormatError: Bad magic number
Please help.. this is extremely urgent.
Thanks in advance for any input anyone may have.
The appserver i am using is SunONE

First the <applet tag is depreciated, you should use <object instead (w3c has depreciated applet for quite
some time now).
When I see the tag you don't use a jar package (archive is missing) so let's pretend the url to your page is
http://mysite/mypage.jsp
the mypage.jsp contains the applet so the url to the applet is:
http://mysite/mypackage/MyTestApplet.class
can you download the file using a browser?
you can do this by saving the following line in a html file and right click it then sava target
right click and save target as
After downloading is the file the same as the file on the web server?
The reason I ask this is because I got the bad magic number when a jar was loaded through a proxy.
The proxy did something with the jar file making it corrupt. I think your problem has something to do with
the way your web server is serving the applet or (proxy) something between the client and the server.

Is there any java API throgh which My program can get harddisk,cpu ID adres

hello
Is there any java api throuh which i can get hard disk and processor serial numbers.
i have already use
process p=Runtime.getTime().exec("cmd command");
please other than this send any java api, progamming technique that remain same on all plate forms
advance thanks
best regards

i have already use ..>1) What business is that information to your app.? Or to put that another way. Why do you want to know?
2) Those words are 'Java', 'API' and 'I' (which is always upper case).
3) One upper case letter should be used at the start of each sentence, not just once at the start of a post.

Sun Ultra 25 - Bad magic number in disk label

I have a Sun Ultra 25 SPARC that is booting fine to it's 80GB SATA drive. Solaris 10, OpenBoot 4.22.19.
Here's what I did:
I installed a 2TB Western Digital SATA drive into the HDD1 slot.
I formatted the disk in the HDD1 slot via the format command, labeled the disk, and divided it into partitions.
I then used newfs to build the ufs on all partitions.
I mirrored the disk in HDD0 to the disk in HDD1 using ufsdump for all partitions. The data is accessible and looks ok.
After this was done I did an installboot to /dev/rdsk/c1t1d0s0 (the / partition of the HDD1 slot).
I then did a fsck on every partition to verify that they are okay.
I then took the hard drive in HDD1 and put it in the HDD0 slot, now wanting to boot off that disk.
At the reboot:
Bad magic number in disk label
Can't open disk label package
If I do a probe-scsi:
MPT Version 1.05, Firmware Version 1.08.03.00
Target 0
Unit 0 Disk ATA WDC WD20EADS-00R0A01 3907029168 Bocks, 2000 GB SATA device PhyNum 0
As far as I can tell disk0 is the correct devalias which is:
/pci@1e,600000/pci@0/pci@9/pci@0/scsi@1/disk@0,0
I just don't understand how the fsck is okay, but the boot give bad magic number in disk label?
The 80GB drive in HDD slot 0 works fine with the boot disk0 command, all I'm doing is swapping a larger disk with the same data for the smaller disk.

if it is like any other Sun product, it needs to go through the format command and get a volname.... it is just a label, but it needs to be done.
