Windows xp and java.exe problem

Question

Hello all..
I tried to execute have a batch file consisting a jar file and classes in windows xp platform. I used j2sdk1.4.0_03. All my classes are stored in : C:\MyDocument\Softwares\classes directory
and the jar files are in: C:\MyDocument\Softwares.
I wrote the following commands in the batch file:
java -classpath C:\MyDocument\Softwares\classes;
C:\MyDocument\Softwares\jexcelapi.jar mainClass
When I lauched that batch file, a message came out:
java.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
Could you tell me where the problem is and why? Do I need windows xp patch to eliminate the problem? And where can I find that patch?
Thanx for any suggestions...
Richard

Thanks for your comments. I have tried to reinstall the J2SDK, but then another error message appeared:
Error occured during the initialization of VM
java/lang/NoClassDefFoundError:java/lang/Object
I've checked my Path and it's set as following:
C:\j2sdk1.4.0_03\bin;
and my classpath setting:
C:\MyDocument\Softwares;C:\MyDocument\Softwares\classes;C:\j2sdk1.4.0_03\lib;
When I tried to execute the java command in any directory (inclusively in C:\MyDocument\Softwares) I always got that message. The only directory where I was able to run the command is in C:\j2sdk1.4.0_03\bin;
Before I did the reinstallation, I never had such a problem.
Have any hits? Thanks in advance..
