Hi,
I am getting the following Exception. I was not able to trace out what the problem could be.
C:\workspace\onDemand\odwekTest\JavaSource\com>javac Test.java

C:\workspace\onDemand\odwekTest\JavaSource\com>dir *.class
08/25/2004 01:03 PM 683 Logon1.class

C:\workspace\onDemand\odwekTest\JavaSource\com>java Test

Exception in thread "main" java.lang.NoClassDefFoundError: Test (wrong name: com

Please let me know if anyone came thru this exception. I have strong feeling that some problem with classpath but I did set the path as well.
Please suggest me
Thanks

hi
i manage to get exatly same stacktrace
in my case i was declearing my class as member of some package and trying to run it as if it is member of default package ( just java <classname> .
i guess same thing happens with you to run it properly simply go one directory back and say 'java com.Test' if Test class is decleared as public in com package it will work.

Before run program : you must set classpath follow this



and Run program like this

>> java com.Test

Your current directory should be in C:\workspace\onDemand\odwekTest\JavaSource\

prompt>java -classpath . com.Test

Your class is in the "com" package.
So you should go back one folder and invoke the java command from that position.

>cd ..
>java com.Test
