LONG STORY SHORT "Could not find the main class: main. Program will exit."

Hi guys, first post, not the best way to join a forum haha.
So here it is, when I ran the batch file, it instantly closed and nothing happened, so I go to look what went wrong....

I should probably note ahead of time that I changed the batch file from saying
"java -Xms512M -Xmx512M -classpath"
to
"C:\WINDOWS\SysWOW64\java -Xms512M -Xmx512M -classpath"
Because vista is retarded like that.

According to cmd this failed in my face:
C:\Users\*****\cd desktop

C:\Users\*****\Desktop>cd womclient-1.3

C:\Users\*****\Desktop\womclient-1.3>run.bat
