Execution problem of java executable

hi,

In simple i have a java .jar file under c:\program files\ which is a java executable file. Now i am trying to execute the file using double click on it. it is producing "Exception in thread "main" java.lang.NoClassDefFoundError:"

If i put the file under any directory where no white space is occuring with in the file path then it is working fine. How can I run my program. Another think the place of the executable is completely upon the user so please help me with some generalize solution.

thanks in advance.
