Re: problem with local variable-please help me

sometimes the compiler (or other code generator) produces debugging info 
like variable names (like when -g is specified), and sometimes it 
doesn't.  When it doesn't, it would seem that bcel tells you bogus 
names.  You can use javap to see what kind of debugging information is 
included in a particular class.

basically, in a lot of cases, you'll just be out of luck if you want 
local variable names.
