Hi,
U guys miss understood my question. I want with out using any
decompiler(they use reverse enginnering I guess). I have source code
and bytecode I want to know for a specific instruction in the
instruction list the corresponding source code. For example we can
know the line number of a instruction in the source code by using
LinenumberTable. Can we get exact position in the line which has
produced the instruction.
For example
if( (a!=0 && b> 40) || (b!=a && c==d) && (c>=78 || d<40))
//* 8 14:iload_1
//* 9 15:ifeq 24
//* 10 18:iload_2
//* 11 19:bipush 40
//* 12 21:icmpgt 48
//* 13 24:iload_2
//* 14 25:iload_1
//* 15 26:icmpeq 59
//* 16 29:iload_3
//* 17 30:iload 4
//* 18 32:icmpne 59
//* 19 35:iload_3
//* 20 36:bipush 78
//* 21 38:icmpge 48
//* 22 41:iload 4
//* 23 43:bipush 40
//* 24 45:icmpge 59
instructions
//* 10 18:iload_2
//* 11 19:bipush 40
//* 12 21:icmpgt 48
are being generated for b > 40. How can I say this from bytecode is
there any facility in BCEL to tell the offset in the line for specific
instruction.
thanks inadvance
Bye
