problem with local variable-please help me

Hi,
i have a problem to get the name of the local variable in a method.
i used LocalVariableTable and LocalVariable[] in this context:

             ConstantPoolGen cp = mg.getConstantPool();
       InstructionList il = mg.getInstructionList();
       InstructionList iL = new InstructionList();
       InstructionHandle[] ih = il.getInstructionHandles();
       Instruction[] inst = il.getInstructions();
                          .
                          .
                          .

              LocalVariableTable  lt = mg.getLocalVariableTable(cp);
           LocalVariable[] lv = lt.getLocalVariableTable();
       for(int t=0; t<lv.length; t++){                    
if(lv[t].getName().equals( varNameSpec) && lv[t].getIndex() == 
((LocalVariableInstruction)inst[j]).getIndex()){  



}
But in certain case this stament is good but in another they return 
only  arg0, arg1 who represent the parameters(depend of the number of 
parameters) of the method. I used also LocalVariableGen and i have 
thesame problems.


please help me
