Javassist Usage, pros & Cons

[vanisree]

Hi Team,

I am searching for the tool,which gives the data of the method args during runtime.
I had thought javassist(byte Code manipulation tool) is one tool through which we can change the implementation of a class at runtime.
can it give the data/value of the method args during runtime.
suppose my class is like this,
Class1{
mthdA(int a) {syso("Val of A"+a);}
main(String args[]){
int b=3;
mthdA(b);
}
}
In the above class can i hack the value of "a"
can anyone suggest any other tool by which we can get the data/value of the method args during runtime.
Along with can anyone give the info/. about "javassist".

Thanks in advance

Eclipse can do it, why reinvent the wheel?

ps. your code doesn't even compile ...

Hi Jos,

can you give me some info, on how to get the dynamic data during runtime.
while debugging we will be getting the method args data rite,i need that data.
will javassist give that data( it seems javassist will give the class infor/. and the methods ,args names only(my assumption)).
is there any tool to crack that data.

Thanks in advance
