Hello,
I need help. Can anyone recommend me anything which can provide me with the ability to trace a java application.
By the trace, what I really mean to say is some sort of a log that shows which object sends message to another object and which object instantiates another object.
I will be really gratefull and thank you very much in advance
regards
Tauseef
I guess you basically need a LogManager class
which writes the msgs in a log file
but you have to call its methods in your other objects for whatever msg you intend to write into a log file
something like
import java.io.*;
public class MyLogManager {
FileOutputStream fout;
public MyLogManager() throws Exception{
FileWriter fout = new FileWriter("mylogfile");
}
public void log( String message) {
StringBuffer theBuf = new StringBuffer();
try {
// may put time here
theBuf.append(' ');
theBuf.append(':');
theBuf.append(message);
writeMsg(theBuf.toString());
} //end try
catch (Exception ex) {
ex.printStackTrace();
}
}
private void writeMsg(String str) throws Exception{
fout.write(str.getBytes());
}
}
Please modify this code to your requirements
