Reason for edit:: Please use code tags

And what this the error message ?
With the line number
and if it is at line 185 it is because the file is not there

and indent your code properly.... how can you expect us to read code like

try {
br = new BufferedReader(
new FileReader("Log.txt"));

A compiler can, you are exhausting me

So the file is not there... I seriously doubt there is a problem with the constructor of FileReader() in Java run time library. This constructor must be called a few thousand times every second over the planet without problem.

Post an output of your directory in Windows or ls on Unix where both your Enquiry.class and Log.txt should be

I already put the enquiry.class and log.txt into one folder but still come out with an error. and I also rename that log.txt file with another name but still failed.

asked you about a DIR or ls output of where your .class and .txt file are

and the stack output error

I already fix the directory error, by put the right directory "C:/Documents and Settings/User/My Documents/NetBeansProjects/Project/Project/src/Log.txt" but when compile or run the GUI2 the data from text file still cannot load to jtable..but there is no error show...you can refer it in the attachment picture of my Netbean screen shot
