Server Utilities :: Can't Read Bad File From Java Code

We are using sqlldr query to load data into a table. This is handled in a java code. We are uploading an xls file which gets converted into csv and then the sqlloader call works, which in turn creates a bad and log file for error messages.

But I am not able to locate the bad file(in filesystem) within java code.

Below piece of used.

File file =new File(destfilePath);
if(file.exists()){
FileReader fr = new FileReader(file);
LineNumberReader lnr = new LineNumberReader(fr);
linenumber=0;

[code]....

The above code is able to locate CSV ,but not the bad file(whereas both files created in same path).
