Now, I got out of the command prompt and reentered. I didn't set any classpath or anything. I have created a subdir \archive in the C:\ and writing an output file [DetailTower.....doc")into that.
The DetailTower.class is in C:\Detail\ProjectClass dirctory.
Now at,
C:\Detail\ProjectClass\java -classpath . DetailTower "abc"
I am getting this error:-
C:\Detail\ProjectClass>java -classpath . DetailTower "999999"
Exception in thread "main" java.io.FileNotFoundException: c:\archive\DetailTower09-10-2003-06:23:40.doc (The system cannot find the file specified)at java.io.FileOutputStream.open(Native Method)
