Open a file

[nisha Sham]

How can I Open a Word or Excel or any other file using java application

[rajarajan]

use can use the process class.
eg. Process p = Runtime.getRuntime().exec("<executble file name iec:\word.exe>","<document file name>");
The process class is the best way to invoke a file from word. Like this u can use the same class to call any exe file.
real eg:
Process p = Runtime.getRuntime().exec("c:\word.exe","test.doc");

I tried this
Process p = Runtime.getRuntime().exec("E:\Program Files\Microsoft Office\Office\winword.exe","test.doc");
and I get an Illegal escape character
Do you have an idea?

Younes,
Try
Process p = Runtime.getRuntime().exec("E:\\Program Files\\Microsoft Office\\Office\\winword.exe","test.doc");
It still won't work. Can you figure out why?

If all you want to do is open and read/write a file then you can use the FileReader and FileWriter classes.

Hi,
I tried doing :
Runtime.getRuntime().exec("C:\\Program Files\\Microsoft Office\\Office\\winword.exe C:\\hello.doc");
and it works. The hello.doc has to be there already existing.
Can someone throw some light on :
(a) How to use the .exec(String, String[]) version. ( name, value pair thing mentioned in javadoc is confusing )
(b) How to create a new document ( ie when hello.doc is not existing )
