Hi,
I am using Struts 1.1 with iPlanet 6.1 on Solaris Platform.
I have a form with a textarea and in my action when I get the data entered in the form and log it to the log file. But when i do a vi on the logfile for every newline entry in the textarea I see a control-M characters like below

Text entered in the Textarea
---------------------------
testing steps:^M
1. Login^M
2.Click on Monitoring link^M
3. Verify contents and logout^M

Text in the log file
--------------------
testing steps:^M
1. Login^M
2.Click on Monitoring link^M
3. Verify contents and logout^M

From where is this controm-M characters appearing?
Please help.
