Better explained of my problem with renaming a file in Tomcat
Hi,
I have a servlet, RenameFile, that receives audio file via HTTP Post and
writes it to /tmp/recording.0002002B-0C0022BB-0001.1.20050622.073208.wav.
Then it creates directories under /alert_messages directory based on the
timing parameters that it get. Finally, it renames the
/tmp/recording.0002002B-0C0022BB-0001.1.20050622.073208.wav file to
/alert_messages/2005/06/22/22/00/79_0_200506222200_001.WAV. RenameFile runs
fine when it runs by itself (ONLY one Tomcat, jakarta-tomcat-4.1.30, is
running). However, RenameFile fails to rename the /tmp/recording.0002002B-0C0022BB-0001.1.20050622.073208.wav to
/alert_messages/2005/06/22/22/00/79_0_200506222200_001.WAV when it runs
in a Linux box that jboss-3.2.1_tomcat-4.1.24 is also running. In this box,
TWO versions of Tomcat are running at the same time. I set the
/alert_messages directory with “chmod –R 777” and run jakarta-tomcat-4.1.30
as tomcat user. RenameFile fails the rename operation. But, it creates the
/alert_messages/2005/06/22/22/00/ directories.
It seem like RenameFile can create directory but can’t create file in the
/alert_messages directory when both version of tomcats are running at the
same time. Can it be due to both the jakarta-tomcat-4.1.30 and the
jboss-3.2.1_tomcat-4.1.24 versions are running at the same time in one
Linux box? Can this be Jboss prevented the operation?
Any help in this issue is greatly appreciated.
Debug listing from the RenameFile;
- originalFilename: recording.0002002B-0C0022BB-0001.1.20050622.073208.wav
- file.toString(): /tmp/recording.0002002B-0C0022BB-0001.1.20050622.073208.wav
- file.getName(): recording.0002002B-0C0022BB-0001.1.20050622.073208.wav
- file.length(): 122986
- file /alert_messages/2005/06/22/22/00/79_0_200506222200_001.WAV
- file NOT renamed /alert_messages/2005/06/22/22/00/79_0_200506222200_001.WAV
File Listing in the /tmp directory create by RenameFile;

I should have read your post better and realized there was no Java
method for RenameFile as that is what I wrongly assumed... How exactly
are you ceating the directories and trying to move the file?
Are both servers running the same servlet and doing similar things?

Hi,
Thank to stdunbar for pointing out the problem that I was having. It turns out that the /tmp and the /alert_messages ware mounted on two different nodes in the file system. After changing the directory for writing the temporary audio file to be the same as the /alert_messages directory. The problem goes away.
/dev/sda11 497829 27391 444736 6% /tmp
/dev/sda7 1011928 217304 743220 23% /
Thank Jason for his help.

The other version of tomcat ( jboss-3.2.1_tomcat-4.1.24) is embedded in the Jboss. This version of tomcat does not contais the servlet named RenameFile. A color coded of the java class that does the renaming of the file is listed in the following site:
