Re: Permissions problem

[Brian Brewer]

Have you recently switched to using Jikes as your compiler?  If so, 
jikes is probably running as root or some other user and cannot save its 
temporary files within the tomcat folder structure.  Try adding 
whichever user jikes runs under to the tomcat group and make sure the 
tomcat folder is +rw for both the tomcat user and the tomcat group.

Good Luck!

Also, this problem occurs after tomcat has started completely, when 
the first jsp page is trying to be compiled. It could be a syslog 
(com.protomatter.syslog) thing trying to write somewhere, or maybe an 
oscache (opensymphony) thing, but I don't think so. The error 
specifically says:

So I think it has to be a compilation thing, not a syslog or oscache 
thing.

Any ideas of how to find out exactly what this is? Who has the source 
and can look at 
org.apache.tools.ant.taskdefs.compilers.DefaultCompilerAdapter.java:420?

Daniel,

Do a chown -R tomcat (tomcat base directory) to set the owner to 
tomcat for
all the directories and files under the tomcat directory. When tomcat 
starts
it sets up temp file that are cleared and recreate. The error is 
saying that
tomcat can't because the write permission on the directory is wrong. 
Most
likely root owns the directory at this point. I believe default is in 
the
root of the tomcat directory (jakarta-tomcat-x.x.xx).

Subject: Permissions problem

 

I recently upgraded my webapps, and now I am being forced to run tomcat
as root. I'd rather run it as a different user like I used to.
I know that somewhere tomcat is having a permissions problem reading or
writing something, but it is very hard for me to decipher what I 
need to
change the rights to... can someone figure it out based on this stack
trace from catalina.out? Specifically I wish I could figure out what 
the
line:
Caused by: java.io.FileNotFoundException: /files1951663148 (Permission
denied)
means. Is it trying to read something or write and what file is it?

Thanks,
Daniel Gibby
