Re: Permissions problem

I would do a recursive chown, but some of my files need to have different permissions so that the mod_jk2 connector will work... Specifically, the jk2.socket and jk2.shm files. I have done recursive chown on other locations though, and it still doesn't seem to do it... 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:

java.io.FileNotFoundException: /files1951663148 (Permission denied) at java.io.FileOutputStream.open(Native Method) at java.io.FileOutputStream.<init>(FileOutputStream.java:196) at java.io.FileOutputStream.<init>(FileOutputStream.java:151) at java.io.FileWriter.<init>(FileWriter.java:93) at org.apache.tools.ant.taskdefs.compilers.DefaultCompilerAdapter.executeExternalCompile(DefaultCompilerAdapter.java:420)

  at org.apache.tools.ant.taskdefs.compilers.Jikes.execute(Jikes.java:232)
  at org.apache.tools.ant.taskdefs.Javac.compile(Javac.java:842)
  at org.apache.tools.ant.taskdefs.Javac.execute(Javac.java:682)
  at org.apache.jasper.compiler.Compiler.generateClass(Compiler.java:320)
  at org.apache.jasper.compiler.Compiler.compile(Compiler.java:370)

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).

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
