Thank you so much.
I am absolutely new to Tomcat on Linux.
I need to figure out what you mean by "user-id under which Tomcat runs".
Every process on Linux is ran by a certain user. With command "ps -ef",
you can list all the processes and users that run them (first column
from left).
You can easily identify Tomcat process by recognizing Java executable,
something like:
tomcat 28710 1 5 10:43 ? 00:00:17
/usr/java/default/bin/java
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=/usr/local/tomcat/conf/logging.properties
-Dorg.apache.el.parser.COERCE_TO_ZERO=false -XX:MaxPermSize=300m
-Xms300m -Xmx400m -Djava.endorsed.dirs=/usr/local/tomcat/endorsed
-classpath :/usr/local/tomcat/bin/bootstrap.jar
-Dcatalina.base=/usr/local/tomcat -Dcatalina.home=/usr/local/tomcat
-Djava.io.tmpdir=/usr/local/tomcat/temp
org.apache.catalina.startup.Bootstrap start
Here you can see that Tomcat server is started as Java application
packed in bootstrap.jar file, invoked by default JVM
(/usr/java/default/bin/java), and ran by user "tomcat". On some system
the user can be "root" or something else.
Now, to go back to the original question: if the user that is running
Tomcat server have privileges to read or write to any directory on the
file system, so will the tomcat web application. (At least if the
security manager is turned off which is default setting.)
