The "FAQ/Linux_Unix" page has been changed by KonstantinKolinko: https://wiki.apache.org/tomcat/FAQ/Linux_Unix?action=diff&rev1=11&rev2=12 Comment: Document the effect of using non-GNU version of tar. Correct HTML markup: use headers. 1. [[#Q2|How do I run without an X server and still get graphics?]] 1. [[#Q3|Tomcat dies after I log out!]] 1.

The "tar.gz" files use GNU extensions to the tar file format (as mentioned in "README" file in the download area). You need a GNU-compatible version of `tar` to unpack them. * Learn how to run Tomcat with separate values of `CATALINA_HOME` and `CATALINA_BASE`, as explained in "RUNNING.txt". This will simplify further upgrades and maintenance. + <<Anchor(Q1)>> - <<Anchor(Q1)>>'''When I run ps (on Linux), why do I see my java process a bazillion times!''' + === When I run ps (on Linux), why do I see my java process a bazillion times! === Linux implemented threads as processes. Due to other gory details that is beyond the scope of this FAQ - the ps command doesn't work correctly with respect to threads.

Java on AIX isn't supporting IPv6 properly. Fix by inserting {{{-Djava.net.preferIPv4Stack=true}}} into JAVA_OPTS 2. Your networking configuration is not correct. If you attempt to {{{ping localhost}}} and don't see '''127.0.0.1''' you need to look into your {{{/etc/host.conf}}} (most Unixes/Linux) or {{{/etc/netsvc.conf}}} (AIX) file to ensure that something like ''"hosts = local, bind"'' is present. + <<Anchor(Q6)>> + === Examples web application does not start. A ClassNotFoundException occurs. === + + Go into `webapps/examples/WEB-INF/classes` and check whether the class file mentioned in the error message does exist. + + If you downloaded a tar.gz file and used a non-GNU version of tar (e.g. on Solaris) it may use wrong (truncated) file names on files that are deep in the hierarchy. This occurs silently: there may be no error or warning during unpacking. One place that is known to suffer from this is the examples web application. The workaround is to download a "zip" file instead of a "tar.gz" one.
