tomcat5 recommends no packages.

-- no debconf information

I copied .jar files from lib directories of jakarta-taglibs-standard-1.1.2.zip and jsf-1_1_01.zip to /usr/share/tomcat5/common/lib. When starting tomcat5, NullPointerException occurs and the application does not work.

Here is localhost log file.

Can you reproduce it without a security manager?

Can you check if it works with tomcat5.5?

I toggled TOMCAT5_SECURITY to no in /etc/default/tomcat5 and restarted
tomcat5. Now I get similar error.

With tomcat5.5 (didn't change any options), there are no errors, yet it
does not work correctly. It outputs only blank page, size 0, with
content-type of text/plain instead of text/html.

I have found out that tomcat5 throws that exception only if web
application is called "Jsf_Ex01". If I only rename the directory,
application works and no exceptions.

Is it how I called my first JSF app. It is possible tomcat remembered
that name somewhere. If you wish, I can send you relevant files, just
tell me which one(s). I repeated the same example, just with different
name and it works with no errors.

Also, I can purge tomcat5 and reinstall, but I am afraid we would lose
trail of cause.
