building Tomcat with a third-party library
Hello,
my colleagues just gave me a challenge before I can retire but the problem
is I haven't done anything else than Email/Excel for years, being an
old-school manager. Please be indulgent.
It took hours before I could find the Tomcat source, unzip it, and much
more to understand the magics with ANT which needs Java to run (I was
ashamed to learn that but the Tomcat documentation is well written, thanks).
Here I am blocked, I need to implement a very simple Authenticator relying
on a proprietary Java library.
When adding the import lines for importing this proprietary package, it's
not possible to compile anymore. I get the following errors. From what I
understand, building Tomcat with an additional library would need to add it
somewhere but I was not able to find this in the documentation. Does anyone
have an idea ?
thanks for reading
A.Hubert.

I have tested both methods, and both are working. Thanks a lot for your
help.

As Chris suggested you could use Tomcat's jars as dependencies to build
your own library.
See https://search.maven.org/artifact/org.apache.tomcat/tomcat-catalina
Then put your-library.jar either in yourApp.war#lib or in
$CATALINA_BASE/lib and configure your Authenticator in
yourApp.war#META-INF/context.xml or
$CATALINA_HOME/conf/context.xml/server.xml
See https://tomcat.apache.org/tomcat-9.0-doc/security-howto.html and

If you decide to modify Tomcat's sources directly then you should add your
library to the build classpath.
See
https://github.com/apache/tomcat/blob/386912a93f130078f52e7094be3a730cda742121/build.xml#L214-L221
The sources of com.exane.* are not really needed. You need the classes,
i.e. the jar.

How important is it to build Tomcat *with* your custom library? What if,
instead, you compiled your library separately and used Tomcat as a
(previously-built) dependency?

Where are the source files for com.exane.* to be found?
