Hi!

I'm having some problems getting Tomcat to work on my gentoo installation. Whenever I try to launch it using startup.sh it says that it has started successfully but logs do not say the same :P
I have tried some googling and some searching in this forum but couln't come up with a solution.
Here is my log:
Code:

It looks like the servlet api is missing but dev-java/tomcat-servlet-api is installed in my system.

Any ideas?

Thanks in advance :D

Why you not start tomcat with /etc/init.d/tomcat-9 ?

I had already read that thread before, it helped me placing the config and init files where they should be but couldn't get it fully working though.
Thank you very much anyway :)

Don't know if this is the answer but seems similar to your problem


https://qiita.com/tkprof/items/d71af7899c9df96444cc

Quote:
with running Tomcat 7 and Tomcat 8 with same conf/ files, the change has been made as following:

http://tomcat.apache.org/tomcat-8.0-doc/changelog.html

55620: Enable Tomcat to start when either $CATALINA_HOME and/or $CATALINA_BASE contains a comma character. Prevent Tomcat from starting when $CATALINA_HOME and/or $CATALINA_BASE contains a semi-colon on Windows. Prevent Tomcat from starting when $CATALINA_HOME and/or $CATALINA_BASE contains a colon on inux/FreeBSD/etc.`

now running OK both 7 and 8


Edit to add: also this although it's from tomcat 7

Finally found it!

In the file /usr/share/tomcat-9/package.env the servlet jar file was not appearing inside the CLASSPATH variable. Added its location and now it works perfectly!

Thank you all very much :D

Thank you, I had the same problem, that also fixed it.

However, I'm not sure this is the right place to fix it, as this file gets overwritten after every update of the package. Therefore, I raised a bug:
