Failed to start gerrit under tomcat - 'Error filterStart'

[BenNiu Ji]

Hi, all

I'm trying to deploy gerrit under tomcat. But after putting the war under webapps and restart the tomcat, gerrit can no longer be accessed. The return code is 404.

I checked the log, it was saying "SEVERE: Error filterStart" and "SEVERE: Context [/gerrit] startup failed due to previous errors".

Does anyone know why this happened and any solutions?

Thank you!

What version of Gerrit?

There was a bug with the plugin system that caused a plugin to "steal"
the web context from Gerrit and thus Gerrit's content disappeared from
the web space when a plugin loaded, e.g. the replication plugin.

Thanks, Shawn. I'm using gerrit 2.7

OK, its not what I was thinking about, because that issue was fixed in 2.7:

Fix Gerrit plugins under Tomcat by avoiding Guice static filter

The static GuiceFilter breaks when a plugin loads and configures
its own web environment. Follow the pattern used by JettyServer
to initialize and load GuiceFilter in a non-static way, allowing
Gerrit to always have its own filter stack during any request.

Its probably a misconfiguration in gerrit.config. Unfortunately the
exception was lost. Tomcat felt it was necessary to log the SEVERE
Error filterStart but did not bother to include the cause of this. It
then later complained we didn't shutdown correctly, which I can
understand because startup didn't go correctly so the application
didn't finish tracking the threads it created.

Does gerrit daemon start on its own?
Is there a problem with the datasource context being passed from
Tomcat to Gerrit for the database access?

Thanks Shawn. It finally works after I copied all jars under '$site_path'/lib into tomcat's lib.
