Exist: eXist-4.6.0 YAJSW service fails to start because of moved classes

[jonjhallettuob]

What is the problem

The eXist-db service installed by installDaemon.sh doesn't start in 4.6.0. It appears that some critical YAJSW classes have moved, but the YAJSW wrapper.conf still points to the old location.

For example, when I install eXist-db 4.6.0 using the Puppet module, the eXist-db service fails to start, and the YAJSW log says

INFO|18118/0|Service eXist-db|19-02-22 09:35:51|error finding main method in class: org.exist.yajsw.Main : org.exist.yajsw.Main
INFO|18118/0|Service eXist-db|19-02-22 09:35:51|java.lang.ClassNotFoundException: org.exist.yajsw.Main
INFO|18118/0|Service eXist-db|19-02-22 09:35:51|no java main method found -> aborting

The error appears to be because org.exist.yajsw.Main has moved from /usr/local/existdb/tools/yajsw/classes in 4.4.0 to /usr/local/existdb/tools/yajsw/target/classes in 4.6.0, but the wrapper.conf still references the old path.

If I add /usr/local/existdb/tools/yajsw/target/classes to the classpath list in /usr/local/existdb/tools/yajsw/conf/wrapper.conf, the service starts as expected.

What did you expect

I expected the eXist-db service installed by installDaemon.sh to start.

Describe how to reproduce or add a test

Install Vagrant and VirtualBox then

git clone https://github.com/mpese/vagrant-exist
cd vagrant-exist
echo "existdb::exist_revision: 'eXist-4.6.0'" >>control/hieradata/common.yaml
vagrant up
vagrant ssh
sudo -i
ps -ef | grep java

You'll see YAJSW attempt to start eXist-db but fail, with errors in /usr/local/exist/tools/yajsw/logs/wrapper.log.

Hi,
A PR has been created and accepted after release of 4.6.0; I hope 4.6.1 will be released anytime soon.

see https://github.com/eXist-db/exist/pulls?utf8=%E2%9C%93&q=is%3Apr+is%3Aclosed+location+yajsw+classes+

So sorry, not sure how I managed to close this!

Brilliant, thanks! In that case, I'll wait for 4.6.1...
