Hi All,
New to Elastic but not having a good start. Have managed to get Metricbeat working and reporting into out Cloud instance, now need to get Logstash working so I can run some SQL querys against a DB.
Have gone through the config setting etc as per set-up pages ([https://www.elastic.co/guide/en/beats/libbeat/5.4/logstash-installation.html#\_starting\_logstash](https://www.elastic.co/guide/en/beats/libbeat/5.4/logstash-installation.html#_starting_logstash)) but when attempting to start I get the error in the title: Error: Could not find or load main class Files\Microsoft.
Have read through and attempted fix as outlined here: [Error: Could not find or load main class Files\Microsoft](https://discuss.elastic.co/t/error-could-not-find-or-load-main-class-files-microsoft/163841) but has not resolved my issue.
Have checked a few other related post, but non of the suggested fixes have worked for me either.
Useful info:
Logstash version: 7.3.2
Java\_Home: C:\Program Files\Java\jdk1.8.0\_221
CLASSPATH: .;"C:\Program Files\Microsoft JDBC Driver 4.2 for SQL Server\sqljdbc\_4.2\enu\jre8\sqljdbc42.jar";"C:\Program Files\Java\jre1.8.0\_221\bin\java.exe"
java version "1.8.0\_221"
Java(TM) SE Runtime Environment (build 1.8.0\_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)
Appreciate any assistance that can be provided to get this working, thanks
