Hi, I try to install and test logstash according to the following tutorial. [https://www.elastic.co/guide/en/logstash/current/first-event.html](https://www.elastic.co/guide/en/logstash/current/first-event.html) I have the following error. java -version java version "1.8.0\_31" Java(TM) SE Runtime Environment (build 1.8.0\_31-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode) or java version "1.7.0\_75" Java(TM) SE Runtime Environment (build 1.7.0\_75-b13) Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode) cd logstash-1.5.4 .\bin\logstash -e 'input { stdin { } } output { stdout {} }' Erreur : impossible de trouver ou charger la classe principale org.jruby.Main Could you help to understand the problem and solve it ? Best regards, Franck ---

> [@Franck\_Serot](#): > > input { stdi { } } output { stdout {} } Is that a typo, it should be `stdin`. ---

No it's not the problem because I tested with stdin instead of stdi. ---

I think the problem is jruby because I can't get version of jruby. D:\bin\logstash-1.5.4\>.\vendor\jruby\bin\jruby -v Erreur : impossible de trouver ou charger la classe principale org.jruby.Main ---

Shouldn't matter as LS only needs java installed. ---

I find the solution of this problem. set SCRIPT\_DIR=%~dp0 set JRUBY\_HOME=%SCRIPT\_DIR%\logstash-1.5.4\vendor\jruby logstash-1.5.4\bin\logstash -e 'input { stdin { } } output { stdout {} }' ---

Where did you set those variables? ---

Forget my question, I see you set them just before starting logstash on the command line ☹ ---

What's the full path to the Logstash binary? There has been issues in the past when directory names have spaces in them. ---

I installed elasticsearch, logstash and kibana in the following directories. Then, I created 2 files : - logstash.cong, logstash configuration file - start.bat, a bat file who start elasticsearch, logbash and kibana I think ELK could be started like services but i dont't test this method for the moment. D:\bin\elk\elasticsearch-1.7.2 D:\bin\elk\logstash-1.5.4 D:\bin\elk\kibana-4.1.2-windows D:\bin\elk\logstash.conf input { stdin { } } output { elasticsearch { host =\> localhost } } D:\bin\elk\start.bat @echo off set SCRIPT\_DIR=%~dp0 set JRUBY\_HOME=%SCRIPT\_DIR%\logstash-1.5.4\vendor\jruby start elasticsearch-1.7.2\bin\elasticsearch.bat SLEEP 10 REM logstash-1.5.4\bin\logstash -e 'input { stdin { } } output { stdout {} }' start logstash-1.5.4\bin\logstash -f logstash.conf SLEEP 10 start kibana-4.1.2-windows\bin\kibana.bat SLEEP 10 ---

You are in the wrong folder ... that's why you have to set the JRUBY\_HOME Since you are working under Windows you have to use the bat file ``` cd D:\bin\elk\logstash-1.5.4 bin\logstash.bat --e 'input { stdin { } } output { stdout { codec => "rubydebug" } }' ``` ---

No, I had the same problem with cd D:\bin\elk\logstash-1.5.4 \bin\logstash -e 'input { stdin { } } output { stdout {} }' And I solved it with cd D:\bin\elk\logstash-1.5.4 set JRUBY\_HOME=D:\bin\elk\logstash-1.5.4\vendor\jruby \bin\logstash -e 'input { stdin { } } output { stdout {} }' I created then a directory elk in order to group the directories elastisearch, logstash and kibana. The file start.file is just a script to start quickly the 3 applications. ---
