Please provide JAVA_HOME value

3

JAVA_HOME C:\Program Files\Java\jdk1.8.0_45

This log shows
Error: Could not find or load main class Files\Java\jdk1.7.0_51\lib;D:\PageSizeT
your java pointed to different location. Try to fix it by adding
JAVA_HOME=C:\Program Files\Java\jdk1.8.0_45
in your logstash.sh or logstash.bat file (after initial comment section)

5

I don't see any comment section when i try to check in the logstash.bat file.
could you please clarify.

6 
@echo off
setlocal enabledelayedexpansion
set params='%*

My bad I am regerring to sh file instead of bat.

Add after 2 line or at 1 line. any location is fine I believe

7

i did add it in the bat file. i see the below error -
'JAVA_HOME' is not recognized as an internal or external command,

any leads?
thanks

8

set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_45

9

we have upgraded our jdk to below and updated the same in the bat file but still get the same error -
set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_161

10

Is it still pointing to Java 7?

11

we are not using Java 8
jdk1.8.0_161

12

I mean this error

Error: Could not find or load main class Files\Java\jdk1.7.0_51\lib;D:\PageSizeT
ool\Cla

13

yes, still it says the same, jdk 1.7...

14

Then something wrong with your Java environment variables.

15

run java -version from command line.

16

it got resolved now. it was due to CLASSPATH, not sure why but it was referring to that path
