I want to deploy Java .war file using Wildfly v24.0.1 on ec2 aws instance.
I am getting this deployment error, and can not fix it:

{"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.\”webapp.war\".INSTALL" => "WFLYSRV0153: Failed to process phase INSTALL of deployment \"webapp.war\"
    Caused by: java.lang.UnsupportedClassVersionError: Failed to link webapp/WebApplication (Module \"deployment.webapp.war\" from Service Module Loader): webapp/WebApplication has been compiled by a more recent version of the      (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0"}}

Any help will be welcomed.

you need to compile to java 8

#

or if jboss has updated version where it supports java 11 then you need to update your server

Can you do a ps and check the java that wildfly is actually using

#

Since it's clearly not using this java version

verbal minnow Feb 22, 2023, 3:31 PM

verbal minnow Feb 22, 2023, 3:33 PM

#

Hm , I suppose I want to use /home/ec2-user/java/jdk-11.0.18/bin

#

Here is the newest java which I installed

vocal salmon Feb 22, 2023, 3:34 PM

#

/usr/java/latest/bin/java -version ?

verbal minnow Feb 22, 2023, 3:34 PM

#

Java(TM) SE Runtime Environment (build 1.8.0_121-b13)

vocal salmon Feb 22, 2023, 3:35 PM

#

Well that's the issue

#

And also echo $JAVA_HOME?

verbal minnow Feb 22, 2023, 3:35 PM

#

/home/ec2-user/java/jdk-11.0.18

#

But the wildfly doesnt use the correct one

#

Right?

vocal salmon Feb 22, 2023, 3:35 PM

#

Yes

#

How is wildfly starting

verbal minnow Feb 22, 2023, 3:36 PM

#

I run ./standalone.sh

#

which is inside the bin

#

wildfly/bin/standalone

vocal salmon Feb 22, 2023, 3:37 PM

#

env | grep java?

verbal minnow Feb 22, 2023, 3:38 PM

JAVA_HOME=/home/ec2-user/java/jdk-11.0.18```

vocal salmon Feb 22, 2023, 3:38 PM

#

which java

verbal minnow Feb 22, 2023, 3:38 PM

#

/usr/bin/java

vocal salmon Feb 22, 2023, 3:38 PM

#

🤔

#

usr bin java version?

#

/usr/bin/java -version

verbal minnow Feb 22, 2023, 3:39 PM

#

That is the one I want to use

vocal salmon Feb 22, 2023, 3:40 PM

#

Yeah

#

You'll have to see how standalone is ending up on the wrong one

#

It will probably have a hierarchy like some env vars, Java on PATH, etc

verbal minnow Feb 22, 2023, 3:42 PM

#

vocal salmon It will probably have a hierarchy like some env vars, Java on PATH, etc

Is it smart thing to do

#

to just copy paste the whole folder

#

into the one that is wildfly using

vocal salmon Feb 22, 2023, 3:42 PM

#

No

verbal minnow Feb 22, 2023, 3:42 PM

#

aka

#

/usr/java/jdk1.8.0_121/bin

#

ok

vocal salmon Feb 22, 2023, 3:43 PM

#

What's in standalone.conf

Stack Overflow

Use custom JRE for Wildfly 10

Can I choose a custom JRE for a Wildfly Application Server with a property like standalone.bat -Djava.jre=<path>

For my project, it is important that I can't change the value of parameter

verbal minnow Feb 22, 2023, 3:46 PM

#JAVA_HOME="/opt/java/jdk"

#

I guess i will have to change it to /home/ec2-user/java/jdk-11.0.18

vocal salmon Feb 22, 2023, 3:50 PM

#

Well it's commented out atm

#

So you will have to uncomment it and set it to your new path

verbal minnow Feb 22, 2023, 3:58 PM

#

vocal salmon So you will have to uncomment it and set it to your new path

I'll try it now

verbal minnow Feb 22, 2023, 4:15 PM

#

vocal salmon So you will have to uncomment it and set it to your new path

Do I have to specify both JAVA_HOME AND JAVA?

#

#
# Specify the location of the Java home directory.  If set then $JAVA will
# be defined to $JAVA_HOME/bin/java, else $JAVA will be "java".
#
JAVA_HOME="/home/ec2-user/java/jdk-11.0.18"

# tell linux glibc how many memory pools can be created that are used by malloc
# MALLOC_ARENA_MAX="5"

#
# Specify the exact Java VM executable to use.

No, same error

verbal minnow Feb 22, 2023, 4:24 PM

#

vocal salmon Why? Still not working?

I changed only standalone.conf

#

Since the server is being run on Linux server
