Newbie question re "/usr/bin/java/bin/java not found"

[Ken Peirce]

Hi WildFliers,

I am installing WildFly 26 and OpenJDK11 on Ubuntu 22.04 LTS with latest updates. I am trying to create an Elytron credential store.

This command, using a bash shell, results in the error shown.

sudo /opt/wildfly/bin/jboss-cli.sh --connect '/subsystem=elytron/credential-store=defaultCS:add(location=keystore/credentials, relative-to=jboss.server.config.dir, credential-reference={clear-text="{EXT}/usr/bin/wildfly_pass", type="COMMAND"}, create=true)'

/opt/wildfly/bin/jboss-cli.sh: 88: exec: /usr/bin/java/bin/java: not found

echo $JAVA_HOME show it to equal to /usr/bin/java

This same error is thrown for any jboss-cli.sh --connect attempts.

When I run "systemctl status wildfly", I see this:

  wildfly.service - The WildFly Application Server
     Loaded: loaded (/etc/systemd/system/wildfly.service; disabled; vendor pres>
     Active: active (running) since Wed 2024-04-10 09:27:03 EDT; 19s ago

             └─5781 java "-D[Standalone]" -server -Xms2048m -Xmx2048m -XX:Metas>

The vendor preset (not visible here) is set to active

Q1: Is WildFly actually running, or is it disabled?

Q2: Any ideas why this error is being thrown?  

Cheers,

Ken

JAVA_HOME should point to where JDK/JVM is installed not bin directory.  For instance, on my drone I get following result - for any JVM I choose from alternatives.
/usr/bin$ ll | grep java
lrwxrwxrwx  1 root     root        22 paź 13  2020 java -> /etc/alternatives/java*
lrwxrwxrwx  1 root     root        29 lut  9  2021 java2groovy -> /etc/alternatives/java2groovy*
lrwxrwxrwx  1 root     root        23 paź 14  2020 javac -> /etc/alternatives/javac*

In my startup script I read current JDK home with
readlink -f /usr/bin/java | sed -e 's/\/bin\/java//' | sed -e 's/\/jre//'
which currently resolves to: /usr/lib/jvm/java-1.18.0.1.1

JAVA_HOME should point to the JDK installation path and not to the java binary.
It should be something like "/usr/lib/jvm/default-java"  I think (not having an Ubuntu OS I don't havethe mean to verify that path).
Cheers,
Emmanuel

JAVA_HOME is set to the parent directory that java is installed to, so in your case JAVA_HOME=/usr
