Installing Java to Another Location on Centos 7

Question

I installed java before and i am running java applications on Centos, it is located at /usr/bin/java. For some other reason i want to install it to another location, let's say /myDirectory/java I downloaded java jdk as tar file and extract it to /myDirectory this directory then i set JAVA_HOME accordingly.

The problem is i can't start the applications anymore, the log says :

ERROR: JAVA_HOME is set to an invalid directory: /myDirectory/jdk1.8.0_181/bin/java

Please set the JAVA_HOME variable in your environment to match the location of your Java installation.

Is it because i had a prior installation? How do i achive this? Any help would be aprreciated, thanks.

Well, i am trying to change the JAVA_HOME, for a second and seperate installation of java. — İlker Demirci, Aug 15 '22 at 11:43

ERROR: JAVA_HOME is set to an invalid directory: /myDirectory/jdk1.8.0_181/bin/java

Your error suggests you set JAVA_HOME to the path of the java binary, but JAVA_HOME must point to the JDK directory, not the binary, i.e. JAVA_HOME=/myDirectory/jdk1.8.0_181, without /bin/java.

Hello, actually i already tried that one too, same error. – İlker Demirci Aug 16 '22 at 07:49
which tar did you download? can you include in your question what is inside your jdk directory (`ls /myDirectory/jdk1.8.0_181`)? – criztovyl Aug 16 '22 at 14:52
