在RPI上安装JDK8的路径不起作用

Question

I have tried to upgrade my existing JDK8 on my Raspberry Pi, but I failed.

I downloaded the ARM version from the oracle site, extracted it in Windows, transferred it to my pi via FTP and copied it to /usr/local.

Then I tried to link the folder to $PATH or update-alternatives, but the terminal and tomcat will not recognize I have java installed.

I know you have to edit bash.bashrc, environment or profile to edit the PATH for every boot, but this does not even work in the same session.

Update:

I solved my problem on my own now somehow...

I reinstalled the OS completely and followed some tutorial to update jdk, again. Downloaded, unzipped, chmod, set PATH and JAVA_HOME, set update-alternatives and this time it worked somehow...

Answer 1

cd /usr/local/jdk8/bin
sudo chmod +x java
