Java upgrade problem on CentOS 6.5
Clash Royale CLAN TAG#URR8PPP
I want to upgrade my jdk
on a CentOS
server, after some simple searches I found some solutions.
From this link, you can see that the instructions are simple.
install your chosen jdk from rpm package or from source
possibly choose some alternatives
check that the new version installed (
java -version
)
The first two steps above, I easily completed, but in check version step I get this error:
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
I have also checked:
alternatives --config java
and symbolic links.
I have also tried which
command to find out what java is actually running and this was the link directions.
/usr/bin/java -> /etc/alternatives/java -> /usr/java/jdk-1.8.0_40/bin/java
the weird thing is that when I run:
/usr/bin/java -version
It is OK and it returns the version but when I run java
without any prefix I got that error.

The problem was a system variable CLASSPATH
.
and it must be exported in some way for example /etc/bashrc
file because jdk needs to know the pass of classes and libraries to load it's modules.
in my case i sat CLASSPATH=/usr/java/jdk1.8.0_40/lib
.
