Therefore, any other Java implementation is not supported. Due to this we only develop and test our software suite against Oracle's JDK and JRE, allowing us to guarantee the behaviour of both our software, and the environment it is installed in. The CaféX Fusion Application Server has class dependencies that are only satisfied by the Oracle Java stack. CafeX recommends using the /usr/java/latest softlink which will make updating the java version seamless. Note that when installing CafeX software the path to the installed version must be specified. 1 root root 16 Jun 17 18:48 default -> /usr/java/latestĭrwxr-xr-x. Note that java will be installed into /usr/java and establish softlinks as follows: Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode) Java(TM) SE Runtime Environment (build 1.8.0_151-b19) This will install the update 131 of java 8: This will download the rpm into the current folder. # wget -no-check-certificate -no-cookies -header "Cookie: oraclelicense=accept-securebackup-cookie" ![]() The rpm can also be downloaded using wget as follows: Note that this article will install using the rpm. Note that the 64bit linux version is required - jdk-8u131-linux-圆4.*. Note that at on the publish date of this article CaféX software has been verified with Java 8 which can be obtained from the Oracle website. bash: /usr/bin/java: No such file or directory The java -version command should no longer display the currently installed java version. Note that the output has been omitted for brevity The following command will remove all java packages. OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode) The output from java -version will display the currently installed java version. The step by step commands are listed after a short video. A google search for "how to remove OpenJDK and install Oracle JDK" will yield many other sources of excellent information. Note that the procedure has been verified in RHEL 6.4 64bit minimal server. ![]() This article outlines a procedure that can be used to uninstall OpenJDK and install Oracle JDK in preparation of a host for installing CafeX software. ![]()
