Hi, On my ubuntu laptop I have a lot of Java installed.... see below the questions. I'd like to know - How I can manage these using update-alternatives because this seems to stay stuck on the open JDK java. - What exactly does java - version show me? (With respect to the below) - What's the best way to handle multiple java versions because even as things stand I have one application looking for Tomcat 6 which I think needs Openjdk 6 as a dependency. - Oracle vs. Open JDK - what's the point of having coke and pepsi? See my browser requirement below - And now the question which prompted this post..........I'm trying to (re)install lombok.jar by typing 'java -jar lombok.jar'. However it comes up with this message: 'To install lombok on Eclipse, re-run this jar file on a graphical computer system - this message is being shown because your terminal is not graphics capable'. Double-clicking the file in nautilus just opens a file unzip dialogue. Now last time I did something that made this work in bash........but unhelpfully I can't remember what. Any suggestions?
1. usr/lib/jvm (a) Two actual directories "java-7-openjdk-amd64" and "java-7-openjdk-common" (b) Four symlinks to the "java-7-openjdk-amd64" directory: "default-java", "java-1.6.0-openjdk", "java-1.7.0-openjdk-amd64", "java-6-openjdk" which look like they're there for legacy reasons i.e. catch any application looking for those folders and route to openjdk 7 This stuff was installed due to dependencies on other applications and would have come from a repository 2. usr/java Two actual directories "jdk1.7.0_11" and "jre1.7.0_11" I installed sun java jdk and jre here. the former for eclipse and the latter is the only way, in conjunction with Chrome browser v24 I can open an SSH browser session with Amazon EC2 which I think is quite convenient (Always crashes on me in bash...). Not being from a repository I assume these will not update. - opt/google/chrome/plugins points to /usr/java/jre1.7.0_11/lib/amd64/libnpjp2.so - JAVA_HOME points to /usr/java/jdk1.7.0_11 3. usr/bin/java This points to /etc/alternatives/java 4. /etc/alternatives/java This points to /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java -- -- You received this message because you are subscribed to the Linux Users Group.
