Hi, I don't have root permission on my machine.
In this case, shall I use the source? http://www.java.net/download/jdk6/6u18/promoted/b02/jdk-6u18-ea-src-b02-jrl-09_sep_2009.jar How to install it? I got the following error. $ java jdk-6u18-ea-src-b02-jrl-09_sep_2009.jar Exception in thread "main" java.lang.NoClassDefFoundError: jdk-6u18-ea-src-b02-jrl-09_sep_2009.jar at gnu.java.lang.MainThread.run(MainThread.java:102) Caused by: java.lang.ClassNotFoundException: jdk-6u18-ea-src-b02-jrl-09_sep_2009.jar not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:./], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}} at java.net.URLClassLoader.findClass(URLClassLoader.java:529) at java.lang.ClassLoader.loadClass(ClassLoader.java:442) at java.lang.ClassLoader.loadClass(ClassLoader.java:377) at gnu.java.lang.MainThread.run(MainThread.java:98) Regards, Peng On Thu, Sep 17, 2009 at 6:06 PM, Peng Yu <[email protected]> wrote: > Hi, > > I'm not sure which one I should download on > http://java.sun.com/javase/downloads/index.jsp > > Java SE Development Kit (JDK) Bundles > > or > > Java SE Development Kit (JDK) > > What are Java EE, JavaFX SDK and NetBeans 6.7.1? > > Regards, > Peng > > On Thu, Sep 17, 2009 at 5:37 PM, Kelly O'Hair <[email protected]> wrote: >> You need a JDK to build the JDK. >> >> If you have a JDK (jdk6 vintage) on your system already, yes >> you can use that, just point ALT_BOOTDIR at it and skip step 1. >> >> -kto >> >> Peng Yu wrote: >>> >>> Hi, >>> >>> README of openjdk-7-ea-src-b71-03_sep_2009 says the following.
