I downloaded and installed sun's jdk1.5.0_06 to my FC3 box in /usr/share/jdk1.5.0_06/. I fiddled around with the symlinks to point to the binaries in .../bin/ and javac etc. now run. However, I get a java.lang.ClassCastException: SwingUI at sun.applet.AppletPanel.createApplet(AppletPanel.java:721) at sun.applet.AppletPanel.runLoader(AppletPanel.java:650) at sun.applet.AppletPanel.run(AppletPanel.java:324) at java.lang.Thread.run(Thread.java:595) when I try to view the class built from the simple code at the end of this message with appletviewer (all of the code there for completeness). I do think java doesn't find javax.* - and don't know how to tell it where it is. I've set my JAVA_HOME=/usr/share/jdk1.5.0_06/ (that's where my installation is). Any idea what is going wrong here? (I posted a similar question to the parallel sun-list, but got no solution from there...)
