I am trying to start morpho.

I have set my Paths as such:

desktop:~$ echo $JAVA_HOME /usr/lib/jvm/java-6-sun

desktop:~$ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/java-6-sun/bin

but when I try to launch morpho using

./morpho-1.9.0/morpho

I get the following error

ls: cannot access ./lib/*.jar: No such file or directory Using dynamic classpath: .:/usr/lib/jvm/java-6-sun/jre/lib/rt.jar

java version "1.6.0_24" Java(TM) SE Runtime Environment (build 1.6.0_24-b07) Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode)

Exception in thread "main" java.lang.NoClassDefFoundError: edu/ucsb/nceas/morpho/Morpho Caused by: java.lang.ClassNotFoundException: edu.ucsb.nceas.morpho.Morpho at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) Could not find the main class: edu.ucsb.nceas.morpho.Morpho. Program will exit.

Not sure why this is happening, but I do have both java-6-sun and java-6-openjdk installed, and I get a similar error when setting either as the JAVA_HOME path.

Moot point now:

Hi David, Try changing into the morpho-1.9.0 directory and invoking the script from there: cd morpho-1.9.0 ./morpho

I believe the script assumes relative paths from that directory.

I totally agree with Ben. The script should be run under morpho-1.9.0.

For what it's worth, on my linux box I keep a simple bash script named 'morpho' in ~/bin (which is on my path). I just start morpho at the command line that way, from anywhere. You'd need to tweak the paths to match your morpho install, of course:

----------------------------------------------------

!/bin/bash

export JAVA_HOME='/usr/lib/jvm/java-6-sun/jre' cd /opt/morpho-1.9.0 ./morpho

----------------------------------------------------

Just remember to update it the next time you install a new morpho version and/or upgrade java!
