MarvinBeans error

Hi





I'd just installed MarvinBeans 5.0.6 on my HP workstation running RedHat EL4. However, I have a problem launching MarvinSketch. It gives me an unknown error:

Can anyone help?





Thanks in advance,

Which Java version do you use?


Marvin like any ChemAxon products accepts only Sun distributed Java versions (exclude the Macintosh platform where the Apple's built-in Java is accepted that is compatible with Sun's one).


Installation Guide for Marvin Beans

The command


& java -version





returned





java version "1.4.2"





In addition, I installed the JRE 1.6.06

Is it a Sun distributed Java?


Can you copy the whole output of the "java -version" statement? You should see something like that if it is a Sun Java.

Code:

java -version java version "1.4.2_12" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_12-b03) Java HotSpot(TM) Client VM (build 1.4.2_12-b03, mixed mode)

in effect, it's not a sun distributed version......





java version "1.4.2"


gcj (GCC) 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)

Dear Andrea,


Marvin does not support gcj. Please install a Sun distributed Java to be able to use Marvin.


Before you start installing Marvin, check that Sun's Java is the default one.


You can do it with the earlier mentioned java -version statement.
