ChemAxon products support only Sun distributed Java. On Mac platform (where Sun Java is not available), our products support Apple's built-in Java that is compatible with Sun's distribution. Marvin applets requires at least Java 1.5.
Several packages can be downloaded from the Marvin site:
Download and unpack:
zip: unzip marvin-bin-5.0.0alpha12.zip tar.gz: gunzip < marvin-bin-5.0.0alpha12.tar.gz |tar xf -This distribution contains all files necessary for using MarvinSketch and MarvinView applets, without HTML pages and examples.
Download and unpack:
zip: unzip marvin-all-5.0.0alpha12.zip tar.gz: gunzip < marvin-all-5.0.0alpha12.tar.gz | tar xf -This distribution contains all files necessary for using MarvinSketch and MarvinView applets, as well as the documentation and examples.
The following jar files should not be modified because they are signed jars. If you do so, the modified jar is no longer signed.
marvintmp
unzip -o jmarvin.jar -d marvintmp unzip -o sjars/abbrevgroupexport.jar -d marvintmp unzip -o sjars/batik-core.jar -d marvintmp unzip -o sjars/clean2d.jar -d marvintmp ...
cd marvintmp zip jmarvin.jar *
sjars/batik-core.jar
can be skipped.
Remove
chemaxon/marvin/plugin
and sjars/plugin
directories
from the marvin
directory.
cd marvin rm -r chemaxon/marvin/plugin rm -r sjars/plugin
Unzip the signed jar file into an empty directory. Delete signing information from the
META-INF
directory. Finally, create
a new jar file with the content of the directory.jmarvin.jar
file under Linux:
unzip -d targetdir jmarvin.jar cd targetdir rm -f META-INF/CHEMCERT.* zip jmarvin.jar *Under Linux and Unix, you can run
unsigner.sh
to unsign signed
jar files in Marvin:
cd marvin ./unsigner -a
The rotation and the linkage to the sketcher have negligible contribution to the memory footprint. The largest contributions are from
Even if we provided a "thin" applet without 3D support, it would only enable you to use about twice as many molecules. Then you would run out of memory again because of the double buffering.
You should use an n-molecule scrollable MView table instead of n applets. Then the common data will be stored in only one place (instead of n) and the number of Swing components will be equal to the number of visible molecules which is usually much smaller than n.
Your molecule string may contain consecutive space characters in applet parameters which are converted to only one space. This bug applies to Mozilla 0.9.7-1.0 and probably some earlier versions too.
These browsers do not include any Java. They require Java Runtime Environment (JRE) 1.4.2 or later.

Netscape 6 and Netscape 7.0 contain a built-in Java to run applets. If your browser does not include any Java or you would like set a new default, do the following. (These browsers accept both 1.3.x and java 1.4.x.)
ln -s <JRE_HOME>/plugin/i386/ns600/libjavaplugin_oji.so libjavaplugin_oji.soWhere
<JRE_HOME>
is the home
directory of the required Java Runtime Environment.
In a few cases, the browser can not recognize Java plug-in although you have created the
libjavaplugin_oji.so
symbolic link in the plugin
directory.
In that case, add a new symbolic link (libjavaplugin_oji140.so
) to the
plugin
directory.
Then restart the browser.
ln -s <JRE_HOME>/plugin/i386/ns600/libjavaplugin_oji.so libjavaplugin_oji140.so
