[Orchem-devel] OrChem: Webapp example : problem by applet loading

[Antoine L. <al...@in...>]

Hi,

I have some questions.

Question  1) 
After having checkout the Orchem projekt from svn, create the property
file [1] , I could build without problem the war file. Than I try to
deploy it in Tomacat and in JBoss. This worked also fine. I can search
SMILES. The only problem is with the loading of the applet. Something is
wrong with the class loader. It say always :

charger : classe
org.openscience.jchempaint.applet.JChemPaintEditorApplet introuvable.
java.lang.ClassNotFoundException:
org.openscience.jchempaint.applet.JChemPaintEditorApplet
    at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source)
    at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source)
    at
sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown
Source)
    at java.lang.Thread.run(Unknown Source)
Exception : java.lang.ClassNotFoundException:
org.openscience.jchempaint.applet.JChemPaintEditorApplet

I try it in Firefoxe and Explorer. the same apend. Something get wrong
with the <applet> tag and the classloader. I have so 0 experience with
jsp. I have check: the jar containing JChemPaintEditorApplet
jchempaint-applet-core.jar is there.  Any idea what's goes wrong ?
By my version the JSP snippet looks like:

<applet code="org.openscience.jchempaint.applet.JChemPaintEditorApplet" 
	archive="jchempaint/jchempaint-applet-core.jar" 
	id="editor"
	name="editor" 
	width="700" 
	height="500">
<param name="impliciths" value="true"></param>
<param name="codebase_lookup" value="false"/>
<param name="onLoadTarget" value="statusFrame"></param>
<param name="image" value="hourglass.gif"></param>
<param name="boxborder" value="false"></param>
<param name="centerimage" value="true"></param>
</applet>

Question  2) 
An other basic oracle question: when I tell orchem (in the parameter
table) that it has to take a specific table can I do this to a table
that is in an other shema ? Do I have the right to do this ? Or do I
have to setup this right specifically in oracle ? How it looks like in
the parameter table ? simply schemaname. tablename ? 


Question  3) 
How can I calculate the molecular mass and the empirical formula (like
C6O6H12) of a molecule using the cartridge ?



Thanks for your help

[1] by the way in the properties/README you say that we have to create
the directory "my_local_properties". Is it not "my_local_copies" ? I
would also add that it has to be created in the "properties" directory.
