JChemManager

Hi,





Just installed JChem (from jchem3[1].1.7.zip. All is fine. Now I want to create a table in Oracle to store structures.


I have a couple of questions. JChem Docs say that searching is quicker on JChem tables.





1. Is it possible to create these by hand (i.e. not using JChemManager)?


2. I cannot get JChemManager to run - the error message I get is





Exception in thread "main" java.lang.NoClassDefFoundError: chemaxon/jchem/JChemManager.





I have followed the setup as per the docs. I have no JChemManager dir on that path. Is it included with the zip I downloaded?





Machine specs are as follows:


Windows 2003 Server with SP1


Intel 3GHz P4 with 1GB RAM


Java version - 1.5.0_07


JChem version 3.1.7





Cheers

At table creation JChem also creates other database objects and writes some data into the property table.


So though it's possible, it's far from being straightforward, so I don't recommend it unless it's absolutely unavoidable.

This is the relevant page on setting up environmental variables:


http://www.chemaxon.com/jchem/doc/admin/prepscripts.html





The JChem directory is included in the package.


For example if you extract it under the root of the C: drive it will be:


C:\jchem





For sake of simplicity, please do not put JChem under directories containing spaces.





Also make sure that you have the JCHEMHOME environment variable set correctly (pointing to the jchem directory).


You can check it by typing


set JCHEMHOME





Let me know if this helps.

Yes,





I had the JCHEMHOME pointing at \jchem\bin, not \jchem
