JChemSearch , ConnectionHandler object , Driver

Hello

I`m run groovy scripts from Instant JChem.
I use MySQL database.

I tried to do an overlap analysis through JChemSearch class object. It needs a ConnectionHandler.
I am connected to database and get parameters from schema.databasePlatform.dataSource.

I create new Connection object, but It cannot find Driver for my database.

Is JChemSearch needs a new ConnetionHandler? Is there posibility to access to current ConnetionHandler?

Please help

Dear Rafal,

would not it be easier to do the overlap analysis with integrated tools in IJC? (documentation)

Regarding the database connection. Did you refer to the documentation here? I would suggest this approach from Instant JChem, instead of relying on getConnection() and getConnectionHandler() from JChemSearch object and 

Wishing all the best

Thank you for reply

I would like to use script, because in opinion of others it is more "comfortable" (clicking two or three times and an output file is created)

I tried this approach:
https://docs.chemaxon.com/display/jchembase/Structure+Searching#StructureSearching-duplicate />Here is my Nemesis: 
    searcher.setConnectionHandler(connHandler);

I tried: Connection con = this.dataSource.getConnection() (class as in post above)
But ConnectionHandler (https://www.chemaxon.com/jchem/doc/dev/java/api/chemaxon/util/ConnectionHandler.html)
throws an exception:
groovy.lang.GroovyRuntimeException: Could not find matching constructor for: chemaxon.util.ConnectionHandler(com.im.commons.db.datasource.BaseDataSource$ConnectionWrapper)

(ConnectionWrapper inherited from Connetion object)

Best regards
