Richtext to HTML (and back to Richtext)

Hello

In our ERP client/server application, written with powerbuilder (actually 11.5), we are using several fields in RichText mode.

An external CRM program needs to read (SELECT), edit (HTML) and store (RICHTEXT) back to the database.

Any ideas for the best practices to do that ?

We try to implement 2 Java functions into the database (SQL Anywhere 12) to convert the data "on the fly" in SELECT and UPDATE but the conversion results are too bad.

Thank you
