I think both Mod_plsql and Oracle Apex is free along with oracle 11g2. we have a custom application which is got created based on htp and htf packages. we would like to hear from you that if there are any tools / IDE to edit or enhance the existing application code (mod plsql based code to display table data in web UI format) ,or is it just manual coding practice like writing each tags individually?
Besides, can I use oracle Apex to edit the mod plsql based application. Will my current environment support if I upgrade oracle DB from 11g2 to 12c?
