Are you using Oracle Application Express in conjunction with the Oracle eBusiness Suite? If so, then we'd like to hear from you!
David Peake recently blogged about this, and is collecting information from the Oracle Application Express community. The purpose of this is to gather evidence with the eventual goal of formally legitimizing the use of Oracle Application Express with the Oracle eBusiness Suite.
If you are currently using Oracle Application Express with the Oracle eBusiness Suite (or other Oracle Applications, for that matter), I encourage you to read his blog and take his one page survey. You can provide as much or as little information as you wish, and you have my personal assurances - no sales or marketing representative will call.
