Internet Sales 3.1 webshop & Netweaver Developer studio

Hi,

Does anyone know if it is possible to use the Netweaver Developer Studio IDE to make custom modifications on the webshop that is deployed on the SAP J2EE engine?

So far I have been using other tools to edit JSP's and create Java classes and have been compiling from the command line. I have not been succesful in setting up the Sneak Preview edition for this purpose, but would really like to use it.

All suggestions/remarks are very welcome !

Regards,

Manuel.
