Are you also going to install an SAP R/3 system with ABAP enviroment, MaxDB, application server and the R/3 frontend too? NetWeaver shines best together with SAP's own ERP system. According to my instructor, 5G will do for a personal edition. There's only 4.3G free in my laptop, so I gave up.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
