Question : We want to write a ERP-Software for our company.The number of users will be up to 200 (mostly not at the same time). Since usability is important, we plan to choose a Swing GUI. What do you think of it? Do we need J2EE for that? Or is this a bit too much? If you need more information to answer that question, please ask me.
Answer : Of course you do not need J2EE. If your company has an email system and Microsoft Office, you could email spreadsheets back and forth.
I like Java. Full response to question is here
