List of open source softwares for Production

Hi,

Me and some friends are planning to create an application for school/colleges (used by maximum 2000 users).

Since we have planned to charge nill/moderate amount to implement this app we need to use open source softwares.

Here is list of applications we are planning to use
1. IDE + Server: (NetBeans + Glassfish) OR (Eclipse + JBoss)
2. DB: MySQL Community Server
3. Project Management: ???
4. Version Control: ???
5. Build: Maven/???

Technologies decided
1. Portal JSR 168
2. AJAX
3. JSF/???
4. Spring/EJB 3.0
5. Hibernate

Could you please let me know which softwares/technologies would be appropriate for Production use considering reliability, scalability, uptime etc and also from maintenance point of view.
Also i am not sure which free Project Management application is opensource and the best.

Moderator, If necessary could you please move this thread to appropriate forum.

Thanks a lot

This sort of question is normally dealt with in the Intermediate forum, but since you're asking about open source tools it can happily stay here.

To quickly add my advice:

Project Management: Trac+ or Jira
Source control: SVN (as it integrates with Trac+ and Jira and most IDEs)
Build: Maven or Ant

Hope that helps a little!

Though you may get viable options for all others, there has to be clear separation and may be a tug of war between Spring/EJB/Hibernate. Try doing a detailed analysis and full requirements and take a call on this.

For project management I would recommend to have a look at Redmine (http://www.redmine.org/).

Thanks for the help. I have planned to go with Trac and SVN.
