我关注的开源ERP,CRM

1,hipergate
 又是西班牙出的，为什么西班牙和葡萄牙两牙都喜欢ERP开源呢？
口气很大,看他说的:什么使hipergate如此独一无二?

It is completely free.

It is the only Open Source application with such a wide functional coverage.

Runs on multiple databases and operating systems

Has a unitary conceptual design and implementation.

Is adequate for being used by Application Service Providers.

Supports multiple languages.

Has a professional services support network.

Is well documented.

hipergate所有的实体类都继承自com.knowgate.dataobjs.DBPersist，好像增删改查的代码都不用自己写了，值得研究。

2,vtiger 就更狂妄了，竟然声称是"The best OpenSource CRM on the planet"!
   看过其demo，做得还真不赖，模块比较齐全，界面上很多细节处理得很精致，比较人性化，可惜不是java做的。为什么很多java做的web系统听起来牛鼻子哄哄的，使用起来却惨不忍睹？真想把vtiger的老虎皮剥下来用在我的java上。

3,oaj ,貌似不错，可惜已经两年多没更新了。
    OAJ (OpenAccountingJ) is a free, open-source, web-based Accounting/ERP system. Built in Java using the best-of-breed Open Source components, such as Spring Framework, Acegi Security, Hibernate, Jasper Reports, XDoclet it offers a solid, customizable, secure platform for your business.

4,Openbravo 和Compiere这两个就不说了。
