前提條件：已經安裝成功了Openbravo ERP。未安裝成功的，請參考[url="http://liwenshui322.iteye.com/blog/1054473"]Openbravo ERP 3.0安裝指南[/url]

Openbravo現在完全可以在eclipse環境下開發，測試，部署，包括4個項目openbravo，core, trl 和wad，在相應目錄下都有eclipse的項目文件，項目可以直接導入到eclipse中。
環境需求
· Java Development Kit (JDK) 6.
· Apache Tomcat 6.x.
· Apache Ant 1.7.
· PostgreSQL 8.3.x.
開發工具
· Eclipse IDE for Java EE Developers.
[color=red]注意[/color]：取消自動編譯功能
導入openbravo到eclipse中，選擇File > Import... > Existing Projects into Workspace
選擇目錄D:\openbravo\OpenbravoERP-3.0RC6.1（即為安裝openbravo文件），接下來依次導入[b]OpenbravoCore[/b]，[b]OpenbravoTrl[/b]，[b]OpenbravoWAD[/b]，分別在目錄src-core, src-trl, src-wad.
設置所有項目的編碼為[b]UTF-8[/b], 以避免亂碼問題。
目前這些項目可能都有編譯錯誤，不用管它，繼續下面的操作。

BUILD SUCCESSFUL
Total time: 6 minutes 27 seconds
接下來依次進行如下操作：
需要修改class的輸出路徑：openbravo/WebContent/WEB-INF/classes，這樣才能在tomcat server中運行。
選擇項目 Openbravo然后點擊 Run > External Tools > eclipse.trl.lib
在 Console 窗口，確認有BUILD SUCCESSFUL 信息.
選擇項目 Openbravo然后點擊 Run > External Tools > eclipse.wad.lib
在 Console 窗口，確認有BUILD SUCCESSFUL 信息.
選擇項目 Openbravo然后點擊 Run > External Tools > eclipse.compile.complete
在 Console 窗口，確認有BUILD SUCCESSFUL 信息.
點擊 Project > Build Project 菜單進行編譯.
定義 Tomcat server
為了在eclipseIDE中運行OpenBravo，那么需要定義 Tomcat server.
點擊 window > Preferences > Server > Runtime Enviroments > Add > 選擇Apache tomcat 6.0 > 點next >選擇你安裝的tomcat目錄和jre > 選擇Openbravo項目 > 點擊finish。

雙擊打開添加的Tomcat Server > Server Locations一欄選擇“Use custom location”，Server path文本框輸入tomcat，Deploy path文本框輸入webapps > 選中Serve modules without publishing > 設置timeout下start（in seconds）為10000 > ctrl + s保存。
啟動Tomcat server(該操作會持續大幾分鐘，耐心等待。)
選中創建的server，然后點擊 start圖標，或者右鍵 start。
啟動完成后在瀏覽器中輸入：http://localhost:8080/openbravo
用戶名:Openbravo
密碼:openbravo

[size=large][color=red]需要注意的地方：[/color][/size]
1、eclipse報錯：java.lang.OutOfMemoryError: PermGen space
解決辦法：修改了安裝目錄eclipse.ini文件，在最后面增加了兩行
-XX:PermSize=128M
-XX:MaxPermSize=128M

2、eclipse下啟動tomcat報錯：java.lang.OutOfMemoryError: PermGen space
解決辦法：單擊run -> run configurations...，選擇配置的tomcat，在Arguments選項卡的 VM argument框最前面加上：-Xms256m -Xmx512m -XX:PermSize=128M -XX:MaxPermSize=1024m。如下圖：
