10个经典的 Java main 方法面试题

关于Eclipse、Lomboz、JBoss的客套话免了，直接进入正题。
一、下载、安装和配置

1. 所需软件

WindowsXP SP1
JDK 1.4.2-04 可以从SUN官方网站下载
MySQL4.1.8
Eclipse 3.0.1及 语言包
Lomboz3.0.1

JBoss 4.0.0
JBoss-IDE 1.4.0
XDoclet 1.2.2

2. 下载

●Eclipse 3.0.1及 语言包
参考：http://blog.csdn.net/javamxj/archive/2004/10/11/131952.aspx

● Lomboz3.0.1

lomboz.301.zip(这是7月22日发布的版本)
http://download.forge.objectweb.org/lomboz/lomboz.301.zip

http://download.fr2.forge.objectweb.org/lomboz/lomboz.301.zip

http://download.us.forge.objectweb.org/lomboz/lomboz.301.zip

emf-sdo-runtime-2.0.0.zip
http://download.forge.objectweb.org/lomboz/emf-sdo-runtime-2.0.0.zip

http://download.fr2.forge.objectweb.org/lomboz/emf-sdo-runtime-2.0.0.zip

http://download.us.forge.objectweb.org/lomboz/emf-sdo-runtime-2.0.0.zip

现在主页上有1月6日的新版本，包括3.1和3.0.1的版本，使用后发现有一些小bug，所以还是推荐使用7月22日发布的版本。

● JBoss 4.0.0

http://prdownloads.sourceforge.net/jboss/jboss-4.0.0.zip?download

这是一个zip版本，从上面的站点选择一个镜像下载。

● JBoss-IDE 1.4.0http://www.jboss.org/products/jbosside

现在改名了 JBoss Eclipse IDE，几天不见就换马甲了。

开发JBoss时使用的Eclipse插件，这里我主要使用它的Xdoclet的提示功能，另外它整合了SolarEclipse。

http://prdownloads.sourceforge.net/jboss/org.jboss.ide.eclipse_1.4.0.bin.dist.zip?download

●MySQL4.1.8
参考：http://blog.csdn.net/javamxj/archive/2005/01/13/251861.aspx

● XDoclet 1.2.2

这里主要是为了替换Lomboz中的XDoclet 1.2.1版本。
参考：http://blog.csdn.net/javamxj/archive/2005/01/11/248337.aspx

3. 安装

F:\j2sdk JDK目录
F:\java\xdoclet XDoclet目录
F:\java\jbossJBoss 目录
D:\eclipse Eclipse 3.0.1 目录
D:\eclipse\myplugins\lomboz.301 Lomboz 目录
D:\eclipse\myplugins\jboss-ide-1.40JBoss-IDE 目录
D:\mysqlMySQL4.1.8 目录

· lomboz和jboss-ide 我都是采用links方式安装的， 参考 http://blog.csdn.net/javamxj/archive/2004/10/11/132311.aspx

二. 配置开发环境

打开Eclipse，如果界面是“资源透视图”，那么切换到“Java透视图”。点击菜单“窗口”->首选项，以下都在“首选项”中配置：
1. Java->构建路径


2. Lomboz



3. Lomboz ->Server Definitions ->Properties

因为使用的JBoss 4.0.0服务器不在 Lomboz 默认服务器之列，所以需要自己建立一个jboss400.server 文件。
先把下面的jboss400.server 文件复制到Lomboz目录下的 com.objectlearn.jdt.j2ee_3.0.1\servers 目录（如果你是把Lomboz直接安装在Eclipse的Plugins目录中，这个子目录就是“Eclipse安装目录\plugins\com.objectlearn.jdt.j2ee_3.0.1\servers”；如果你是采用links方式安装lomboz的，那么这个子目录就是“Lomboz安装目录\eclipse\plugins\com.objectlearn.jdt.j2ee_3.0.1\servers”）。这个目录下有许多server类型文件，可以把其中认为不需要的文件删除。

然后切换到Eclipse，效果如下图


4. 切换到主界面，点击“窗口”菜单->定制透视图



最后，确定即可。
