一、前言 <br>
<br>
Jboss为Open Source，完全免费的Appliaction Server，对于J2EE有很好的支持，可以和Tomcat完美结合。 <br>
<br>
二、下载，安装<br>
<br>
下载地址为Jboss官方站点：http://www.jboss.org/，我下载的是Jboss2，而且和tomcat一起的，这样避免了单个下载一起配置的问题。下载地址是：http://www.jboss.org/jboss_tomcat.zip<br>
<br>
下载完，解压到一个目录，我这里用E:\jboss_tomcat作为例子。下面有子目录:<br>
<br>
E:\jboss_tomcat\jboss2<br>
<br>
和<br>
<br>
E:\jboss_tomcat\tomcat32b7<br>
<br>
注意，我这里的目录稍微做了改动的，这样如果你不将TOMCAT_HOME加到CLASSPATH中，E:\jboss_tomcat\jboss2\bin\run_with_tomcat.bat这个文件要做相应改动才能正常运行。<br>
<br>
<br>
<br>
三、配置运行<br>
<br>
基本上不要什么配置的，只要安装好了JDK，当然，最好将TOMCAT_HOME加到CLASSPATH中。<br>
<br>
这样，E:\jboss_tomcat\jboss2\bin\run_with_tomcat.bat这个文件前的TOMCAT_HOME就可以去掉了。<br>
<br>
运行E:\jboss_tomcat\jboss2\bin\run_with_tomcat.bat这个文件，这样，Tomcat端口在8080，Jboss为8083，<br>
<br>
运行http://localhost:8080/将出现tomcat首页，<br>
<br>
运行http://localhost:8083/将出现无错误的空白页，<br>
<br>
<br>
<br>
四、测试EJB<br>
<br>
(1)启动JBOSS：<br>
<br>
方法见上：<br>
<br>
<br>
<br>
<br>
<br>
(2)下载代码：<br>
<br>
http://www.wodejia.net/softdownload/java/interestejb.zip<br>
<br>
解开，出现如下目录：<br>
<br>
interest/com<br>
<br>
interest/docs<br>
<br>
...<br>
<br>
全部copy到jboss2下examples目录下，如果没有examples目录，建立一个，结构如下：<br>
<br>
E:\jboss_tomcat\jboss2\examples\interest\...<br>
<br>
将文件E:\jboss_tomcat\jboss2\examples\interest\interest.jar复制到：<br>
<br>
E:\jboss_tomcat\jboss2\deploy下：<br>
<br>
在CLASSPATH中加入如下文件：<br>
<br>
E:\jboss_tomcat\tomcat32b7\lib\servlet.jar;E:\jboss\client\jboss-client.jar;E:\jboss\client\jnp-client.jar;E:\jboss\lib\ext\ejb.jar;E:\jboss\examples\interest\interest-client.jar <br>
<br>
为了测试Client通过servlet调用EJB，必须将： E:\jboss_tomcat\jboss2\examples\interest\下EJB.class和EJB.java复制到：<br>
<br>
E:\jboss_tomcat\tomcat32b7\webapps\ROOT\WEB-INF\classes目录下<br>
<br>
重新启动JBOSS_TOMCAT<br>
<br>
<br>
<br>
<br>
(3)command下client测试运行：<br>
<br>
command下，进入目录E:\jboss_tomcat\jboss2\examples\interest<br>
java InterestClient<br>
<br>
将出现：<br>
<br>
Got context<br>
<br>
Got reference <br>
<br>
Interest on 1000 units, at 10% per period, compounded over 2 periods is: 210.00000000000023 <br>
<br>
jboss窗口将出现：<br>
<br>
[Interest] Someone called `calculateCompoundInterest!' <br>
<br>
(4)web下client通过Servlet测试运行：<br>
<br>
http://cgreen:8080/servlet/EJB<br>
<br>
将出现：<br>
<br>
Interest on 1000 units, at 10% per period, compounded over 2 periods is: 210.00000000000023 <br>
<br>
jboss窗口将出现： <br>
<br>
[Interest] Someone called `calculateCompoundInterest!' <br>
<br>
到此已经成功了。 <br>
