jboss与tomcat的使用经验总结

· 一:jboss简介

jboss是一套可以基于j2ee框架的全套解决方案,他包括JBoss/Server,JBoss/spyderMQ, JBoss/Jaws,JBoss/Zola,JBoss/Zoap,JBoss/Castor,JBoss/Tomcat。这些产品可以非常合理的搭建基于j2ee框架的软件产品和软件工程。 虽然他的诞生才一年多，但是就像apache一样，他是完全公开源代码的，他是真正具有生命力的产品的他将像其他免费软件一样成为成功的Application server。 

本文主要是介绍如何安装该软件产品，如何配置他与Tomcat的结合，如何通过Tomcat的Servlet调用Ejb。最终完成Apache+Tomcat+jboss的Web综合解决方案。我本人也是在上个星期天才刚刚认识他的，短短的5天我也只是大概的了解了他的功能和特点。对他的大部分功能不是十分清楚，如果我有时间我会把有关jboss的其他内容逐步介绍给大家，但不是现在。 

好了现在开始我们的Apache+Tomcat+Jboss的旅程吧。 


（ 一）系统环境简介： 


硬件平台： 

PC 233 32M RAM 6GHand Disk 

操作系统： 

red head liunx 6.1 （由于jdk1.3的要求，必须使用6.1以上的版本，或者将glibc更新到2.1.2.11版本或更高。） 


应用环境要求： 

jdk1.3 
jaxp1.0.1 
Apache 3.1.2 
Tomcat 3.2 beta 4 （jakarta-ant，jakarta-servletapi，jakarta-tomcat） 
jBoss 2.0 BETA-PROD-PRE-05 
interestEJB.tar.gz 测试EJB的源代码。 

安装过程叙述如下： 
假设当前目录是：/home/liling 
准备工作如下： 
mkdir tomcat 
mkdir jboss 
cp j2sdk-1_3_0-linux-rpm.sh /home/liling/. 
cp jakarta-ant.tar /home/liling/tomcat/. 
cp jakarta-servletapi.tar /home/liling/tomcat/. 
cp jakarta-tomcat.ta /home/liling/tomcat/. 
cp jboss-cvs-sources.zip /home/liling/jboss 
cp interestEJB.tar.gz /home/liling/jboss 


一：安装jdk1.3 
sh j2sdk-1_3_0-linux-rpm.sh 
rpm -iv j2sdk-1_3_0-linux-rpm 

将看到/usr/java/jdk1.3目录 
JAVA_HOME = /usr/java/jdk1.3 
PATH = $PATH:/usr/java/jdk1.3/bin 
export JAVA_HOME 
export PATH 
jar -xvf jaxp-1_0_1.zip 


将看到在当前目录生成jaxp1.0.1目录 

CLASSPATH=$CLASSPAHT:/home/liling/jaxp-1.0.1/jaxp.jar:/home/liling/jaxp-1.0.1/parser.jar 
export CLASSPATH 

一：安装Tomcat。 

Tomcat的安装过程包括安装ant和servletapi的过程 
首先将Tomcat的jakarta-tomcat.tar.gz解包。然后读取README的过程安装。 
cd /home/liling/tomcat 
gz -d jakarta-tomcat.tar.gz 
tar -xvf jakarta-tomcat.tar 
cd jakarta-tomcat 
vi README 

将看到如下安装过程 
cd $JAKARTA_HOME/jakarta-ant 
./bootstrap.sh <-- Unix 
This should result in the creation of a file "ant.jar" in the "lib" 
subdirectory, which will be used when building Watchdog. 
cd $JAKARTA_HOME/jakarta-servletapi 
./build.sh dist <-- Unix 
This should result in the creation of a file "servlet.jar" in the "lib" 
subdirectory, which will be used when building Watchdog. 
cd $JAKARTA_HOME/jakarta-tomcat 
./build.sh <-- Unix 


按照上面的过程完成安装将会出现下面的目录： 
./build 
./build/ant 
./build/serletapi 
./build/tomcat 
./dist 
./dist/servletapi/lib 
在./build/tomcat/bin/startup.sh和./build/tomcat/bin/shutdown.sh 用于启动和停止tomcat。 


· 二：安装jboss。 

配置TOMCAT_HOME环境变量: 
TOMCAT_HOME=/home/liling/tomcat/build/tomcat 
export TOMCAT_HOME 
cd /home/liling/jboss 
jar -xvf jboss-cvs-sources.zip 
cd src 
cd build 
./build.sh 

· 三：启动jboss: 
cd /home/liling/jboss/dist/bin/ 
/run.sh 


· 四：配置Tomcat与Jboss 

cd /home/liling/jboss/dist/conf 

vi jboss.conf 

会看到如下提示： 

<!-- -- Uncomment this to add "Integrated Stack (fast) Tomcat support". 
-- This service allows you to integrate the stack of Tomcat and jboss. 
-- Invocations are not going through network but pass native pointers resulting in dramatic speed increases. 

-- This service allows the J2EE deployer to add and remove Tomcat contexts dynamically 

-- through JMX for you and in effect deploy EARs. Note that tomcat´s server.xml file will not be processed: 

-- you can only use JMX to add contexts. Use the J2EE deployer to deploy full EARs on this stack 

-- Be sure to set your ´TOMCAT_HOME´ environment variable before starting JBoss. 

-- 

-- The ARG tag is the port to run tomcat on. 

-- 

-- MLET CODE = "org.jboss.tomcat.EmbeddedTomcatService" ARCHIVE="jboss.jar" CODEBASE="../../lib/ext/"> 

-- ARG TYPE="int" VALUE=8080> 

-- /MLET> 

--> 

在上面的提示下添加下面的内容 


< MLET CODE = "org.jboss.tomcat.EmbeddedTomcatService" ARCHIVE="jboss.jar" CODEBASE="../../lib/ext/" > 

< ARG TYPE="int" VALUE=8088 > 

< /MLET > 

还会看到下面的提示： 

< !-- 

-- Uncomment this to add "Stand-alone Stack Tomcat support". 

-- This means that JSP and Servlets will work with EJB in different stacks and 

-- communicate through network invocation. If you benchmark j2ee please use "integrated stack". 

-- Also note that you cannot use the J2EE deployer with Tomcat in this configuration. 

-- Be sure to set your ´TOMCAT_HOME´ environment variable before starting JBoss. 

-- Note: this reads the server.xml configuration file of Tomcat, you can´t use the j2ee deployer 

-- 

-- MLET CODE = "org.jboss.tomcat.TomcatService" 

ARCHIVE="jboss.jar" CODEBASE="../../lib/ext/" > 

-- /MLET > 

-- > 

在上面的提示下添加如下内容： 

< MLET CODE = "org.jboss.tomcat.EmbeddedTomcatService" ARCHIVE="jboss.jar" CODEBASE="../../lib/ext/" > 

< ARG TYPE="int" VALUE=8088 > 

< /MLET > 

现在在启动jboss可以看到如下提示： 

[EmbeddedTomcat] Starting 

[EmbeddedTomcat] Testing if Tomcat is present.... 

[EmbeddedTomcat] OK 

[EmbeddedTomcat] ContextManager: Adding context Ctx( ) 

[EmbeddedTomcat] path="" :jsp: init

这表示Integrated Stack (fast) Tomcat support已经启动成功。
