Help needed for newbie EJB

Question

Hi, all
I am a newbie in EJB and I am following the example in the URL:
http://www.huihoo.com/jboss/online_manual/3.0/
I am working on the 'interest' example in the first chapter.
When it come to 'Packaging and deploying the bean', I got some meaage like this:
ant intro-interest-jar
Buildfile: build.xml
validate-servlet:
validate-jboss:
fail_if_not_valid:
init:
[echo] Using JBoss directory=/opt/jboss
[echo] Using base classpath=/opt/jboss/client/jboss-j2ee.jar:/opt/jboss/client/jaas.jar:/opt/jboss/client/jbosssx-client.jar:/opt/jboss/client/jboss-client.jar:/opt/jboss/client/jnp-client.jar:/home/xiaobo/learningejb/examples/COULD_NOT_FIND_SERVLET_JAR
[echo] Using Source directory=/home/xiaobo/learningejb/examples
[echo] Using Build directory=/home/xiaobo/learningejb/examples/build-examples
intro-interest-jar:
compile:
ejb-jar:
[delete] Deleting directory /home/xiaobo/learningejb/examples/build-examples/interest/META-INF
[mkdir] Created dir: /home/xiaobo/learningejb/examples/build-examples/interest/META-INF
[copy] Copying 1 file to /home/xiaobo/learningejb/examples/build-examples/interest/META-INF
[copy] Copying 1 file to /home/xiaobo/learningejb/examples/build-examples/interest/META-INF
[jar] Building jar: /home/xiaobo/learningejb/examples/build-examples/interest/interest.jar
BUILD SUCCESSFUL
Total time: 2 seconds
Why did I get this:
/home/xiaobo/learningejb/examples/COULD_NOT_FIND_SERVLET_JAR.
But if I check the "interest.jar" by using 'jar -tvf interest.jar' in the "~/learningejb/examples/build-examples/interest$" directory, it seems it had all files and directories in it.
But if I copy this jar file into the deploy directory in jboss, and I check the log file 'server.log'
I found this error message:
2005-11-28 17:31:03,536 DEBUG [org.jboss.management.j2ee.LocalJBossServerDomain] handleNotification: javax.management.Notification[source=jboss.ejb:service=EJBDeployer,type=org.jboss.deployment.SubDeployer.stop,sequenceNumber=15,timeStamp=1133213463536,message=null,userData=org.jboss.deployment.DeploymentInfo@c36a9f52 { url=file:/opt/jboss-3.2.5/server/default/deploy/interest.jar }
deployer: org.jboss.ejb.EJBDeployer@3c9c31

lastDeployed: 1133210324921
lastModified: 1133210324000
mbeans:
Then I add the follwoing line into the 'ejb-jar.xml':
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">
so the 'ejb-jar.xml' looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">
<ejb-jar>
<description>JBoss Interest Sample Application</description>
<display-name>Interest EJB</display-name>
<enterprise-beans>
<session>
<ejb-name>Interest</ejb-name>
<home>org.jboss.docs.interest.InterestHome</home>
<remote>org.jboss.docs.interest.Interest</remote>
<ejb-class>org.jboss.docs.interest.InterestBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>
</session>
</enterprise-beans>
</ejb-jar>
and I rejar it and copy the jar file into the deploy directory. I still got the same error message in the log file???!!!
Please help!

It's a no brainer between the AirPort Extreme and Airport Express.
The AirPort Extreme has 6 wireless antennas up at the top of the "tower", while the AirPort Express has four, so the Extreme has significantly better wireless speed and range than the Express.
As you know, the broadcast power of wireless routers is limited by law, and most routers are running full blast. Apple routers are not known for their broadcast power, so what we cannot tell you is whether the Extreme will outperform the existing wireless router that you already have in terms of range.
Also as you know, the speed of your Internet connection is limited to the plan that you have with Verizon. An Apple router cannot take the speed of Internet connection that it receives from your Verizon plan and make it go any faster.
A user who has both the same Verizon router as you and an AirPort Extreme might be able to tell you how the products compare in his home.
But...and this is a big BUT...... the bottom line with any wireless router is that you will not know how well it performs in your home until you try it out in your home. To think otherwise would be foolhardy at best.
Buy from Apple and you have a 14 day return privilege in case things don't work as well as hoped. Other stores may offer a similar option. Check first, before you buy.
