Watch the Port Using and deploy packages in JBOSS

Watch the Port Using and deploy packages in JBOSS

I stayed in Ubuntu System these days.
One problem accured.

My 80 port is using when I tryed to start my jboss server. The error message is:
Server port In Use 80-Http

So I tryed to figure out which service/software is using this port.

First I install a tool
>sodu apt-get install nmap

Executing the check command
>nmap localhost

The result is as follow:
Starting Nmap 5.21 ( http://nmap.org ) at 2011-03-15 17:39 CST
Nmap scan report for localhost (127.0.0.1)
Host is up (0.00037s latency).
Hostname localhost resolves to 2 IPs. Only scanned 127.0.0.1
rDNS record for 127.0.0.1: localhost.localdomain
Not shown: 994 closed ports
PORT      STATE SERVICE
80/tcp    open  http
631/tcp   open  ipp
1723/tcp  open  pptp
3306/tcp  open  mysql
7070/tcp  open  realserver
45100/tcp open  unknown

So, it is http, it is apache2.

>sudo /etc/init.d/apache2 stop

Still, I have problem with these messages:

Problem One:

Solution:
It's a fundamental Linux/Unix design choice. All ports below 1024 can only be bound by a process with "root" permissions.
So I changed my port to 8080.


Problem Two:
18:07:32,960 ERROR [BasicLazyInitializer] Javassist Enhancement failed: net.tss.app.service.store.ejb.entity.Store
java.lang.RuntimeException: java.lang.IllegalArgumentException: Can not set static javassist.util.proxy.MethodFilter field net.tss.app.service.store.ejb.entity.Store_$$_javassist_0._method_filter to org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer$1

Solution:
That is my project problem, I have package conflicks. So I remove javassist and ongl in xwork-core.jar

Problem Three:

Solution:
That is connection problem. We restart the jboss server. It works fine.
