ANT = social insects of the family Formicidae (pronounced /fɔrˈmɪsɨdiː/) and, along with the related wasps and bees, belong to the order Hymenoptera. 



WLST = The WebLogic Scripting Tool (WLST) is a command-line scripting environment that you can use to create, manage, and monitor WebLogic Server domains

Oh giordano Boy, this part i know .. Please just dont google and write me just a full form of it.
I have configured it in Weblogic server and even deploy applciation from ant command.
i want to discuss more abt it .

thanks,

Thanks folks!
Finally I got  binary file of WLS. Two lines of command. :)

Thank you all for your help

I am new to Java Web dev.  So sorry for the questios if it sounds dumb.
What are the advantages of using self build ANT Script to the script provided by IDEs?

Is it possible to build war or ear file by combining files in different project by using ANT?

Default061,
                   WLST is based on Jython and we use JMS and WLST for automation.
We used WLST for deploying applciation into UAT/Production boxes. If you come over to the application side its is nothing but a simple WAR/RAR file (Scripting in Unix/Linux platform).
ANT is also  built in tools by Java and this have lots of advantages and supports all platforms.
The tools i am talking abt is all about management tools.(ADMIN PART) like clearing faults, deleting apps and undeploy and deploy applocation.
Java developers also uses this ANT tooll to depoy application in IDE.

Folks i just to be VMWARE Admin too in 2009.
Shoot out your problems...
Lets Virtualize and clone ours Brains and make it more effective.....!!!!
 

@default 061.

Yeah, there is inbuilt ANT in ide. Ant needs build.xml file to build the war, ear file. Once war, ear file is built, we deploy those war/ear files in  web/application server. war/ear are nothing but zipped files. Once we deploy they unpack hence ready to get accessed.

Ant is a build tool that creates war/ear file for deployment and it needs build.xml. When we write build.xml by ourselves, we can configure the way we want. Let's say we want to create a target(ant command) :ant start-jboss which means we want to start server from ant, then ant script generated by IDE doesnt help. we have to manually write that target in build.xml. Advantage is, we can configure the build.xml we want.
when we install ant: type   ant -p
that will show u list of targets(commands) in build.xml. So we can manually configure those targets acccording to our need.

ear file generally contains more than one war file. For ant to work according to our wish, we need to configure in build.xml.

Hope this helps !

I am interested in learning how to set up the high performace cluster using CentOS. I am thinking to do in VMWare workstation or ESXi. I aprreciate if anyone can guide me to the steps or send the link to the resources to read.

This is good.
Before learning we need to know how deep we were in Clustering wheter it is Veritas Cluster.,Sun Cluster or through
Vmware using Centos or ESX redundancy.
SO learning how to set up the high performace cluster using CentOS.
This is just an example IP i always take it coz i learn it from this ip
Configuration: Assign hostname node1 to primary node with IP address 192.168.9.172 to eth0.
Assign hostname node2 to slave node with IP address 192.168.9.173
Note: on node1
uname -n on both server
192.168.9.173  its virtual IP address that will be used for our web server  (ie Apache will listen on that address).
Configuration.
Download and install the heartbeat package. In our case we are using CentOS so we will install heartbeat with yum:
yum install heartbeat or for this you have to configure yum if not do below
or download these packages: Its just a version we figure it out by server platform
heartbeat-2.08
heartbeat-pils-2.08
heartbeat-stonith-2.08
 So we have to configure heartbeat on our two node cluster. We will deal with these files.
authkeys
ha.cf
haresources
 Now moving to our configuration. But there is one more thing to do, that is to copy these files to the /etc/ha.d directory. In our case we copy these files as given below:
cp /usr/share/doc/heartbeat-2.1.2/authkeys /etc/ha.d/
cp /usr/share/doc/heartbeat-2.1.2/ha.cf /etc/ha.d/
cp /usr/share/doc/heartbeat-2.1.2/haresources /etc/ha.d/
 start configuring heartbeat. First we will deal with the authkeys file
. For this we will make changes in the authkeys file as below.
EDIT /etc/ha.d/authkeys
auth 2
2 sha1 test-ha  add it
chmod 600 /etc/ha.d/authkeys
 Moving to our second file (ha.cf) which is the most important. So edit the ha.cf file with vi:
vi /etc/ha.d/ha.cf
logfile /var/log/ha-log
logfacility local0
keepalive 2
deadtime 30
initdead 120
bcast eth0
udpport 694
auto_failback on
node node01

node1 and node2 save and quit!
 Now edit the haresources file. This file contains the information about resources which we want to highly enable. In our case we want the webserver (httpd) highly available:
Edit /etc/ha.d/haresources
node1 192.168.9.174 httpd save it !!!
winscp/sftp/scp -r /etc/ha.d/ root@node02:/etc/       from both node
Finally Edit /etc/httpd/conf/httpd.conf
Listen 172.16.4.82:80 save  save same in node 2 tooo
scp -r /etc/httpd/conf/httpd.conf root@node02:/etc/httpd/conf/
we have to create Index on both server
echo “node1 apache test server” > /var/www/html/index.html
echo “node2 apache test server” > /var/www/html/index.html
 start heartbeat on both server
/etc/init.d/heartbeat start
NOW
http://192.168.9.174
This will show node01 apache test server.
In your browser type in the URL http://192.168.9.174

If you dont understand the process just knock me i will be able to help you.
But frankly speaking i have done clustering through ESX Server, Big corporate recommend this one.
Once you know the concept of clusternig than getting command is nothing.

Thanks
Geek

too complicated for me :) neway , gonna bring up the thread

@default,

thanks mate.

in simple words, ant just zips the whole project like winzip and when we deploy, it unzips.
when ant zips the whole project ( like winzip), it is called war file.

Oracle just realase most Sophisticated High Availability (HA) weblogic tools called WebCenter Suite.

It is just an Oracle Fusion Middleware and a mix of existing Oracle software along with the various products from BEA.

thanks,
Geek
 

Awesome Hibernate Framework Tutorial:

 that is good tutorial Ayush.

Do you have any  link for HQL queries tutorial?

For Ant,
http://ant.apache.org/manual/tutorial-HelloWorldWithAnt.html

Not worked with Hibernate Query Language, but simple google search returned me this

is fine for Hibernate Query tutorial.

Hey Guys ..!!

Anybody had problems in java interview or Unix/Linux interview...?/ post here...
Lets discuss how to overcome interview questions??

I had one ,
 A extends B , B extends  C and  C extends A
What kind of relation is that?

Could not answer it,Some where I saw java doesnot support and I couldnot run that example. Some language Does support .
( cyclic inheritence or sth was the term, forgot again ;))

java doesnt supprt such kind of inheritance.
java goes upto multi level inheritance but doesnt support multiple inheritance/.
If class  A is a super class then class B can extend class A and class C can extend class B.[multi level inheritance]

I think the problem in that question was cyclic inheritence rather than multiple.
But yep, both are not supported in Java, but kind of multiple inheritence is supported ( not exact ) by using interface if I am not wrong.
